The problem is:

../src/vga.c:31:10: fatal error: sys/io.h: No such file or directory

compilation terminated. 

so that libvga.so did not finished compilation.

But the build script continues to build and link which causes this problem.

Still did not find a method to fix it as there is no /usr/include/sys/io.h for riscv64.
