The ENABLE_BOX2D/ENABLE_CHIPMUNK defines were previously
hardcoded in the Makefiles. Now you get chipmunk by default
on both platforms and can enble Box2D by setting USE_BOX2D in
your environment.
Also remove erroneous -D__CC_PLATFORM_FILEUTILS_CPP__ and
-D__CC_PLATFORM_IMAGE_CPP__ from linux Makefiles. These should
never be defined globally like this.
This change makes several fundamental improvements to the linux
build system:
- Remove duplication: a lot of the common make logic is now in
a central shared makefile: cocos2dx/proj.linux/cocos2dx.mk
- Quiet by default: unless you specify V=1 on the commandline
the output is now very clean and quiet.
- Dependencies: gcc's automatic dependancy generation is now
used (-MMD). This means that if you change a header file
then all the object that depend on it now get rebuilt.
- Don't store objects in the source tree: previously object
files were stored alongside the sources, which meant that
debug and release object clobbered each other which leads
to confusion and lots of unnecessary rebuilding.Q
- Library dependencies: each binary now depends on the libraries
it links aginst. This means that if the cocos2dx library
changes then all examples will get re-linked.
- Top level Makefile: there is now a top level Makefile that
can be shared/used by any platform the uses make as the
build system (for example NaCl). Everything can be built
by simply running 'make' at the top level. e.g:
make DEBUG=1
make DEBUG=1 clean
