As a stopgap, you might consider adding a small swapfile and setting swapiness to a low value. Nearly every ARM gadget I had was suffering OOM kills on two C++ libraries that made heavy use of templates. The swapfile and swappiness avoided most of the build problems I was encountering. The SD Cards are dirt cheap, so I don't care if they wear them out 15% faster than normal. Its an easier problem to solve than daily broken compiles. Jeff
