Error with C backend

[docroger]

Hello José, me again...

With the last version afxnova (with tabs) : i cant compile with gcc :

error: '_ZTSN14AFX_IDISPATCH_E' undeclared here (not in a function); did you mean '_ZN14AFX_IDISPATCH_C1Ev'?
 3274 | static struct $8fb_RTTI$ _ZTSN7AFXNOVA16AFX_IDICTIONARY_E = { (void*)0ull, (char*)"N7AFXNOVA16AFX_IDICTIONARY_E", &_ZTSN14AFX_IDISPATCH_E };
      |                                                                                                                    ^~~~~~~~~~~~~~~~~~~~~~
      |                                                                                                                    _ZN14AFX_IDISPATCH_C1Ev

With GAS64 : no error.
My app is broken.

PS : if i comment include afxnova/cinifile.inc : the code compile fine with GCC...

Works in my computer. I don't know what this cryptic message means.

You can't compile what?

[docroger]

My app use AFXnova DDT + Cinifile : compile well with prec version AFXnova.

With the latest : compile with GAS64 but error with GCC.

If i comment then include cinifile on my app : compile with GCC.

Without Cinifile no problem.
The error message is linker message.

With the latest afxnova on github :

That's strange. I am also getting that same error when trying to compile with gcc. Hopefully it is not a Tiko Editor problem with the compiling of the source code. I will have to try compiling it with a different editor (or command line) just to be sure.

[José Roca]

Found the problem. Remove NAMESPACE AfxNova and END NAMESPACE in AfxScrRun.bi

[José Roca]

Never had tried gcc before. Optimizing for size reduces the size of the executable very much.

[Paul Squires]

Ah, that's good news that you found the cause of the problem!
