Description (last modified by ryandesign (Ryan Carsten Schmidt))
I get the following error when I run /opt/local/bin/gitk on MacOS 12.7 (M1 ARM):
% /opt/local/bin/gitk application-specific initialization failed: no display name and no $DISPLAY environment variable Error in startup script: no display name and no $DISPLAY environment variable while executing "load /opt/local/lib/libtk8.6.dylib" ("package ifneeded Tk 8.6.14" script) invoked from within "package require Tk" (file "/opt/local/bin/gitk" line 10)
Not sure if this is related to #62988.

port install tk +quartz
did the job, thanks!
I was hoping to avoid running an X server on my Mac, I did that in the past for programs like Inkscape and always found it less than enjoyable to have a whole extra window system overlaid on the existing one.
For comparison, the Homebrew "git-gui" package also ships gitk, which seems to work fine without an X server installed or any special Tk options. Is there something fundamentally different about the Macports and Homebrew packages? Is the difference that they're possibly shipping a Quartz-enabled Tk build by default? They use the --enable-aqua=yes
build option: https://github.com/Homebrew/homebrew-core/blob/2e7221e9161b7d175c472e7044be9e53893b72ba/Formula/t/tcl-tk.rb#L89
Feel free to mark this as closed. However I would consider this a request to add a mention of the +quartz recommendation in the docs somewhere, for running Tk-based applications.

Sounds like you've already found your answer. Homebrew uses --enable-aqua=yes
unconditionally. We only use it if you request the +quartz variant.
We used to use +quartz by default in the tk port. It was changed to +x11 in 2015 for reasons explained in the commit message.
Moving to +quartz as the default for all ports is tracked in #60511.
Where in the documentation would be a good place to mention the +quartz variant, do you think? Anyone can submit improvements to the documentation, by the way.

…but users are expected to run port variants
to discover what variants are available for the ports they want to install.
% port variants tk tk has the variants: quartz: Enable native macOS graphics support * conflicts with x11 universal: Build for multiple architectures [+]x11: Enable X11 support * conflicts with quartz
Doesn't look like the same error message.
What X server do you have installed? What does
echo $DISPLAY
say?I'm assuming that you have an X server installed. If you don't, install ours by running
sudo port install xorg-server
and following the instructions it prints.
