"undefined reference" in building cuDSS examples

[alephchang]

Hi, I follow cuDSS/examples/README.md to build the example(linux). When I run "cmake --build build --verbose", it reports unrefined reference error:

Hi! What OS and compiler did you use? I suspect, that you need to pass -lstdc++ additionally but I am curious to learn your setup. Current CMakeLists.txt expects a compiler which can link -lstdc++ implicitly.

Thanks, Kirill

Hi Kirill, The default compiler is too old: c++ (GCC) 4.8.5 20150623 (Red Hat 4.8.5-44) I change a new one and add -lstdc++. The undefined reference fixed. Thanks, Yijiang
