Hello.

How can I add custom flags to my build ?

I tried setting CXXFLAGS/LDFLAGS/CFLAGS without luck:

CXXFLAGS="-fno-lto" ${_arch}-meson

xan.

That's similar to qmake. But you can still at least insert the flags at build time of the mingw-w64-mesion package instead of duplicating them. I did the same for mingw-w64-qt5-base: https://github.com/Martchus/PKGBUILDs/commit/6face8aef30195f0800623e38e60c460c3db0876

This way we can change flags when needed by only customizing mingw-w64-environment and just need to rebuild mingw-w64-meson (and mingw-w64-qt5-base).

ok; seems their design allow to have rules for native and cross targets in the same build, no idea what it's for

@xantares, I don't think that this work for meson, from the docs:

https://mesonbuild.com/Builtin-options.html

c_args, cpp_args, c_link_args, and cpp_link_args only affect native builds, when cross compiling they will not be applied to binaries or libraries targeting the host system, only those being run on the build system.

I just did a quick test adding -v to ninja for mingw-w64-libsoup, current meson wrapper:

meson wrapper modified as you suggest:

hello, can you use mingw-w64-environment ?

just do "source mingw-env @TRIPLE@" at beginning of meson-mingw-wrapper instead of setting all the flags manually, see /usr/bin/mingw-env.sh

xan.

one last thing, can you add the "-Wl,-O1,--sort-common,--as-needed" linker flags that are used in mingw-w64-configure and mingw-w64-cmake ?

thanks!

can you add mingw-w64-cmake as optdepends ?

could you add the cmake entry in toolchain-mingw.meson under [binaries] ?

cmake = '@TRIPLE@-cmake'

then mingw-w64-cmake can be added to optdepends

this is needed for mingw-w64-mesa if I want to switch to meson

Please add c_link_args = ['-fstack-protector'] and cpp_link_args = ['-fstack-protector'] under [properties] or some package will not build.
