py36-tensorflow @2.0.0: does not build

[brolcz]

When I attempt to upgrade py36-tensorflow, it does not build.

Sorry, I forgot to mention. My Mac OS is Mojave 10.14.6.

You need to post a complete log file from a clean build attempt....

[brolcz]

thank you, I have added it.

Log from port install for py37-tensorflow on macOS 10.15

[andrey-popov (Andrey Popov)]

I experience what seems to be a similar problem (segmentation fault during build) for py37-tensorflow @2.0.0 with macOS 10.15 and Xcode 11.1. I attached the full log (catalina.log). Note that this seems to be different from #59282 (where errors seem to be related to downloading of files).

[cjones051073 (Chris Jones)]

I have a suspicion that this might be another instance of the Xcode 11 + Darwin 19 '-fstack-check' issue we have been seeing in a few places. Testing applying the work around now. Seems to be working (build still going but has past where it previously failed). It will take a while, tensorflow is a mammoth build, but I will push something when I am sure it completes....

[cjones051073 (Chris Jones)]

sadly, this did not work.... for now, unless someone comes up with a good idea I'm going to consider this as something upstream needs to address themselves.

[cjones051073 (Chris Jones)]

Upstream already have an issue for this.

[ryandesign (Ryan Carsten Schmidt)]

Upstream has closed the issue, saying Xcode 11.4 and later fix the problem. So what do we need to do about that in MacPorts? We may have Xcode 11.4.1 on our build machine already but that's no guarantee that users have upgraded. Do we need to add an Xcode version check to the port (perhaps the xcodeversion portgroup)?

Your commit message says:

py-tensorflow: use xcode_workaround PG to require Xcode 11.4+ on macOS 10.15

What about on 10.14? This ticket was originally reported by a user using Xcode 11.0 on macOS 10.14.

[cjones051073 (Chris Jones)]

I guess in principle someone if they wanted to could update the PG to work on 10.14..

Support for Python 3.6 was dropped for py-tensorflow some time ago, so this ticket is no longer relevant. Closing.
