hdf5's config-tools will not show compile arguments (including the
include directory) if called without `-c`. Make sure to get both the
compile and link arguments.
When building on Linux, I see:
rustc -C linker=cc --color=always --crate-type rlib --crate-name rs_math -g --emit dep-info=rs_math.d --emit link -L /usr/lib/x86_64-linux-gnu -o librs_math.rlib -l static=m ../rs_math.rs
error: failed to add native library /usr/lib/x86_64-linux-gnu/libm.a: file too small to be an archive
I think the "file too small to be an archive" message is coming from
libLLVM, and is a case of LLVM not handling this type of "script
archive". So, possibly this is just LLVM not handling a linking case.
The rust_args usage in meson.build is invalid, but required to
reproduce the issue in the test case. Perhaps meson should
automatically add the library include path via the dep_m meson object,
or maybe the meson.build can add the link path in a better way.
Changing '-l static=m' to '-l dylib=m' appears to fix this case. (See
comments in meson.build.)
The way the tracking is currently done it works if no new subprojects
are added to a configured build directory. For cases where we want to
add a new subproject, it fails because we don't initialize builtins for
that subproject. This corrects that by checking to see if the subproject
already exists, and if it doesn't initializes the bultins for it.
Fixes: #8421
Useful in case of boolean values to distinguish between a boolean
value having been set in the native/cross file and not having been
provided, which can't be achieved by passing a fallback parameter
to .get_external_property().
It's a pure subset of `get_external_property`, and has odd behavior in
host == build configurations. `get_external_property` is clear, and uses
the standard `native : bool` syntax to control host vs build properties
meson compile itself doesn't permit GNU-style argument permutation, i.e.
TARGET to precede options, so why should we expect ninja to?
And indeed, ninja doesn't document support for this -- but it does
accept it anyway, which is confusing and results in people thinking it's
"supposed to" work.
However, if NINJA=samu then this is in fact enforced. samu does not
permit GNU-style argument permutation. As a result, the arguments passed
to mcompile are actively re-ordered before being passed to the
subprocess, and samu dies with a fatal error.
Fix ordering in mcompile.py and add a comment to warn future readers
that the order does, in fact, matter.
Reworks:
* Add MESON_SKIP_TEST error for darwin from polyglot test
* Remove dependencies from executable
Dylan's changes:
* Add support for both static and shared testing
* Test with pkg-config, cmake, and system
* reformat to meson's style

Enables -Db_sanitize=undefined and company.
Also serves as a testcase for NVCC comma-shielding: Because the test-
case declares `b_sanitize=address,undefined`, the host GCC compiler
needs `-fsanitize=address,undefined`, but this stands a danger of being
split by NVCC when wrapped with `-Xcompiler=args,args`. Special,
already-existing comma-shielding codepaths activate to prevent this
splitting.
Closes#8394.
By default all subprojects are installed. If --skip-subprojects is given
with no value only the main project is installed. If --skip-subprojects
is given with a value, it should be a coma separated list of subprojects
to skip and all others will be installed.
Fixes: #2550.
Some time between 0.56 and 0.57 the TAP parser broke when a test exits
with a nonzero status.
The TAP protocol does not specify this behaviour - giving latitude to
implementers, and meson's previous behaviour was to report the exit
status gracefully.
This patch restores the old behaviour and adds a regression test
Currently we don't handle things correctly if we get a string we should
split, and the linker and needs compiler arguments. It would result in
two unsplit strings in a list, instead of the split arguments in a list
Fixes: #8348
This did work previously, so we need to let it continue working. I'm
proposing removing it in 0.60 because the correct solution has always
worked.
I've also been a bit more defensive here, and made setting
`subproject:opt = foo` in the machine files an error, as we have
`[subproject:built-in options]` or `[subproject:project options]` for
that.
os.path.relpath(f, wd) returns path with \ seperator on Windows, but ninja
targets always uses / separator.
See for example https://gitlab.freedesktop.org/ocrete/libnice/-/jobs/7348274.

Clang has a hand `-Wunused-command-line-argument` switch, which when
turned to an error, gets very grump about `-flto-jobs=0` being set in
the compiler arguments (although `-flto=` belongs there). We'll refactor
a bit to put that only in the link arguments.
GCC doesn't have this probably because, a) it doesn't have an equivalent
warning, and b) it uses `-flto=<$numthreads.
Fixes: #8347
This is a) useless because it's only used to print which options are not
default, and b) harmful because it can result in cases where things
break, like in projects that set a standard that the chosen compiler
doesn't support, but the project (or some subset) can be built with a
different standard.
Fixes: #8360
run_target() does some variable substitutions since 0.57.0. This is a
new behavior, and undocumented, caused by sharing more code with
custom_target(). More consistency is better, so document it now.
custom_target() was doing variable substitution in the past, because it
shared some code with generator(), but that was undocumented. Some
refactoring in 0.57.0 caused it to not replace @CURRENT_SOURCE_DIR@,
@SOURCE_DIR@, and @BUILD_DIR@ anymore. This patch adds back
@CURRENT_SOURCE_DIR@ and document it. It does not add back @SOURCE_DIR@
because it is duplicate with @SOURCE_ROOT@ that has a better name. Also
do not add back @BUILD_DIR@ which is duplicate of @PRIVATE_DIR@, and
not @BUILD_ROOT@ surprisingly, adding to the confusion.
A predicate in two comprehensions was dropped, in what looks like a
rebase error on my part. With the predicate added things work correctly.
Fixes: #8344
Or other language flags that use CPPFLAGS (like CXXFLAGS). The problem
here is actually rather simple, `dict.setdefault()` doesn't work like I
thought it did, I thought it created a weak entry, but it actually is
equivalent to:
```python
if k not in dict:
dict[k] = v
```
Instead we'll use an intermediate dictionary (a default dictionary
actually, since that makes things a little cleaner) and then add the
keys from that dict to self.options as applicable.
