🐚 Add -static flag to musl-gcc (and clang)

When you configure musl with -disable-shared, there is no libc.so to link. So you must compile or rather link with -static. And not adding -static doesn't make sense. The musl C compiler musl-gcc, which is basically just a wrapper around gcc doesn't set that by default.

This little script rectifies the situation. It checks, if the shared library libc ios available, and if not, forces the -static flag.

Install where musl-gcc resides and use with CC=gcc.musl.

For cmake you also need to define CMAKE_SKIP_RPATH. This is helpfully done in the definition provided and installed by mulle-musl-cc.

To reap the fruits of this definition, set SDKs to "musl" with mulle-sde env --global set SDKS musl,

** DOES NOT WORK ON MacOS or Windows **

All compilers define __MULLE_MUSL__ and define __MULLE_STATICALLY_LINKED__, if appropriate.

mulle-clang support

There is also clang.musl and mulle-clang.musl. These files attempt to do what musl-gcc does, but for the clang compiler. But they always force static compilation and linking, whereas gcc.musl will also work with shared library musl.

Add mulle-musl-cc to your mulle-sde project

mulle-sde add --marks no-header,no-link --github mulle-cc mulle-musl-cc

Note

This project does not build the mulle-musl library. See mulle-musl for that.
