我正在尝试在我也有权访问的服务器上的主目录中安装新的 gcc 版本（g++ 版本）。该服务器已经在其他地方有 gcc （和 gmp 等），但版本较旧，我想本地安装新的。
我跟着本指南严格来说，在我的主目录中工作。总之，我下载了新的 tars（gcc、gmp、mpfr、mpc），将它们解压并将 gmp、mpfr、mpc 移动到 gcc 的源目录中（确保它们随后被命名为gmp, mpfr, mpc）。然后我cd ..退出源代码，然后进入构建目录（objdir），然后从那里运行配置。配置进行得很好，但“make”最终返回：
checking for MPFR... yes
checking for recent GMP... yes
checking for recent MPFR... no
configure: error: MPFR version >= 2.4.2 required
make[2]: *** [configure-stage1-mpc] Error 1
make[2]: Leaving directory `/home/myusername/gcc-temp/objdir'
make[1]: *** [stage1-bubble] Error 2
make[1]: Leaving directory `/home/myusername/gcc-temp/objdir'
make: *** [all] Error 2
真的必须是2.4.2版本吗？这是问题所在吗？
事实上 gcc 等已经安装在其他地方把事情弄乱了吗？我已经设置了一些东西，比如LD_LIBRARY_PATH=""试图阻止它寻找其他地方，但无济于事。我本以为它会很高兴地使用 gcc 源目录中的 mpfr，因为使用那里的 gmp 似乎没问题。

如果configure说“需要 MPFR >= 2.4.2”，则可能有充分的理由。我不确定 GCC 的构建系统是否可以在尝试链接库之前编译这些库。传统的做法是：
构建所需的库并将它们安装到您的主目录或其子目录中，例如
$HOME/tools（这通常通过设置脚本选项来实现--prefix） -在目标目录下创建、、/和configure树。binincludeliblib64share--with-mpfr=$HOME/tools使用 .gcc选项告诉 GCC 的构建系统使用您首选目录中的库configure。显然，您必须为您想要从非标准位置使用的任何库添加这些内容 - 请参阅configure --help所有可用选项。
调整LD_LIBRARY_PATH不太可能对您有帮助，因为它只会改变动态链接器的行为ld.so，并且它（amlost）总是将/lib其/usr/lib作为最后的手段（请参阅man ld.so深入解释）。
附带说明一下，您可能想要获取 GCC 4.7.2 而不是旧的 4.6.3。
