I just got the tip and built the release version with Visual Studio 2010. The static library size, optimized for speed, is about 148MB. Optimizing for size produces a library of 149MB. For comparison, the debug version is 105MB.
I have a few other versions of Juce on my local machine and have tried building them. Invariably the release build is much larger than the Debug - typically 2 to 8 times the size. Visual Studio 2008 tends to produce equally large or larger builds.
Any idea what is going on there - release builds are normally much smaller than debug builds are they not?
