Multiarch CI jobs fail

[nickva]

Noticed recently most of the multi-arch CI jobs fail

It seems $platform/$image syntax is not support any longer by runner.

docker run --rm --interactive --mount type=bind,source=$(pwd),target=/host arm32v6/alpine

[bellard]

Thank you. It would be good to add the following targets:

• x86 32 bit build on debian:

make CONFIG_M32=y

• Windows 64 bit cross build using mingw on debian. At least some tests may be run with wine:

make CONFIG_WIN32=y

• if possible, cosmopolitan build by downloading the cosmocc compiler.

Linux 32 bit and Cosmopolitan: #392

For 32bit linux it was easier to go with Ubuntu rather than Debian, as it's a directly supported OS for a Github Actions. Installing gcc-multiib package seems to worked to allow compiling with -m32.

[nickva]

Cross compiling on Ubuntu with CONFIG_WIN32=y fails when trying to link to pthreads.

Tested on Ubuntu 24 host and sudo apt install mingw-w64.

$ make CONFIG_WIN32=y

I can see winpthreads is installed but it may need either a linker flag to make it link staticly?

/usr/i686-w64-mingw32/lib $ ls *winpthread*
libwinpthread-1.dll  libwinpthread.a  libwinpthread.dll.a

There is a windows runner for Github Actions, that could be an option if compiling with Msys2?

[nickva]

I managed to compile with mingw64 with this patch:

If static option is not provided then need to put libwinpthread-1.dll somewhere to be found at runtime.

I wonder is the intent that workers/atomics or anything related to pthreads should work for windows? If not, perhaps we can exclude it with an #ifdef section, then the linker won't look for it at all.

A while back I created a PR to add such a mode #300, as we at Apache CouchDB don't use workers and didn't want to include the winpthreads.dll in the distribution, but now I wonder if perhaps pthreads were never intended to work on Windows all.

[bellard]

Regarding -lpthread, your patch is not needed. You need instead to copy libwinpthread*.dll to the same directory as qjs.exe (see how the Windows binary packages are built in the win_binary target of the "release.sh" script).

I confirm workers are not supported with Windows. #ifdef can be added in the Makefile.

[nickva]

I added CONFIG_LTO=y, mingw cross-compile and a windows msys2 target

[nickva]

@bellard I think #393 is ready for another look
