HI
i want to use a sensor_msgs/MagneticField and sensor_msgs/Illuminance type message but my distribution (fuerte) don't have those types. (i checked the file sensor_msgs/msg) so i get the error ERROR: Cannot load message class for [sensor_msgs/Illuminance]. Are your messages built?
my messages are built, in fact i used from the same topic the sensor_msgs/imu
what should i do?
You could make an overlay of the sensor_msgs package using the groovy one in your fuerte build. Under the assumption that the older messages weren't changed, this should be OK, but everyone using this would need the same overlay.
The alternative is to define those messages yourself for your fuerte build (as a custom package)
Which is better depends on what you plan to do. If you want to connect to a groovy system, the first way would be better.
i have downloaded common_msgs and inside the sensor_msgs have pasted the 2 msgs that i want, i also have added them in the cmake but when i type rosmake i get that there is no makefile, i added a makefile, everything compiled but i still get the same message.
No, you just need to overlay them correctly, so that roscd sensor_msgs points to that. With define I meant: Make some package on your own. -- As to the wiki, I think that might just be wrong. If you go to the auto-generated code-api the messages aren't in groovy.
