Subject: ___getreent error when compiling OpenGL/SDL program using gcc
To: cygwin AT cygwin DOT com
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii

Hello,
 
I have been trying to compile a SDL/OpenGL program. 
The program works under linux, and I am able to get
single-file OpenGL/SDL programs to compile and run
with cygwin.  When linking multiple files however, I
get this strange errors:
 
gcc  -g   view3ds.o gl_video.o sdl_event.o sdl_video.o
object.o  -o view3ds -lgl
ut32 -lopengl32 -lGLU32 -lopengl32 `sdl-config
--cflags --libs` -lm
view3ds.o(.text+0x94): In function `resizeWindow':
/home/Bob/prog/sdl2/view3ds.c:37: undefined reference
to `_gluPerspective'
view3ds.o(.text+0x3ca): In function `DrawScene':
/home/Bob/prog/sdl2/view3ds.c:93: undefined reference
to `_gluErrorString'
view3ds.o(.text+0x3d2):/home/Bob/prog/sdl2/view3ds.c:94:
undefined reference to
`___getreent'
view3ds.o(.text+0x7a2): In function `main':
/home/Bob/prog/sdl2/view3ds.c:160: undefined reference
to `___getreent'
view3ds.o(.text+0x7dc):/home/Bob/prog/sdl2/view3ds.c:167:
undefined reference to
 `___getreent'
view3ds.o(.text+0x809):/home/Bob/prog/sdl2/view3ds.c:174:
undefined reference to
 `___getreent'
view3ds.o(.text+0x841):/home/Bob/prog/sdl2/view3ds.c:183:
undefined reference to
 `___getreent'

 
I am using gcc 3.3.1
 
I find it strange that functions such as
gluPerspective will compile/link fine in a single file
program, but fail to work in project with multiple
source files.
 
Anyone have any suggestions?
 
Thanks,
 
Bob
