Errors in CMakeLists.txt when building epanet-python package

[LittleZi]

I am trying to build epanet-python package on my computer. After running the code: python3 setup.py sdist bdist_wheel, it returned the cmake error at CMakeLists.txt. The cmake error I encoutered is specified below:

CMake Error at CMakeLists.txt:38 (ADD_SUBDIRECTORY):
  The source directory

    C:/Users/Ziyuan/AppData/Local/Programs/Python/Python37/Lib/site-packages/owa-epanet/EPANET

  does not contain a CMakeLists.txt file.

Appreicate a lot if any advices!

It looks like you are trying to build the wrapper from a clone of the repository. CMake cannot find EPANET because it is linked as a git submodule.

Assuming this is the case, please use the instructions provided: https://github.com/OpenWaterAnalytics/epanet-python/tree/dev/owa-epanet -- you will find notes there about initializing the EPANET submodule.

Thanks for your replying!

What I did is shown below:

C:\Users\Ziyuan\AppData\Local\Programs\Python\Python37\Lib\site-packages\owa-epanet>cd EPANET

C:\Users\Ziyuan\AppData\Local\Programs\Python\Python37\Lib\site-packages\owa-epanet\EPANET>git init
Reinitialized existing Git repository in C:/Users/Ziyuan/AppData/Local/Programs/Python/Python37/Lib/site-packages/owa-epanet/EPANET/.git/

C:\Users\Ziyuan\AppData\Local\Programs\Python\Python37\Lib\site-packages\owa-epanet\EPANET>git submodule update --init

C:\Users\Ziyuan\AppData\Local\Programs\Python\Python37\Lib\site-packages\owa-epanet\EPANET>cd ..

C:\Users\Ziyuan\AppData\Local\Programs\Python\Python37\Lib\site-packages\owa-epanet>python setup.py sdist bdist_wheel

Is it correct? But it still returned the same cmake error, I still feel confused about this issue.

[samhatchett]

you must run the git submodule update --init command from the base repo directory, not from inside EPANET directory.

[LittleZi]

Thanks for you replying again! Do you mean like this shown below?

C:\>cd epanet-python

C:\epanet-python>cd epanet-python-dev

C:\epanet-python\epanet-python-dev>cd owa-epanet

C:\epanet-python\epanet-python-dev\owa-epanet>git init
Reinitialized existing Git repository in C:/epanet-python/epanet-python-dev/owa-epanet/.git/

C:\epanet-python\epanet-python-dev\owa-epanet>git submodule update --init

C:\epanet-python\epanet-python-dev\owa-epanet>python setup.py sdist bdist_wheel

But finally, I still got the same error.

[samhatchett]

I think the git init command is resetting the repository and causing you to lose the submodule. The instructions provided do not suggest reinitializing the base repo, so try re-cloning the repo and following the instructions again.

[LittleZi]

Thanks for your patience! I am new to python. This time I did not run git init first.

C:\epanet-python\epanet-python-dev>cd owa-epanet

C:\epanet-python\epanet-python-dev\owa-epanet>git submodule update --init

C:\epanet-python\epanet-python-dev\owa-epanet>python setup.py sdist bdist_wheel

I am confused that it still returned the same cmake error.

[samhatchett]

What overall are you trying to accomplish? If it is just to use the wrapper, then a simple install via pypi should work (assuming you have the proper build tools). If you are trying to learn about and/or improve how the wrapper works, then cloning this repo and approaching it this way would work better.

assuming you want to get into the wrapper's internals, please provide more history of commands - did you download the repository, or clone it? what exactly is the git/console response to the commands?

[LittleZi]

I downloaded the repository and followed the instructions to build the epanet-python-packages, because I want to get coordinates of nodes in a water distribution network using this package.

[LittleZi]

Thank you very much! I have fixed the cmake error I encountered after running the code: python3 setup.py sdist bdist_wheel. And now, I changed directory into test folder, and ran the code: pipenv install ../dist/*.whl, an new error emerged shown below:

C:\Users\Ziyuan\epanet-python\epanet-python\owa-epanet\test>pipenv install ../dist/*.whl

Could you please give me some ideas about how to fix this issue? I have no ideas about it. Thanks a lot in advance!

[samhatchett]

should probably establish whether pipenv works properly on your system first, without trying to install the epanet wrapper. This looks like a pipenv problem.

[samhatchett]

I'm thinking this is fixed? I think you've opened some threads on the OWA forum - apologies if I am mistaken
