I have traced and fixed my problem with dtpad crash on startup which
is I think similar issue to what you reported before and maybe now.
Some of the functions in libDtWidget (and I suppose other libraries to)
do not include proper Motif headers.
For example (what crashed by dtpad), lib/DtWidget/Editor.c
was missing these:
#include <Xm/LabelG.h>
#include <Xm/SeparatoG.h>
#include <Xm/PushBG.h>
#include <Xm/ToggleBG.h>
#include <Xm/RowColumn.h>
#include <Dt/HourGlass.h>
With 64 bit it may cause crash when interfacing with libXm
because (Widget) pointer returned is assumed to be (int)
when there is function prototype and therefore it gets
truncated to 32 bit.
My dtpad crashed because in Editor.c:4792
M_status_lineLabel(parent) = (Widget) XmCreateLabelGadget( container,
"lineLabel", al, ac);
The Widget pointer was truncated and it caused the crash later
in the code.
So the bad news is unless most of the compiler warnings are fixed
we will have trouble running some code on 64 bit systems.
I have fixed most of the DtWidget problems, once complete will post
the patch; but there are still other libraries waiting.
