How to prepare a .dmg application from SDL2 build for MacOS

[geoffreyvanwyk]

The latest release does not contain a .dmg for MacOS. I ran make sdl2 myself on the v2.3.0 tag. How can I now turn that into an application that can be launched like other GUI apps?

I would start with something like this:
https://apple.stackexchange.com/questions/224394/how-to-make-a-mac-os-x-app-with-a-shell-script

Let me know how you get on and we (or maybe you :) ) can add it to the documentation.

I might also get a chance to do this in a couple of weeks, in which case I will share here.

You can run lem from wherever your executable is (usually in the directory where you compiled it:
./lem -i sdl2

That will change soon as LEM is changing to webview.

• Launch Automator.
• Click Application Type

• Select and double click on Run Shell Script

Clear out the shell script content, and replace it with the following:

source ~/.zshrc
cd ~/common-lisp/lem
./lem -i sdl2 &
exit 0

If you built your lem file somewhere different, then you'll have to provide that folder instead. And obviously if you rename your lem executable to something else, you'll need to reference that instead.

Save this in the file format 'Application' (this is the default) to your /Applications folder with the name "Lem".

This should now work.

This isn't a dmg file obviously, but I assumed you just wanted an application file.

There's probably an easier solution - but this will work.

There are also nightly builds now as well.
