构建libc（newlib）结果为“找不到-lc”

Question

I built a cross-compiler for sh3eb-elf targets. Now I need a libc implementation. However, when I want to build newlib , configure fails.

Running configure:

../newlib-cygwin/configure --host=sh3eb-elf

It fails. A quick look into config.log :

configure:4435: sh3eb-elf-gcc    conftest.c  >&5
[...]/sh3eb-elf/sh3eb-elf/lib/gcc/sh3eb-elf/8.1.0/../../../../sh3eb-elf/bin/ld: cannot find -lc
collect2: error: ld returned 1 exit status
configure:4439: $? = 1

Obviously the linker does not find libc which is what I am trying to build here in the first place. I am confused... Are the parameters of configure wrong?

Answer 1

我不确定为什么，但是正如Chrono Kitsune指出的那样，使用--target=sh3eb-elf可以解决问题。
