<DIV>Dear Jan,</DIV>
<DIV> </DIV>
<DIV>thanks for the pointer. I am using Gentoo Linux on all my servers and they
also have howtos about this topic. The warning is definitely an important one
though...</DIV></DIV>
<DIV style="FONT: 10pt Courier New; COLOR: #000000">I will first try to find a
version of Radiance where 3ds2mgf still worked and compare the sources, then I
will know if it's worth the effort. I am sure I have some old machine with gcc
3.* somewhere, I guess I will try that first.</DIV>

<DIV> </DIV>Dear Erwin,<BR><BR>I don't know if the gcc is really the
problem - but if yes, see below an instruction how to build an older gcc
version with a newer one. I use that for compiling esp-r- which also has
trouble with gcc4.xx.<BR><BR>Then you have two gcc versions in parallel. Be
careful while installing: you have to use the <I>make bootstrap </I>otherwise
you can destroy your system (if you install it as root it replaces the
existing libraries - I once destroyed my system with
that....) <BR>Before using programs compiled under gcc3.x, you have to set the
library path to the related lib-path ( export LD_LIBRARYPATH=/opt/gcc33/lib or
similar).<BR><BR>Good luck!<BR><BR>Jan<BR><BR>------------- Instruction to
build an gcc 3.3.6, using gcc4.xx ---------------------------<BR><BR>Get
gcc-core from from GCC Mirrors Page<BR><BR>Compiling GCC-3.3.6:<BR><BR>Untar
the source then configure with:<BR>./configure --prefix=/opt/gcc33
--program-suffix=-3.3<BR>WARNING: Do NOT configure it with the default prefix!
It is recommended to compile it with this prefix else you can damage your
system!<BR>Now compile it with make bootstrap and after that install it with
make install. <BR><BR><BR><BR><BR><BR><BR>Gregory J. Ward wrote:

<BR>Date: October 7, 2008 9:56:34 PM PDT <BR><BR>I have tried your patch
but it didn't change things really. Out of curiosity I compiled the
current head on a 32bit machine (also under Linux) and I get the exact
same behavior (using the original 3ds2mgf.c). <BR>So I finally tried an
older binary of 3ds2mgf (Radiance 3.6a) on the same system and this one
works just fine. Unfortunatly I dont have the sources anymore to see what
happens if I compile them <BR>Somehow I get a feeling it might have to do
