下载GCC编译安装

yum groupinstall "Development Tools"
wget https://ftp.gnu.org/gnu/gcc/gcc-7.3.0/gcc-7.3.0.tar.gz --no-check-certificate
tar -zxvf  gcc-7.3.0.tar.gz
cd gcc-7.3.0/

cd build
../configure --enable-checking=release --enable-languages=c,c++  --disable-multilib
make
make install
 

验证

# 检查验证
strings /usr/lib64/libstdc++.so.6 | grep 'CXXABI'
# 如未发现则全局查找 
find / -name "libstdc++.so.*"
# 发现刚才编译的在这
/usr/local/lib64/libstdc++.so.6.0.24
# 创建软连接
cp /usr/local/lib64/libstdc++.so.6.0.24 /usr/lib64/
cp /usr/lib64/libstdc++.so.6 /home/libstdc++.so.6.bak
rm /usr/lib64/libstdc++.so.6
ln -s /usr/lib64/libstdc++.so.6.0.24 /usr/lib64/libstdc++.so.6
# 检查验证
strings /usr/lib64/libstdc++.so.6 | grep 'CXXABI'
