It is extremely common to need to know within a given dependency if
a given header, symbol, member, function, etc exists that cannot be
determined from the version number alone.
Without passing dependency objects to the various compiler/linker
checks and with many libraries headers/libraries being located in
their own subdirs of the standard prefix, the check for the library
would not find the header/function/symbol/etc.
This commit allows passing dependency objects to the compiler checks so
that the test program can be compiled/linked/run with the necessary
compilation and/or linking flags for that library.
Add support for passing a description to configuration data
setter methods via a 'description' kwarg. The description
string will be used when meson generates the entire configure
file without a template, autoconf-style.
These paths are now generated similar to
NinjaBackend.generate_single_compile where IncludeDirs create includes
of both the build directory path and the source directory path.
This also fixes a bug with include_directories, where the path string
supplied to the IncludeDirs initializer was used for the search path,
instead of the actual location to which it referred. Often, this was a
'.', and not a really useful path.
Having support for the '%' operator makes it easier to implement
even/odd version checks, like:
enable_debug = get_option('enable-debug')
if enable_debug == 'auto'
if minor_version % 2 == 0
enable_debug = 'minimum'
else
enable_debug = 'yes'
endif
endif
which would be impossible without resorting to less obvious long-hand
forms like:
a - (b * (a / b))
Passing an absolute path to `install_dir` would previously always
attempt to install there, instead of obeying DESTDIR, since os.path.join
will 'reset' on absolute paths.
* Add a new compiler object method: has_members
Identical to 'cc.has_member', except that this takes multiple members
and all of them must exist else it returns false.
This is useful when you want to verify that a structure has all of
a given set of fields. Individually checking each member is horrifying.
* Fix typo in exceptions for has_member(s)
For commands that always output to stdout and don't have a "-o" or
"--output" or some other similar option, this 'capture' setting allows
the build to capture the result and place it in the output file.
