[building libraries]: ERROR: Don't know how to translate x86_64-pc-linux-gnu for rustc

[Seleucids]

The build failure occured when running /libraries/build-source-libs.sh  It is at the checking stage.

I am using the latest code from gitea main branch as of 6th September 13:40 UTC

```

ERROR: SpiderMonkey build failed

I found some similar discussions about spidermonkey packages on the Gentoo forum
https://bugs.gentoo.org/915651

hopefully it can be of help

I had a similar problem, it looks like building spidermonkey requires huge amount of RAM, and if you don't have enough of it some build process crash.

If you are building with -jX (with X which works fine for 0ad and the other libraries), you may want to decrease X when running build-source-libs.sh , so there are less simultaneously build processes and maximum RAM usage decrease.

I have 32 GB of RAM

I used -j28 (usual value for 0ad in the past and building other AUR packages)

 

now i decreased to -j1. the same error occurs. 

 

I suspect this is more of a dependency version issue than a RAM issue

2GB per job is usually a good value, not enough for some packages, Webkit being notorious for needing about 4GB per job. Anyway dmesg will tell you if oom happened.
