[Visualpython-users] CVS : typedef lock<mutex> lock is illegal

[Helmut J. <jar...@ig...>]

Hi,

I'm trying to compile vpython (CVS from today) but my gcc-4.3.3 bails
out :
../include/platlinux.h:27: error: declaration of 'typedef class visual::lock<visual::mutex> visual::mutex::lock'
../include/vthread.h:13: error: changes meaning of 'lock' from 'class visual::lock<visual::mutex>'

It doesn't seem possible to redefine 'lock'

Here a simple test case
#include <pthread.h>

template <class syncObject>
class lock 
{
 private:
	syncObject& obj;

 public:

	lock(syncObject& _obj) : obj(_obj) { _obj.sync_lock(); }
	
	~lock() { obj.sync_unlock(); }

 private:  // not implemented by design, to be noncopyable
	lock(const lock&);
	void operator=(const lock&);
};

class mutex 
{
	int count;
	pthread_mutex_t mtx;
  
 public:
	typedef lock<mutex> lock;

};


Has anybody solved that problem (perhaps by changing one of the
definitions of 'lock' to 'Lock' ) ?

Many thanks for a hint,
Helmut.
