I have a problem trying to build any single-engine versions of the examples or my own tests using v2.1.2beta. The application fails to start on any browser with an assertion failure;
“Assertion failed: CCApplication ctor”
It appears that something’s not quite working when the source files are packed together using ant+build.xml.
Also, as noted in another post, there’s some problems with setDesignResolutionSize (it’s used in the template folder/examples). I have to comment this out else the app doesn’t work correctly.
