Python compilation failing on Windows/debug

[Gabriel Petrovay]

2171 - python (Failed)

If the python version is not good, CMake should complain.

    Start 2171: python

2171: Test command: D:\Software\Python27\python.exe python_test.py

marked as EXPECTED_FAILURE under Windows in:
doc\python\examples\CMakeLists.txt

[Rodolfo Ochoa (rodolfo-ochoa)]

Python bindings and tests are fixed in windows, there is also a tutorial in: http://www.zorba-xquery.com/index.php/tutorials/zorba-xquery-in-python-windows-installation/

[Gabriel Petrovay (gabipetrovay)]

I also did some CMake code cleanup.

Wrong bug closed. I meant that for 3193268

[Gabriel Petrovay (gabipetrovay)]

Still not working:
In Debug mode SWIG python does not link. See bug#3375314
In Release mode:

2036 - python (Failed)
2210 - python_test01 (Failed)
2211 - python_test02 (Failed)
2212 - python_test04 (Failed)

2216 - python_test07.2 (Failed)
2217 - python_test08 (Failed)
2218 - python_test10 (Failed)

Is your _zorba_api.pyd file where python can find it?
the error you show is because python can't find this file...

[Gabriel Petrovay (gabipetrovay)]

An how to make this happen?

[Rodolfo Ochoa (rodolfo-ochoa)]

Usually, this file in my build is originally in this directory:
...zorba\build\swig\python\Release
so I move it one directory up, to:
...zorba\build\swig\python
and that's enough to run tests, but these could be better options for other environments:
- somewhere with PATH env variable
- pythonPath\libs

[Gabriel Petrovay (gabipetrovay)]

There must be a solution where I don't have to do anything. Cmake is responsible for that.

>Usually, this file in my build is originally in this directory:
>...zorba\build\swig\python\Release

I am building with nmake so I don't have those subdirectories.

>- somewhere with PATH env variable

I don't (want to) change path variables to build Zorba

>- pythonPath\libs

I also don't (want to change Python installation) (One reason is that when I uninstall Python and if I copy smth into it, it leaves garbage and it does not clean up the installed directory.

So for this Cmake has to be adjusted.
The only thing in the user's control is ZORBA_SUPPRESS_SWIG. The rest should happen behind the scenes.

[Rodolfo Ochoa (rodolfo-ochoa)]

If you are using NMake you shouldn't have this problem because NMake don't create Release or Debug directories, I can't reproduce this issue, could you please indicate your Python version and the results of python swig api project compiling?

[Gabriel Petrovay (gabipetrovay)]

Apparently I do have the problem with NMake.

The output above reveals the version: 2.7

And as mentioned ine previous comment, for the compulation ERRORS see: bug 3375314

[Rodolfo Ochoa (rodolfo-ochoa)]

I also have Python 2.7, can you provide the result of nmake compilation?

LINK : fatal error LNK1104: cannot open file 'python27_d.lib'

[Rodolfo Ochoa (rodolfo-ochoa)]

for instance, you cannot run python test because the api binding is not compiled, the file 'python27_d.lib' is missing, if you want to get python api in debug mode you must provide python debug library (python27_d.lib), if you can't get it from the site you must compile python yourself to get it... if you compile in release mode you should have no problems compiling and running tests...

[Rodolfo Ochoa (rodolfo-ochoa)]

This info was already on documentation...
