mjmg commented on issue #8974: MXNET compatibility with MKL libraries bundled in Microsoft R Open
URL: https://github.com/apache/incubator-mxnet/issues/8974#issuecomment-349926412
 
 
   I already did something equivalent for the libraries in /usr/local/lib prior to make rpkg
   ```
   # echo "/usr/local/lib" >> /etc/ld.so.conf.d/local-lib.conf
   # ldconfig
   ```
   These are my make flags for building mxnet for MKL CPU acceleration when since mxnet 1.0.0 came out:
   ```
   USE_OPENCV=1 USE_BLAS=mkl USE_MKLML=1 USE_MKL2017=1 USE_MKL2017_EXPERIMENTAL=1  USE_GPERFTOOLS=1
   ```
   
   But it seems if I add the flag "USE_LAPACK=1", there are incompatibilities with "USE_BLAS=mkl" with several lapack routines unable to be found during linking stage if I don't install LAPACK development packages separately. Since there are LAPACK routines in the following libraries from MRO:
   ```
   libmkl_core.so      
   libmkl_gnu_thread.so  
   libRblas.so 
   libgfortran.so.1  
   libmkl_gf_ilp64.so  
   libmkl_vml_def.so     
   libRlapack.so
   libiomp5.so       
   libmkl_gf_lp64.so   
   libmkl_vml_mc3.so     
   libR.so
   ```
   I was wondering if MXNET could be able to link from these without downloading the full MKL installation or installing openblas/atlas/lapack separately.
