It's fairly common on Linux and *BSD platforms to check for these
attributes existence, so it makes sense to me to have this checking
build into meson itself. Autotools also has a builtin for handling
these, and by building them in we can short circuit cases that we know
that these don't exist (MSVC).
Additionally this adds support for two common MSVC __declspec
attributes, dllimport and dllexport. This implements the declspec
version (even though GCC has an __attribute__ version that both it and
clang support), since GCC and Clang support the MSVC version as well.
Thus it seems reasonable to assume that most projects will use the
__declspec version over teh __attribute__ version.
Fixes:
meson.build:6:0: ERROR: Uncomparable version string 'unknown'.
This was previously partially fixed in a8694f4b, which only fixed it
for cached fallback dependencies.
This makes any warning message printed by meson raise an exception,
intended to be used by CI and developpers to easily catch deprecation
warnings and other potential issues.
Somehow I overlooked this class when adjusting everything else in c59ec874
et seq.
Update Python3Dependency so it has a _factory() method which returns a list
of constructors, depending on the method: kwarg, which integrates better
with the reporting in find_external_dependency()
This ensures the return of a PkgConfigDependency object, if the dependency
is found with pkgconfig, so we don't have to specifically implement
get_pkgconfig_variable() ourselves.
With this it is now possible to do
foobar = executable('foobar', ...)
meson.override_find_program('foobar', foobar)
Which is convenient for a project like protobuf which produces both a
dependency and a tool. If protobuf is updated to use
override_find_program, it can be used as
protobuf_dep = dependency('protobuf', version : '>=3.3.1',
fallback : ['protobuf', 'protobuf_dep'])
protoc_prog = find_program('protoc')
Otherwise, git fiddles with the cmd.exe console's color behaviour and
disables it, which causes it to stop interpreting ANSI color codes
outputted by meson for colored output.
Effectively, as soon as any subproject is initialized, cmd.exe goes
nice coloured output to ugly raw ANSI codes.
The regression was introduced in my recent refactoring of
that method (8377ea4).
This commit simply restores the ordering of the generated
scan_command, ensuring `-lasan` and other internal linker
flags come before `--library` or `--program`
We now use the soversion to set compatibility_version and
current_version by default. This is the only sane thing we can do by
default because of the restrictions on the values that can be used for
compatibility and current version.
Users can override this value with the `darwin_versions:` kwarg, which
can be a single value or a two-element list of values. The first one
is the compatibility version and the second is the current version.

fixes#4032: meson now checks properly for the compiler used to compile dub dependencies
fixes#3568: applied the following patch https://paste.debian.net/1039317/
meson now adds flags for native dependencies required by dub modules
meson now checks for the D version implemented by the compiler used to build dub dependencies (execpt gdc which doesn't support this)
* The current version matching logic is brittle
with respect to Clang. LLVM and Apple Clang use
slightly different but nowadays overlapping
version ranges. Instead, we now just check whether
the compiler supports the given `-std=` variant
and try its respective fallback instead of
testing version ranges.
* Currently, RPATHs coming from dependencies and
`build_rpath` provided by the user might contain
the same path. Apple's `install_name` tool is
allergic to providing the same argument twice
when removing RPATHs:
error: install_name_tool: "-delete_rpath /usr/lib" specified more than once
Treat it the same as -lfoo by deduping and adding to --start/end-group

We don't do any advanced transformation for MSVC or de-dup because
this is a very rare syntax.
Allowing to use the new "feature" option type and allowing not to fail
on subproject if it is not necessary to fail.
By default subprojects are "required" so previous behaviour is not
changed.
Fixes#3880
At the moment, this check only exists for pkg-config dependencies (and dub,
where the code is cut-and-pasted)
Factor it out and apply it to all dependency type
