Question

I’m modifying a C source file (libape-spidermonkey.c). I include a lib header file that uses some C++ features (such as, class definitions, STL string vector), so I have to compile libape-spidermonkey.c using g++ instead of gcc.

However, because of the type-checking in C++, I got a lot of errors (NOT warnings):

libape-spidermonkey.c: In function ‘JSBool ape_sm_raw_constructor(JSContext*, JSObject*, uintN, jsval*, jsval*)’:
libape-spidermonkey.c:2217:1: error: invalid conversion from ‘void*’ to ‘ape_sm_compiled*’

libape-spidermonkey.c:2646:31: warning: comparison between signed and unsigned integer expressions
libape-spidermonkey.c:2650:36: error: invalid conversion from ‘void*’ to ‘char*’

Is there any easy way to solve this issue? Like some macro magic?

Thanks.

Answer 1

Compile that file as a C file, rather than a C++ file. C and C++ objects can be linked together without problems.
