No problem

Well I don't think a summary sent to the list will be much use as most of the
people on the list have grass compiled. I thought of doing that as well but for
the reason mentioned above, decided not to. However, I have recently finished
compiling the floating point version of grass and have found many programming
errors. I plan to contact the keepers of the ftp site to see if I can submit an
updated version of the code with all the changes to replace the current
floating point code.

Yep, in the file $GIS/src/xgrass/display/Gmakefile there should be a line (line
10) which looks like

LIBS = $(BOGUS) $(XGDLIB) $(XGILIB) $(XXX) $(XPMLIB) $(BOGUS) $(YYY)

Change the line to be

LIBS = $(XGDLIB) $(XGILIB) $(XPMLIB) $(XXX) $(BOGUS) $(YYY)

That should now find XAllocColor

Yes I did but I have compiled the floating point version which I believe caused
some errors that you may not have encountered. Also, the "summary" of only the
xgrass stuff is over 1200 lines long because I included all warning and error
messages along with the fix I did for each. I'm picky when it comes to
compiling software and I like clean compiles (no warnings or errors). If you
really want the summary let me know and I'll put it on our ftp site.

Oh yes in the file $GIS/src/CMD/head/irix (I think it will be irix for you) the
XCFLAGS line should be as follows

XCFLAGS             = -D_NO_PROTO -DXM_1_1_BC

The -DXM_1_1_BC flag is needed for some backward compatibility issues. Let me
know if you have any problems with this.

Not at all. I'm more than happy to help.

Talk to you later.
