Split out tests (and parts of tests) which require a native compiler
from the 'common' suite to a new suite called 'native', so we can
selectively avoid running those tests when only a cross-compiler is
available.
Also move test '211 cmake module' to 'cmake' suite, since it appears
that the way we use cmake requires a native compiler.
If the meson.build doesn't use a native compiler, the native compiler
options (e.g. 'c_args') shouldn't be present in the output of 'meson
introspect --buildoptions'.
Add the ids of any target that needs to be rebuilt before running the
tests as computed by the backend, to the introspection data for tests and benchmarks.
This also includes anything that appears on the test's command line.
Without this information, IDEs must update the entire build before running
any test. They can now instead selectively build the test executable
itself and anything that is needed to run it.

when that statement gets evaluated, the interpreter remembers the
version target and if it was part of the evaluation of a `if` condition
then the target meson version is temporally overriden within that
if-block.

This type happened in https://github.com/mesonbuild/meson/pull/7432
and wasn't noticed because I didn't add a test for it. Rectified now.
If we don't specify the CRT, MSVC will pick /MT by default (!?) and
link to `libcmt.lib`. This actually *breaks* UWP because `libcmt.lib`
is not available by default when building for UWP.
Was noticed here: https://github.com/cisco/libsrtp/pull/505
- Exceptions raised during subproject setup were ignored.
- Allow c_stdlib in native file, was already half supported.
- Eliminate usage of subproject variable name by overriding
'<lang>_stdlib' dependency name.
Without the parenthesis, the command evaluates to `[]` if
`use_llvm_cov` is `False`.
Also fix tests to actually check whether or not coverage reports are
generated.

There is nothing to "warn" about, this is a completely routine
occurence. OTOH, when something is corrupted, we should warn. Keep
the red color and "WARNING:" prefix in that case.
Example output:

This creates a full set of option in environment that mirror those in
coredata, this mirroring of the coredata structure is convenient because
lookups int env (such as when initializing compilers) becomes a straight
dict lookup, with no list iteration. It also means that all of the
command line and machine files are read and stored in the correct order
before they're ever accessed, simplifying the logic of using them.
This is like the project options, but for meson builtin options.
The only real differences here have to do with the differences between
meson builtin options and project options. Some meson options can be set
on a per-machine basis (build.pkg_config_path vs pkg_config_path) others
can be set on a per-subproject basis, but should inherit the parent
setting.
This allows adding a `[project options]` section to a cross or native file
that contains the options defined for a project in it's meson_option.txt
file.
Since -Wl,-rpath= is not the only valid rpath ldflags syntax we
need to try and match all valid rpath ldflags.
In addition we should prevent -Wl,--just-symbols from being used to
set rpath due to inconsistent compiler support.

Since the CompileArgs class already needs to know about the compiler,
and we really need at least per-lanaguage if not per-compiler
CompilerArgs classes, let's get the CompilerArgs instance from the
compiler using a method.
on some systems, tests may take over an hour to run--only to find
you might have used an unintended Meson version (e.g. release instead
of dev). This change prints the Meson version at the start of the
run_*tests*.py scripts.
Also, raise SystemExit(main()) is preferred in general over
sys.exit(main())
so: when building compile args, meson is deduplicating flags. When a
compiler argument is appended, a later appearance of a dedup'ed is going
to remove a earlier one. If the argument is prepended, the element
*before* the new one is going to be removed. And that is where the
problem reported in https://github.com/mesonbuild/meson/pull/7119 is
coming in. In the revision linked there, the order of replacement in the
prepend case was revesered.
With this patch, we restore this behaviour again.
Otherwise a wrapper script which takes an executable as an argument will
mistakenly run when that executable is cross compiled. This does not
wrap said executable in an exe_wrapper, just skip it.
Fixes#5982
If an executable is passed as an argument to a script in the build
directory that it resides in then it will not execute (on *nix) due to a
lack of ./. Ie, `foo` must be called as `./foo`. If it is called from a
different directory it will work. Ie `../foo` or `bar/foo`.
Fixes#5984
Gtest can output junit results with a command line switch. We can parse
this to get more detailed results than the returncode, and put those in
our own Junit output. We basically just throw away the top level
'testsuites' object, then fixup the names of the tests, and shove that
into our junit.
If the feature hadn't been broken in the first place it would have
worked on them anyway, so we might as well expose it. I'm loathe to do
it because one of the best features of meson in a mixed C/C++ code base
is that meson figures out the right linker every time, but there are
cases people have where they want to force a linker. We'll let them keep
the pieces.
JUnit is pretty ubiquitous, lots of services and results viewers
understand it, in particular gitlab and jenkins know how to consume
JUnit xml. This means projects using CI services can have their test
results consumed automatically.
Fixes: #6972
A current rather untyped storage of options is one of the things that
contributes to the options code being so complex. This takes a small
step in synching down by storing the compiler options in dicts per
language.
Future work might be replacing the langauge strings with an enum, and
defaultdict with a custom struct, just like `PerMachine` and
`MachineChoice`.
This does a couple of nice things, one is that editors like vscode can
be configured to use this schema to provide auto completion and error
highlighting if invalid values are added or required values are missing.
It also allows us test that the format of the test matrix work in a unit
test, which I've added. It does require that the python jsonschema
package is installed.
It can happen that a server is temporaly down, tarballs often have
many mirrors available so we should be able to add at least one fallback
mirror in wrap files.
* cmake: enhance support of cmake config file syntax

PR #6363 made it so our interpretation of env vars no longer clashed
with Autoconf's: if both Meson and Autoconf would read and env var, both
would do the same things with the value they read.
However, there were still cases that autoconf would read an env var when
meson wouldn't:
- Autoconf would use `CC` in cross builds too
- Autoconf would use `CC_FOR_BUILD` in native builds too.
There's no reason Meson can't also do this--if native cross files
overwrite rather than replace env vars, cross files can also overwrite
rather than replace env vars.
Because variables like `CC` are so ubiquitous, and because ignoring them
in cross builds just makes those builds liable to break (and things more
complicated in general), we bring Meson's behavior in line with
Autoconf's.
A couple used checks for specific compiler binaries, but those might not
be accurate for cross compiling. All the languages other than C and C++
(which we basically always assume we have) should have a
skip_if_not_lang check.
It may not be obvious to users that these two ways to set build-types
override each other and specifying both is redundant, and conflicts
are resolved based on whichever is specified later.

With the current logic passing `--debug` will actually be parsed as
`-Ddebug=false`, which is absolutely not what is expected.

The previous code was assuming that options do not depend on each
other, and that you can set defaults using `dict.setdefault()`. This
is not true for `buildtype` + `optimization`/`debug`, so we add
defaults + overrides in the right order and use the options parsing
code later to compute the values.
Includes a test.
Closes https://github.com/mesonbuild/meson/issues/6752
Similar to meson.override_find_program() but overrides the result of the
dependency() function.
Also ensure that dependency() always returns the same result when
looking for the same dependency, this fixes cases where parts of the
project could be using a system library and other parts use the library
provided by a subproject.
This makes the typing annotations basically impossible to get right, but
if we only have one key then it's easy. Fortunately python provides
comprehensions, so we don't even need the ability to pass multiple keys,
we can just [extract_as_list(kwargs, c) for c in ('a', 'b', 'c')] and
get the same result.
listify shouldn't be unholdering, it's a function to turn scalar values
into lists, or flatten lists. Having a separate function is clearer,
easier to understand, and can be run recursively if necessary.
The old logic was completely broken, and didn't even assert that the
specified section was found at all. The CPU families test was broken
because of this. Luckily, the table didn't go out of sync with the
code.
It now also doesn't assume that each section has only one table. This
fixes the test now that we document the buildtype/optimization/debug
mapping in a second table inside the `Universal options` section.
* unittests: fix finding python2 if the binary is named python2
Because of the way the python module works the simplicity of the test
function is no longer valid, we need to have and additional name
parameter to make the python module work, as it doesn't look for an
entry called "python2" or "python3", only "python"
* unittests: Don't make our python 2.x check debian specific
* unittests: On macOS the python2 binary is still called python
This adds a warnings counter for subprojects that passed. This is to
encourage developpers to check warnings in the logs and hopefully fix
them. Otherwise they could be hidden in hundreds lines of logs.
This also print the error message for subprojects that did not pass. The
error message is often enough to fix the issue (e.g. missing
dependency) and it's easier than searching in the logs why a subproject
failed.
When a source file for a library is changed without adding new extern
symbols, only that library should be rebuilt. Nothing that uses it
should be relinked.
Along the way, also remove trailing `.` in all Ninja rule
descriptions. It's very confusing to see messages like:
```
Linking target mylib.dll.
```
It's confusing that the period at the end of that is not part of the
filename. Instead of removing that period manually in the tests (which
feels wrong!) just don't print it at all.
This makes two basic changes, 1 it moves the name of the linker into the
linker class, this should reduce the number of errors and typos, and
ensure that a linker always has one name. This then renames the linkers
to have more consistent names.
Posix/gnu linkers are called ld.<name>: ld.gold, ld.lld, ld.solaris.
Apple linkers are renamed ld64.
This allows users to disable writing out the inbuilt variables to
the pkg-config file as they might actualy not be required.
One reason to have this is for architecture-independent pkg-config
files in projects which also have architecture-dependent outputs.
For example : https://gitlab.freedesktop.org/wayland/weston/issues/269Fixes#4011

Error is raised due to Elbrus Fortran compiler can't
generate debug information for now, because it's a 2-step
compiler where 1st step is code conversion from Fortran to C,
so debug information which C compiler would produce, is useless.
When a dependency is required, not found on the system, and its fallback
is disabled with --wrap-mode=nofallback, meson should abort instead of
returning not-found.
pkgconf automatically prunes "system library paths" from its output. The
system library paths depend on the system toolchain. A common value on a
64-bit system is as follows:
/lib64:/usr/lib64:/usr/local/lib64
So, if -L/usr/lib64 appears in the Libs section, it will be pruned from
the output of pkg-config --libs.
The pc files generated for this test contain something like this:
libdir=/usr/lib
Libs: -L${libdir} ...
pkgconf may not consider /usr/lib to be a system library path, so it is
not pruned as the test expects. To work around this, override the
compiled-in list of paths via the PKG_CONFIG_SYSTEM_LIBRARY_PATH
environment variable.
Fixes: https://github.com/mesonbuild/meson/issues/6004
The rust code is ugly, because rust is annoying. It doesn't invoke a
linker directly (unless that linker is link.exe or lld-link.exe),
instead it invokes the C compiler (gcc or clang usually) to do it's
linking. Meson doesn't have good abstractions for this, though we
probably should because some of the D compilers do the same thing.
Either that or we should just call the c compiler directly, like vala
does.
This changes the public interface for meson, which we don't do unless we
absolutely have to. In this case I think we need to do it. A fair number
of projects have already been using 'ld' in their cross/native files to
get the ld binary and call it directly in custom_targets or generators,
and we broke that. While we could hit this problem again names like
`c_ld` and `cpp_ld` are far less likely to cause collisions than `ld`.
Additionally this gives a way to set the linker on a per-compiler basis,
which is probably in itself very useful.
Fixes#6442
When there is more than one path in PKG_CONFIG_PATH. It is almost always
preferred to find things in the order specified by PKG_CONFIG_PATH
instead of assuming pkg-config returns flags in a meaningful order.
For example:
/usr/local/lib/libgtk-3.so.0
/usr/local/lib/pkgconfig/gtk+-3.0.pc
/usr/local/lib/libcanberra-gtk3.so
/usr/local/lib/pkgconfig/libcanberra-gtk3.pc
/home/mesonuser/.local/lib/libgtk-3.so.0
/home/mesonuser/.local/lib/pkgconfig/gtk+-3.0.pc
PKG_CONFIG_PATH="/home/mesonuser/.local/lib/pkgconfig:/usr/local/lib/pkgconfig"
libcanberra-gtk3 is a library which depends on gtk+-3.0. The dependency
is mentioned in the .pc file with 'Requires', so flags from gtk+-3.0 are
used in both dynamic and static linking.
Assume the user wants to compile an application which needs both
libcanberra-gtk3 and gtk+-3.0. The application depends on features added
in the latest version of gtk+-3.0, which can be found in the home
directory of the user but not in /usr/local. When meson asks pkg-config
for linker flags of libcanberra-gtk3, pkg-config picks
/usr/local/lib/pkgconfig/libcanberra-gtk3.pc and
/home/mesonuser/.local/lib/pkgconfig/gtk+-3.0.pc. Since these two
libraries come from different prefixes, there will be two -L arguments
in the output of pkg-config. If -L/usr/local/lib is put before
-L/home/mesonuser/.local/lib, meson will find both libraries in
/usr/local/lib instead of picking libgtk-3.so.0 from the home directory.
This can result in linking failure such as undefined references error
when meson decides to put linker arguments of libcanberra-gtk3 before
linker arguments of gtk+-3.0. When both /usr/local/lib/libgtk-3.so.0 and
/home/mesonuser/.local/lib/libgtk-3.so.0 are present on the command
line, the linker chooses the first one and ignores the second one. If
the application needs new symbols that are only available in the second
one, the linker will throw an error because of missing symbols.
To resolve the issue, we should reorder -L flags according to
PKG_CONFIG_PATH ourselves before using it to find the full path of
library files. This makes sure that we always follow the preferences of
users, without depending on the unreliable part of pkg-config output.
Fixes https://github.com/mesonbuild/meson/issues/4271.
There are two awful things about CompilerArgs, one is that it directly
inherits from list, and there are a lot of subtle gotcahs with
inheriting from builtin types. The second is that the class allows
arguments to be passed in whatever order. That's bad. This also fully
annotates the CompilerArgs class, so mypy can type check it for us.
This dumps xild on mac and linux. After a lot of reading and banging my
head I've discovered we (meson) don't care about xild, xild is only
useful if your invoke ld directly (not through icc/icpc) and you want to
do ipo/lto/wpo. Instead just make icc report what it's actually doing,
invoking ld or ld64 (for linux and mac respectively) directly. This
allows us to get -fuse-ld working on linux.
Previously if a user tried to pass a command line build
option that contained a '%' character the command line
parser assumed that there was string interpolation to be
done. As there is no sense in such a scenario no code
provides any input for the interpolation. This then leads to
a failure.
In this commit we specifically override the defaults in
ConfigParser and set interpolation to None, which disables
command line build option interpolation.
Fixes#6157
A build with a cross file should always be identified as a cross build, even if
the host and build machine are identical. This was the case in 0.50, regressed
in 0.51, and is fixed again in 0.52, so add a test case to ensure it doesn't
regress again.
Now that the linkers are split out of the compilers this enum is
only used to know what platform we're compiling for. Which is
what the MachineInfo class is for
test3-static was actually always using the shared library because that
warning was not fatal:
WARNING: Static library 'func6' not found for dependency 'func6', may
not be statically linked
The reason why the libfunc6.a wasn't found is because the prefix in the
generated pc file was not set to install dir.
In qemu, minikconf generates a depfile that meson could use to
automatically reconfigure on dependency change.
Note: someone clever can perhaps find a way to express this with a
ninja rule & depfile=. I didn't manage, so I wrote a simple depfile
parser.
According to http://testanything.org/tap-specification.html
"Any output line that is not a version, a plan, a test line, a
diagnostic or a bail out is considered an “unknown” line. A TAP parser
is required to not consider an unknown line as an error but may
optionally choose to capture said line and hand it to the test
harness, which may have custom behavior attached [...] TAP::Harness
reports TAP syntax errors at the end of a test run".
(glib gtest can generate empty lines)
The main library must come before extra libraries, because they are
likely to be dependencies of the main library that get promoted from
private to public. This was causing static link issues with glib-2.0.pc.
On illumos (and presumably Solaris, though I can't test) cc normally
points to Sun CC, which we don't support. So ensure that gcc is used
explicitly in that case.
* Do not strip static archives
Stripping static archives without more fine-grained options (e.g. `-g`)
leads to failures such as
ld: libfoo.a: error adding symbols: archive has no index; run ranlib to add one
because GNU strip removes *every* symbol in a static archive by default.
Given that static archives are not final build artifacts (unlike
executables and shared libraries), stripping them gains little and only
causes more edge case failures.
* Gentoo's portage only strips debug information:

* Debian also only does some very light stripping:

Instead of the DynamicLinker returning a hardcoded value like
`-Wl,-foo`, it now is passed a value that could be '-Wl,', or could be
something '-Xlinker='
This makes a few things cleaner, and will make it possible to fix using
clang (not clang-cl) on windows, where it invokes either link.exe or
lld-link.exe instead of a gnu-ld compatible linker.
Clang doesn't really like having no-undefined plus the address sanitizer, but
gcc doesn't mind. This all happens to work with clang + gnu ld, but with clang
+ apple ld this turns into a dumpster fire. Just add b_lundef=false to make
everyone happy.
@TingPing has a repository that contains a grammar for meson which is
used by linguist (GitHub), and by many editors such as Atom, VS Code,
TextMate, Sublime Text, etc. Add CI so that we notice that the
function list in it is out of date, such as https://github.com/TingPing/language-meson/pull/3
It's harder to do this generically for other syntax such as the `in`
keyword, but it's better than nothing.
This reverts the changes to the `section` key for the
buildoptions and moves the machine choice into it's
own `machine` key.
With this commit the __undocumented__ breaking change
to the introspection format (introduced in 0.51.0) is
reverted and a new key is added instead.
Instead of trying to guess whether we need py or python3, and then
falling over when whatever we guessed isn't in the path or isn't right,
just use sys.executable which should always work.
* coredata: Correctly handle receiving a pipe for native/cross files
In some cases a cross/native file may be a pipe, such as when using bash
process replacement `meson --native-file
<([binaries]llvm-config='/opt/bin/llvm-config')`, for example. In this
case we copy the contents of the pipe into a file in the meson-private
directory so we can create a proper ninja dependency, and be able to
reload the file on --wipe/--reconfigure. This requires some extra
negotiation to preserve these native/cross files.
Fixes#5505
* run_unitests: Add a unit test for native files that are pipes
Using mkfifo.
We were setting the base options for the Objective-C compiler
manually, due to which options such as b_bitcode and b_ndebug were not
getting set at all.
The base options here are the same as for C code with the Clang
compiler, so just use the same inherited list.
Also expand the bitcode test to ObjC and ObjC++ so this doesn't happen
again.
In most cases instead pass `for_machine`, the name of the relevant
machines (what compilers target, what targets run on, etc). This allows
us to use the cross code path in the native case, deduplicating the
code.
As one can see, environment got bigger as more information is kept
structured there, while ninjabackend got a smaller. Overall a few amount
of lines were added, but the hope is what's added is a lot simpler than
what's removed.
It was using ':' as a path separator while GCC uses ';' resulting in bogus
paths being returned. Instead assume that the compiler uses the platform native
separator.
The previous splitting code still worked sometimes because splitting
"C:/foo;C:/bar" resulted in the last part "/bar" being valid if "<DriveOfCWD>:/bar"
existed.
The fix also exposes a clang Windows bug where it uses the wrong separator:
https://reviews.llvm.org/D61121 . Use a regex to fix those first.
This resulted in linker errors when statically linking against a library which
had an external dependency linking against system libs.
Fixes#5386
Currently this test assumes that the user doesn't have XDG_DATA_HOME
set in their path, but this isn't a good assumption, and can result in
the test not actually testing what it means to.
