This test covers the case where the resource script references a file which
is created by a custom_target (in this case, an icon).
Put icon in a separate directory to ensure we excercise setting the include
path to the directory which contains it.
On macOS, we set the install_name for built libraries to
@rpath/libfoo.dylib, and when linking to the library, we set the RPATH
to its path in the build directory. This allows all built binaries to
be run as-is from the build directory (uninstalled).
However, on install, we have to strip all the RPATHs because they
point to the build directory, and we change the install_name of all
built libraries to the absolute path to the library. This causes the
install name in binaries to be out of date.
We now change that install name to point to the absolute path to each
built library after installation.

With this, the default workflow on macOS matches what everyone seems
to do, including Autotools and CMake. The next step is providing a way
for build files to override the install_name that is used after
installation for use with, f.ex., private libraries when combined with
the install_rpath: kwarg on targets.
When we link to an external library either with find_library() without
any dirs:, or with dependency(), we should be able to run uninstalled
out of the box without having to set any environment variables or other
shenanigans.
This is especially important on macOS because only the system frameworks
directory is in the default runtime path, and all other frameworks and
libraries need to be found with RPATH or absolute path to the dylib.
This is a special type of option to be passed to most 'required' keyword
arguments. It adds a 3rd state to the traditional boolean value to cause
those methods to always return not-found even if the dependency could be
found.
Since integrators doesn't want enabled features to be a surprise there
is a global option "auto_features" to enable or disable all
automatic features.
When a test fails due to a signal (e.g., SIGSEGV) it can be somewhat
mysterious why the test failed. Also, even when a test fails due to a
non-zero exit status it would help if the exit status was reported. This
augments the result string to include the non-zero exit status or
signal number and name.
Resolves#3642
Added method concatenate_string_literals to CCompiler. Will concatenate
string literals.
Added keyword argument 'concatenate_string_literals' to Compiler.get_define.
If used will apply concatenate_string_literals to its return value.
Because vala is not listed in clike_langs, is_source(fname) is returning False
for Vala source files. Therefore, extract_all_objects() is completely empty
for Vala programs.
Fixes#791
Input files can be in any file encoding, not just utf-8 or isolatin1. Meson
should not make assumptions here and allow for the user to specify the
encoding to use.
On Windows, if we are going to link with a shared module, we need the
implib.
Use case: The Xorg server builds some X protocol extensions as modules. The
implibs for these modules need to be shipped as part of the SDK, to enable
building of 3rd party extensions which reference symbols in (and hence on
Windows, need to be linked with) these modules.
Refine #3277
According to what I read on the internet, on OSX, both MH_BUNDLE (module)
and MH_DYLIB (shared library) can be dynamically loaded using dlopen(), but
it is not possible to link against MH_BUNDLE as if they were shared
libraries.
Metion this as an issue in the documentation.
Emitting a warning, and then going on to fail during the build with
mysterious errors in symbolextractor isn't very helpful, so make attempting
this an error on OSX.
Add a test for that.

This simplifies a lot of code, and centralize "key=value" parsing in a
single place.
Unknown command line options becomes an hard error instead of
merely printing warning message. It has been warning it would become an
hard error for a while now. This has exceptions though, any
unknown option starting with "<lang>_" or "b_" are ignored because they
depend on which languages gets added and which compiler gets selected.
Also any option for unknown subproject are ignored because they depend
on which subproject actually gets built.
Also write more command line parsing tests. "19 bad command line
options" is removed because bad cmd line option became hard error and
it's covered with new tests in "30 command line".
When using binutils's windres, we can instruct it to invoke the preprocessor
in such a way that it writes a depfile, so that dependencies on #included
files are automatically tracked.
Not implemented for MSVC tools, so skip testing it in that case.
This is a simple test case, checking for installed_files.txt, which just
makes sure the syntax is accepted.
Manual tests confirmed the permissions were set correctly.
A follow up commit adds a unit test based on this directory.
Expose depend_files: from the custom_target this creates.
This is the change suggested in #2815, with tests and documentation added.
Fixes#2789 (duplicate #2830)
This checks not only for existence, but also for usability of the
header, which means it does a full compilation and not just
pre-processing or __has_include.
Fixes https://github.com/mesonbuild/meson/issues/2246
That syntax is invalid, since decimal numbers should never have a
leading zero and octal numbers use the `0o` prefix instead.
This matches Python 3 syntax which does not accept it:
$ python3
>>> 0123
File "<stdin>", line 1
0123
^
SyntaxError: invalid token
>>>
Add a "failing" test case to confirm this property is preserved and no
regressions are introduced in this area.
Simplify support for alternate bases using int(..., base=0) which
auto-detects it using the standard Python syntax for numbers.
Octal numbers are useful to specify permission bits and umasks.
Binary numbers are not super useful... But considering we get them for
free, let's allow them here too.
v2: Tweak the regex so it doesn't accept a decimal number with a leading
zero, which is invalid for int(..., base=0) and would raise a ValueError
if passed around.
This will copy the file to the build directory without trying to read
it or substitute values into it.
Also do this optimization if the configuration_data() object passed to
the `configuration:` kwarg is empty, and print a warning about it.

* mesonbuild/compilers/c.py: Make the `find_library` method more generic by allowing the user to supply the `code` for compiling and linking.
* mesonbuild/compilers/fortran.py: Use the methods inherited from `Compiler` base class where appropriate. Also reuse `CComiler` methods where applicable. This should be sufficient to get various compiler/linker arguments as well as to compile and link Fortran programs. This was tested with `gfortran` compiler, and while the other compilers ought to work for simple cases, their methods are primarily inherited from the base `FortranCompiler` class.
* test cases/fortran/10 find library/gzip.f90: Fortran module with some basic Fortran wrapper interfaces to `gzopen`, `gzwrite`, and `gzclose` C `zlib` functions.
* test cases/fortran/10 find library/main.f90: Fortran program using the `gzip` Fortran interface module to write some data to a gzip file.
* test cases/fortran/10 find library/meson.build: Meson build file for this test case. This demonstrates the ability to link the Fortran program against an external library.
For now dicts are immutable, and do not expose any methods,
they however support "native" syntax such as [] lookup,
and foreach iterating, and can be printed.
To allow the javac -implicit:class behaviour to know where to find
generated .java files then the build directory for the target is also
added to the -sourcefile path.
