Please understand that I'm not trying to be obstinate, I'm trying to understand. Background: years ago I managed the cluster of i386 blades that we used in package building. 933MHz and 512MB IIRC. So I am familiar with constraint problems. On Wed, Oct 04, 2017 at 02:22:25PM -0700, Steve Kargl wrote: > Can't find info on whether jails can be avoided. I have not checked the code but IIRC, no.

For point of comparison, with those constraints, I do not understand how modern llvms can build at all. What happens if you use the manual approach on this same system? e.g. cd /usr/ports/devel/llvm40 mkdir -p /usr/ports/packages make && make package pkg install /usr/ports/packages/llvm<whatever>.txz Do you still run out of resources? In that case, there's not much that can be done. The compilers, the office suites, and certain math packages are huge beasts. However you try to build them won't matter. I would think having a copy of the llvm workfiles in a jail is going to be equivalent to having them in /tmp? I must be missing something. mcl
