-- About this library -- This library consists of the portion of EASTL which has been made open source through the EAWebKit distribution. EA has made these files available in zip format at http://gpl.ea.com . The purpose of this github project is to serve up these files in a more convenient way. This project isn't affiliated or endorsed by EA. EASTL is an STL replacement that is optimized for games. To learn more about EASTL, go here: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2271.html If you're just browsing, then most of the good stuff is under include/EASTL/ These files are only *part* of the actual EASTL library. According to Paul Pedriana, only 50-60% of EASTL is officially published; the remainder may be published sometime in the future. There's also a large suite of unit tests and benchmarks which are not yet published. -- Usage -- Add the 'include' directory to your include path, and the contents of 'src' to your project's source files. Alternatively, you can compile the 'src' files into a shared library and link against that. At minimum, you'll need to implement a default allocator function, since this is deliberately left unimplemented in EASTL. Here's the simplest code that will work: void* operator new[](size_t size, const char* pName, int flags, unsigned debugFlags, const char* file, int line) { return malloc(size); } void* operator new[](size_t size, size_t alignment, size_t alignmentOffset, const char* pName, int flags, unsigned debugFlags, const char* file, int line) { // doesn't support alignment return malloc(size); } Another function left unimplemented is Vsnprintf8, which can be as simple as: int Vsnprintf8(char8_t* pDestination, size_t n, const char8_t* pFormat, va_list arguments) { #ifdef _MSC_VER return _vsnprintf(pDestination, n, pFormat, arguments); #else return vsnprintf(pDestination, n, pFormat, arguments); #endif } There is also a wealth of compiler flags to choose from, refer to the file include/EASTL/internal/config.h to see what settings are available. For your debug builds, make sure to use the _DEBUG preprocessor flag, as this will enable many appropriate settings in EASTL. Alternatively, you could enable EA_DEBUG or EASTL_DEBUG for similar effect. For more documentation, you'll have to read the source code. :)
