执行configure；参数可以直接copy 当前版本的Configured with:的参数值，修改下--prefix=/usr 安装目录就可以了；不指定该参数会默认安装到/usr/local目录下
保留你需要的参数
[root@xuperior-pc gcc-10.2.0]# ./configure --enable-bootstrap --enable-languages=c,c++,lto --enable-shared --enable-threads=posix --enable-checking=release --enable-multilib --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-gnu-unique-object --enable-linker-build-id --with-gcc-major-version-only --with-linker-hash-style=gnu --enable-plugin --enable-initfini-array --with-isl --enable-offload-targets=nvptx-none --enable-gnu-indirect-function --enable-cet --with-tune=generic
然后执行
make && make install
等待漫长的编译过程结束.............
等了很久冒出来个这玩意
/usr/include/gnu/stubs.h:7:11: fatal error: gnu/stubs-32.h: No such file or directory
7 | # include <gnu/stubs-32.h>
| ^~~~~~~~~~~~~~~~
compilation terminated.
赶紧查一下在哪里

[root@xuperior-pc gcc-10.2.0]# yum install glibc-devel
安装好，再继续.....
[root@xuperior-pc gcc-10.2.0]# yum -y install glibc-devel.i686
还不行。要装64位的
ten thousand years later.......
终于编译完了。再去install。

如果prefix参数指定其他目录可以自行拷贝：bin include lib lib64 libexec share到usr或者local下
编译脚本核运行的时候如果不想改默认版本请自行指定gcc
/usr/local/bin/g++
/usr/local/bin/gcc
或者临时修改环境变量
export PATH=${YOUR_DIR}/gcc-10.2.0/bin:$PATH
运行时指定动态库加载路径
export LD_LIBRARY_PATH=${YOUR_DIR}/gcc-10.2.0/lib64:$LD_LIBRARY_PATH
Done！！
