Help with link error (this time with gcc info)

Thu, 31 Oct 2002 18:42:37 -0800

I am trying to embed mozilla in an application. I am starting by writing a simple example. Everything compiles fine, however I get the following link error. The source and makefile are below. Any help would be appreciated.

Environment:

gcc-3.2
glibc-2.2.5
Gentoo Linux 1.4(RC1)

Error:
Main.o(.gnu.linkonce.d._ZTI14nsAFlatCString+0x8): undefined reference to `typeinfo for nsASingleFragmentCString'
collect2: ld returned 1 exit status
make: *** [htmlcontrol] Error 1



Main.cpp




#include <stdlib.h>



#include <nsEmbedAPI.h>

#include <nsDependentString.h>

#include <nsASingleFragmentString.h>

#include <nsAFlatString.h>



int main(int argc, char *argv[])

{

    char *mozBinPath = nsnull;       nsCOMPtr<nsILocalFile> binDir;   
    nsresult result = NS_NewNativeLocalFile(nsDependentCString(mozBinPath), PR_TRUE, getter_AddRefs(binDir));



  return EXIT_SUCCESS;

}
