[aspectc-user] Compiling an existing pure C project with AspectC++ using Eclipse or manually

I'm sorry, but it would take you a few hours/days of manually turning 8cc into
C++-compliant code before you can compile it with ac++.

The problem is that not every valid C program is also a valid C++ program. For
example, in C you can convert a 'void *'-typed object into a pointer of
arbitrary base type. In C++ an explicit type cast is required for doing that.
Furthermore, 8cc uses C11-specific keywords such as _Noreturn and C99-style
aggregate initialization. Therefore, the Clang-based frontend of ac++ generates
lots of error messages.

In theory, one could configure the parser of ac++ to be a pure C-parser.
However, this alone wouldn't help much, because the transformed code strongly
relies on C++ templates. One would end up with a mix of C11 and C++ code, which
couldn't be compiled by any compiler.

Best regards,

Olaf Spinczyk
