Immediate seg fault when running ros node

Question

I am new to ROS and I followed the directions for creating/making/running ros packages, but I get an immediate seg fault.

Here is what i did:

1. cd ~/ros_workspace
2. roscreate-pkg begtut std_msgs rospy roscpp
3. rosmake begtut
4. created talker.cpp from the tutorials and saved to src
5. added rosbuild_add_executable(talker src/talker.cpp) to CMakelists.txt
6. make
7. run roscore
8. rosrun begtut talker

I get "Segmentation fault" written to the screen

What am I missing?

Did you verify that the code was copied completely correctly?

Answer 1

So I figured it out. Thanks for those who looked at my question. I looked at the core dump file and saw that it was crashing in the boost threads. I apparentlty have 2 boost libraries installed. I think the ros install put another one in my system.

I went ahead and removed this version, and rebuilt my program. Now it runs fine.

Thanks.
