caffe with openblas

[tachiang]

Issue summary

runtime error when using caffe+openblas

Steps to reproduce

1. openblas installation
   git clone https://github.com/xianyi/OpenBLAS.git
   cd OpenBLAS
   make -j4
   make install
2. edit Caffe Makefile.config
   BLAS := open
   BLAS_INCLUDE := /opt/OpenBLAS/include
   BLAS_LIB := /opt/OpenBLAS/lib
3. Make Caffe again
4. export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/OpenBLAS/lib
5. train my network using Caffe
6. core dump
   Core was generated by `./build/tools/caffe train --solver=examples/spatialmapping/liunet_solver.protot'.
   Program terminated with signal 11, Segmentation fault.

p.s. caffe train works well when using caffe+atlas
