------- Additional comments from m...@openoffice.org Sat Feb 7 09:03:49 +0000 2009 ------- C++ code developed in Win32 systems is based on the ILP32 model, where int, long, and pointer types are 32 bits. UNIX systems follow the LP64 model, where long and pointer types are 64 bits, but ints remain 32 bits. For the (Windows) Application Binary Interface on x64, ILP is 32 bits : 32 bits : 64 bits. (Note this is different than the ILP for 64-bit Linux) So, before even beginning to move code over to the new platform, make sure you're not making assumptions about the width of these data primitives. also see: http://www.unix.org/version2/whatsnew/lp64_wp.html http://www.ibm.com/developerworks/aix/library/au-porting2/index.html http://developer.amd.com/documentation/articles/pages/372005120.aspx so a Windows 64bit edition will not just be a matter of recompiling the stuff for 64bit, there will be some more efforts in doing the review of the used data type and then following some QA work. The 32bit version of OpenOffice.org is running well on 64bit Windows and currently the most common use cases for Office productivity don't require the "advantages" of the 64bit model. I expect that some porting work will start once Windows x64 get broader installation basis. --------------------------------------------------------------------- Please do not reply to this automatically generated notification from Issue Tracker.
