Can't generate package for ros/fuerte/stacks/geometry/tf #17

Closed rgleichman closed 10 years ago

rgleichman commented 10 years ago

When I create a roshask package that depends on tf, and then run roshask dep, it prints out

roshask: Building messages for tf failed

My guess as to what's going wrong is that the file name tfMessage.msg begins with a lower case letter. This means that roshask generates tfMessage.hs, but the module name is Ros.Tf.TfMessage.

Your guess looks reasonable. Can you see if fixing it works, and, if so, open a pull request?

The relevant code is here: https://github.com/acowley/roshask/blob/dev/src/executable/PkgBuilder.hs#L130

See #18. It does not fully solve this issue since src/executable/Storable.hs still needs to be fixed.

See #19.
