I'm working on a project that uses a combination of c++, c and fortran to

compile correctly under cygwin (using gcc 3.4.4).
I'm calling:
g++ -mno-cygwin -Wl,--add-stdcall-alias
-I/cygdrive/c/Java/jdk1.5.0_07/include
-I/cygdrive/c/Java/jdk1.5.0_07/include/win32 -shared -o Samplers.dll <a
whole bunch of source files here> -lstdc++ -lg2c
/cygdrive/c/DOCUME~1/ben/LOCALS~1/Temp/ccWWbiIF.o:gengam.f(.text+0x5):
undefined reference to `_dgamdv_'
(plus others of similar form)
The '-mno-cygwin' flag trigggers the "cross-compiler" to MinGW. If you're
having problem with this switch, you should check with the MinGW folks
(http://www.mingw.org/), since you're really using their compiler, not
Cygwin's.
