Which version of mesa will support the ARB / NV fragment program extensions? When will it be released? thanks. shankar __________________________________________________ Do you Yahoo!? HotJobs  Search new jobs daily now http://hotjobs.yahoo.com/

A more robust solution would be to do away with preprocessor tests altogether and let autoconf test directly for the presence of finite() or isfinite() at compile time. I don't know enough about autoconf to provide the required invocation for it. Come to think of it, I can use such invocation in some of my own projects. Perhaps someone else on this list can help in this regard.  Rouben Rostamian <rostamian@...>

It sounds good in principle, but in practice I find that it seldom works on IRIX, AIX, SunOS, etc. (even after installing gcc, gmake, etc). The Mesa bug database has many such reports. The libtool stuff is especially ugly. Personally, I never use the autoconf/automake stuff in Mesa. I use the oldstyle Makefiles and will continue to maintain them. Brian

 Original Message  From: "shankar ghosh" <shankarthe9th@...> > Which version of mesa will support the ARB / NV > fragment program extensions? When will it be released? > I cannot answer the question directly, but I am working on the ARB_vertex_program for Mesa (there might be others, but if so I haven't heard of them) which have several functions in common with ARB_fragment_program. Which means that I might (at least I want to) move on to implementing the fragment part when I'm done with the vertex part. Things are somewhat slowgoing though, since I have to use most of my time on a university project which have final deadline in 3 weeks. I hope to have something working by the end of November, but no guarantees. If all goes well I might have some working fragment code in February (wild guess), if not; .... Lars Ivar

Hi Brain I am glade at last someone got your attention!!!!! When it comes to HPUX platforms finite(x) and isfinite(x) is been a bug for long long time. I 've send you email with patch every time the new vesion of Mesa was out!!. I 've been porting Mesa for the HPUX Archive for long time now. I hope to see some change in future release of Mesa.

I generally don't ignore email sent to me. Brian
