SUMO installs, but does not run on M2 Mac running Sonoma

[robstallman]

Summary

SUMO install on MacOS Sonoma appears to be successful, but

robstallman@Robs-Laptop ~ % sumo
zsh: command not found: sumo
robstallman@Robs-Laptop ~ % sumo-gui
zsh: command not found: sumo-gui

System Information

• SUMO-version: 1.20.0
• OS: Sonoma 14.2
• Chip: Apple M2

Installation Method

• Installed for macOS using Homebrew as described in SUMO Documentation
• Homebrew version: Homebrew 4.4.17
• Prepare for install by installing XQuartz
  XQuartz version: 2.8.5

Issue Description

1. SUMO was installed by running brew tap dlr-ts/sumo / brew install sumo, which appears to install without issue:

==> Summary

==> Caveats
==> sumo
In order to let X11 start automatically whenever a GUI-based SUMO application
(e.g., "sumo-gui") is called, you need to log out and in again.
Alternatively, start X11 manually by pressing cmd-space and entering "XQuartz".

Don't forget to set your SUMO_HOME environment variable:
  export SUMO_HOME="/usr/local/Cellar/sumo/1.20.0/share/sumo"

Please report any problems with this formula directly to the eclipse-sumo/sumo issue tracker:
https://github.com/eclipse-sumo/sumo/issues

2. 🚩The SUMO_HOME path specified during the installation process does not exist:

robstallman@Robs-Laptop ~ % ls -alt /usr/local/Cellar/sumo/1.20.0/share/sumo
ls: /usr/local/Cellar/sumo/1.20.0/share/sumo: No such file or directory

Instead, the correct path seems to be /usr/local/Cellar/sumo/1.20.0.reinstall/share/sumo

3. The corrected $SUMO_HOME path is added to .zshrc, and the user is logged out/logged back in
   Note: This process was also attempted without modifying the $SUMO_HOME path as specified in the installation, but the issue is the same either way.

4. macOS application bundles for sumo-gui are installed, apparently successfully

5. Neither sumo, sumo-gui, or netedit opens on the command line:

robstallman@Robs-Laptop ~ % sumo
zsh: command not found: sumo
robstallman@Robs-Laptop ~ % sumo-gui
zsh: command not found: sumo-gui
robstallman@Robs-Laptop ~ % netedit
zsh: command not found: netedit

6. Neither sumo-gui or netedit opens from the Applications folder (even after permitting them)
   Note: A small gear icon appears in the menu bar when attempting to open the application, but this disappears within a second or two.

Yes, we know that the current version of installing sumo on macOS is flawed and working on a better solution.

Adapting the SUMO_HOME variable to the correct directory is a great first step. Now you need to SUMO_HOME/bin to the PATH.

To set this up in zsh, you can add the following lines to your ~/.zshrc file:

export SUMO_HOME="/usr/local/Cellar/sumo/1.20.0.reinstall/share/sumo"
export PATH=$SUMO_HOME/bin:$PATH

After editing the file, run source ~/.zshrc to apply the changes immediately."

Hi @RobertHilbrich, thanks for your reply.

After adding SUMO_HOME/bin to the PATH, the sumo command is recognized.

However, the program still does not run because the following error is thrown:

robstallman@Robs-Laptop ~ % sumo

zsh: abort      sumo

Inspecting the xerces-c installation, it appears that the SUMO installation has installed version 3.3, when it appears to require version 3.2 based on the error message above. Below are the contents of /usr/local/opt/xerces-c/lib:

robstallman@Robs-Laptop ~ % ls /usr/local/opt/xerces-c/lib/
cmake			libxerces-c-3.3.dylib	libxerces-c.a		libxerces-c.dylib	pkgconfig

Do you have any recommendations on resolving the error at this point?

Thanks again
