inglada commented on issue #12837: [cpp-package]Wrong GLIBCXX version for cpp-package examples URL: https://github.com/apache/incubator-mxnet/issues/12837#issuecomment-430412249 Hi, Thanks for your answer. I helped me found some additional info. I am using a gcc version which is installed in /usr/local/ and made available through debian/ubuntu "alternatives" mechanism via symlinks in /usr/bin/. The problem is that libmxnet is using /usr/lib/x86_64-linux-gnu/libstdc++.so.6 instead of the one corresponding to the compiler used for building. If I use the gcc 6.3 version in /usr/bin/ everything goes OK. This is not a sane behaviour, since it means that something in mxnet build process is not using the compiler's default libstdc++; but the one which is in /usr/lib/. The "alternatives" mechanism works fine for many libraries I build from source. There may be something hard coded in the provided Makefile. I can try to investigate further if you give me some hints. Is CMake a supported build process? Thanks.
