早上大家，林间空气引起你的注意。
我是新手，在我的全新centos-6.5主机上安装gcc-6时遇到了问题，让我发疯了。
如您所知，CentOS-6.5上的默认gcc版本是4.4.7，不支持c ++ 11，所以我尝试安装最新版本。
安装mpc-1.0.3，gmp-6.1.1，mpfr-3.1.4和isl-1.6后，安装gcc-6.2时会出错。
它显示：
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wiki页面enter link description here中所提到的，也许我应该检查一些依赖库。
然后我一遍又一遍地尝试安装旧版本的mpc，mpfr，gmp和gcc，但发生了同样的错误。
我也检查了config.log，但没有发现任何线索。
所以我在这里发布一个帖子以获得任何帮助。感谢！
对于其他可能有帮助的事情（即命令，结果和日志），发布如下：

答案 0 :(得分：4)
它已经解决了！
对于最后的尝试，我在GCC源目录中运行 ./ contrib / download_prerequisites 脚本，而不是手动下载，编译和安装依赖库，并且它成功了！
顺便说一句，在运行＆＃39; configure＆＃时，应添加选项＆＃39; -enable-language = c，c ++＆＃39; 来过滤java支持39;脚本，否则，它仍然报告错误＆＃39; libgmp.a：无法读取符号：错误值＆＃39;据说是关于java语言支持的。
感谢您的关注。
