If I try to compile a java code with "gcj mysource.java" I get the error: /usr/lib/gcc/i686-pc-cygwin/4.5.3/../../../libcygwin.a(libcmain.o):(.text+0xa9): undefined reference to `_WinMain@16' collect2: ld returned 1 exit status How can I solve the linker problem? (I have installed the newest version of Cygwin) Thanks Phil -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
