Leaving this here in case anyone is like me,
using an old macOS and don’t really care for updating to a new OS.
I have Mojave. I’m happy with it. I watched as people agonized over Catalina. I was happy until this error popped up when I tried to update erlang via asdf:
https://github.com/asdf-vm/asdf-erlang/issues/101
And that was the start of a very agonizing weekend.
Every single recommended method wouldn’t work.
The main reason is that XCode or Big Sur update changed location of glu.h, which is like an OpenGL library - that wxWidgets needs.
What does erlang have to do with wxWidgets?
Good question! It is because to render the Observer and the debugging GUI:
Well, I’m not an Erlang guru (yet) and I think Phoenix LiveDashboard has enough output that I don’t need the Observer.
I’ve never actually opened it up to do any debugging.
Sorry babbling on and on. Here’s what I did to DISABLE wx, thus disabling Observer in erlang, when using asdf to install:
Install XCode for your MacOS. Mine was Xcode 11.3.1 (https://developer.apple.com/download/all/?q=11.3 has all the older XCode). Yeah! It’s freagging 7 GIGS!!!
- No you can’t just install Command Line Tools for Xcode. I tried. No bueno. :(
Follow what this post does: https://github.com/kerl/kerl/issues/386#issue-1050365520
- Specifically:
export KERL_CONFIGURE_OPTIONS="–with-ssl=
brew --prefix [email protected]
--without-wx
--without-javac"And then install asdf:
- asdf install erlang 24.1.5
I almost cried. It got installed!
Oh my gosh. I already bought a new SSD and was getting ready to upgrade to Big Sur.
Why a new SSD? Stupid Big Sur won’t install, complaining I have disk issues. Sensitive little bastard. I’d remove Observer anyday. Small price to pay to not having to do a full backup of my Mac into new SSD, install Big Sur into new SSD, and then swap it out in my laptop by unscrewing + taking out the old one …. ew
