[sldev] SLDev Digest, Vol 27, Issue 45

[Boy Lane]

A couple of things to note here.

The current b160 sources were reportedly posted on 3dxviewer.com at 
22nd/23rd March. And they were backdated to 9th March to make them looking 
like they were in compliance earlier.

It is a current source tree that fits their binary, however Dale is right. 
They try to make it difficult to compile a working version and they 
obviously want to prevent that anyone builds a 3rd party viewer other then 
KirstenLee's that can connect to their grid. They have said that several 
times and actively block all other viewers and tools by some obscure 
undocumented protocol change. Perhaps it's indeed only the version string 
:).

What is missing in the source tree are a cmake file to include the OGRE SDK. 
That is mentioned in the 5 lines readme. What is also missing are some 
resources, icons if I remember correctly. Minor things and I don't think 
that was intentionally left out. GPL doesn't require to include libraries 
into a published source but as Dale wrote the required scripts to 
incorporated them (here cmake) should be there (GPL2 3.c)

I was able to build the 160 viewer by manually installing the libs (easiest 
way to do so is by copying them from KirstenLee's older b84 sources), adding 
the missing resources the compiler complained about and commenting out two 
"include (Ogre)" lines in indra/CMakeLists.txt and 
indra/newview/CMakeLists.txt.

It was successful and it could connect to OLG.

There was a lot of discussion about the whole issue in 
http://www.sluniverse.com/php/vb/other-grids-virtual-worlds/26798-openlifegrid-continues-violate-gpl.html 
Please refer to that for more details.
