Re: [HTCondor-users] htcondor python bindings for python3 ?

[Aki Ketolainen <akik@xxxxxxxxxxx>]

Hi,

(Sorry for this second message, the first one was rejected.)

I've tried to "UW" compile htcondor from source but I haven't been able 
to complete the compile and
produce lib/python/htcondor.so and lib/python/classad.so so that python3 
would be able to use them.

If I set the cmake variables for the python3 version in htcondor main 
CMakeLists.txt

set(PYTHON_LIBRARY "/sw/python/3.4.4/lib/libpython3.so")
set(PYTHON_INCLUDE_DIR "/sw/python/3.4.4/include/python3.4m")
set(PYTHON_EXECUTABLE "/sw/python/3.4.4/bin/python3.4m")

and have python3 in my path, boost compile fails. By default the cmake 
compile tries to compile
boost 1.49.0 and according to you, boost 1.49.0 is not compatible with 
python3.

So I'd need to find a way to have the cmake process try to use boost 
1.54.0 instead of 1.49.0 ?
I haven't found where to change that. I didn't find the documentation 
for doing the proper build,
src/README.building talks about doing the UW build.

I've successfully compiled boost 1.54.0 with

$ ./bootstrap.sh --with-python=/sw/python/3.4.4/bin/python3 
--with-python-root=/sw/python/3.4.4 \
--libdir=/sw/python/3.4.4/lib 
--includedir=/sw/python/3.4.4/include/python3.4m
$ ./b2

My host is a CentOS 6.7 with python 3.4.4 compiled from source.

Thank you for your help,

Aki
