I am not able to build 1.0.6. I get out of memory errors and top shows I am actually out of memory. If I switch back to 1.0.5 everything builds fine and does not even get low on mem. Watching the build in top seems to show 1.0.6 creating many many more threads than 1.0.5...
are you building with
zcutil/build.sh -j<some number> which does a parallel make, or just
If the latter, you can always add swap, which I know is Not A Good Thing, but will get you there
Are you still having memory issues? What about when building on a fresh reboot?
I've filed a ticket about this just in case something has changed in the build script which causes more memory usage: https://github.com/zcash/zcash/issues/2154
Yes, I am still having this issue. I am building in a virtual ubuntu machine (vbox) with 7GB of memory allocated (6GB free after boot). I've restarted many times adjusting my memory allocated to the vm. I've built (I think) all the previous version of zcash without issue with total system memory of just 5GB. I am just using 1 CPU in the vm. I'll try 1.0.7 as soon as its out and maybe things will just work again.
1.0.7 is tagged in the repo, so you can build from source now
Just tried building tag v1.0.7 and I have the same high memory usage issue as with v1.0.6. It seems to just keep creating new cpp threads until memory fills up... The previous versions don't seem to behave like this? Can someone else just check their memory usage when you build? My build exceeds 4GB probably within 3-4 mins of the build.
what exact command line are you typing when you compile it?
See the below command line, I have tried with and without a make clean. I just started and terminated the build below before the memory fail error.

Try it with just
Hey, wow that was it. Weird I wouldn't have expected that behavior to change. Does the -j flag still work if you have more than one processor?
