rvld
English | 中文版
rvld is a minimal linker implementation for the RV64GC architecture, mainly for educational purposes. rvld mostly copied the source code of rui314/mold, so it is a derivative work of mold, and is also distributed under the GNU AGPL v3 LICENSE.
rvld can statically link a simple C program (such as the Hello world in the example below) and produce a runnable binary.
cat <<EOF | $CC -o a.o -c -xc -static -
#include <stdio.h>
int main() {
printf("Hello, World.\n");
return 0;
}
EOF
$CC -B. -s -static a.o -o out
qemu-riscv64 out
# Hello, World.rvld is only about 3000 lines of Go code and has no external dependencies other than the standard library. Based on this project, PLCT Lab launched an open course "Implementing a Linker from Scratch". The course is in Chinese.
