You need to find where the libraries are installed and ensure that the -L library path flag is set correctly. Unfortunately I really don't know much about Linux installs or autoconf, but I do know what it's doing is creating a small C file which has a call to a function that should be in the library (glNewList in this case). It then compile and link that small program and if it works then library must have been found. From the list below it looks like you have Mesa installed so I can only assume it's not in a location the the linker looks by default, therefore the -L<dir path> option must be given to tell it where to look for the libMesaGL.0 (or libMesaGL.a sorry, as I said I don't know much about linux). e.g. it could be the library is /usr/local/lib/libMesaGL.sl so you would need to get -L /usr/local/lib in the the link flags (again, sorry don't know how to drive autoconf to do this). The configure script should generate a log (config.log?) that shows the small program is it trying to compile. To find the library you could do a find / -name "lib*Mesa*" (might take a while 8-) It could also be the library is named something else, (say) libOSMesaGL.a or something. No idea how to properly fix something like that, but as a last resort you could hand edit the configure.ac (might be configure.in) and change the name. Hopefully some help. Good luck, Stuart. cory barton wrote: > I wasn't sure how to get the SVN version, so I am trying to install > PLIB 1.8.5, but ./configure is failing. > > Here is the last bit of the ./configure output(everything before it is yes): > > checking for pthread_create in -lpthread... no > checking for glNewList in -lGL... no > checking for glNewList in -lMesaGL... no > configure: error: could not find working GL library > > I do have the following packages installed: > ii freeglut3 2.4.0-6 > OpenGL Utility Toolkit > ii freeglut3-dev 2.4.0-6 > OpenGL Utility Toolkit development files > ii glutg3 3.7-25 > the OpenGL Utility Toolkit > ii glutg3-dev 3.7-25 > the OpenGL Utility Toolkit development files > ii libgl1-mesa-dev 7.0.3~rc2-1ubuntu3 > A free implementation of the OpenGL API -- G > ii libgl1-mesa-dri 7.0.3~rc2-1ubuntu3 > A free implementation of the OpenGL API -- D > ii libgl1-mesa-glx 7.0.3~rc2-1ubuntu3 > A free implementation of the OpenGL API -- G > rc libglew1.4 1.4.0-1ubuntu1 > The OpenGL Extension Wrangler - runtime envi > ii libglew1.5 1.5.0dfsg1-3ubuntu1 > The OpenGL Extension Wrangler - runtime envi > ii libglib2.0-0 2.16.3-1ubuntu2 > The GLib library of C routines > ii libglib2.0-cil 2.12.0-2ubuntu3 > CLI binding for the GLib utility library 2.1 > ii libglibmm-2.4-1c2a 2.16.0-1 > C++ wrapper for the GLib toolkit (shared lib > ii libglu1-mesa 7.0.3~rc2-1ubuntu3 > The OpenGL utility library (GLU) > ii libglu1-mesa-dev 7.0.3~rc2-1ubuntu3 > The OpenGL utility library -- development fi > ii libglut3 3.7-25 > the OpenGL Utility Toolkit > ii libglut3-dev 3.7-25 > development libraries and headers for GLUT > ii xlibmesa-gl-dev 1:7.3+10ubuntu10 > transitional package for Debian etch > ii xorg-driver-fglrx > 1:7.1.0-8-3+2.6.24.13-18.41 Video driver for ATI graphics > accelerators > ii xscreensaver-gl 5.04-4ubuntu1 > GL(Mesa) screen hacks for xscreensaver > ii xserver-xorg-video-glint 1:1.1.1-8 > X.Org X server -- Glint display driver > > What am I missing?
