help required - crosscompiling to armhf from arm64 #983

Closed neofeo closed 1 year ago

neofeo commented 1 year ago

HI, I am trying to crosscompile this project like this

ARCH=armhf CC=/usr/bin/arm-linux-gnueabihf-gcc CXX=/usr/bin/arm-linux-gnueabihf-g++ PKG_CONFIG_PATH=/usr/lib/arm-linux-gnueabihf/pkgconfig  meson build32  --libdir armhf  -Dwith_wayland=enabled -Dwith_xnvctrl=disabled

it does compile, but its linking everything to arm64 and bc of that fails at the end. How the hell I need to do to force it to look to armhf libraries instead?

Does it help to use meson cross file? https://mesonbuild.com/Cross-compilation.html

is stills tries to link with arm64 libs...

Ahh, maybe pkg config has to be addresed differently. Hopefully you can give me a hint.

flightlessmango commented 1 year ago

I don't think you can use the normal pkg-config, it would need to be the one for the architecture you want to compile

neofeo commented 1 year ago

even with armhf pkgconfig it doesnt work. super difficult to setup it seems. sadly, there is no deb i can found with wayland enabled. debian repo and ubuntu repo do not work

neofeo commented 1 year ago

/usr/bin/arm-linux-gnueabihf-pkg-config --variable pc_path pkg-config outputs /usr/local/lib/aarch64-linux-gnu/pkgconfig:/usr/local/lib/pkgconfig:/usr/local/share/pkgconfig:/usr/lib/aarch64-linux-gnu/pkgconfig:/usr/lib/pkgconfig:/usr/share/pkgconfig super wrong then, it doesnt find any armhf package required for mangohud, I am unable to export the right path, but even then , armhf pkgconfig at /usr/lib/arm.../pkgconfig/ doesnt have the client wayland .pc

super confusing. there is any repo with armhf builds with wayland enable you can recommend?

neofeo commented 1 year ago

Ok,I made some horriblr hacks that eventually make it to work. Not proud, but enough:)
