We have used musl 1.1.16, i.e the latest version. Here are the failures that we see: - On SuperH: usr/sh4-buildroot-linux-musl/sysroot/usr/include/asm/ptrace_32.h:44:8: error: redefinition of 'struct pt_regs' - On PowerPC64 and PowerPC64le: usr/powerpc64-buildroot-linux-musl/sysroot/usr/include/asm/ptrace.h:31:8: error: redefinition of 'struct pt_regs' usr/powerpc64le-buildroot-linux-musl/sysroot/usr/include/asm/ptrace.h:31:8: error: redefinition of 'struct pt_regs' - On PowerPC: usr/powerpc-buildroot-linux-musl/sysroot/usr/include/asm/ptrace.h:31:8: error: redefinition of 'struct pt_regs' - On Microblaze, little endian and big endian usr/microblaze-buildroot-linux-musl/sysroot/usr/include/sys/procfs.h:30:2: error: unknown type name 'elf_gregset_t' error: 'Elf64_auxv_t' undeclared (first use in this function) error: 'Elf32_auxv_t' undeclared (first use in this function) ... On all those architectures, gdbserver builds fine with other C libraries. I had a brief look at the commits in musl since 1.1.16 and couldn't spot anything that looked related. Are you interested in fixing those issues? If needed, I can provide an easy way of reproducing those build failures. Thanks!
