[Discussion] Would it be feasible to port this for other libc implementations/generalize?

[Haringat]

I have tried to dig into the source code but sadly, my Makefile knowledge did not suffice to actually understand most of it.

But I wondered how heavily is this geared towards musl? Would it be possible/feasible to replace musl with another libc implementation to build other toolchains?

this repo is owned by the maintainer of musl libc. if you're looking for something more general with multiple libc/compiler/etc. support, there are other choices.

• buildroot : https://buildroot.org/
• openembedded / yocto : https://www.openembedded.org/wiki/Main_Page and https://www.yoctoproject.org/

these are both geared towards generating full OS deployments/system images, with buildroot being easy to get started with and yocto being the ahh let's say "most enterprise ready." but the compilers from either should be generally usable.

Thanks. I am not really looking into building my own OS. What I am going for is creating docker images with cross-compilers.

the approach used here is fairly generic.i basically copied it in shell-form in the mingw recipe in sabotage linux. this spared me from having to install stuff during the build of the single components.

[Haringat]

Okay, thanks. Then I will try it again and see what I can come up with.

As an aside, Debian provides cross-compilers for systems the project supports.
