musl-riscv-toolchain-7.1.0-2

Building

To build gcc 7.1 musl libc toolchains for riscv32, riscv64, i386 and x86_64:

for i in rv32 rv64 x86_64 i386 ; do sh bootstrap.sh $i ; rm -fr build stamps ; done

Archives

The script downloads source dependencies from the upstream sites however it is possible to short circuit this process by creating an archives subdirectory and pre-populating it with the tarballs attached to this release before running the bootstrap.sh script.

This table shows the SHA-256 digests of the source archives:

Notes

• when linking dynamic executables use the -dynamic-linker linker option to set the program interpreter e.g.-Wl,-dynamic-linker,/lib/ld-musl-riscv64.so.1
