Hi,

I am having some issues with the action quiz custom message. The file’s custom message .h is not being found. However rosmsg list | grep is showing that the message exists. This is throwing a fatal error when I catkin_make. Screenshots below.

I appear to have found the fix.

For anyone interested. I commented out the #include and the uses of the custom message. Then I ran catkin_make. Then I uncommented it. Perhaps the .h files are created upon catkin_make? Seems unusual it wouldn’t create that first before compiling the cpp file. However it appears to have fixed the issue.

SCRATCH THAT!

Still getting the error. Not sure why it compiled sucessfully once.

Any help?

Hi John!

The problem is with your CMakeList.txt file.
