Arch Linux User Repository

multimc is no longer using stable releases, which obsoletes this package (see this commit)

please consider switching to prismlauncher for continued support. you can find a migration guide here

edit: multimc-git was previously recommended, but has not been updated for more than a year and does not build off develop currently, so it has been removed. multimc-bin may also not be viable for the same reasons as this package, so the only alternative i am comfortable recommending is prismlauncher.

Leaving this as a permanent disclaimer:

It is illegal to redistribute any binaries created with this script because of the upstream project's licensing.

Any chance to make the Microsoft login work in this package? It only works in the prebuilt one (multimc-bin) atm.

See related GitHub issue.

@gameslayer: You probably have jre-openjdk, jre8-openjdk and jdk8-openjdk installed but not jdk-openjdk. It builds fine with jdk-openjdk 16.0.2.u7-1

had to set my java version to java-8-openjdk to make it build successfully otherwise I ran into this issue

@ISSOtm: thanks, I never come across such problems because I always build in clean chroots. I ended up using symlinks instead, you might have to remove the leftover directories once (or just use makepkg -C).

The package does not support building on top of an already-built repo; this patch fixes it.

just in case. fails to build with java-15-openjdk. archlinux-java set java-11-openjdk and back to 15 after install

@katt: many thanks for the patch and sorry for the wait.

Needs this patch applied now that GCC 11 is in core: https://github.com/MultiMC/MultiMC5/pull/3747

This gets it to 80%, then it needs this applied as well: https://github.com/MultiMC/MultiMC5/commit/3a1abb555b844c79a80615727b11019403767ce7.patch
