Compiling 5.1 on linux

[rgsouthall]

Hello.
I am trying to compile 5.1 on a 64bit Arch linux system but the get the following error for some of the binaries which then don't get compiled. It seems Version.c files end up with strings containing version, data, host name and user which gcc does not like.

Version.c:1:10: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘attribute’ before numeric constant
RADIANCE 5.1
^~~

Regards
Ryan

@rgsouthall @rpg777 Hello, I get the same error compiling 5.0:

Version.c:1:10: error: expected '=', ',', ';', 'asm' or '__attribute__' before numeric constant
 RADIANCE 5.0
          ^
Version.c:4:1: error: invalid suffix "f836a233c1" on integer constant
 40f836a233c1
 ^

It looks like file src/rt/Version.c is automatically generated at compilation time.

Should I consider the build to have failed If I get that error, or does it only indicate a minor problem that can be ignored for all intents and purposes, i.e. Radiance is ready to use?

Here are the errors I see in the console output:

There were some errors.

Thanks for adding the stdout. Discussion brewing on radiance-dev. Will reopen the issue pending a resolution to the version string macro.

I had the same error in Debian stretch. It is a missing dependency. The editor "ed" is not installed automatically as in former versions:
... ed - Version.c < verscript.ed /bin/sh: ed: command not found" ...

The workaround I was able to come up with was to manually create src/rt/Version.c. The file I made is a one liner: char VersionID[]="RADIANCE 5.2";
