I do not have the full error log, but perhaps someone could update the ticket with that.

Surely you've just linked to the full error log (which I posted on answers.ros.org) in that very post? i.e. http://pastie.org/pastes/6368348/text

@alexreg Most of the relavent error is in my link, but rosmake truncates errors, you would need to post the full build log from the log file which rosmake references.

This uses a non-standard C++ extension that clang doesn't support (a variable-length array of QPoint, which is a class). You can fix this by using a vector or making step_count a constant expression.

Ah right. Thanks for that! Hopefully this can be fixed soon. :-)
