Just started using 13.12 on my new Win 8.1 machine. When I compile the Bullet physics static lib, one of the four .a files is smaller than it was when I compiled with 12.11 and no longer works. All compiler messages are exactly the same - there are some warnings, but they are the same warnings as in the previous version.
I looked at the 13.12 change log, both short and long versions, and the closest I can come to an answer is the following entry:
* Make the gcc compiler be a bit more robust, when making static libraries (by Alpha)
That's a bit vague, but I have to wonder if it has something to do with the issue I'm having. Is there some way to uncheck recent compiler changes to see if it makes a difference?
