Compiling PBRT 1.03 under Ubuntu Gutsy

[mimhotep]

Hi everybody.
I'm trying to compile PBRT under Ubuntu 7.10, but with no result.
I followed this path:
- Installed build-essential and zlib-devel through Synaptic;
- manually installed IlmBase-1.0.1 and OpenEXR-1.40 using
./configure
make
make install
so OpenEXR is in /usr/local/include/OpenEXR and libs in /usr/local/
lib (I suppose, so no modifications are necessary to the makefile).
- launched make in pbrt dir.

Unfortunately I got this error message

Hi again.
I solved the problem myself.
Despite the error message, it wasn't anything about OpenEXR, but the
lack of some dependenciens on my machine.

I just installed "flex" and "bison" packages and everything worked.

Now I'm not able to run pbrt executable (bash: pbrt: command not
found), but this is another story.

Have you added the directory with the pbrt executable to your PATH
environment variable?

Thanks,

Thanks Matt.
Just forgot to post here about this, but I solved it on the very same
day by adding these lines to .bashrc file in my home dir (obviously,
paths are local to my linux installation).

export PBRT_SEARCHPATH=~/Documents/pbrt-1.03/bin
PATH=$PATH:~/Documents/pbrt-1.03/bin
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
export PATH LD_LIBRARY_PATH

It might be useful for other users, so I should have posted before :)

Cheers,
