Martin,

Generally speaking the errors will be emitted to stderr when they are
issued.  If stderr doesn't go anywhere in your case (perhaps a win32
gui app) then it might be prudent to install the "logging" error handler
to capture errors to a log.

eg.

    CPLSetConfigOption( "CPL_LOG", "C:\\cpl_errors.log" );
    CPLPushErrorHandler( CPLLoggingErrorHandler );

Best regards,
