I thought it was only necessary to define UNICODE. _UNICODE seems like it ought to be a compiler-internals sort of thing. (ANSI reserves all identifiers beginning with _ for the compiler/library's internal use) > It compiles, but > when linking I get the error: > main.c: undefined reference to `_WinMain AT 16' I notice you're using gcc to both compile and link your C++ file. Does using g++ instead of gcc for both stages help any? cheers, DaveK -- Can't think of a witty .sigline today.... -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
