Yah! I've found the problem with the strange interactor problems of
the up and down arrows, etc. not working. It is not Lesstif and it is
not DX. It is the use of the trunc() function. This is not working on
my LinuxPPC machine. I have notified the LinuxPPC dev list and we'll
see if anybody can provide an explanation. If anybody else is having
problems with interactors not going up and down, etc. Try the
following little piece of code.
cat > trunc1.c <<EOF
#include <math.h>
int main() {
double a = -1.5;
double b = 1.5;
printf("trunc(a): %f\n", trunc(a));
printf("trunc(b): %f\n", trucn(b));
}
EOF
gcc trunc1.c -lm
a.out
If you get:
-1
1
Then you're okay and your interactors should work fine.
If you don't, then there is a problem with your math librarie's trunc
function. The fix would be to edit include/dxconfig.h and change the
HAVE_TRUNC line.
Is anybody else, other than LinuxPPC users seeing this behavior?
Thanks,
David
Okay, now that the easy stuff is out of the way, I guess I roll up my sleeves
and dig in :) Does anyone else see this strange behaviour with the
interactors?? Especially on a different platform. Or better yet, does anyone
see the correct behavior with a similar setup?? I'm referring mainly to the
interactor problems. I can see the geometry problems, and the core dumps, I
just haven't located the code that is causing it yet.
