@gderber Here is a link for what they say is required for Linux:

@Unknown This is a problem with building the decaf emulator. I have a 3tb hd about 50% capacity installed. I have 16GB ram in the system.

The problem is a missing dependency. One that is not listed in the decaf documentation. I have already identified 2 of those. I haven't identified this one.

A Former User

I've identified the missing dependencies. Build gets a little further.

Current script is at the same link.

For some reason even with

export CC="/usr/bin/gcc-8"
export CXX="/usr/bin/g++-8"

Cmake seems determined to use
/usr/bin/g++ which is a symlink to /usr/bin/g++-7

When I point the symlink for g++ to g++-8 it gets to about 92% completion. Without that change, it gets to about 56%. The decaf docs do specify g++-8 is needed. I don't like the idea of checking a systems g++ symlink and changing if needed.

A Former User

A quick update. As long as g++ is a symlink to g++-8 and the SDL frontend is used instead of th QT5 frontend, I have a successful build.

Unknown

@gderber So decaf is now working?

A Former User

@Unknown I have a successful build. Haven't tried running it yet. It might be this weekend before I get to that.

I want to test the script installation, and use that for testing how well decaf runs.

Unknown

@gderber I understand.

Unknown

@gderber Any progress on decaf? Just curious.

A Former User

@Unknown Script I have installs the decaf-cli binary. Currently it won't run anything. I have more debugging to do.

Unknown

@gderber Do you mind if I ask you about the progress of decaf once a week? If not that's perfectly fine.

A Former User

@Unknown As it currently stands, the installer will install decaf.

Decaf isn't working for me, and the error message is not very helpful. I don't remember exactly what it said, but it was about as helpful as

decaf started
decaf exited

I've got a few other projects that I'm working on, unfortunately for now, this one is going to the bottom of the pile. I've made available what I have done so far, if you or anyone else would like to work on it and try to get decaf to work, go for it.

Unknown

@gderber Can you give me a copy of the code you have written so far? It would save me a lot of time! :)

A Former User

@Unknown https://raw.githubusercontent.com/gderber/RetroPie-Setup/feature/decaf/scriptmodules/emulators/decaf.sh

Here you go. I didn't realize I broke my link from earlier. It's fixed now.

Unknown

@gderber Thanks, so I just try to run this in emulationstation right?

A Former User

@Unknown No, add it to your RetroPie-Setup/scriptmodules/emulators folder then run retropie_setup.sh select packages, then experimental, then decaf.

This will install decaf

Unknown

@gderber At that point does it work with emulationstation? Or do I need to run a terminal command? I probably am going to ask a lot more questions because I've never added an emulator to retro pie before.

A Former User

@Unknown You'll need to use a terminal command. The same one used to setup RetroPie to begin with, sudo retropie_setup.sh

Unknown

@gderber After it is installed, should I try it with emulationstation?

Unknown

@gderber Or do I need to edit emulationstation config?

Unknown

@gderber I just relized that I don't have a computer powerful enough to test this. Good luck getting it to work!
