Points to the `mesonintrospect.py` script corresponding to the
currently-running version of Meson.
Includes a test for all three methods of running scripts/commands.
Closes https://github.com/mesonbuild/meson/issues/1385
We were adding them to the CompilerArgs instance in the order in which
they are specified, which is wrong because later dependencies would
override previous ones. Add them in the reverse order instead.
Closes https://github.com/mesonbuild/meson/issues/1495
We check for the existence of PDB files in the install script, so we
don't need to do all this mucking about here. That's more robust too
because we don't need to parse build arguments in buildtype=plain
and decide if the PDB file would be generated.
Factor it out into a function in mesonlib.py. This will allow us to
reuse it for generators and for configure_file(). The latter doesn't
implement this at all right now.
Also includes unit tests.
And actually test that prog.path() works. The earlier test was just
running the command without checking if it succeeded.
Also make everything use prog.get_command() or get_path() instead of
accessing the internal member prog.fullpath directly.
Also, now the linker options are added from various sources in the same
order as compiler arguments for compile commands. As a result, all
libraries and library paths from external and internal sources are added
after all the linker options have been added.
As a result option_link_args() are added when libraries are added to the
list since currently the only thing they add are the libraries specific
in cpp_winlibs/c_winlibs. This fixes an issue where compilation with the
MinGW toolchain (which uses static libraries for winlibs) would result
in undefined symbol errors because the static libraries would be added
in the very beginning and hence would not be scanned for symbols.
Detailed comments have been added that explain where each option is
coming from and why it's been added at that specific point.
More improvements are necessary here because we currently still
unnecessarily repeat libraries from dependencies over and over, which
is a major problem in gst-build because inter-subproject dependencies
cause linker command-lines to almost exceed the argument list length
limit imposed by the kernel. It is also causing us to unnecessarily
add static libraries which have already been linked into a shared
library. See: self.build_target_link_arguments()
At the same time, also fix the order in which compile arguments are
added. Detailed comments have been added concerning the priority and
order of the arguments.
Also adds a unit test and an integration test for the same.
Always generate the vcxproj file, but only add it to the build
configuration if it's either supposed to be built by default, or is
a dependency of another target that is built by default.
The purpose of this class is to make it possible to sanely generate
compiler command-lines by ensuring that new arguments appended or added
to a list of arguments properly override previous arguments.
For instance:
>>> a = CompilerArgs(['-Lfoo', '-DBAR'])
>>> a += ['-Lgah', '-DTAZ']
>>> print(a)
['-Lgah', '-Lfoo', '-DBAR', '-DTAZ']
Arguments will be de-duped if it is safe to do so. Currently, this is
only done for -I and -L arguments (previous occurances are removed when
a new one is added) and arguments that once added cannot be overriden
such as -pipe are removed completely.
With the 'install_mode' kwarg, you can now specify the file and
directory permissions and the owner and the group to be used while
installing. You can pass either:
* A single string specifying just the permissions
* A list of strings with:
- The first argument a string of permissions
- The second argument a string specifying the owner or
an int specifying the uid
- The third argument a string specifying the group or
an int specifying the gid
Specifying `false` as any of the arguments skips setting that one.
The format of the permissions kwarg is the same as the symbolic
notation used by ls -l with the first character that specifies 'd',
'-', 'c', etc for the file type omitted since that is always obvious
from the context.
Includes unit tests for the same. Sadly these only run on Linux right
now, but we want them to run on all platforms. We do set the mode in the
integration tests for all platforms but we don't check if they were
actually set correctly.
Cache the absolute dir that the script is searched in and the name of
the script. These are the only two things that change.
Update the test to test for both #1235 and the case when a script of the
same name is in a different directory (which also covers the subproject
case).
Closes#1235

The script will manually delete all custom_target outputs that are
directories instead of files. This is needed because on platforms other
than Windows, Ninja only deletes directories while cleaning if they are
empty.
Closes#1220
Without this, the user has to both compile the resource with
gnome.compile_resources, pass that to the target sources, and also
pass --gresources=/path/to/gres.xml to vala_args in the target.
With this, we will do that automatically.
This greatly improves the logic for determining the linker. Previously,
we would completely break if a target contained only extracted objects
and we were using more than one compiler in our project.
This also fixes determination of the linker if our target only contains
generated objc++ sources, and other funky combinations.
This avoids us having no compilers at all for targets that are composed
entirely of objects with no sources.
Now we will always have a compiler for a target even if it is composed
entirely of objects generated with custom targets unless it has
completely unknown sources.
Instead of using a whitelist, use a blacklist. Also print a more useful
error if the regex fails to match.
Use an underscore in the gir test to trigger this.
Fixes#436
Make so both executable() targets that are marked as native and
external programs (which are usually build tools compiled for the
host machine) are not supposed to be run with the exe wrapper.
Not only does extract_all_objects() now work properly again,
extract_objects() also works if you specify a subset of sources all of
which have been compiled into a single unified object.
So, for instance, this allows you to extract all the objects
corresponding to the C sources compiled into a target consisting of
C and C++ sources.
Pre-calculate the output directory for GeneratedList and CustomTarget so
we can directly use the same code for both while compiling C/C++ files
and headers.
There is no reason to have separate branches for GeneratedList and
CustomTarget since both can be used in almost exactly the same way for
generating sources.
This is going to used next for adding generated sources support to Vala.
get_filename() made no sense for CustomTarget since it can have multiple
outputs. Also use get_outputs() for GeneratedList since it has the same
meaning and remove unused set_generated().
As a side-effect, we now install all the outputs of a CustomTarget.
This is done by adding a new compiler method called 'no_warn_args' which
returns the argument(s) required for the compiler to emit no warnings
for that compilation.
This take care of not disabling warnings for C code compiled into the
BuildTarget. Also includes tests for ensuring all this.
