CentOS 7.6 编译安装最新版本GCC 9.2.0 实录

    最近打算用ScyllaDB做分布式数据库，但在CentOS7.6上发现GCC太老需要升级，GCC并不好编译需要很多依赖的和对应的版本，试了两天终于通过了，编译过程比较漫长朋友们需要耐心等待。以下是已经验证过可以正确编译安装的步骤给大家参考，欢迎指教！ 

 

注意：GCC是Linux的核心模块，升级可能会导致一些问题，请谨慎升级，升级之前做好备份工作。

Libraries have been installed in:
   /usr/local/gcc-9.2.0/lib/../lib64

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,-rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
