如何解决“未找到BLAS API所需的库”问题？

Question

我试图通过简单地按照页面JDFTx上的说明来安装http://jdftx.org/CompilingBasic.html。

我已经从这里安装了Cygwin (视窗，x64)：https://cygwin.com/install.html。我还相信，我已经安装了必要的库，在这里列出：http://jdftx.org/Dependencies.html。

现在，当我在Cygwin64终端输入命令时：

cmake ../jdftx-VERSION/jdftx

我收到以下信息：

CMake Error at /usr/share/cmake-3.6.2/Modules/FindBLAS.cmake:690 (message):
  A required library with BLAS API not found.  Please specify library
  location.
Call Stack (most recent call first):
  /usr/share/cmake-3.6.2/Modules/FindLAPACK.cmake:165 (find_package)
  CMake-Modules/FindLAPACK_ATLAS.cmake:20 (find_package)
  CMakeLists.txt:85 (find_package)


-- Configuring incomplete, errors occurred!
See also "/cygdrive/c/jdftx/build/CMakeFiles/CMakeOutput.log".
See also "/cygdrive/c/jdftx/build/CMakeFiles/CMakeError.log".

解决方案是使用此命令，从而显式地指定库的位置：

cmake -DLAPACK_LIBRARIES=/usr/lib/liblapack.dll.a ../jdftx-1.4.1/jdftx

但是，现在我得到了以下输出，其中包含另一条错误消息：

有人知道我应该在cmake调用中使用什么其他选项吗？

谢谢!

Answer 1

解决办法是：

cmake -DLAPACK_LIBRARIES=/usr/lib/liblapack.dll.a -DMPI_CXX_LIBRARIES=/usr/lib/libmpi_mpifh.dll.a ../jdftx-1.4.1/jdftx

现在我意识到，这不是第二个错误的解决方案.

实际的解决方案是卸载所有相关库并安装以前的版本(而不是最新版本)。在我做完之后，一切都很好。
