Hi there!
Got stuck a little (Slackware 8.1).
Trying to compile esdl (esdl.sourceforge.net) library
(adds sdl/OpenGL functionality to erlang), the sorce does not come with
a configure script, just "make && make install".
The problem is, it stops with the following error:


/usr/i386-slackware-linux/bin/ld: cannot find -lGLU
collect2: ld returned 1 exit status
make[1]: *** [../priv/sdl_driver.so] Error 1


locate libGLU glu.h output is:
/usr/X11R6/lib/libGLU.so.1.3
/usr/X11R6/lib/libGLU.so
/usr/X11R6/lib/libGLU.so.1
/usr/X11R6/lib/libGLU.a
/usr/X11R6/include/GL/glu.h
/usr/local/include/GL/fglu.h #heck if I remember where this one came from

(so, it's present)

I have the /usr/X11R6/lib in my /etc/ld.so.conf
echo $LD_LIBRARY_PATH gives me "/lib/glut/:", default from /etc/profile, which
is wrong on my system, I don't have /lib/glut (installed libglut.so to
/usr/local/lib)
Also I am running an nVidia card and have OpenGL/SDL libraries installed
and working fine (shooting Quake2 at 1280x1024 )
(/usr/lib/libGL.so -> /usr/lib/libGL.so.1->/usr/lib/libGL.so.1.0.4363)


This is the second or third time I am running into the same thing (-lGLU).
Maybe someone had something similar || more familiar with ld || could point
me in the right direction.

Thanx in advance! -nabis

P.S. esdl nedded for Wings3d.

edit the Makefile and add "-L/usr/X11R6/lib" before -lGLU

Thank you ravage, I edited Makefile the way you said, it compiled,
with errors, some progress still...
I will try to figure it out myself, but just in case
a part of Makefile:
-------------------------------------------------------------------------+
OS_FLAG = unix

OGLDIR = /usr/X11R6

# Uncomment these if your opengl header is located in another directory than
# the usual $(OGLDIR)/include/GL/gl.h
#GL_INCLUDE_DIR = OpenGL
#USE_GL_INCLUDE_DIR = -DFULL_PATH_TO_GL_INCLUDE_DIR

GL_LIBS = -L$(OGLDIR)/lib -lGL -lGLU
GL_INCS = -I$(OGLDIR)/include/$(GL_INCLUDE_DIR)

SDL_LIBS = $(sh sdl-config --libs)
SDL_INCS = $(sh sdl-config --cflags)

LIBS = $(GL_LIBS) $(SDL_LIBS) -lm

CFLAGS = -g -O2 -funroll-loops -Wall -ffast-math -fpic \
-fomit-frame-pointer $(USE_GL_INCLUDE_DIR) -DSHM \
<snip> -DPTHREADS $(GL_INCS) $(SDL_INCS) $(ERL_INCS)
----------------------------------------------------------------------------+

The problem is that libGLU.so is in /usr/X11R6/lib and libGL.so in /usr/lib,
gl.h and glu.h are both in /usr/X11R6/include/GL.
Any advice?
