Re: [fpc-pascal] C++ Name Mangling
One thing that just came to me is writting a c wrapper, but don´t put it on a DLL. Instead compile it into a object files, and link them. This way I have the portability of a c wrapper, but I don´t need external DLLs =) -- Felipe Monteiro de Carvalho ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

The effort is larger, but you really do get a more stable and portable solution. It doesn't tie you to a specific language too, so should someone want to use another language (?what I don't know?) they could still use your wrapper. You might even find some one would *pay* you to use it. You never know ;-) ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
[fpc-pascal] C++ Name Mangling
Hello,
Does anyone know a good way to find out the name of a exported method on C++
I am trying to link to C++ from Symbian OS. The method is declared like this:
class User : public UserHeap
{
public:
.
IMPORT_C static TInt InfoPrint(const TDesC aDes);
Normally I would guess it´s:
_ZN4User2InfoPrintEc
Or something similar. But it doesn´t work.
Any other ideas? I tryed to open the .lib file with a HEX editor to
search for _ZN, or other strings that would reveal the mangled name,
but it was futile.
thanks a lot,
Felipe
PS: My God, it´s a headache to link to c++

Not that C++ name mangling differs per compiler and per compiler version. Depending on what compiler the Symbian SDK uses, Valgrind code migth not be useable at all.

Re: [fpc-pascal] C++ Name Mangling
Ok folks, I made this question on the Symbian forum and got an answer =) One can use the Linker to create a dump file with all exported names. The command is the following: mwldsym2 -S -show names,verbose C:\Programas\Symbian\UIQ3SDK\epoc32\release\winscw\udeb\euser.lib And the function I was looking for is called: [EMAIL PROTECTED]@@SAHABVTDesC16@@@Z Bizarre, neh? Now that name isn´t a valid identifier for GNU Assembler ... but I should probably ask about that on a GNU As group. thanks a lot, -- Felipe Monteiro de Carvalho ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
