Building Radiance 3.5 on Tru64

radiance-general
1

Hello,

Has anyone any experience building Radiance 3.5 on Compaq tru64
systems ? I am trying this, and having some difficulty.

Initially, I was getting errors in the librt build due to conflicting
definitions of random functions. I have cut down the file random.h
to a minimum (included below) and now can get all the programs built
without errors (although warnings are quite numerous).

On running the oconv program on a file cut from the tutorial I get:

cropwell2$ /opt/pkg/radiance/bin/oconv room.rad
#?RADIANCE
/opt/pkg/radiance/bin/oconv room.rad
FORMAT=Radiance_octree

/opt/pkg/radiance/bin/oconv: fatal - bad # arguments for light "bright"

the room.rad is also included below. Any advice would be welcome.

regards,

Colin Bannister

Unless people feel strongly otherwise, I'm going to suggest we move this discussion to the radiance-dev list.

The error you get from oconv suggests that its getting confused about basic types, as the "bad # arguments" should not show up at all unless it thinks the light is a sphere or a face or something.

My first suggestion is that you try building from CVS head, which may be found on the radiance-online.org site under the "download Radiance" link. Download the current experimental bug-fix version, called radiance-HEAD.tgz, and compile from that. If you still get compile errors with the latest random.h, please forward them directly to me and I'll see what I can do. It's probably best to send me the entire output of makeall.
