Need to pass -fpermissive to force C++ compilers to only warn about our
non-conformant code that tests for a symbol being defined.
Also do a simple #ifdef check first in has_header_symbol to allow
arbitrary macros to be detected which would not have been detected
earlier. This follows what AC_CHECK_DECL does.
Closes#958
* 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.
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.
Not all headers are public, or contain public types. GTK-Doc allows
adding headers to be ignored during the "scan" phase, by passing the
`--ignore-headers` command line argument to gtkdoc-scan.
Currently, you can do something like:
ignored_headers = [ 'foo-private.h', 'bar-private.h', ]
gnome.gtkdoc(...
scan_args: [
'--ignore-headers=' + ' '.join(ignored_headers),
],
...)
But it does not guarantee escaping rules and it's definitely not nice.
We can add a simpler version of that mechanism through a new positional
argument, `ignore_headers`, which behaves like `content_files` or
`html_assets`, and takes an array of header files to ignore:
gnome.gtkdoc(...
ignore_headers: ignored_headers,
...)
If a `<modulename>-overrides.txt` file exists in the docs directory it
means it's intended to be used in place of the one gtk-doc generates.
GLib and GTK+, for instance, ship with one because some of the types
they provide — like the thread primitives, or the platform macros —
contain architecture-dependent fields that should not be accessed
directly.
This commit should close the last bit of issue #550.
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.
Every other build system does this, and at least OS X, iOS, and Android
depend on this to select the OS versions that your application is
targetting.
At the same time, just use a wrapper for self.run and self.links to
share the common (identical) code.
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.
Simply placing a reference to it isn't enough for the linker to try and
think it's being used and do a symbol availability check with
-Wl,-no_weak_imports on OS X ld.
Specifically, wherever we have sources or outputs, we want to use an
OrderedDict so that the build is always deterministic. It was reported
by Olexa Bilaniuk that `ar D` creates static libraries with different
checksums depending on the order of the object files.
See: https://github.com/mesonbuild/meson/pull/951
We don't actually want to preserve the order in which they are listed.
We just want the order to be deterministic and predictable.
This is needed to ensure that symbol availability checks actually fail
at link time (instead of at runtime) which is necessary for has_function
to work correctly.
