Does Avalonia need to adapt to MIPS architecture?

It needs .NET Core Runtime support MIPS architecture first.

Should work with Mono runtime, but you'll also have to build libSkiaSharp.so

Hi @kekekeks

libSkiaSharp.so is https://github.com/mono/SkiaSharp ?

Thanks,

@xiangzhai yes, you'll need to make Skia/SkiaSharp to compile to MIPS platform.

Hi @jmacato

Thanks for your response!

I am on it.

Hi @jinyuttt

It is easy to cross compile libSkiaSharp and libHarfBuzzSharp v2.80.1 for MIPS64:

./bin/gn gen 'out/linux/x64' --args='
    cc="mips64el-linux-gnuabi64-gcc"
    cxx="mips64el-linux-gnuabi64-g++"
    is_official_build=true skia_enable_tools=false
    target_os="linux" target_cpu="mips64"
    visibility_hidden=false
    skia_use_icu=false skia_use_sfntly=false skia_use_piex=true
    skia_use_system_expat=false skia_use_system_freetype2=false skia_use_system_libjpeg_turbo=false skia_use_system_libpng=false skia_use_system_libwebp=false skia_use_system_zlib=false
    skia_enable_gpu=true
    extra_cflags=[ "-DSKIA_C_DLL", "-w", "-DXML_POOR_ENTROPY" ]
    extra_ldflags=[ "--sysroot=/chroots/mips64el_stretch" ]
    linux_soname_version="80.1.0"'


depot_tools/ninja 'SkiaSharp' -C 'out/linux/x64'
depot_tools/ninja 'HarfBuzzSharp' -C 'out/linux/x64'

Then there are libSkiaSharp and libHarfBuzzSharp:

$ file out/linux/x64/libSkiaSharp.so.80.1.0 
out/linux/x64/libSkiaSharp.so.80.1.0: ELF 64-bit LSB shared object, MIPS, MIPS64 rel2 version 1 (SYSV), dynamically linked, BuildID[sha1]=79cef834fd1a2da0230545626908bad3ab5f64d7, with debug_info, not stripped

$ file out/linux/x64/libHarfBuzzSharp.so.80.1.0 
out/linux/x64/libHarfBuzzSharp.so.80.1.0: ELF 64-bit LSB shared object, MIPS, MIPS64 rel2 version 1 (SYSV), dynamically linked, BuildID[sha1]=adf3edfa4745b6e60552f2607e03846ebdadcaa4, stripped

Please read the cross-building document about generating an mips64el rootfs.

Or just use docker image aoqi/dotnet-buildtools:x86_64-ubuntu-16.04-c103199-20180628134544-upstream-cross-mips64el there is /crossrootfs/mips64el in it by following linux-instructions document.

You need harfbuzz 2.6.1. Build script is here https://github.com/mono/SkiaSharp/blob/be889396a5b8455cf52f0c00859c31c4bd5dac77/native/linux/build.cake#L94

I also have docker containers for cross compiling. Right now it is just for arm, but you might just be able to pass in the mips values to the docker build

I see I was downloading the gcc tool chain from arm, so that might need a new place.

Does clang support cross compiling to mips? I am doing this for arm

Hi @mattleibow

Does clang support cross compiling to mips?

Yes! CoreCLR MIPS64 porting is using clang https://github.com/gsvm/coreclr/blob/mips64-port/Documentation/building/linux-instructions.md#docker-images

Thanks for your advice! visibility_hidden=false is the root cause.

@xiangzhai kind of a offtopic question: does your CoreCLR port of MIPS will support SGI Octane (it's MIPS IV iirc) or only the latest MIPS32/64 ones?

@xiangzhai

Hi @jmacato

does your CoreCLR port of MIPS will support SGI Octane?

Nope!

But we open source MIPS64 (mips64r2) porting. It is easy to port to MIPS O32/N32 ABI.

Thanks,
