GCC编译器升级./configure报错“configure: error: Unable to find a usable ISL.”解决办法

现象：

GCC编译器升级时，./configure报错“configure: error: Unable to find a usable ISL. See config.log for details.”

 配置好isl后，再报错“configure: error: Unable to find a usable CLooG.  See config.log for details.”

解决办法：

  （1）下载isl和cloog，编译安装。

     下载链接：ftp://gcc.gnu.org/pub/gcc/infrastructure/      

  （2）GCC ./configure配置时，加上–with-isl-include=/usr/local/include/isl/ –with-isl-lib=/usr/local/lib/  –with-cloog-include=/usr/local/include/cloog/ –with-cloog-lib=/usr/local/lib/

        再添加–with-cloog-include=/usr/local/include/cloog/ –with-cloog-lib=/usr/local/lib/后再报错找不到isl，可再重新安装isl和再执行gcc 配置。
