I've been having problems with building cow. I've tried this with OSX and ubuntu dapper, and have experienced the same problem, so it's probably a bug in the build process. $ ./configure > /dev/null ; grep -- -I system.mk MPINC = # -I. INCS = -I I have to change that 'INCS' line to read INCS = -I. for anything to compile properly, otherwise it consumes the next compile flag as an include directory... I'm using anon sourceforge cvs to compile from. -- Stephen Thorne Development Engineer
