geomview-x11 with AIX3.2
I just downloaded your latest source for geomview-x11 to use on our Sun (SunOS 4.1.3, Sparc2's and 10's) and IBM (AIX 3.2, 320H's and 375H). The programs compiled and linked with some minor warnings on both systems. I made no changes to the mk.rs6000 and mk.sun files. Everything works just fine on the Sun's, but the IBM's coredumped when we tried to display objects of any complexity. I debugged and determined that the alloca calls were failing. I read in the info pages on alloca and pragma that, when using alloca under AIX, you must either use the "#pragma alloca" directive or the -ma compiler switch. I think we have a fairly current version of AIX and the xlc compiler. I recompiled with the -ma switch and everything works just fine. There is probably some performance tradeoff here (the pragma directive may help speed), but the simple solution for me is to use the -ma switch. Perhaps you know of some other way around this problem? Thanks, - andy ========================================================================= | Andrew B.
