Brian,
Thanks for taking time to reply to my email about
Compiling Lesstif on Cygwin. Thanks for referring me
to the cygwin-xfree mailing list.
I've tried quite a few things since I posted the email
you answered.
I reinstalled the lesstif version you recommended and
verified the compiler string you suggested is what I use.
Having done those things, I get the following error:
undefined reference to '_XtVaAppInitialize'
Do you know what's happening?
Gary
Here is the program (the first motif program in the O'Reilly book):
#include <Xm/Xm.h>
#include <Xm/PushB.h>
main(argc, argv)
char *argv[];
{
Widget toplevel, button;
XtAppContext app;
void i_was_pushed();
XmString label;
toplevel = XtVaAppInitialize(&app, "Hello", NULL, 0,
&argc, argv, NULL, NULL);
label = XmStringCreateSimple("Push here to say hello");
button = XtVaCreateManagedWidget("pushme",
xmPushButtonWidgetClass, toplevel,
XmNlabelString, label,
NULL);
XmStringFree(label);
XtAddCallback(button, XmNactivateCallback, i_was_pushed, NULL);
XtRealizeWidget(toplevel);
XtAppMainLoop(app);
}
void
i_was_pushed(w, client_data, cbs)
Widget w;
XtPointer client_data;
XmPushButtonCallbackStruct *cbs;
{
printf("Hello Yourself!\n");
}
The compiler string:
gcc -I/usr/X11R6/include -L/usr/X11R6/lib \
-lXm -lXt -lX11 hello.c -o hello

lesstif-0.93.41-1 is the "supported" package available via the normal
Cygwin setup installer at www.cygwin.com. Please use it.

This is basic C compiler stuff. Add -I/usr/X11R6/include to the
compile line and -L/usr/X11R6/lib to the link line.
These sort of questions are probably better suited for
cygwin-xfree@cygwin.com.
