Details
Description:
RISCV64 requires libatomic for pthreads, but this lib is not provided by the current RISCV compiler packages. So all programs that require -pthread fail to link. For at least some programs, replacing -pthread with -lpthread seems to be sufficient. Additional info: * riscv64-linux-gnu-gcc 8.2.0-1 * riscv64-linux-gnu-binutils 2.31.1-1 * riscv64-linux-gnu-glibc 2.27-1 * riscv64-linux-gnu-linux-api-headers 4.16-1 Steps to reproduce: $ echo "int main() {}" > main.c $ riscv64-linux-gnu-gcc -pthread empty.c /usr/lib/gcc/riscv64-linux-gnu/8.2.0/../../../../riscv64-linux-gnu/bin/ld: cannot find -latomic collect2: error: ld returned 1 exit status |
