roslaunch gscam
Hi,
is there any solution to launch gscam from launch file ? gscam needs to be started directly from bin dir, else it throws errors. I've found no working solution to changedir from roslauch. Any idea ? Thanks and cheers Christian

Give us some details. What sort of errors? I'm pretty sure I've launched gscam automatically in the past...

As have I, perhaps your GSCAM_CONFIG environment variable is not set to an absolute path?

I bet it's because roslaunch doesn't use your environment variables, I'm having similar problems with PYTHONPATH. Did you find a solution?

There's a way to set environment variables in your launch file. This is how i've always set the GSCAM_CONFIG environment variable.

Yep, I ended up using the <env> tags as well.
