gmp4.3.2 安装 configure: error: could not find a working compiler
今天在虚拟机上想安装gcc4.7.2
但貌似有三个依赖。
那就顺序装吧。
装到gmp的时候。怎么都configure不过去，各种查各种不行，但是我之前在别的机器装成功过。
刚开始一直以为是某个编译程序没有装，后来仔细对比了通过的和不通过的。发现问题所在了。
如下：
这个是错误的。

由于另一个机器无法拷贝。我就把这个机器之后编译好的拿过来吧。

就贴这么几行，大家注意找不同点。
其实就出在ABI=64和ABI=32上面了。
ABI是什么呢？
百度一下：
应用程序二进制接口
ABI:application binary interface
详细内容请自行百度
除了这个，大家请看前两行
pentiumm-unknown-linux-gnu
这个机器是奔腾M的处理器，所以编译器默认他是32位的处理器，而对ABI设置成了32位，编译的时候也使用的是32位。
所以config.log里就出现了icc command not found
因为貌似icc是32位编译用的。（我猜的，没有仔细考证）
那知道愿意了问题就好解决了。
./configure --prefix=/usr/local/gcc/gmp-4.3.2 --build=x86_64-linux
加上--build=x86_64-linux
注意之后编译的log前两行
checking build system type... x86_64-pc-linux-gnu
这样就成功了。
