Hi again:

I tried to work around the error in my previous email by simply commenting out the source line in question.

No I cannot get past the call to 'glut-create-window :

When I use the original code in function 'lesson-14 that provides a window title using uffi:with-cstring OpenMCL decides to die without even telling me or SLIME.

I then went on to call 'glut-create-window as in

(glut-create-window nil)

but that obviously also does not work because

"value NIL is not of the exptected type MACPTR".

While this is just a question of digging into the OpenMCL specifcs of UFFI and also finding out about MACPTRs in OpenMCL I thought it's better to check if you have a solution for this already.

See ya, guys.

Hi all:

I'm stuck. I tried to understand what SLIME, OpenMCL and the cl-opencl source want to tell me. Somehow this is beyond my ability to Just Get It.

Where I'm stuck:

Getting glut-functions.lisp to use function 'glut-set-option which apparently is not in Apple's GLUT.

Of course I had to make some changes to various sources:

Notably I found that OpenMCL does not need to use a CLOS package because this is already built-in and accessable in the CL-USER package. Hell, why is there no CLOS entry in the OpenMCL docs ?!

Ehem, Kenny, I found a

/* stencils */

in the gl-functions.lisp file. Where did that come from? I changed this to use #| and |# as comment delimiters. Well, now it's fixed ;-)

ImageMagick and FTGL also work now on Mac OS X for me. I also modified the Imakefile in the ftgl-int directory to build a dynamic library on OS X. So that's working also with the test program being available.

Back to what's not working

The error I get is:

Can't resolve foreign symbol "_glutSetOption"

For detailed info pls see the attached PDF file - a screen dump showing Emacs with a backtrace.

Also, I attached the files I changed in a tar file so you can follow my adaptions.

I used "nm" and "otool" on OS X to track down the glutSetOption thingy but with no luck.

So, my question is:

How did you do it ????

Thx for any help.

Cheers, Frank
