I'm trying to build Opencv 2.4.11 on RHEL 6.6 server. I can build the source without the python bindings, but if I include the python bindings the compile crashes. For some reason the build ignores the cmake settings and tries to include files from wrong location. Can anyone tell me how to get the python bindings to work? I have tried to build different versions of opencv for two weeks now and it really feels impossible(on ubuntu it builds just fine), I would really appreciate some help.
Here is my build setup:
#!/bin/bash
source /home/lato/karjaljo/sandbox/OCV2.4/venv/bin/activate
export PYTHON_EXECUTABLE=/home/lato/karjaljo/sandbox/OCV2.4/venv/bin/python
