解决“无法在..内定义成员函数……”的问题

Question

I have been struggling with this issue for a while and I would like to know a systematic way of figuring out why I might be getting this error. Apparently I have multiple components in my solution. I am getting this error when I attempt to build one of my components.

error: cannot define member function 'ImageFramework::ACE_Main::run_i' within 'ImageFramework'

 inline int ACE_Main::run_i (int argc, char *argv[])  \

A little background the component uses an external library called ace and the error lands me in an ace source file (which i am hesitant to touch as its not a part of my project). Which is something like this

#       define main \
ace_main_i (int, char *[]); \
ACE_BEGIN_VERSIONED_NAMESPACE_DECL \
ACE_Export int ace_os_main_i (ACE_Main_Base&, int, char *[]); \
class ACE_Main : public ACE_Main_Base {int run_i (int, char *[]);}; \
inline int ACE_Main::run_i (int argc, char *argv[])  \
{ \
  return ace_main_i (argc, argv); \
} \
ACE_END_VERSIONED_NAMESPACE_DECL \
int \
ACE_MAIN (int argc, char *argv[]) /* user's entry point, e.g., wmain */ \
{ \
  ACE_Main m; \
  return m.run (argc, argv); /*ace_os_main_i (m, argc, argv);   what the user calls "main" */ \
} \

int \
ace_main_i

#     endif /* ACE_WIN32 && ACE_USES_WCHAR */

#   else /* ACE_HAS_WINCE */

Anyways here is what I have tried for the above mentioned error message error so

 error: cannot define member function 'ImageFramework::ACE_Main::run_i' within 'ImageFramework'

I have looked through the ImagFramework class source .h and .cpp which has multiple include files. (Furthermore this class acts as a base class to many other classes) to see if an ace library header was included however I could not find any. I would appreciate suggestions on what might be a systematic approach on finding out what might be causing this issue . I might even be wrong interpreting this message. My understanding of this message is that possibly a method in the imageframework class or a method in its base class might be triggering the above part of the code. Please correct me if I am wrong ? Any suggestions ideas on this issue would be appreciated. Are there any other reasons why i might be getting this ?

Answer 1

It looks like ImageFramework class has a member called main . So the macro #define main ace_main_i ... expands and gives the error.
