These result in very large binaries when linked, and are not generally
useful. A user can turn them back on by passing `-C overflow-checks=yes`
manually via `-Drust_args` or the `RUSTFLAGS` environment variable

Cython historically, when asked to print the version and exit
successfully, would do so on stderr, which is weird and inconsistent.
Recently, it fixed this UX bug by printing on stdout instead:
https://github.com/cython/cython/issues/5504
This then broke meson detection because we assumed it was on stderr due
to historically being there:
https://github.com/scipy/scipy/issues/18865
Cython is right, and shouldn't have to revert this reasonable change for
backwards compatibility. Instead, check both.
Instead of hardcoding any values, hardcode what we think the most likely
implementation is, and check that first. It was pointed out that while
for example, Apple only provides libc++ and supports that for xcode, a
user could install a custom environment (such as homebrew) which uses
it's own copy of libstdc++, and we need to account for that. This means
that a library search will be done, but only once and the result will be
cached, on all systems.
Fixes get_define() for MSVC. cl with /std:c11 and newer add a trailing
space character when substituting, even if macro is empty. This breaks
parsing preprocessed output to extract value. Since they cannot contain
spaces it is safe to simply strip parsed value.
Fixes: #10179
Currently, we hardcode libc++ for MacOS (and derivatives), and libstdc++
for all other cases. Clang had some hackery to make this work in many
cases. However, this doesn't always work, namely if you try to to use
Rust as the linker when libc++ is required.
This implementation does, as an optimization, provide a hardcoded list
of OSes we know always use libc++, and otherwise will attempt to detect
it. As a second optimization, the detected values are cached, so the
lookup is only done once

* Capture all compile args from the first round of ninja backend generation for all languages used in building the targets so that these args, defines, and include paths can be applied to the .vcxproj's intellisense fields for all buildtypes/configurations.
Solution generation is now set up for mutiple build configurations (buildtypes) when using '--genvslite'.
All generated vcxprojs invoke the same high-level meson compile to build all targets; there's no selective target building (could add this later). Related to this, we skip pointlessly generating vcxprojs for targets that aren't buildable (BuildTarget-derived), which aren't of interest to the user anyway.
When using --genvslite, no longer inject '<ProjectReference ...>' dependencies on which a generated .vcxproj depends because that imposes a forced visual studio build dependency, which we don't want, since we're essentially bypassing VS's build in favour of running 'meson compile ...'.
When populating the vcxproj's shared intellisense defines, include paths, and compiler options fields, we choose the most frequent src file language, since this means more project src files can simply reference the project shared fields and fewer files of non-primary language types need to populate their full set of intellisense fields. This makes for smaller .vcxproj files.
Paths for generated source/header/etc files, left alone, would be added to solution projects relative to the '..._vs' build directory, where they're never generated; they're generated under the respective '..._[debug/opt/release]' ninja build directories that correspond to the solution build configuration. Although VS doesn't allow conditional src/header listings in vcxprojs (at least not in a simple way that I'm aware of), we can ensure these generated sources get adjusted to at least reference locations under one of the concrete build directories (I've chosen '..._debug') under which they will be generated.
Testing with --genvslite has revealed that, in some cases, the presence of 'c:\windows\system32;c:\windows' on the 'Path' environment variable (via the make-style project's ExecutablePath element) is critical to getting the 'meson compile ...' build to succeed. Not sure whether this is some 'find and guess' implicit defaults behaviour within meson or within the MSVC compiler that some projects may rely on. Feels weird but not sure of a better solution than forcibly adding these to the Path environment variable (the Executable Path property of the project).
Added a new windows-only test to windowstests.py ('test_genvslite') to exercise the --genvslite option along with checking that the 'msbuild' command invokes the 'meson compile ...' of the build-type-appropriate-suffixed temporary build dir and checks expected program output.
Check and report error if user specifies a non-ninja backend with a 'genvslite' setup, since that conflicts with the stated behaviour of genvslite. Also added this test case to 'WindowsTests.test_genvslite'
I had problems tracking down some problematic environment variable behaviour, which appears to need a work-around. See further notes on VSINSTALLDIR, in windowstests.py, test_genvslite.
'meson setup --help' clearly states that positional arguments are ... [builddir] [sourcedir]. However, BasePlatformTests.init(...) was passing these in the order [sourcedir] [builddir]. This was producing failures, saying, "ERROR: Neither directory contains a build file meson.build." but when using the correct ordering, setup now succeeds.
Changed regen, run_tests, and run_install utility projects to be simpler makefile projects instead, with commands to invoke the appropriate '...meson.py --internal regencheck ...' (or install/test) on the '[builddir]_[buildtype]' as appropriate for the curent VS configuration. Also, since the 'regen.vcxproj' utility didn't work correctly with '--genvslite' setup build dirs, and getting it to fully work would require more non-trivial intrusion into new parts of meson (i.e. '--internal regencheck', '--internal regenerate', and perhaps also 'setup --reconfigure'), for now, the REGEN project is replaced with a simpler, lighter-weight RECONFIGURE utility proj, which is unlinked from any solution build dependencies and which simply runs 'meson setup --reconfigure [builddir]_[buildtype] [srcdir]' on each of the ninja-backend build dirs for each buildtype.
Yes, although this will enable the building/compiling to be correctly configured, it can leave the solution/vcxprojs stale and out-of-date, it's simple for the user to 'meson setup --genvslite ...' to fully regenerate an updated, correct solution again. However, I've noted this down as a 'fixme' to consider implementing the full regen behaviour for the genvslite case.
* Review feedback changes -
- Avoid use of 'captured_compile_args_per_buildtype_and_target' as an 'out' param.
- Factored a little msetup.py, 'run(...)' macro/looping setup steps, for genvslite, out into a 'run_genvslite_setup' func.
* Review feedback: Fixed missing spaces between multi-line strings.
* 'backend_name' assignment gets immediately overwritten in 'genvslite' case so moved it into else/non-genvslite block.
* Had to bump up 'test cases/unit/113 genvslites/...' up to 114; it collided with a newly added test dir again.
* Changed validation of 'capture' and 'captured_compile_args_...' to use MesonBugException instead of MesonException.
* Changed some function param and closing brace indentation.
* Archive shared library in AIX
This code change to ensure we archive shared libraries in AIX.
The things we do are:
Archive shared library
Install archived shared library
Build all must build the archived shared library
blibpath must have the archived shared library dependency.
* Archive shared library in AIX.
Made changes as per the review comments given in the first
PR request.
They are:-
Use self.environment.machines[t.for_machine].is_aix()
Remove trial spaces
Use of val instead of internal
Changed comments wherever requested
* Space after octothorpe
* Fixed failed test case causing build break during install section
* Moved AIX specific code to AIXDynamicLinker from backend
* Fix indentation, trailing spaces, add type annotations and Linux/macOS build break
* Remove some more trailing space issues
* Fixed the wrong return type in linkers
This saves on a 1500-line import at startup and may be skipped entirely
if no compiled languages are used. In exchange, we move the
implementation to a new file that is imported instead.
Followup to commit ab20eb5bbc.
The version output scraping for identifying strings checked for "IFORT"
in parentheses after the executable name, which is probably a mistake by
Intel. Current versions of ifx have "IFX" in parentheses there.
Detect both.
Fixes#11873
Rust has a `debug_assert!()` macro, which is designed to be toggled on
the command line. It is on by default in debug builds, and off by
default in release builds, in cargo. This matches what meson's b_ndebug
option does in `if-release` mode.
C like compilers only off `-DNDEBUG` to disable asserts. This is not a
universal paradigm however. Rust, for example has an argument that takes
a boolean. To better represent this, we allow passing a `disable`
boolean. `disable` was chosen rather than `enable` because it allowed
all existing logic to be left in place
This will help with the writing of tools to generate
VisualStudio project and solution files, and possibly
for other IDEs as well.
- Used compilers a about `host`, `build` and `target` machines
arere listed in `intro-compilers.json`
- Informations lister in `intro-machines.json`
- `intro-dependencies.json` now includes internal dependencies,
and relations between dependencies.
- `intro-targets.json` now includes dependencies, `vs_module_defs`,
`win_subsystem`, and linker parameters.
By default clippy-driver will report its own version, which is not very
useful to check the toolchain version. Instead make sure to extract the
actual toolchain version here.
Rust doesn't have a concept of dependency compile arguments, i.e.
something like headers. Dependencies are linked in and all required
metadata is provided by the linker flags.
