Youcompleteme: Compilation runs out of memory
0
I have a 1GB VM (A t2.micro AWS EC2 instance) that I'm trying to set YCM up on, and I can't do it because it fails.

Anyone know of tricks to limit the compiler to prevent it from trying to swap? I'll add a swap partition and try again, but in the meantime... maybe there's something I could do.

This is covered in the FAQ; you don't need a swapfile.

@Valloric - Even with YCM_CORES=1 ./install.py --clang-completer, I ended up with same error.

Any hint/help?

@jitendra-1217 Have you tried the swap file suggested earlier?

@vheon - No I though official wiki suggested this single job at a time solution should work. I will try that..

Ran into the same problem just now. Tried YCM_CORES=1 without success. However adding a swap file suggested did work.
