最近搞坏了ubuntu，大半夜装好公司的电脑-limint系统，第二天早晨编译 ./configure出错configure: error: C compiler cannot create executables
很是无语呀，找了很多解决办法：
1，
Having a compiler (like gcc) is not enough to compile C programs, you also need a C library. If it is missing, you will experience the (somewhat obscure) error message:
configure: error: C compiler cannot create executables
You may fix this by installing libc6-dev and linux-libc-dev packages. After you install them, simply rerun ./configure.
没有效果！
2，
You can test this by compiling a small C example with the -m32 flag.
// Minimal C example
#include <stdio.h>
int main()
{
printf("This works
");
return 0;
}
Compiling:
gcc -m32 -o m32test m32test.c
确实也没有通过！

Logs don't lie! configure.log is what i need to get to the root of the problem. The issue is this:
gcc checking whether the C compiler works... no
The simple answer to this is just
sudo apt-get install clang && rvm install 1.9.3 --with-gcc=clang
这是解释：ask：it would be interesting to know why GCC didn't work
answer：GCC doesn't work for me either. Clang works though.
这个方法好使！
另外还有一个方法没有试试：
ln -s /usr/bin/gcc /usr/bin/gcc-apple-4.2
