To copy to clipboard, switch view to plain text mode 

What sounds very weird is not the code, it's the message outputted by gcc! AFAIK there is no need of any cast to convert T** to const T**... Looks like troubles are coming from your compiler...

I am aware of that, are there any guidelines/ideas, what could be wrong???

I guess it's the problem with g++ 3.3.6. Following program compiles without any problems on g++ 4.1.2:

void func( const unsigned char **c )
{
}
 
int main()
{
   unsigned char *a = 0;
   func( &a );
   return 0;
}

void func( const unsigned char **c )
{
}

int main()
{
   unsigned char *a = 0;
   func( &a );
   return 0;
}

while g++ 3.3.6 reports the same error as in libjingle code.

Where did you get 4.1.2 version? I cannot find it anywhere. I downloaded the latest version of gcc, same shit.

Where did you get 4.1.2 version?

It might be a snapshot, not an official release, but it's the default compiler in the Th release of PLD Linux (actually Th is still under development).

I downloaded the latest version of gcc, same shit.

Try g++ 3.3.5 or patch libjingle sources.

[MarkoSan]

I've downloaded tha patch file for libjingle, how do I now pach the libjingle source in the source tree?

See `man patch`.

In short: Make sure that the main directory of libjingle sources is the current one and type:

patch -p1 < /path/to/patch/something.patch

I've upgraded to gcc ver 4.1.1., now I got this shit:

I am desperate!!!!

Apply that patch or downgrade to gcc 3.3.5.
