I'm trying to build MetaFont from the web2c-5.8a stuff with both SunView and X11 support. The executable I build doesn't work and dies with the message ld.so: Undefined symbol: __XtInherit Now, from reading this list, I understand you will get this message if you link against the Xt library when you don't need to. Unfortunately, I know (from nm) that I really do reference the Xt functions so I do need the Toolkit librbary. My order of libraries is "-lXt -lXext -lX11 -lsuntool -lsunwindow -lpixrect". My X11 is MIT X11.4.11 built from the MIT sources and patches/fixes. My current target (and compilation) machine is a Sun3 running SunOS4.1. Can anyone suggest another reason for this error message?

It seems I left out a crucial piece of information in my original message: I got the error while trying to build trapmf. It seems that the windowing code is commented out during construction of the TRAP version of MetaFont so I was, in fact, linking again the toolkit when my program was not using the toolkit. Doing so, on a Sun, causes the error message I saw, Moral: If ld.so (under SunOS) tells yuou that __XtInherit is an undefined symbol, you have probably linked against libXt when you don't need to do so (even when you think you do).

The same happend to me just one day ago. Static linking (-Bstatic) "solves" the problem. bernward Bernward Averwald X Computer Consult GmbH Brandenburger Str. 2 D-4030 Ratingen Germany

Well, if I'm not mistaken, and I have been MANY a time (grin), you might
want to try out compiling the program without the Xt/Xaw/Xmu libraries.
I tried compiling one of my programs by typing in:
cc -o myprog myprog.c -lXaw -lXt -lXmu -lX11 -O
and it worked without a hitch. But then, when I ran it, I got the same
message you did:
ld.so: Undefined symbol: __XtInherit
When I went back and compiled the program with:
cc -o myprog myprog.c -lX11 -O
it worked just fine. I wasn't using the Xt widgets, so I didn't need
the libraries. Hope this works!

The error typically occurs when you're linking with the shared Xt library without ever actually using it in the program. So either - try linking without -lXt - switch to using the X interface that actually uses libXt (METAFONT has two, one Xlib-based, the other Xt-based. the latter is recommended).
