Due to the macros and sheer number of type combinations we often run in to undefined symbols when linking.

We typically use this command on linux to find issues: nm -uC libnd4j/blasbuild/cpu/blas/libnd4jcpu.so

or cuda: nm -uC libnd4j/blasbuild/cuda/blas/libnd4jcuda.so

You can also do the same for just undefined: nm -C --undefined-only libnd4jcpu.so nm -C --undefined-only libnd4jcuda.so
