Problems with installation on cygwin #34

Closed KirillShe closed 6 years ago

KirillShe commented 6 years ago

I followed the installation guide on cygwin. After typing the command "cmake ../jdftx-git/jdftx/" I got the follow output: ` -- The C compiler identification is GNU 6.4.0 -- The CXX compiler identification is GNU 6.4.0 -- Check for working C compiler: /usr/bin/cc -- Check for working C compiler: /usr/bin/cc -- works -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Detecting C compile features -- Detecting C compile features - done -- Check for working CXX compiler: /usr/bin/c++.exe -- Check for working CXX compiler: /usr/bin/c++.exe -- works -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - done -- Detecting CXX compile features -- Detecting CXX compile features - done -- Found Git: /usr/bin/git.exe (found version "2.15.0") -- Git revision hash: 8120d294 -- Forcing static linking for Cygwin/Windows -- Looking for gsl_integration_glfixed_point -- Looking for gsl_integration_glfixed_point - found -- Found GSL: /lib/libgsl.dll.a -- Looking for pthread.h -- Looking for pthread.h - found -- Looking for pthread_create -- Looking for pthread_create - found -- Found Threads: TRUE -- Found FFTW3: /lib/libfftw3threads.dll.a /lib/libfftw3.dll.a -- Looking for sgemm -- Looking for sgemm_ - not found CMake Error at /usr/share/cmake-3.6.2/Modules/FindBLAS.cmake:690 (message): A required library with BLAS API not found.

Later, I typed: cmake -DLAPACK_LIBRARIES=/usr/lib/liblapack.dll.a ../jdftx-git/jdftx/ and after it tried the follow command: cmake -DLAPACK_LIBRARIES=/usr/lib/liblapack.dll.a -DMPI_CXX_LIBRARIES=/usr/lib/libmpi_mpifh.dll.a ../jdftx-git/jdftx/ These command I saw on the webpage https://stackoverflow.com/questions/50928885/how-to-solve-the-issue-a-required-library-with-blas-api-not-found. And got the same results. I typed "make tests, I got: Running tests...

` I have no idea how to treat this issue. Please, help me.

shankar1729 commented 6 years ago

Recent updates to cygwin seems to have broken our compilation suggestions for it. Try adding -DLAPACK_LIBRARIES=/usr/lib/liblapack.dll.a to your cmake commandline.

Also, please note that jdftx performance in cygwin can be quite poor; most of our users use it on unix/linux systems.

Best, Shankar

KirillShe commented 6 years ago

I added -DLAPACK_LIBRARIES=/usr/lib/liblapack.dll.a to my cmake commandline. All test are failed. LastTest.log contains: ` Start testing: Jul 25 14:43 GMT

shankar1729 commented 6 years ago

Tests are failing because compilation is failing and there is no executable. So we need to get make to work correctly first before running make test.

What were the results of cmake and make after the previous modifictaion I suggested?

Cheers, Shankar

KirillShe commented 6 years ago

I reported exactly the results in LastTest.log after the previous modifictaion you suggested. Cmake and make finished without any error. jdft.exe is exist, its size is 15 MB.

shankar1729 commented 6 years ago

Oh I see. What output do you get if you run ./jdftx.exe in the build directory? Can you also post your CMakeCache.txt?

KirillShe commented 6 years ago

No any output. Executing take no time.

KirillShe commented 6 years ago

CMakeCache.txt `

This is the CMakeCache file.

For build in directory: /home/jdftx-git/build

It was generated by CMake: /usr/bin/cmake.exe

You can edit this file to change values found and used by cmake.

If you do not want to change any of the values, simply exit the editor.

If you do want to change a value, simply edit, save, and exit the editor.

The syntax for the file is as follows:

KEY:TYPE=VALUE

KEY is the name of a variable in the cache.

TYPE is a hint to GUIs for the type of VALUE, DO NOT EDIT TYPE!.

VALUE is the current value for the KEY.

I recently encountered the Windows Subsystem for Linux, which allows installing a minimal linux distro like Ubuntu on top of Windows. I have tested this option and found that it gives much better performance than Cygwin for JDFTx, almost (but not quite) comparable to the performance on a native Linux install.

This is also much easier to install and for us to support, since it essentially amounts to working on Linux. I have updated the build instructions for Windows to recommend this by default.

Best, Shankar
