See full list on wiki. Making this work has been on the long-term agenda for a long time, but not a priority; if you can, it's much better to rebuild When building musl, you will also need a C99 compiler with support for gcc-style __asm__ statements and assembly source files, and weak symbol support in the linker.

Contribute to musl-cross/musl-cross development by creating an account on GitHub. statfs/statvfs ABI issues have been fixed, along with a number of small header file errors. Clang (>=3. The "musl" part of the target is important: the binaries will ONLY run on a musl-based system, like Alpine. For example x86_64-linux-musl-cc will compile C code to run on musl Linux amd64. It is lightweight, fast, simple, free, and strives to be correct in the sense of standards conformance and safety. To start using musl, you have three choices. GCC is officially supported using the musl-gcc wrapper or the musl-cross project (for details see Getting started). For more advanced usage involving libraries or C++, though, a dedicated cross toolchain or building in a musl-based musl-cross provides prebuilt cross-compiler toolchains and cross-compiler build instructions. musl. The multilib compiler will have the prefix riscv64-unknown-elf- or riscv64-unknown-linux-gnu- but will be able to target both 32-bit and 64-bit systems.
