Places where compiler needs it already have access to Environment object
and can use it directly.
This fixes mypy complaining that not all compilers have self.exe_wrapper
in run() method that got moved to base class.
When linking with a Rust rlib, we should also link with its external
system dependencies. This was currently done only for C ABI crates, do
it for both rlib and staticlib now.
Using scan-build gives the following warning:
"Running the setup command as `meson [options]` instead of
`meson setup [options]` is ambiguous and deprecated."
This commit fixes this issue by adding the setup keyword to the meson command.
The type of quoting was changed in 522392e to one that is suitable for
use with cmd.exe on Windows. However, the documentation states that the
type of quoting in MESONINTROSPECT is compatible with shlex.split() and
elsewhere in the code, the same variable is still quoted with
shlex.quote(). As mostly identified in #12148, there are a few choices:
1. Use shlex.quote() consistently and support Python but not cmd.exe.
2. Use join_args and support cmd.exe but not Python.
3. Use join_args and support splitting through the mesonbuild Python library.
This commit implements the first option and reverts part of 522392e.
Regression testing is implemented in #12115.
Fixes#12148
Xcode 14 has dropped the legacy build system, forcing us to use the
new one introduced in Xcode 9. The new system requires that we conform
to its "clean build folder" behavior, or clean operations fail.
CMake achieves this by setting other variables instead of SYMROOT, so
we follow that approach while retaining our current behavior as much
as possible.

Some backends may need to use its own target directories instead of
our default one. For this, introduce an optional argument "targetdir"
that will still use our default one when not specified.
Currently, the backend has "x86_64" hardcoded as the architecture,
which breaks cross compiling and compiling normally on arm64. Fix
this by setting it to the host machine's CPU architecture instead.
This patch adds 'depends' keyword to compiler.preprocess().
It allows to execute other targets before doing the preprocessing.
Test-case is added to demonstrate that functionality: it
generates the header before preprocessing the C source that
uses that generated header.
Thanks to @bruchar1 for getting this patch to work.
This change fixes two usability issues with the genvslite project
generation. Unlike when using the full VS backend, under genvslite the
ProjectName property wasn't being set for generated projects. This means
projects end up being named according to the project files, which
includes suffixes like "@exe" in the solution, which is undesirable.
This change adds the ProjectName field in for genvslite projects, to
keep the naming consistent with projects under the VS backend.
Additionally, previously under genvslite, no projects were set to build
under any solution configuration by default. This is inconvenient, as
the user has to manually edit the build settings for each solution
configuration before they can compile at the solution level. There was a
note in the code to do something about this. This change enables
compilation at the solution level for the default startup project in the
solution, so the user can now just press F5 to build the solution and
run the default startup project, as they would typically expect.
On Linux many .so's are augmented with version information,
e.g. libxyz.so.1.2.3. CMake will happily refer to these versioned .so's
in its dependencies instead of libxyz.so (typically a symlink).
Unfortunately these versioned .so's aren't recognized as libraries by
the Backend's logic to produce build rpaths from library paths.
Fix this by recognizing any .so extension as sufficient reason to
produce a build rpath, not just if .so is the last extension.
* Vala: depend on gresources
Valac uses gresource at compile time to look up .ui files
* Automatically pass `--gresourcesdir` to valac
* gnome.compile_resources: clean up duplicate paths better
* Add a test for improved gresouce handling
Standard include paths need to be added to resolve STL and platform
headers. Additionally, compiler args need to be separated by spaces, not
semicolons, in order to be recognised.
Nvcc doesn't support `-MQ` flag, so we have to manually escape cuda
target name.
This commit escape `$out` to `$CUDA_ESCAPED_TARGET`, so now we can just
use `-MT` flag in nvcc to generate header dependencies.
Anywhere we have that, we also have the Environment object, which is
just wrapped by the Interpreter methods anyway. This avoids inderections
that are unnecessary.
This replaces all of the Apache blurbs at the start of each file with an
`# SPDX-License-Identifier: Apache-2.0` string. It also fixes existing
uses to be consistent in capitalization, and to be placed above any
copyright notices.
This removes nearly 3000 lines of boilerplate from the project (only
python files), which no developer cares to look at.
SPDX is in common use, particularly in the Linux kernel, and is the
recommended format for Meson's own `project(license: )` field
mypy will complain if backends.Backend has a lru_cache wrapped method,
but it is overridden in XCodeBackend with a method that isn't cached.
This is almost certainly a sign that we should be caching it here too
anyway. The generic backend cache was added years ago via an
intimidating commit f39d2cc3bf which
claims that it reduced call time from 60s to 0.000435s and that this was
specifically due to getting a coredata option every single time. This is
probably workload dependent, but getting an option is *not* nearly as
cheap as a throwaway function call.
Xcode does not recognize our private directories, nor does it ever
try to generate them. Instead, just import the build directories
for each swift dependency.
This fixes linking between swift targets when they are in their own
subdirectories, as they will have different build directories in that
case.
When generating aggregated targets, custom targets were not being
checked for dependencies when they should have.
Fixes passing swift test case 4 (generate).
This must be explicitly set in Xcode or it will not be able to compile
mixed targets successfully. This is not needed for pure Swift targets.
Set a new variable "is_swift" so finding the bridging header does not
take O(n^2) time.
Fixes passing swift test case 5 (mixed) with Xcode backend.
Meson supports other transpilers generating source code for which
compilation rules need to be generated other than Vala. Reflect this
in variable names and comments to avoid confusion.
This commit modifies the get_target_filename_for_linking function to
always return POSIX-style paths, even on Windows systems. This is
necessary because the Ninja generator can have issues with Windows-style
paths when using the `/WHOLEARCHIVE:` flag.
This is consistent with the syntax accepted by the cl and clang-cl
compilers, as documented in the Microsoft documentation:
https: //learn.microsoft.com/en-us/cpp/build/reference/cl-filename-syntax?view=msvc-170
Fixes: 12534
This was originally added for vala only, with the rationale that vala
generates bad code that has warnings. Unfortunately, the rationale was
fatally flawed. The compiler warns about a number of things, which the
user can control depending on their code (or their code generator's
code), but some of those things are absolutely critical to warn about.
In particular, GCC 14 and clang 17 are updating their defaults to warn
-- and error by default for -- invalid C code that breaks the standard,
but has been silently accepted for over 20 years "because lots of people
do it". The code in question is UB, and compilers will generate faulty
machine code that behaves erroneously and probably has a mass of CVEs
waiting to happen.
Compiler warnings are NOT safe to just... universally turn off. Compiler
warnings could be either:
- coding style lints
- threatening statements that the code is factually and behaviorally wrong
There is no magic bullet to ignore the former while respecting the
latter. And the very last thing we should ever do is pass `-w`, since
that causes ALL warnings to be disabled, even the manually added
`-Werror=XXX`.
If vala generated code creates warnings, then the vala compiler can
decrease the log level by generating better code, or by adding warning
suppression pragmas for *specific* issues, such as unused functions.
