Revision history [back]

Lets wrap up the problem as compact as possible ...

I have two possible configurations

1. SETUP 1: Ubuntu 12.04 - CodeBlocks 10.05 - GCC compiler 4.6.3 - G++ compiler 4.6.3
2. SETUP 2: Ubuntu 14.04 - CodeBlocks 13.12 - GCC compiler 4.6.4 - G++ compiler 4.8.2

On both systems I fire up codeblocs, make a new console project and copy the following code - pastebin due to not screwing the main point - to the main.cpp file.

I then configure my codeblocks in a similar way. I add the PvAPI.h file to the project and fire up the linker options. I then add all the following dependencies to link libraries:

/home/spu/Software/AVT_sdk/lib-pc/x64/4.5/libPvAPI.a
/usr/lib/x86_64-linux-gnu/librt.a
/usr/lib/x86_64-linux-gnu/libpthread.a

And to the other linker options

`pkg-config opencv --libs`

So far so good, until I decide to built the actual project.

1. SETUP 1: everything builds fine and I can grab frames from the AVT cam.
2. SETUP 2: results in a giant list of errors in the pthread lib

You can see the errors below

UPDATE

I can confirm that it has to be something outside OpenCV causing these errors. Used exactly the same OpenCV version, build with same parameters but error still persists on 14.04 system. However, if anyone has had a similar experience, feel free to share!
