Greetings:
I'm trying to compile the Teknocomposer software but have run into a
problem that Nick doesn't know what to do about (beyond suggesting I
update my compiler). Here's the failure point:

The specific code block looks like this:
/////////////////////////////////////////////////////////////////////////////
class AppSoundDriver : public SoundDriver
{
public:
AppSoundDriver(REAL sample_rate, int num_channels);
virtual ~AppSoundDriver();
// this is called to fill buffer with len samples
void Run(REAL * buffer, uint32 len);
void Start();
void Stop();
};
AppSoundDriver * theSoundDriver;
AppSoundDriver::AppSoundDriver(REAL sample_rate, int num_channels)
{
printf("Starting Sound Driver...\n");
#ifdef PORT_AUDIO_DRIVER
openPortAudio(this, sample_rate, num_channels);
#endif
#ifdef ALSA_DRIVER
openALSADriver(this, sample_rate, num_channels);
#endif
}
AppSoundDriver::~AppSoundDriver()
{
printf("Closing sound driver...\n");
#ifdef PORT_AUDIO_DRIVER
closePortAudio();
#endif
#ifdef ALSA_DRIVER
closeALSADriver();
#endif
}
//////////////////////////////////////////////////////////////////////
Nick's advice to upgrade my compiler is timely (I'm using GCC 2.96 from
RH 7.2) but unfortunately I can't make the switch right now. If there's
an obvious (or non-obvious) solution to my dilemma I'd be happy to hear
of it.
