I've set up a linux VM (ubuntu 15.10) in virtualbox on my windows PC to
build and test swift on linux, but I've been unable to successfully
build it to completion. I have all the repos including the corelibs
cloned locally, and have followed all the steps as far as I know for
installing dependencies. Every time I build, it fails somewhere during
linking, the last time failing when linking "CXX shared library
lib/libLTO.so".
I don't have the full error, but I'm curious if there's some RAM
requirement for building swift. My VM had 2GB, and I just bumped it up
to 4GB to try again. Has anyone else run into this, and is there a
recommended minimum needed to successfully build swift with? Could
something else be the cause here instead of RAM if 2GB is in fact enough?
Hi,
to build Swift from the sources I used a 16 GB bare metal machine and it
was not enough.
So I think, you need a lot of memory ( > 16 GB) to have fun while building
it.

I started with a Linux VM with 8G of physical RAM, and 4G of swap, and it wouldn’t compile using the instructions on Apple’s Github page (i.e., utils/build-script -t). I eventually managed to get it to build by bumping the VM’s RAM allocation up to 16G, and the amount of swap space to 14G. Even then, it took a very long time (I left it running overnight). It seems to be the linking phase that requires so much memory.

For those hitting this issue, you might try building without debug info to see if that helps (build-script -R).

I was able to build it on my 8GB macbook successfully, but there may be platform differences there that caused that.
It seems that 4GB isn't enough either, fails when linking clang-3.8. I'll have to figure something else out for linux for me. Thanks!

This appears to have helped me. I’m on to testing the build, it appears my linker woes are behind me. Thanks!
