We at last have a 64-bit dual-cpu Opteron running 64 bit linux (Fedora
32 bit poplog works fine on that, as described here
Previously I reported as follows regarding the 64 bit poplog, ported by
Waldek Hebisch earlier this year.
I have now found that this problem occurs only when poplog is linked
with 64-bit OpenMotif. If poplog is linked without motif, then
everything seems to work fine, except that XVed lacks pull-down menus
and a scroll-bar.
I don't know if the problem will occur if 64bit Lesstif is used instead
Anyhow the latest package for poplog on AMD64 linked without motif is
available to be fetched, installed and run here
