I can see the variants listed:
opencv has the variants:
dc1394: Use libdc1394 for FireWire camera. Breaks compatibility with
Apple iSight FireWire camera.
debug: Enable debug binaries
python26: Add Python 2.6 bindings
* conflicts with python27
python27: Add Python 2.7 bindings
* conflicts with python26
qt4: Use qt4 backend for graphical interface.
tbb: Use Intel TBB
universal: Build for multiple architectures
I've got an error when trying to enforce the python26 variant:
Error: xorg-libxcb: Variant python26 conflicts with python27
Error: Unable to open port: Error evaluating variants
To report a bug, follow the instructions in the guide:
but so far it seems to install fine with the python27 variant.
Thank you very much for this !
