Removing the existing toolchain first, or The same -prefix directory, then the build scripts may get confusedĪnd exit with a linker error complaining that hard float code can't be Hard-float toolchain and then try to build a soft-float toolchain with Troubleshooting Build Problemsīuilds work best if installing into an empty directory. The -enable-multilib flag therefore does not actually enable multilib supportįor musl libc. The musl compiler (riscv64-unknown-linux-musl-) will only be able to targetĦ4-bit systems due to limitations in the upstream musl architecture support. Using the -print-multi-lib flag on either cross-compiler. It will support the most common -march/ -mabi options, which can be seen by Riscv64-unknown-linux-gnu- but will be able to target both 32-bit and 64-bit ![]() The multilib compiler will have the prefix riscv64-unknown-elf- or Glibc-based or Linux musl libc-based cross-compiler, respectively. configure -prefix=/opt/riscv -enable-multilibĪnd then either make, make linux or make musl for the Newlib, Linux ![]()
