Static cross and native musl-based toolchains

This is great. Another handy musl-based toolchain that supports some of these targets is ellcc [1]. It's llvm+clang based. It's a little behind so I suppose it doesn't support RISCV yet. It will probably never support SH targets because those aren't in llvm and there aren't any public plans to add one AFAIK. [1] http://ellcc.org/ http://ellcc.org/

If I understand this correctly, since MUSL's USP is static linking of musl-libc thereby removing any dependency on breaking changes in glibc, we now have the ability to build with the exact same compiler and generate stand-alone binaries without a libc dependency on Windows, Mac, Linux, across multiple processors (x86, x64, ARM, ARM-64, ...). This is fantastic news!

Since we're talking musl, the author of the library has recently asked[1] the community to support him more actively on Patreon[2].

I’m using musl to cross-compile static Windows binaries from Mac for my app [0]. Here’s the instructions I use for it: https://blog.filippo.io/easy-windows-and-linux-cross-compilers-for-macos/ https://blog.filippo.io/easy-windows-and-linux-cross-compile... I’ve been using this in real world production builds and I’ve had no issues so far, I compile SQLite with it as it’s my main C dependency. No slowdowns, nothing weird happening, it just works like a champ. Very impressive. [0] (Obvious disclosure, I’m the developer) https://getaether.net https://getaether.net

  correct me if I'm wrong: mingw-w64 has nothing to do with musl libc, which is exclusively for Linux

    Ah - the article explains how to cross compile via musl. The article mentions doing it for Linux, I am using a similar process for Windows. The article also recommends mingw for Windows, but that is unrelated.

  This is great! Thank you for the work and information on how to use it. Have you been able to get musl-libc to compile on and for Mac OSX/iOS, along with a supported musl-gcc-wrapper? The thought of a completely statically linked, self contained binary/library for Mac/iOS is salivating

    No unfortunately, I’ve not needed that, since my native development environment is Mac and I need cross compile the other way round. I don’t see why it should not work theoretically, but my interpretation is that Apple’s licenses for Cocoa / iOS do not allow that.
