Ok, here you have my feedback on the NEW-HOpenGL-1.01 pack (I think it would be called HOpenGL-1.02 to avoid misunderstanding... :) (1) The problem between glut.dll and glut32.dll was resolved. Now the "configure step" finds "-lglut32" rather than "-lglut", and when I run the Red Book examples (and my own examples also) I don't get bored by *foo.dll not found* anymore. [I would like to say that, when I modified aclocal.m4 to make this happens before (OLD-HOpenGL-1.01), I DID NOT run "autoconf". I just deleted config.cache and started the compiling process all over again... sorry for this, I think it would have worked if I've done the right thing.] (2) [not very important] Warning messages still appear during the "make step". (3) I still get the following exception when leaving (pressing ESC in the) the RedBook_HS examples: fatal error: GLUT_CBWindow_d7T5: uncaught exception (4) Now this really intrigued me: why (GHC-4.08-1 + HOpenGL-1.00) programs are significantly smaller than (GHC-5.02 + HOpenGL-1.01)? The file attached in this email (tst.hs), once compiled, has 120Kb with the previous versions of GHC+HOpenGL, but 492Kb (!) with the present versions. This is true also for the RedBook_HS examples. And, to make things worse, the new programs are also SLOWER than the old ones. I thought that migrating to GHC-5.02 would make things faster... (specially for my bitmap loader!) -- Andre
