Arch Linux User Repository

I don't know where people keep getting this from, but please stop flagging the package out of date with links to old release announcements from a year ago. 0.6.11, from 2020-03-29, is the latest release as of right now.

just a friendly reminder even though this installs packages of jdk < 12 it will still attempt to use the default one which may be set to 12 like in my case.

You need to use sudo archlinux-java status and sudo archlinux-java set java-11-openjdk to figure out what you have and set something lower than 12 as default before attempting to install.

About the Cmake-error:

If someone is confused about jdkX (whereas X = java environment you have), you should check with "sudo archlinux-java status" what kind of java environment you have. Mine was defaulted to java-8-openjdk/jre which unfortunately didn't work, so i installed only the jdk8-openjdk-package with "sudo pacman -S jdk8-openjdk" and the install worked for me after that. Im guessing the -jre is same problem for all java environments and this fix should work in the other environments too, but im not sure.

I did not remove the "jre"-jdk8 package: the package overrided it automatically.

Why can't you set the JAVA_HOME env variable in the build function, like is done in the multimc-git package (https://aur.archlinux.org/packages/multimc-git/). It seems to work fine like this, and could solve a lot of frustration.

@xiretza thanks, I set java to openjdk 8 and everything works nice now

@Wennadocta: first off, it builds fine in a clean chroot, which is the only setup that can be supported reasonably - AUR helpers in particular are completely out of scope, I suggest you at least use makepkg before reporting any package bugs in the future. Also, did you read the pinned comment? I think it might solve your problem.

Last version doesn't compile

/home/ayanami/.cache/yay/multimc5/src/MultiMC5-0.6.11/cmake
CMake Error at libraries/launcher/CMakeLists.txt:2 (project):

  Tell CMake where to find the compiler by setting either the environment

  the full path to the compiler, or to the compiler name if it is in the
  PATH.

@xirertza Yeah, that did the trick. Turned out I was using jdk 13, switched to version 8 and it worked like a charm.

@sybsfksks: "doesn't work" is about the least helpful error report possible. I just created a 1.10 instance, then installed forge 12.18.0.2000 from the "Version" menu of the instance, and it launches just fine using Java 8.

Edit: just saw you added a stack trace - the full log would probably show that the java version you're using is too new.

On the latest version, any version below 1.12.2 with forge doesn't work for some reason. Here's the full error: https://pastebin.com/nKCM7tjJ

@mcmacker4: please use MAKEFLAGS= in makepkg.conf for this, that way it applies to all packages you build and package maintainers don't have to implement it separately for every package.
