<P><FONT SIZE=2>Thanks, Frank. I think that must be where it goes wrong.<BR>
<BR>
I tried to get an OSGeo userid (I used to have one, but it forgot me), but it won't let me. The form says my userid has been created, but it rejects it upon login. If I use the "forgotten password" functionality it doesn't recognise my email address.<BR>
<BR>
I don't think I'd know how to compile mapserver and mapscript from scratch (haven't tried it for a few years), but there may be someone here who can. I will investigate that.<BR>
<BR>
regards,<BR>

With some pointers from Howard, I found this segment of code in<BR>
bindColorAttribute() in maputil.c:<BR>
<BR>
attribute->red = atoi(tokens[0]);<BR>
attribute->blue = atoi(tokens[1]);<BR>
attribute->green = atoi(tokens[2]);<BR>
<BR>
<BR>
I think this is responsible. If you are building from source, try just<BR>
changing it to the more obvious organization. I'd also suggest you<BR>
file a bug in Trac on the issue we will see if there is a subtle reason<BR>
for this, or it's just a typo.<BR>
<BR>
To file bugs you need an OSGeo Userid. The pointer to get an osgeo<BR>
userid which you can use to login with is under the title "Important<BR>
Notice" on the <A HREF="http://trac.osgeo.org/mapserver">http://trac.osgeo.org/mapserver</A> page. The same userid<BR>
can be used for other OSGeo services like subversion, and other<BR>
trac instances (like GDAL's).<BR>
<BR>
Best regards,<BR>
