如題所示，我在minix3中直接安裝了clang，然後使用如下指令編譯c程式報錯。
# clang hello.c -o hello
clang: error: unable to execute command: Executable "ld" doesn't exist!
clang: error: linker command failed with exit code 1 (use -v to see invocation)
#
提示說缺少ld，其實需要安裝binutils這個工具，可以通過pkgin_cd in binutils：
# pkgin_cd in binutils
Checking for CD in /dev/c0d2p2.
/dev/c0d2p2 is mounted on /mnt
Found.

這時候系統中就有了ld指令了。
再次編譯，順利通過。
其實，這個問題一般不會出現，是我自己少安裝了binutils，直接安裝了clang，不知道有沒有遇到同樣問題的同學。
