Hello folks,<br><br>I recently tried to use the GDAL 1.9.0 API from multiple threads. However, they may arise a deadlock situation<br>where one thread hangs in the cpl_multithread.cpp CPLAcquireMutex function and others hang in the pj_acquire_lock() function of the proj.4 4.7.0 API blocking each other.<br>The methods that set the locks seem to be the<br><br>int Initialize( OGRSpatialReference *poSource, <br> OGRSpatialReference *poTarget );<br> virtual int TransformEx( int nCount, <br> double *x, double *y, double *z = NULL,<br> int *panSuccess = NULL );<br><br>methods of ogrct.cpp.<br><br>Not using the methods prevents a deadlock.<br><br>Do you know about this?<br><br>Thanks for your attention!<br> </div></body>
