Apologies but I now have a new problem (I am trying to compile the latest CVS on 64bit version of Ubuntu 6.06)
The ./configure throws up erros in
/home/ndm12/grass64cvs/grass61.cvs/lib/ogsf
/home/ndm12/grass64cvs/grass61.cvs/visualization/nviz
When I try the make file in ogsf I get the following:
..relocation R_X86_64_32 against `first_avcodec' can not be used when making a shared object; recompile with -fPIC
/usr/lib/libavcodec.a: could not read symbols: Bad value
collect2: ld returned 1 exit status
make: *** [/home/ndm12/grass64cvs/grass61.cvs/dist.x86_64-unknown-linux-gnu/lib/libgrass_ogsf.6.1.cvs.so] Error 1
Grass will run but not NVIZ (not a surprise I guess).
Is this a CVS problem or do I need to do something?
Once again help is appreciated.
For the record I abandoned RHEL (actually I trashed the install and cannot get it to reinstall!) and returned to Ubuntu which generally works out of the box.

I can think of several possible solutions to this:
1. Use "./configure ... --without-ffmpeg ..."
2. Remove $(FFMPEGLIB) from lib/ogsf/Makefile and add it to
visualization/nviz/src/Makefile instead.
3. Build libavcodec as a shared library.
4. Build libavcodec as a static library but compiled with the -fPIC switch.

Hi Glynn,
Very many thanks, I now have a working copy 
************************************************************************

I can think of several possible solutions to this:
1. Use "./configure ... --without-ffmpeg ..."
This did not make any difference. The compile gave the same errors.
2. Remove $(FFMPEGLIB) from lib/ogsf/Makefile and add it to
visualization/nviz/src/Makefile instead.
This appear to have worked a treat! Just aswell as I would have had to
do some reading in order to perform the following:
3. Build libavcodec as a shared library.
4. Build libavcodec as a static library but compiled with the -fPIC
switch.
************************************************************************

This is a very helpful list. Will I have to 'make' this change everytime
I update the CVS?
Hopefully most of my future questions will relate to the use of grass
and not its compilation.
Best wishes

If you re-run configure, you need to run "make clean" before
re-compiling.

If you don't need the ffmpeg option (which provides the ability to
record fly-throughs directly to AVI files, rather than writing out
individual frames then having to use a separate encoder), the easiest
option is to just not use the --with-ffmpeg option (it's disabled by
default).
If you need the ffmpeg option and don't want to recompile it, you may
occasionally need to re-fix the Makefiles. When you update a file from
CVS, any changes to the repository version are applied to the local
copy as a patch, so any changes to your local copy will normally be
preserved. However, if the changes affect the modified portion of the
files, you will get a conflict, and will have to fix the Makefiles
manually.
