Hi; I'm forwarding the email reply from the GNU ddd mailing list. GNU ddd is not compatible with xQuartz (?)
Thanks, Ken Wolcott ---------- Forwarded message --------- From: Eickeler, Stefan <stefan.eicke...@iais.fraunhofer.de> Date: Sun, Apr 16, 2023 at 5:39 AM Subject: DDD 3.3.12 (arm-apple-darwin22.4.0) gets Xt error (installed from source via MacPorts) To: kennethwolc...@gmail.com <kennethwolc...@gmail.com> Cc: Michael Eager <ea...@eagercon.com> Hi Ken, the error message is generated by XQuarz. It seems to be an incompatibility of DDD and XQuarz during the initialization phase of the GUI. You can try the new release 3.4 of DDD. We did a complete cleanup of the build process. Perhaps it works better with XQuarz, but we did only minor changes to the initialization phase. http://alpha.gnu.org/gnu/ddd/ddd-3.4.0-rc2.tar.gz Best regards, Stefan
