Multimc5: Arch Linux | MultiMC won't install through yay.

[RavenChan1023]

System Information

MultiMC version: 0.6.5

Operating System: Arch Linux (x64)

Summary of the issue or suggestion: Yay doesn't install MultiMC and instead aborts and tells me to check the log.

What should happen: It should install and be ready to run right from the get-go.

Steps to reproduce the issue (Add more if needed):

1. Open Konsole (or terminal of your choice)

2. Use the command: yay -S multimc5

3. When it asks if you want to remove make dependencies afterwards, hit y then hit enter

4. Enter password

5. Everything else will download and install just fine but MultiMC itself will not install.

Suspected cause:

My only guess is that it may be a possible issue with the aur package, as everything else I install with yay tend to work just fine. I'll poke at other angles and see if it's not a dependency problem, but I figured I'd make this post ahead of time in case I don't end up resolving it myself.

Logs/Screenshots:

I do not own the multimc5 package... Contact its maintainer.

AUR package maintainer here, I can't reproduce it in a clean chroot. Since it fails inside a CMake check, it really is unlikely to be MultiMC's fault - much more likely a system misconfiguration.

@RavenChan1023 are you up to date (pacman -Syu)?

Edit: also, use makepkg, yay is just in the way when debugging things like this.

[RavenChan1023]

@Xiretza I wasn't up to date, I'll perform a full upgrade then clone the git, provided I don't come across any issues after the upgrade.

Same issue when trying to build it manually.

It gives me way more information now though, so I'll try what it suggests.

So were you able to resolve the issue?

[Janrupf]

Install jdk8-openjdk

[143mailliw]

I have this error as well.
I have multiple versions of java, if that helps.
jdk8-openjdk is installed.

[Recidiviste]

I have the same issue, and installing other java versions doesn't works. The answer is to change java version thanks archlinux-java
Just type sudo archlinux-java set java-11-openjdk and then yay -S multimc5, and it'll works perfectly !

Edit : For other distros, you have to find a way to change the java version the system will use (archlinux-java do it for us). But if the issue is for Archlinux, it should be resolved !

[Arzte]

Can confirm, if you're running a newer version of java, using archlinux-java to set a older version fixes the compile error. I had openJDK 12 set as my default, so changing it to 11 fixed it for me. (which I also had installed)

[AtomToast]

Same issue still persists but the provided fix via archlinux-java does fix it.
It does not seem to work with either 10 or 12

[strimmlarn]

sudo archlinux-java set java-14-openjdk

Solved it for me.

So I guess openjdk version don't matter that much just that you point to the package or whatever with the archlinux-java command

[Janrupf]

Java 14 sounds like a bad idea. It is possible that you won't be able to start Minecraft with older Java versions using MultiMC now
