每个人每天都在为你的注意力而战。
我是一个新手，并且在我的全新的centos-6.5主机上安装gcc-6时遇到了问题，这让我疯了。
如你所知，CentOS-6.5上的默认gcc版本是4.4.7，不支持c ++ 11，所以我试着安装最新版本。
安装mpc-1.0.3，gmp-6.1.1，mpfr-3.1.4和isl-1.6后，安装gcc-6.2时出现错误。
表明：
checking for suffix of object files... configure: error: in `/root/Downloads/objdir-gcc-6.2.0/x86_64-pc-linux-gnu/libgcc': configure: error: cannot compute suffix of object files: cannot compile See `config.log' for more details. make[2]: *** [configure-stage1-target-libgcc] Error 1 make[2]: Leaving directory `/root/Downloads/objdir-gcc-6.2.0' make[1]: *** [stage1-bubble] Error 2 make[1]: Leaving directory `/root/Downloads/objdir-gcc-6.2.0' make: *** [all] Error 2 正如在这个维基页面， 在这里input链接描述 ，也许我应该检查一些依赖的库。
然后我试着重复安装mpc，mpfr，gmp和gcc的老版本，但是同样的错误发生了。
我也检查了config.log，但没有find线索。
所以我在这里发布一个线索的任何帮助。 感谢！
对于其他的东西（即命令，结果和日志）可以帮助发布如下：

它解决了！
对于最后的尝试，我运行了GCC源代码目录下的./contrib/download_prerequisites脚本，而不是手动下载，编译和安装依赖的库，并且成功了！
顺便说一下，在运行'configure'脚本时，应该添加选项'-enable-language = c，c ++'来过滤java支持，否则它会报错'libgmp.a：could not read symbols：Bad价值“这是据说是关于Java语言支持。
感谢关注。
