Re: [Paparazzi-devel] possible bug when using the cam files

[Pascal Brisset]

Hi Chris,

the problem is linked to a var/include/cam.h file which has been wrongly 
generated from the cam.xml settings file.

Please
- update from the subversion server, at least ./Makefile.ac: svn update 
Makefile.ac
- clean var/include : rm -fr var/include
- regenerate a proper var/include: make
- select basic.xml AND cam.xml for your settings
and you should be able to compile a simulator with the cam code (it 
works with slicer1.xml)

--Pascal
