extern “C” did not work on its own.
you also need to remove “STATIC CONST”
then G++ stopped adding junk to the symbols.

The problem is that idltool adds “STATIC CONST” to a lot of stuff.

@LiveForIt
To get the original names of C++ functions and remove the "junk" you can use "c++filt symbol_name", for example "c++filt _ZL7libInitP7LibraryPvP9Interface".
Doesn't help for building libraries/devices using C++ code, but for example when you get a crash and have to demanding the names in a GrimReaper stack trace.

If I understand your problem correctly, I might try a solution that uses gcc to compile the required Amiga parts (C API) and g++ to compile the normal C++ code. And link using g++.

But you need to provide extern "C" glue to call C++ from C. It's normal.

Actually, I don’t know what the problem is, I think lib_res symbol has to be correct, even if I define it as extern “C”, it does not work. ramlib fails to read the library and load it into memory.

There should be no difference between compiling for example


struct Resident lib_res =

{

   ...

}

with gcc and compiling


extern "C"

{

   struct Resident lib_res =

   {

      ...

   }

}

with g++.

Same for functions/function prototypes.

it works now???

Not sure way it did not work before..

OT: Please double-check your _memset function, looks like it's setting the same address size times.

That's wrong and should be


for (ptr; size; size --) *ptr++ = n;

instead, and there is something else which can't work either:


INewlib = (NewLibIFace*) IExec->GetInterface( NULL /*NewLibBase*/,"main", 1, NULL);

But maybe that's the reason for now using an own (but wrong) _memset() function instead of the newlib.library bzero()?

Yeh.. might med a few bugs there just to make it compile.
