Yes it is. OK thanks for the clarification.... So if I want to put the libpng12 in an image then do I need to do something like: # Add libpng to DEPENDS to get the recipe to build # Add libpng12 to IMAGE_INSTALL because that's what I want in the package DEPENDS += " libpng" IMAGE_INSTALL += " libpng12" _______________________________________________ Openembedded-devel mailing list [email protected] http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-devel
