[Gnash-dev] Cannot link new render handler

[Udo Giacomozzi]

Hi,

this is probably a dump question, but I fail adding
render_handler_tri.cpp to the source tree.

The source files are very simple:

--- render_handler_tri.h ---------------------------------
#ifndef GNASH_RENDER_HANDLER_TRI_H
#define GNASH_RENDER_HANDLER_TRI_H

#include "gnash.h"
#include "types.h"
#include "image.h"
#include "utility.h"
#include "log.h"

#include "render_handler.h"

namespace gnash
{

class triangulating_render_handler : public render_handler
{
public:

  virtual void testtesttest();

}

#endif // GNASH_RENDER_HANDLER_IMPL_H


--- render_handler_tri.cpp -------------------------------

#include "gnash.h"
#include "types.h"
#include "image.h"
#include "utility.h"
#include "log.h"
#include "render_handler.h"
#include "shape_character_def.h"
#include "generic_character.h"  

namespace gnash {

class triangulating_render_handler : public render_handler
{
public:


  virtual void testtesttest() {
    log_msg("hello");
  }

}; // class triangulating_render_handler

}  


-----------------------------------------------------------

I added the file to Makefile.am:
RENDER_SOURCES = render_handler_agg.cpp render_handler_tri.cpp
then run automake and config.

But then the linker fails:


g++ -g -O2 -march=pentium3 -W -Wall -Wcast-align -Wcast-qual -Wpointer-arith 
-Wreturn-type -o .libs/gnash gnash.o  /usr/lib/libpango-1.0.so

../backend/.libs/libgnashbackend.so: undefined reference to `typeinfo for 
gnash::triangulating_render_handler'
../backend/.libs/libgnashbackend.so: undefined reference to 
`gnash::triangulating_render_handler::testtesttest()'


The method can be found in libgnashbackend.so
         U _ZN5gnash28triangulating_render_handler12testtesttestEv
and in render_handler_agg.o (since it's the only class that derives
from it).
         U _ZN5gnash28triangulating_render_handler12testtesttestEv



What's wrong here?
