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>]

Update: by adding absolute paths to the missing libraries, I can get it
to compile,but now I get 

Error: attempt to add non-widget child "DropSiteManager" to parent
"xmgrace" which supports only widgets 


I have scanned the mailing list archive , and notice this problem
mentioned a few times with other software, eg DDD,  but I cannot find
any resolution to this problem mentioned. 
Any pointers/ redirections to an example I haven't found yet?

Thanks

Robert

Thanks again Harold -- This is getting to be a steadily decreasing
priority for me so don't rush to solve my problems at the expense of
those interviews. I can easily transfer the data to a Linux box and use
my patched Grace from there to get the tick marks -- at this point the
only reason to pursue this is to learn how, maybe I can even locate the
bug ( with a little help) ... 
I imagine that several other people also know the answers to these
questions as they are getting more general. I have had no problem doing
the same things on a Linux box, so it seems that it is the differences
between Linux (Red Hat 9, Red Hat 8, and Slackware 8.1) and Cygwin that
are messing me up.

I have those, but I cannot figure out how to get Configure to pick them
up. That is, I can compile the little test routine (as used by configure
to test the M*tif installation)  from the command line by including all
the -l flags for these libraries directly but grace<version>/configure
always fails because it is not including those flags.  ( I figured this
out since last time I posted here...the libraries were all
there,somewhere, just not referenced by -l flags ) 
-lXft -lfontconfig -lXrender in addition to those mentioned by default

I tried adding them in the environment variable LDFLAGS but that didn't
work either -- possibly they are in the wrong order. The LDFLAGS seems
to get put before the -I flags and before the other libraries. 

Is there some cygwin equvalent of ldconfig or ld.so.conf that I am
missing out here?  Or does the grace-<version>/configure script need
some changes to use a compiled LessTif instead of packaged binaries?
(this is what I will probably try next) 

I have had some confusion in the past about this, on Cygwin certain
libraries getting automatically referenced .. when does a library not
explicitly referenced by a -l flag get automatically referenced?

Robert,

You need at least the following packages to build grace and lesstif:

fontconfig
libfontconfig1
libfontconfig-devel

XFree86-prog
