pywafo can not be compiled on windows #26
Comments
|
The mingw toolchain to compile the fortran extensions in pywafo on windows is broken at the moment. However, it is possible to compile only the c-extensions with a microsoft compiler. To make sure you use the microsoft compiler you can try this: [build] You can then try to run the following in a dos-prompt: If that does not work you can go to "c:\wafo\source\c_library" folder and run the following in a dos-prompt: python build_all.py and the manually copy the c_library.pyd file to the "c:\wafo" folder. |

Hi Per, Thank you very much for your reply. I have the feeling that I am getting I did what you told me (adding the distutils.cfg with compiler=msvc (btw: Anyway, the first command does not work The second one with python build_all.py give the log as in the log.txt file Errors start to be raised from Building import library (arch=AMD64): I read somewhere on a mingw side that the libpython27.a should be generated Would you have a clue to fix this ? Any hints appreciated! Regards 2016-06-24 14:57 GMT+02:00 Per A. Brodtkorb notifications@github.com:

Hi Per, Excellent, I fixed this problem. I was able to compile the Then I did the following command : This runs but end with an error message Anyway, still the c_library.pyd was created. However, I I just copy the So altough the setup script is not working out of the box, I could finally fix it, which is a releave Thanks for the help ! If you want I have an exampe rain_flow_example.py script which I added to the tutorials which is using this cycle_astm algorithm Regards |

For those interested. Using the same trick as above I was able to compile pywafo for python 3.5.3 as well. For this, I had to first update the Microsoft visual C++ compiler to version 15.0, which can be downloaded from here For the fortran compiler I installed MinGW version 5.3.0-3 and used the gfortran.exe coming with this. Then I ran: This fails at the end with the same message as above, but again, if you copy the c_library.pyd from the build to the wafo directory you should be able to run pywafo including the rainflow algoritm. Attached an updated version of the rain_flow example. |
I have used the latest version of pywafo. I need to have the compiled version since I need the cylce_astm routine. In order to compile the libary I have run
python setup.py bdist_wheel -d build
I have both the mingw compiler and the microsoft visual studio C++ compiler installed, but I can not find how to choose which version should be used and even can not see which version is being used.
I get an error message related to not be able to read the python27.dll
I have included the total outpyt to the log.txt file.
Key message I think is the first warning saying:
Building import library (arch=AMD64): "C:\Apps\Anaconda\Anaconda250\libs\libpython27.a" (from C:\Apps\Anaconda\Anaconda250\python27.dll)
objdump.exe: C:\Apps\Anaconda\Anaconda250\python27.dll: File format not recognized
Traceback (most recent call last):
File "setup.py", line 83, in
setup_package_pyscaffold()
etc.
File "C:\Apps\Anaconda\Anaconda250\lib\site-packages\numpy\distutils\mingw32ccompiler.py", line 276, in generate_def
raise ValueError("Symbol table not found")
ValueError: Symbol table not found
so somehow the python27.dll is not recognised, which I though was related to the mingw compiler.
The question is: how can I fix this or how can I ensure that the CL compiler (msvC++) is used ?
Hopefully you can help me!

Eelco
