Hi. I'm working on a graphics project on an sgi, and have been
trying to use C++ (AT&T, until I build g++) for a system that works with
the 4sight graphics calls.
It's not working.
Assuming that I have a "normal" set-up, I took the program
ocatahedron, found in ~4Dgifts/examples/glpg/ch02/octahedron.c, which works
fine when compiled with cc and the required libraries, and compiled it with
CC (the C++ compiler). I get a blank window, and "ERROR #4 ortho:
ERR_BADWINDOW" on my tty. I'm assuming that this is a bad thing, since
I don't know where documentation for error messages goes.
I snagged the C file, translated by cfront, did some sed'ing
to minimize the differences between the two files, commented out the
call to _main(), compiled with cc, and the problem is still there.
As far as I can tell, there aren't any differences between the
two files. I put absolute paths in the #includes, to make sure the
same headers were getting included, and such, changed the variables
back to the way they were originally, and as far as I can tell, the
only differences between the original main(), and the cfronted main()
is tabs, and resolved macros. I still get errors and a blank window.
Help? Does anyone have C++ code using gl calls which works?

It's a parameter passing problem. To use the GL with ATT C++, compile your source with (at least) the following compilation flags : +a1 -prototypes See the manual pages for the meaning of these flags. -- Robert van Liere -------------------------------------------------- Robert van Liere, Department of Interactive Systems, Center for Mathematics and Computer Science (CWI) Kruislaan 413, 1098 SJ Amsterdam, The Netherlands email: robertl@cwi.nl | tel: +31-20-592-4053 | fax: +31-20-592-4199
