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
There is basically no such word in english, "nonexistant".
American people use "nonexistent" and British people used
to have "non-existent", but some time ago they did away with
the hyphens, so there is only one option really: "nonexistent".

Everywhere we use this object, we end up iterating over it and comparing
compiler.get_language() with something. Using a dict is the obvious
choice and simplifies a lot of code.
Check if the compiler prefixes an underscore to global symbols. This is
useful when linking to compiled assembly code, or other code that does
not have its C symbol mangling handled transparently by the compiler.
C symbol mangling is platform and architecture dependent, and a helper
function is needed to detect it. Eg: Windows 32-bit prefixes underscore,
but 64-bit does not. Linux does not prefix an underscore but OS X does.
Instead of adding it everywhere manually, create a wrapper called
mesonlib.Popen_safe and use that everywhere that we call an executable
and extract its output.
This will also allow us to tweak it to do more/different things if
needed for some locales and/or systems.
Closes#1079
Using 'mesonbuild' as the module can cause it to use the
system-installed module and can also break if we rename the directory,
so avoid that by always using relative imports.
This is already how it should've been, but:
a) The test for this was wrong since Dependency is a base class for all
dependencies and isinstance on an InternalDependency will also be true
b) Internal dependencies can't ever be used here anyway because compiler
checks are always run at configure time and internal dependencies are
only built after that.
Also did a bit of cleanup.
interpreter.py: There’s a catch all except clause at the line 1928, it didn’t give the user any information whatsoever about the exception it caught. Now it at least print it to the log as a warning.
Sometimes we want to restrict the acceptable versions to a list of
versions, or a smallest-version + largest-version, or both. For
instance, GStreamer's opencv plugin is only compatible with
3.1.0 >= opencv >= 2.3.0
Move CCompiler.compile to Compiler.compile so that ValaCompiler can use
it. Also rewrite ValaCompiler.sanity_check to use it since it does
a simple compile check.
At the same time, it enhances ExternalLibrary to support arguments for
languages other than C-like.
Includes a test for this that links against zlib through Vala.
Closes#983
* contributing: Use should instead of thould
* interpreter: Use exist_ok parameter in subdir function
We explicitly depend on python 3.4 or newer, which means the exist_ok
parameter is available. Use it instead of a try with a pass on except.
* authors: Add my name at the end of authors file
This is the common Python convention for private methods
so lets not expose these to build files as they are
implementation details and their behavior is undefined.
All assignments in meson should be by value, so mutable objects
(i.e. environment() and configuration_data()) should be copied
automatically on assignment.
Fixes#831.
We should only silently return from a dependency() call if the error is
transient (old version, wrap failed to download etc), not if the
subproject invocation or dependency name are incorrect.
For instance, if you use a dependency(..., fallback : ...) call in
a meson.build not in the root directory, we would always ignore the
call instead of erroring out due to invalid usage.
We should consider categorising our exceptions in this manner elsewhere
too.
If first checking for a dependency as not-required, and then later
checking for the same dependency again as required, we would not
error out saying the dependency is missing, but just silently
re-use the cached dependency object from the first check and then
likely fail at build time if the dependency is not actually there.
With test case.
Fixes#964.
Seems better to do this since the behaviour is compiler-specific. Would
be easier to extend this later too in case we want to do more
compiler-specific things.
The error message is misleading (talks about external dependencies), and
doesn't tell you what you need to do (use the output of
declare_dependency, dependency, or find_library). At the same time
rename add_external_deps to add_deps since it adds internal deps too.
Plus many more error message improvements all over the place.
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.
