The error I'm getting now is:
----------------------------
/usr/lib/gcc-lib/i686-pc-cygwin/3.3.3/libgcc.a(_chkstk.o)(.text+0x0):
multiple definition of `__alloca'

/usr/lib/libcygwin.a(d000085.o)(.text+0x0): first defined here

/usr/lib/gcc-lib/i686-pc-cygwin/3.3.3/libgcc.a(_eprintf.o)(.text+0x0):
multiple definition of `___eprintf'

/usr/lib/libcygwin.a(d000027.o)(.text+0x0): first defined here

---------------------------------

From the build command:

-------------------------

g++ -shared -nodefaultlibs -o
libInventor.dll -Wl,--out-implib=libInventor.dll.a \

-Wl,--export-all-symbols -Wl,--enable-auto-import -Wl,--whole-archive
libInventor.a \

-WL,--no-whole-archive -L/usr/lib -L/usr/lib/gcc-lib/i686-pc-cygwin/3.3.3 -L
/usr/X11R6/lib -L/usr/lib/w32api -L../libimage -L../libFL/src \

-ljpeg.dll -limage -lFL -lX11.dll -lfltk_gl.dll -lGLU.dll -lGL.dll -liconv.d
ll \

-lfreetype.dll -lcygwin -lstdc++ -lasprintf -lz -lkernel32 -lgcc

-----------------------------

I'm using nodefaultlibs because I had a problem linking before where I was
getting lots of multiple definition errors from essentially the same
library.  Using nodefaultlibs and linking all the libs I need by hand has
fixed all those, but I have those last 2 multiple definition errors.  Is
there any way to link libcygwin and libgcc without getting multiple
definitions of ___eprintf and __alloca?  It seems bizarre that those 2 would
conflict.  Maybe there's a command line option that I need to be using in my
build command.



Thank You

Judd
