make error - libxsmm #4

Open sujing1 opened 7 years ago

sujing1 commented 7 years ago

Issue summary

make libxsmm fails with f77 errors when building SkimCaffe. However, libxsmm can be built successfully as a standalone library. I'd appreciate any advices!

make_libxsmm log Makefile.config

Steps to reproduce

1.

source /opt/intel/compilers_and_libraries/linux/bin/compilervars.sh -arch intel64 -platform linux
. /opt/intel/compilers_and_libraries/linux/bin/compilervars.sh -arch intel64 -platform linux

2.

$ cd ./SkimCaffe-intel_scnn
$ make libxsmm -j4

Error Log

Trying to build the latest release, but I find different errors. Would this be related to CUDA or cuDNN?

Thanks for reporting this issue. Regarding the f77 error when building libxsmm, if the installed Intel compiler includes Fortran compiler as well, you shouldn't see the error. I'll also look at if I can remove the dependency to the Intel Fortran compiler as soon as I have time. Regarding the spotrf/dpotrf/spotrs/dpotrs errors, perhaps Intel MKL is not installed in your system or not configured? Anyway, those function calls are not needed in winograd.hpp anymore. I've just pushed the changes. Please let me know how it goes.

It looks like this can be resolved by adjusting https://github.com/IntelLabs/SkimCaffe/blob/intel_scnn/Makefile#L481 such that FC= is included into the make-line (which is equivalent to FORTRAN=0). In any case this removes the dependency of a FORTRAN compiler when building LIBXSMM.

Thanks Hans! Fixed and pushed.
