Comments

it appears that cc1plus.exe runs out of memory (2gb ram?) -- there are workarounds, e.g. https://sysprogs.com/w/forums/topic/cc1plus-exe-out-of-memory-allocating-65536-bytes/

found this other thread...http://itensor.org/support/1260/installation....didn't seem resolved then (I also tried O2->O3 replacement), also didn't work from ubuntu (under windows) with a different looking error, still on the same file

Hi Vadim, thanks for bringing this up. It's been a thorn in our side in wanting to support Windows, but cygwin's compiler not being very good. So we could keep coming up with workarounds, but really it's a bug that's with cygwin and not with ITensor per se.

I was going to suggest you try Ubuntu on Windows instead (https://www.microsoft.com/en-us/p/ubuntu/9nblggh4msv6?activetab=pivot:overviewtab). But did you say above that you tried that already and it didn't work? If so, what didn't work? Was it the same issue or a different issue? Thanks -

Miles

yup. ubuntu make chokes on the same file as Cygwin albeit with somewhat different error (see below). I haven't had the time to educate myself re: "-mbig-obj". Also, I am not sure if I ran ubuntu on a fresh copy of itensor...maybe that is important.

Hi Vadim, glad you are trying that instead.

Based on the error message, it actually looks like the Ubuntu one is not (yet) choking on the file, but rather saying it doesn't recognize the "-mbig-obj" flag. So could you please try removing that flag and compiling again?
