[ros-users] serial_port package failing to compile

[Blaise Gassend]

It says "System Error: Permission denied", referring to
"/opt/ros/cturtle/stacks/serial_port/build/CMakeCache.txt". Is it
possible that you compiled as root, and are now trying to compile as
yourself? I would recommend looking at file permissions to fix this
problem.
