#194 Unable to enable python support on 3.2.1

[Pedro F. Giffuni]

On FreeBSD, even after setting the arguments with
-Denable-python=ON -Denable-python-bindings=ON (which used to work in 3.1.x version)
when I look at CMakeCache.txt
...
//enable python support
enable-python:BOOL=OFF

//enable python bindings support
enable-python-bindings:BOOL=OFF
...

Hi Pedro,
Thanks for reporting the issue.
However, I can't reproduce it.
I successfully tested the master branch last week and the 3.2.1 release this morning....

cmake ../tfel-3.2.1 -DCMAKE_BUILD_TYPE=Release -Dlocal-castem-header=ON -Denable-aster=ON -Denable-abaqus=ON -Denable-calculix=ON -Denable-ansys=ON -Denable-europlexus=ON -Denable-python=ON -Denable-python-bindings=ON -Denable-comsol=ON -Denable-diana-fea=ON -DPython_ADDITIONAL_VERSIONS=3.6 -DCMAKE_INSTALL_PREFIX=/home/tom/codes/tfel/3.2.1/install

I did this on FreeBSD 12.0...

Two questions:

• have you installed boot python ?
• what is the release of FreeBSD that you use ?

Best,
Thomas

Hi;
Boost python is installed and I am using FreeBSD 12.1 but I doubt the FreeBSD version is relevant..

If it works for you then It may be a pilot (mine) error: I am updating the FreeBSD port and the method I used to set up the python build is not working anymore. I am attaching my latest port attempt in case you want to try.

Alternatively feel free to close the ticket: you are not excpected to have to clean my mistakes :).

Hi Pedro,
I am commited to make a TFEL works nicely in FreebBSD.
I'll give FreeBSD 12.1 a try today.
Best,
Thomas

Hi;
Can you try this?

-Denable-python:BOOL=TRUE -Denable-python-bindings:BOOL=TRUE

It is actually what our ports tree does.

[Helfer Thomas]

I did !
However I did not have the time to test FreeBSD 12.1

[Helfer Thomas]

It just remind me that FindBoost has a nasty bug in 1.70. Are you using this version ?

[Pedro F. Giffuni]

I have
py27-boost-libs-1.71.0
py36-boost-libs-1.71.0

In any case ... we added a workaround to the FreeBSd port and it works for now.
It was just committed.

[Helfer Thomas]

May I ask what is the workaround ?

[Pedro F. Giffuni]

You may ask, but its a workaround because I don't understand it.

In the tfel port Makefile we used to have this:
PYTHON_CMAKE_ARGS= -Denable-python=ON -Denable-python-bindings=ON
it stopped working and the documended recommendation is to use this:
PYTHON_CMAKE_ON= enable-python enable-python-bindings
which also doesn't work. The same format does work for the calculix and aster options.
However using this works:
PYTHON_CMAKE_ON= -Denable-python=ON -Denable-python-bindings=ON

So I have to check with ports developers to see what is going on here.

[Helfer Thomas]

Closed as related to FreeBSD port mechanism

[Pedro F. Giffuni]

I agree with closing the ticket .. thanks!

For the record though, the problem escalated: with python3 it doesn't detect some headers so I had to disable the python option for the port altogether. :(.

[Helfer Thomas]

That's really strange, I don't have any trouble...
Anyway, thanks for your effort in packaging TFEL/MFront !
