Question

我试图在Ubuntu 16.04中使用OpenBLAS编译Caffe。我已经下载并编译了OpenBLAS make NO_AFFINITY = 1 USE_OPENMP = 1 OpenBLAS编译很好，所有测试也都运行

OpenBLAS build complete. (BLAS CBLAS LAPACK LAPACKE)

  OS               ... Linux             
  Architecture     ... x86_64               
  BINARY           ... 64bit                 
  C compiler       ... GCC  (command line : gcc)
  Fortran compiler ... GFORTRAN  (command line : gfortran)
  Library Name     ... libopenblas_sandybridgep-r0.2.20.dev.a (Multi threaded; Max num-threads is 4)

 Use OpenMP in the multithreading. Because of ignoring OPENBLAS_NUM_THREADS and GOTO_NUM_THREADS flags, 
 you should use OMP_NUM_THREADS environment variable to control the number of threads.

然而，在Caffe安装中与OpenBLAS libs链接会出现以下错误

链接CXX可执行文件upgrade_net_proto_binary /opt/OpenBLAS/lib/libopenblas.so：未定义引用`GOMP_parallel@GOMP_4.0' collect2：错误：ld返回1退出状态 tools / CMakeFiles / upgrade_net_proto_binary.dir / build.make：129：目标工具/ upgrade_net_proto_binary＆＃39;失败 make [2]： * [tools / upgrade_net_proto_binary]错误1 CMakeFiles / Makefile2：403：目标＆＃39;工具的配方/ CMakeFiles / upgrade_net_proto_binary.dir / all＆＃39;失败 make [1]：* [tools / CMakeFiles / upgrade_net_proto_binary.dir / all]错误2

Answer 1

最有可能的原因是您链接到已编译的OpenBLAS而不是安装它并链接到安装。运行make后，您应该运行make install PREFIX=/path/to/install/OpenBLAS，然后您应该链接到已安装的版本。

编译Caffe时出错
