Hi, We have one 64bit setup in our company. It was not used for few months, but in the summer we we built couple osg releases using it. In that time, it was just a matter of selecting target 64 bit VS environment, when Cmake was run for the very first time in OSG directory. This selection is also available as a result of Cmake "clear cache" command. Clearing cache will bring target selection dialog again. Look carefully - you should be able to find 64 bit VS 2005 target. Maybe new cmake has 64 bit 2008 as well
We ended up using VS 2005 Standard for 64 bit. VS 2005 Express does not offer 64 bit builds out of the box. Cmake won't also generate 64bit solution for VS 2005 Express. 64 bit in VS Express is theoretically possible with some hacking using Platform SDK compiler. But I attempted this path and give up due to some strange issues with compilation of stl and some predefined macros. Apparently Sdk compiler has to use Platform SDK headers and libs. It did not work well with Stl from VS 2005 express. So we ended up buing the cheapest commercial VS relases that alllowed to do this.

One of the things we do need is both is 32bit and x64 on windows, the Gent we have getting things upto speed cannot seem to find any thing to do 64 bit builds in the Cmake configs etc. ( Cmake is all new to him and I'm about the same ) I'm sort of asking this question blind as I'm not in a position to check things ( sorry), so as said possibly dumb/stupid question, But what do we need to do to get Cmake etc to throw out 64bit solutions for windozes as well as 32bit thanks G. __________________________________________________________ Gordon Tomlinson Email : [EMAIL PROTECTED] YIM/AIM : gordon3dBrit MSN IM : [EMAIL PROTECTED] Website : www.vis-sim.com www.gordontomlinson.com __________________________________________________________ "Self defence is not a function of learning tricks but is a function of how quickly and intensely one can arouse one's instinct for survival" -Master Tambo Tetsura
