  i'm unsuccessfully trying to compile nim 1.6.2 on a 2gb arm sbc,

  seems link the minimum ram is 4gb

  You can either add swap or get the pre-built nightlies from https://github.com/nim-lang/nightlies/releases/tag/2021-12-14-version-1-6-48c62ca48bc1f0a0ff4bc891e720297b3e8e5c15 (these ones are from the version-1.6 branch, so while they don't correspond to a stable 1.6.x release they're a part of 1.6).

  thanx dude, both 1gb 32 bit & 2gb 64 bit linux on arm work fine on 1.6.1

  I was able to get Nim to compile on the RPI nano 2, with distcc and lots of swapping to disk

  cross compiling the source in a desktop box is probably the most feasible option

  Nim runs N backend C compiler processes at same time when nim c/cpp foo.nim command is executed on the machine with N CPUs. (See execCmdsInParallel or execCmdsInParallel proc in compiler/extccomp.nim)

  So adding --parallelBuild:1 option to Nim might reduce memory usage because Nim doesn't run multiple backend C compiler processes at same time.

  If it can help, Nim is packaged in Debian and built for approx 10 architectures including ARM. Also, the package supports crosscompiling.
