我在自己的路径 $HOME/gcc/gcc5.3.0 中安装了 gcc5.3。并成功构建项目。但是运行的时候出现这个错误：

../../lightgbm: /usr/lib64/libgomp.so.1: version `GOMP_4.0' not found (required by ../../lightgbm)
../../lightgbm: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by ../../lightgbm)
../../lightgbm: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.18' not found (required by ../../lightgbm)
../../lightgbm: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.14' not found (required by ../../lightgbm)
../../lightgbm: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by ../../lightgbm)

../../lightgbm: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.19' not found (required by ../../lightgbm)

并且 LD_LIBRARY_PATH 也已设置。 $HOME/gcc/gcc5.3.0/lib

和命令：ldd lightgbm

如何将 lddstd++.so.6 库路径更改为 $HOME/gcc/gcc5.3.0/lib？

感谢您的帮助！

我通过export LD_LIBRARY_PATH=/usr/local/gcc-5.3.0/lib:/usr/local/gcc-5.2.0/lib64:$LD_LIBRARY_PATH解决了
