[Gate-users] Install GATE in Mac os Mavericks

[Marc Chamberland]

Hi Pedro,

I'm not sure about your OGLS problem, but yes, the crash you experience with Qt is probably the same one I had.

Look at Jérôme's message that I linked to in my previous message. You need to add the following lines in the file Gate.cc (in the source code of Gate):

#ifdef __APPLE__
		/*
		 * If the program was started by double-clicking on the application bundle on Mac OS X
		 * rather than from the command-line, enable Qt and don't try to process other options;
		 * argv[1] contains a process serial number in the form -psn_0_1234567
		 * OS X <= 10.8 have a -psn_XXX argument given by the system
		 * OS X >= 10.9 does not have one, so we use the "TERM" environment variable
		 * to distinguish between launched by the Terminal or by the system.
		 */
		if ( ( (argc > 1) && (strncmp( argv[1], "-psn", 4 ) == 0) ) || getenv("TERM") == NULL ) {
			argc = 1;
			isQt = 1;
			break;
		}
#endif

In the current version of Gate 6.2 distributed on the website, those lines go just before lines 185-186 which are:

     // Getting the option
      c = getopt_long( argc, argv, "ha:", longOptions, &optionIndex );


Once you've added the lines above, save the file, then recompile Gate. Qt visualization should work again.


Marc
