Error compiling package with custom messages

Hello, everyone,

I'm having some difficulty compiling a package that I've created with custom message.

When I run cmake . at the head of that package's directory, I get the error

 Assertion failed: file
 does not exist.  Message: message file not found

inside of the msg directory in my package, I have a file titled data_logger_measurement.msg but indeed, the file in question, which is the .h file, does not exist in that msg directory.

Isn't this message auto-generated?

Oddly enough, I have been able to run this package before, and I'm slightly convinced that it may be an issue with how my workspace is setup.

Many thanks in advance!

The header files for messages are autogenerated.


If you use catkin, also see: See

Aha! It was my fault after all! In my CMakeLists.txt for that package under the add_message_files section, I mislabeled my extension with a *.h extension instead of a *.msg extension. Thanks for the hand, though!
