How many ram do you have on your computer?
Try building without the release option, it might take less memory.

You can check the available memory with free -h

hmm, just 283MB,,, but can i run in 5GB free memory (on my desktop) ?

just 283MB...

This is too low I think, you'll get into trouble (and slow-ness) soon if you don't add more ram.

but can i run in 5GB free memory (on my desktop) ?

Is it a question? What do you mean?

I would say at least 2gb of available memory (please see http://www.linuxatemyram.com, you're reading free wrong) is required to compile most crystal programs. Maybe close a few applications of you have 5gb of total memory.

To expand on what @RX14 said, in particular, try closing any Chromium-/Electron-based applications (e.g. Chrome/Chromium, Atom, VS Code, Slack, Spotify, etc.).

"Is it a question? What do you mean?" i askin that question before start working in desktop :D, if you say yes, then i'll start, and RX14 just say yes :D

after closing atom, my free memori is 400MB > ( < 500MB ), and its work to run crystal compiler, thanks kirby

FWIW if you like Atom, you might like VS Code, which is similar but IIRC a bit more lightweight.

Also cough shameless plug http://howl.io cough

[codenoid]

i just change to sublime text

if you build without "--release" then it doesn't take as much RAM to compile, FWIW.

Closing, seems the issue was solved
