[Coin-discuss] cygwin build

Tue Aug 15 14:44:56 EDT 2006

One of my apps uses Concorde, which I cannot seem to get it to compile 
with the -mno-cygwin switch. I'd prefer the COIN default not use this 
flag - but having the option would be nice. Is there an easy way for me 
to shut this off for my COIN build? The old way, we had a 
Makefile.CYGWIN that I could change. What is the new way?

Thanks,
Matt
