I'm sorry for such question, but I can't find out how to build the cl-opengl.
Previously I've built cl-sdl and it was fun, but the project seem to be abandoned and I want to switch to cl-opengl. Unfortunately, I do not see any instructions on building the cl-opengl. :(
I tried to build it in the following way:
1. Installed rt and cffi. I use Gentoo, so I emerged them.
2. Then I built them by running SBCL and running commands like
(asdf:oos 'asdf:load-op 'cffi)
in /usr/share/common-lisp/systems
Everything was built without problems.
3. Then I downloaded the cl-opengl sources from the darcs repository at http://common-lisp.net/project/cl-opengl/darcs/cl-opengl/
4. I noticed that the Makefile has only "clean" target which was strange.
5. Then I tried to build the cl-opengl by running
(asdf:oos 'asdf:load-op 'cl-opengl)
Everything went fine.
6. But when I tried to compile the rest (examples, etc.) I experienced a strange problem. Running (asdf:oos 'asdf:load-op 'cl-glut-examples) lead to the following error:
---- debugger invoked on a LOAD-FOREIGN-LIBRARY-ERROR: Unable to load any of the alternatives: ("libglut.so" "libglut.so.3")
Type HELP for debugger help, or (SB-EXT:QUIT) to exit from SBCL.
restarts (invokable by number or by possibly-abbreviated name): 0: [RETRY ] Try loading the foreign library again. 1: [USE-VALUE] Use another library instead. 2: [RETRY ] Retry performing #<ASDF:LOAD-OP NIL {AC1AE89}> on #<ASDF:CL-SOURCE-FILE "library" {ABAE199}>. 3: [ACCEPT ] Continue, treating #<ASDF:LOAD-OP NIL {AC1AE89}> on #<ASDF:CL-SOURCE-FILE "library" {ABAE199}> as having been successful. 4: [ABORT ] Exit debugger, returning to top level.
(CFFI::HANDLE-LOAD-FOREIGN-LIBRARY-ERROR (:OR "libglut.so" "libglut.so.3") "Unable to load any of the alternatives:~% ~S" ("libglut.so" "libglut.so.3")) ----
I do not understand, how could it be. My system does contain libglut.so and libglut.so.3 in /usr/lib. And different opengl examples compile with it. Of course, It can be a problem with CFFI, but the CFFI was built without any errors (including CFFI tests).
Please, let me know if you have any information on how to fix this problem. I feel that my current LISP experience is not strong enough to fix the problem alone.
Thank you beforehand, rtvd
