2015-01-09 05:53:07 -0500 | asked a question | Installing the image_view package I cannot compile the image_view package because it requires opencv 2.4.9 while I have 2.4.10. However, I was able to compile and install the vision-opencv package so I don't see why having opencv 2.4.10 should be an issue. Where can I configure the image_view source to build using opencv 2.4.10 instead of 2.4.9? |

2015-01-09 04:16:10 -0500 | answered a question | rosrun python executable The issue was in the package scripts. They used "#!/usr/bin/env python" which defaults to python3 on Archlinux. I changed it to "#!/usr/bin/python2". |
2015-01-09 04:13:59 -0500 | commented answer | rosrun python executable Afaik, PYTHONPATH points to libraries, not the executable. Changing it did not make a difference, however you led me on the right track. Thanks! |
2015-01-09 03:26:21 -0500 | asked a question | rosrun python executable How do you set which python executable rosrun uses? I am on Arch linux and I assume rosrun defaults to python 3 while trying to interpret python 2.7 source, which of course fails. EDIT: The issue was in the package scripts. They used "#!/usr/bin/env python" which defaults to python3 on Archlinux. I changed it to "#!/usr/bin/python2". |
2015-01-06 05:07:26 -0500 | asked a question | How to update library dependencies Hi, I am trying to install ros-indigo-depth-image-proc from the Arch user repository. The current version is 1.12.12-1 and it requires opencv 2.4.9, but I have opencv 2.4.10 which causes the build to fail. When I search the repository for dependencies, opencv 2.4.9 does not show up anywhere, only after the build files have been generated. How are these files generated and what process determines what version of opencv it depends on? And how do I change it to use 2.4.10 instead of 2.4.9? |

How do I force catkin to use the python 2.7 versions? |

2014-10-06 13:38:13 -0500 | commented answer | Catkin insists on using em.py 3.4 and nosetests 3.4, when configured to use python 2.7 This is an option, but it also means you cannot use the 3.4 version for anything else anymore, right? |
