#105 Dia not starting under Mac OS X El Capitan (10.11.1)

[Kai Schwarz]

Dia Version is 0.97.2-7 installed via Homebrew Cask dia. Have installed XQuartz 2.7.8 via Homebrew Cask too.

If I try to run dia it crashes. If I run it from commandline the following output is created:

Warning: AppleCollationOrder setting not found, using AppleLocale.
Setting Language: en.UTF8
dyld: Library not loaded: @executable_path/../lib/dia/libdia.dylib
  Referenced from: /Users/[username]/Applications/Dia.app/Contents/Resources/bin/dia-bin
  Reason: image not found
[1]    13492 trace trap  ./dia

The Mac OS X error report has the following information:

Exception Type:        EXC_BREAKPOINT (SIGTRAP)

Hope someone knows what is going on here.
Thank you for your time.

I am seeing the same issue. Homebrew, El Capitan, XQuartz 2.7.8, Dia 0.97.2-7.

Note that the unloadable library is being sought at @executable_path/../lib/dia/libdia.dylib.

The distribution does not have a lib/dia/libdia.dylib. There is lib/libdia.dylib and dia/libdia.dylib.

I will be happy to provide any further assistance.

I can confirm that the recent DIA version does not start if you upgrade to El Capitan. Before DIA was working as intended.

This solution is working for me:

[Wolf Kuerschner]

I can confirm that DIA starts again if you add

export DISPLAY=:0

after line 39 of the DIA app.

Let's see how stable the program will be.

Does not work for me on macOS Sierra Version 10.12.2, XQuartz 2.7.11:

Seems I was using a broken version (from homebrew). Downloading the latest 0.97.2 direct seems to work without any changes at all.

[Mac OS 10.13.2, with Xquartz 2.7.9, Dia-0.97.2-7.dmg]
I can't run Dia via its icon. To run it from the terminal, I first need to 'export DISPLAY=:0' before running /Applications/Dia.app/Content/Resources/bin/dia

[Nap]

To run it from the icon in LaunchPad, the bin/dia script needs to be modified to export DISPLAY=:0 before the test in line 27.
The reason for the failure seems to be due to the fact that $DISPLAY already contains a value; on my system it is: /private/tmp/com.apple.launchd.ltexsnZtF4/org.macosforge.xquartz:0.

[Nap]

In either case, there is no DIA icon in the Launch Bar while DIA is running. Though there is an X11 icon.

[Nap]

I upgraded my Xquartz 2.7.11, and now I have a Dia icon, but it 'bounces' the entire time that Dia is open.

[Alexander Abreu]

Working for me and would work on any Mac OS X version; just follow these steps:

1. Download both files: Dia and XQuartz.
2. Install both
   - Do not run any of them.
3. Go to Applications/Dia/Resources/bin and open "dia" file with your prefer text editor.
4. It's time to add this line (export DISPLAY=:0) into the code:
5. Before line 27 and after line 40. (Remember the code to add is: export DISPLAY=:0)
6. Must looks like the attached image.
7. Save the changes and run Dia.
8. Everything nust be good with a functional Dia.

[Pawel Ciejka]

Well this script seems a little bit outdated, I don't see any reason to export DISPLAY in this script. There is also a second error preventing console usage for genereting images from diagrams. Arguments to script are not passed to dia binary. Proposed solution gets rid off both.
