but without emcmake success. cmake .. -DUSE_CUDA=0 -DUSE_OPENCV=0 -DUSE_OPENMP=0 -DUSE_CPP_PACKAGE=1

@Yongle-Fu it looks like when you use emcmake, the build system can't find a blas library. Which blas are you using?

Yongle-Fu commented 4 years ago

openblas 0.3.10_1 /usr/local/opt/openblas

szha commented 4 years ago

hmm it should have been found in this path https://github.com/apache/incubator-mxnet/blob/master/cmake/Modules/FindOpenBLAS.cmake#L29. What might be happening is that the emcmake wrapper didn't pass on the environment variables that helped you find openblas due to its choice of shebang. Try setting ${OpenBLAS_HOME} instead.

resolved by add setting

IF(NOT OpenBLAS_LIB) set(OpenBLAS_INCLUDE_DIR "/usr/local/opt/openblas/include") set(OpenBLAS_LIB "/usr/local/opt/openblas/lib/libopenblas.dylib") ENDIF()
