无法 link 到现有的 libopenblas.so.0 DLL

Cannot link to existing libopenblas.so.0 DLL

我需要使用 libpca in C++, which depends on Armadillo, which in turn requires OpenBlas and lapack

我在 installing/configuring 这些依赖项中遇到了一些问题。

我正在使用 Red Hat 4.8.5-16,希望在 /my/dir/program/ 中编写代码和调用包。我没有 sudo 权限。

所有这些包都在 /my/dir/

中下载并解压缩

这是我遵循的步骤:

1. to install OpenBlas
    /my/dir/OpenBLAS-0.2.20$  make
    /my/dir/OpenBLAS-0.2.20$  make PREFIX=/my/dir/program/
    <Step 1 is successful>

2. to install lapack
    /my/dir/lapack-3.8.0$ mv make.inc.example make.inc
    /my/dir/lapack-3.8.0$ make
    <Step 2 is successful>

3. to install Armadillo
    /my/dir/armadillo-8.500.0$ cmake . -DCMAKE_INSTALL_PREFIX:PATH=/my/dir/pgrogram/
    /my/dir/armadillo-8.500.0$ make
    /my/dir/armadillo-8.500.0$ make install
    <Step 3 is successful>

4. to compile the example code
    /my/dir/armadillo-8.500.0$ cp examples/example1.cpp /my/dir/program
    /my/dir/program$ export LD_LIBRARY_PATH=/opt/intel/mkl/lib/intel64/:../OpenBLAS-0.2.20/:../armadillo-8.500.0/:./lib/:./lib64/:$LD_LIBRARY_PATH ;
    /my/dir/program$ g++ example1.cpp -o example1 -O2 -I./include -L./lib -L./lib64 -L../lapack-3.8.0 -L../OpenBLAS-0.2.20 -larmadillo -lopenblas -llapack  ;
    <There is no warning or error in compiling>

5. to run the example code
    /my/dir/program$ export LD_LIBRARY_PATH=/opt/intel/mkl/lib/intel64/:../OpenBLAS-0.2.20/:../armadillo-8.500.0/:./lib/:./lib64/:$LD_LIBRARY_PATH ;
    /my/dir/program$ ./example1

它returns

./example1: error while loading shared libraries: libopenblas.so.0: cannot open shared object file: No such file or directory

实际上libopenblas.so.0 dll位于./lib/,我已经添加了DLL路径。

因为我没有 root 权限,所以我不能 yum install openblas.x86_64 openblas-devel.x86_64 按照 this post 的建议。

我该怎么办?

对于 g++/ld 来说找到 libmkl_rt.so 是一回事。

运行 ./example1是新情况:"location information"必须重复→

export LD_LIBRARY_PATH=/opt/intel.. .. ...:$LD_LIBRARY_PATH && ./example1

请注意 export 命令是临时的:仅对当前 shell 会话有效。当您退出 shell 时,命令被取消。
