error: could not compile jiff (lib)

[jeremiah]

I tried this code:

cargo install --locked --bin jj jj-cli

I expected to see a successful build of the above packages, e.g. jj and jj-cli

Instead, this happened: error: could not compile jiff (lib)

Can't repro this 🤔

   Compiling jj-lib v0.28.2
    Finished `release` profile [optimized] target(s) in 1m 16s
  Installing /home/gh-jieyouxu/.cargo/bin/jj
   Installed package `jj-cli v0.28.2` (executable `jj`)

Does it still SIGILL SIGKILL if you try again?

Thanks @jieyouxu

[saethlin]

This is a SIGKILL which often but but always indicates OOM.

[jeremiah]

This is a SIGKILL which often but but always indicates OOM.

I'm in a container so I will see if I can add memory.

[saethlin]

You could also try building with -j1 which will be slower but may lower peak memory.

[jeremiah]

This time I ran out of memory on /tmp;

I've cleaned out /tmp a fair amount, but if that fails, should I build it somewhere else on disk with a command line flag?

[jeremiah]

This time I didn't run out of disk and free -h says 1.1G of available memory.

[saethlin]

It's quite possible you need more than 1.1 GB of memory to do a release build of jj-lib. Trying to run cargo install in a resource-constrained environment is just not going to go well. That's one of the reasons Jujutsu suggests you download a pre-built binary.

You can keep commenting here; but I don't see any reason that you'll get answers other than "give the compiler more resources".

[jeremiah]

Okay, that makes sense.
