First of all, I am new to MacOS, and what I want is to be able to see the output of llc -view-dag-combine1-dags sum.ll. On Mac, will generate dot in /tmp directory, and try open App to show the dot file. I have tried, but it doesn't work (the program crash).
I would like try something else, like for example. I install it by brew install xdot, but don't know how to let the MacOS use the xdot I just installed to open the dot file. Or any other better tool to view the dot file? I would like to keep thing as simple as possible.
You can also build the Graphviz GUI app using homebrew if you have Xcode installed: brew install graphviz -with-app If you already installed the graphviz brew, you will want to do this: brew reinstall graphviz -with-app At the time of writing, this doesn't appear to install a symlink to the app into /Applications like cask does, so if you want that you'll need to do it manually (or copy the application out). To find the location of the app bundle, have a look at the build log, you should see a line like this:./configure -prefix=/usr/local/Cellar/graphviz/2.40.1 If you don't have the build log anymore, you can determine this path by running brew list graphviz or brew info graphviz. Open up the folder (replace this with the actual path you determined in the previous step): open /usr/local/Cellar/graphviz/2.40.1 Inside here you should see Graphviz.app.
You can move/copy it to /Applications or create an alias by dragging it to /Applications and holding the ⌘ and option keys.
I would like to distribute an App through the Mac App Store and will hence need to use Sandboxing. Problem is that I don't know how to configure Graphviz in a Sandbox-compatible way. Graphviz is based on plugins and requires that I:. Use an environment variable (GVBINDIR) to set the plugin directory.

The variable has to point to a directory within the Sandbox. Have a file in GVBINDIR directory location that is called config6 which is used to register plugin libraries. I could copy the file from the Name.app/Contents/Resources there.
Have 2 plugin dylibs in that same GVBINDIR. If I understand it correctly, then the Mach-O Linker settings have to be correctly set for the plugin library prior to deployment and in alignment with the directory. The following screenshot is based on a run with Xcode instruments, monitoring file access, but filtering to dotlayout plugin. As you can see it is found when the app starts (I have it as dependency, you see the FD return '3' - I don't really know what that means). But later, when graphviz triggers the access to the plugin, dyld cannot find it.

What am I doing wrong? Many thanks in advance!
