I've tried all the suggested methods (upping overcommit_ratio, putting 0,0,0,0... into minfree), cc1plus is still being killed when compiling on device.

why, just why do you compile on-device?

Because I can (at least in theory, not atm), with tohkbd hoping this will work just like n900 so will be able to put all the commute time to use

Thanks, but cc1plus still gets killed (it does act weridly with those values, as it didn't kill the browser running in the background, with the previous settings I tried everything running in the background was killed too)

@Nieldk this is proper answer, weird behaviour of not killing browser was the oom not kicking in, just watched htop to see how gcc eats through all swap and remaining ram, will need to increase swap (pls convert to answer)

If you really intendo to compile on-device, try this:

thanks but that does nothing, gcc fails at allocating memory, so same end result unless you didn't mean ulimit but what the guy had in mind asking that question and lowering memory usage of already compiled app, but that is irrelevant here

Yes, I meant ulimit
