Thanks to Hamish and Glynn for the suggestion to recompile d.colormode from grass 5 in grass6.
Yes hamish, I first tried with the binary from grass 5 - ooops. :-o
Recompiling does work with no changes to the code and a small change to the makefiles and this overcomes the problems of having only a 256 colour display card.
I think that is a porting error, not a code error. d.colormode just
calls R_color_table_float() which is still alive in the raster library.Did you just copy over the binary from GRASS 5? (ooops - yes!)
Try copying over source code into grass6 source tree, plagiarize the
directory structure and Makefile from say d.colors, and run make.d.colormode should be able to compiled for 6.x without changes. It
just needs someone to add it.
