Every time you guys make a release, there is a great deal of uncertainty
about whether virtualbox will compile or not on both windows x86 and x64. I
would love to test/use every single revision on svn, but you guys
*don't*respond to any build related questions and the ONLY real
support for
building virtualbox on windows is from non-oracle people on the forums.
So far, I was never able to simply do "svn update" and build without have to
track errors here and there and even modifying MS SDK/WDK. So I simply find
a version that works and document some workarounds for things that don't.
Then stick with that version until I have some time to deal with compiling
the next version of virtualbox.
My company have also been engaged in "talks" with Oracle to get licenses for
the ext-pack and maybe get some support, but that seems to be going no where
fast.
So if you really care that people test/use the latest VBOX and Oracle making
Money, do the following:
1- Make some decent build instructions that actually work
2- For gods sake! get some better sales people!!!!!
We very well appreciate your hard work, and are willing to pay you for it.
And its not my place to tell you what to do, but I believe a lot people
share my trouble.
