Minimal cross-platform implementation of the Component Object Model (COM) runtime and Active Template Library (ATL).

Designed as a compatibility library to enable building of existing COM/ATL classes with clang or gcc for for Linux, Mac and mobile platforms. Developed due to lack of knowledge of any better alternatives.

Design goals:

• Support simple COM classes implemented in ATL.
• Support most automation-compatible types, so that the same COM classes can be directly accessed from C# and Python (using comtypes) on Windows without any language wrappers or proxy/stub DLLs for marshaling.
• Compatiblity with clang and gcc.
• Compatibility with Linux, Mac, iOS and Android.

Missing features:

• Complete COM or ATL support. Out-of-process mashaling is for instance not implemented.
• Wrapper-code-free access from C# and Python on non-Windows.
• Out-of-process marshalling on non-Windows.

Please contact the author if you're aware of any better alternative, and he'll be happy to scrap this project.
