Yes, rust is an absolute Pig resource-wise. Not only does it carry a copy of llvm inside itself (it most probably has to), it also carries a nubmer of other packages inside. Plus, the build builds most parts at least twice if I've been able to observe correctly. When building on NetBSD/amd64 8.0, I noticed that the work/ directory after a "make" consumes in the order of 10G disk space, possibly more when cross-building (my current work/ is 13G, which is an unfinished cross-build because I hit build issues...). It is conceivable that the storage could be reduced somewhat (but probably not by much?) by tweaking src/bootstrap/boostrap.py to say -Cdebuginfo=0 instead of 2 for RUSTFLAGS. So that you have an idea what to expect: My amd64 build host has 8G real memory, and a 2G tmpfs /tmp, and ... it didn't run out of space anywhere :) On this particular host (i7 3rd-gen, 4 real cores, 8 w/HT, pkgsrc and system on SSD) the build of 1.29.2 completed in a little over 2 hours wall-clock time, csh's "time" report at the end of the build was 40468.007u 1958.277s 2:04:42.18 567.0% 0+0k 10302+100556io 129329pf+0w So, yes, the build makes fairly good use of the multiple cores; notice the 567.0%, which, if I've understood correctly, indicates approx. 5.7* parallelism on average. The last version I managed to build on one of my NetBSD/macppc 8.0 machines (a single-core 1.5GHz G4 Mac Mini, 1GB memory) was 1.29.2, the build took nearly 29 hours wallclock time. This one doesn't have a tmpfs, and has a single file system with ~40G free, so it also didn't run into any barriers on the /tmp front either. Regards, - HÃ¥vard
