Question

我正在尝试安装Armadillo link。

但是，make命令会抱怨“clapack.h” 确实存在于/usr/include/atlas/clapack.h 位置。一些帮助将不胜感激。

注意，如果我将该文件复制到/ usr / include /然后make：

，我可以运行

$ sudo cp /usr/include/atlas/clapack.h /usr/include/
$ make

但是，我不习惯在多个位置制作同一文件的副本。 可能有危险吗？

这是我到目前为止所做的：

1）我下载并编制了犰狳库。之后，我改变了CMakeLists.txt中的以下行（我有Lapack，Blas，Atlas）：

set(ARMA_USE_LAPACK    true)
set(ARMA_USE_BLAS      true)
set(ARMA_USE_ATLAS     true)
set(ARMA_USE_HDF5_ALT  false)
set(ARMA_USE_ARPACK    false)
set(ARMA_USE_CXX11_RNG false)
set(ARMA_USE_WRAPPER   true )

然后“$cmake .”成功运行并找到Lapack, Blas and Atlas。但是，当我运行“make”时，它会出现以下错误（代码include_atlas.hpp中标记的第26行）：

$ make

当我查看include_atlas.hpp时，似乎ARMA_USE_ATLAS仍设为false：

#if defined(ARMA_USE_ATLAS)
  #if !defined(ARMA_ATLAS_INCLUDE_DIR)
    extern "C"
      {
      #include <cblas.h>
      #include <clapack.h>
      }
  #else
    #define ARMA_STR1(x) x
    #define ARMA_STR2(x) ARMA_STR1(x)

    #define ARMA_CBLAS   ARMA_STR2(ARMA_ATLAS_INCLUDE_DIR)ARMA_STR2(cblas.h)
    #define ARMA_CLAPACK ARMA_STR2(ARMA_ATLAS_INCLUDE_DIR)ARMA_STR2(clapack.h)

    extern "C"
      {
      #include ARMA_INCFILE_WRAP(ARMA_CBLAS)
      #include ARMA_INCFILE_WRAP(ARMA_CLAPACK)      // This is line no 26
      }

    #undef ARMA_STR1
    #undef ARMA_STR2
    #undef ARMA_CBLAS
    #undef ARMA_CLAPACK
  #endif
#endif

如果我将ARMA_CLAPACK替换为"/usr/include/atlas/clapack.h"，它仍会抱怨：

Answer 1

我检查make输出后指向错误的atlas目录时cmake . cmake运行ATLAS_INCLUDE_DIR = /usr/include/时出现同样的问题，即它指向ATLAS_INCLUDE_DIR = /usr/include/atlas其中应该指向-- Found ATLAS: /usr/lib/libatlas.so -- Found BLAS: /usr/lib/libblas.so -- Found LAPACK: /usr/lib/liblapack.so -- MKL_FOUND = NO -- ACMLMP_FOUND = NO -- ACML_FOUND = NO -- OpenBLAS_FOUND = NO -- ATLAS_FOUND = YES -- BLAS_FOUND = YES -- LAPACK_FOUND = YES -- ATLAS_INCLUDE_DIR = /usr/include/ -- ARPACK_FOUND = NO -- -- *** Armadillo wrapper library will use the following libraries: -- *** ARMA_LIBS = /usr/lib/libatlas.so;/usr/lib/libblas.so;/usr/lib/liblapack.so。

CmakeCache.txt

我通过在make文件中添加正确的路径来解决此问题。之后，make install和g++ -O2 -o example1 example1.cpp -larmadillo运行良好。

但是在使用

编译示例后运行时出现此错误

./example1: error while loading shared libraries: libarmadillo.so.4: cannot open shared object file: No such file or directory

错误是

libarmadillo.so

注意：上述错误可以通过在libarmadillo.so.4目录中创建/usr/lib和{{1}}的符号链接来解决。
