I use Cygwin with g++ for compiling my source codes and on some codes I
get the error:

/usr/lib/gcc/i686-pc-cygwin/4.5.3/../../../libcygwin.a(libcmain.o):(.text+0xa9):

undefined reference to `_WinMain@16'
[snip]

That means the linking is being done for a GUI application.  I guess you
wanted to build a console application, so you should learn what these
options for the linker mean:

-Wl,-subsystem,console
-Wl,-subsystem,windows

There are equivalent options used with the compiler g++, I think they are:

-mconsole
-mwindows

Yes I would build a console application (or a shared library, I can build the library).


I have tried both commands -mconsole and -Wl,-subsystem,console but the error
is created again. Should I rebuild my libraries with the -mconsole option, at the time
I have build them only with configure, make, make install?


Thanks

Phil
