RE: non-widget child "DropSiteManager" error (WAS: RE: Grace (xmgrace) 5.1.12-1 ... )

["Atwood, Robert C" <r dot atwood at imperial dot ac dot uk>]

As far as I can tell, it not only build static .a library files, but did
not create any shared .dll files. Is there another step needed to do
this? I will try to comprehend some parts of the script and see if I can
figure how to create the dll's or why I did not get them in the first
place.

At first I tried buildign the lesstif by manually runing ./configure and
make but this did not work.

This is a list all the files called Xm that got installed :
</usr/X11R6>$find . -name '*Xm\.*'
./lib/libXm.la
./lib/libXm.a
./include/Xm/Xm.h
Thanks again
Robert

The whole build is done in .build.

I believe this is a static lesstif lib.  And, AFAIK, a static lesstif
lib will not work now that Xt is a DLL.  I don't know why it is still in
the package.  I would think that lesstif-0.93.91-6.sh should be passing
--disable-static to configure and that would keep this from being
built/installed.

Do not use that lib.  Move it out of the way.  You should be linking
with libXm.dll.a, although -lXm should just do that.

That is because you are linking with the broken static lib.

Libtool may have taken care of this for you, although I don't know why
it isn't now.  Look in libXm.la.

See the following reference for some details:

Yep.  Don't use that one.

You will still need the debug build to find the dialog problem.  Look in
the <package>.sh script to figure out how to do one manually.  It isn't
that hard to dig through.
