gcs_image_bridge.cpp compiling error

[TSC21]

Guys,

How's things going? I'm coming back to work at the project finally :D Doing some clean up on my laptop. Installed 14.04 with Indigo. But in my workspace, when doing catkin_make, I get this on gcs_image_bridge.cpp compilation:

[ 98%] Built target mavros_plugins

Maybe opencv related? I installed the version which comes with the indigo repo. Any advice?

Hope to continue getting some improvements on the project :)

Best, Nuno

BTW, pkg-config --libs opencv on terminal gives me:

[TSC21]

Update: Uninstalled the opencv version of Indigo, and installed opencv from source: http://docs.opencv.org/doc/tutorials/introduction/linux_install/linux_install.html Same result! What can be wrong then?

[vooon]

Remove your build and devel dirs.

[TSC21]

Already did it. same stuff

[vooon]

Why do you use ros version? As i know it wants system library.

Where 2.4.8 links is a fix for building mavros on 14.10 + Indigo.

[TSC21]

Solved! I had 2.4.8 instead of 2.4.9, Installing 2.4.9 solved. Closing now!

[vooon]

Hmm, 2.4.8 is a version in 14.04, and i did that links to solve build deps.

[TarekTaha]

@TSC21 I am facing the same issue on Ubuntu 14.04, how did you install the 2.4.9 Ubuntu 14.04 has only the 2.4.9 !

[mhkabir]

@blackcoder Do a source install please

[vooon]

Problem not in opencv version! I used 2.4.9 because it shipped in Ubuntu 14.10. And it builds fine on jenkins (indigo trusty 0.10.1), so 2.4.8 is ok.

Not ok is mixing ros opencv package (placed in /opt/ros) and system. Because ros package provides experimental opencv3.

[TarekTaha]

@vooon you are right ! I simply removed ros-indigo-opencv3 and it compiled correctly. For future reference, people facing the same problem should do the same:

sudo apt-get remove ros-indigo-opencv3

[zhaobinglei]

Remove your build and devel dirs.

Thank you so much! I solved this problem after:

1. $ sudo apt-get install ros-indigo-opencv3
2. delete /ros_ws/devel and /ros_ws/build
3. $ catkin_make
