Not a question, but wanted to post this in case anyone else had the same problem. I had a problem makeing the RGBDSLAM tool from OpenSlam.org . I had the following error when trying to build it... ...

Linking CXX executable ../bin/rgbdslam

/usr/bin/ld: cannot find -lgsl

collect2: ld returned 1 exit status

make[3]: *** [../bin/rgbdslam] Error 1

make[3]: Leaving directory `/home/aaron/myRosDir/rgbdslam/build'

make[2]: *** [CMakeFiles/rgbdslam.dir/all] Error 2

make[2]: Leaving directory `/home/aaron/myRosDir/rgbdslam/build'

make[1]: *** [all] Error 2

make[1]: Leaving directory `/home/aaron/myRosDir/rgbdslam/build'

make: *** [all] Error 2

Taking a wild guess I downloaded GSL from GNU Scientific Library

http://www.gnu.org/software/gsl/

And the build completed!

ps. this is my first post. How do I make code show up in a scrollable window?

For code formatting, indent with 4 spaces (Ctrl+K is the shortcut, or use the little "101010" icon). Or sometimes just wait and someone will edit your post for you. :-)

Looks like you figured out the problem. However, just as a general tip, whenever you encounter an error like that, it's best to look in your Synaptic Package Manager to see if you can easily download that missing packages.

If that doesn't work, you can typically google search the missing piece. That's what works for me every time.

Thanks, I'll remember that. I'm new to linux so I didn't even know about SPM.

Actually gsl is only required if you want to use the experimental GICP support. I now updated CMakeLists.txt such that this error only occurs if GICP use is activated.
