I’m building from source, and build completes only until linking libtorch related stuff (fails with undefined references).
how to solve it? It happens in both master and tagged version.
I followed instructions here https://github.com/pytorch/pytorch#from-source 7
Following Undefined symbol when import lltm cpp extension 6
I added -D_GLIBCXX_USE_CXX11_ABI=0 ti CFLAGS after the attempt without it failed.
The relevant error:
