This doesn't seem to be a gcc problem, but > rather a build problem on your side. I have successfully built that by fixing problems by myself for both x86_64-linux-gnu and aarch64-linux-gnu. While on riscv, it fails at the configure for glibc since the compiler encounters ICE. Here is the proof https://gcc.gnu.org/pipermail/libstdc++/2020-October/051219.html https://github.com/riscv/riscv-gnu-toolchain/issues/523#issuecomment-711457612 And this is my detailed building process. https://github.com/expnkx/GCC-cross-compilation-scripts/blob/master/windows%20hosted/aarch64-linux-gnu.txt
