Problem installing gscam

asked 2011-03-18 06:44:25 -0500

Hi, I'm trying to install the gscam packet for Rovio. I've checked out the package into the directory /opt/ros/diamondback/stacks. When I try to use the command rosmake --rosdep-install gscam I always get this error "mkdir: cannot create directory `build': Permission denied". I've tried to change the permissions of the directory with no results. What is wrong? Thank you

Do not modify the /opt/ros install trees. They contain shared binaries, already built for your system.

To add another package and build it from source, see the new package downloading question. In your case, specify /opt/ros/diamondback in place of /opt/ros/cturtle.

Thank you very much, I follow your suggestion and it works. I can't fix the problem using rosmake on the downloaded package, but I'd like to thanks also GeniusGeeko for the assistance!

This assumes you have "source /opt/ros/diamondback/setup.bash" added to the end of ~/.bashrc

  1. sudo gedit /opt/ros/diamondback/
  2. Change line
    export ROS_PACKAGE_PATH=/opt/ros/diamondback/stacks
    export ROS_PACKAGE_PATH=/opt/ros/diamondback/stacks:~/ros_packages
  3. mkdir ~/ros_packages && cd ~/ros_packages
  4. svn checkout
  5. restart terminal
  6. rosmake --rosdep-install gscam

Cheers, Bryce

I just love having all of my installed stacks in one neat place. Its just my opinion though.

Are you getting the same error?

Yes, it's always "mkdir: cannot create directory `build': Permission denied", nothing has changed

Try the top steps after you use, "sudo su"

As super user it can't recognize the command rosmake. I've also tried to reinstall all the binaries but I get always the mkdir error...

The permissions problem is a clue that you are going about it wrong.

But I don't know where's the problem. If I try to compile the stacks alredy present in the diamondback package everything it's ok, the problem it's when I try to add new package from svn. I've checked the enviroment variable and follow the tutorial, but the problem it's still there.
