Parallel Compilation Error

[ryanmrichard]

When I try to build TA in parallel I sometimes get the error:

fatal: destination path 'umpire-src' already exists and is not an empty directory.
[build] fatal: destination path 'umpire-src' already exists and is not an empty directory.
[build] CMake Error at umpire-ep-artifacts/Umpire-gitclone.cmake:31 (message):

it's nothing show stopping, as running build again fixes the problem, but thought I'd let you know.

I presume this is not standalone build of TA? Which revision of TA is this? did you use make? ninja?

Umpire is built using pure ExternalProject_add. So I don't think this is an issue with EP. If you are using recent TA then perhaps 51061e9 is the culprit?

[ryanmrichard]

This is the build of TA done by LibChemist, which looks like it's pinned to a somewhat old version 1b7e2e3. Let me try master and see if I still have the problem.

Looks like the error persists with master too.

[evaleev]

Could you please supply the full cmake args + invocation log?

I have been running into this too. For some reason, Umpire is trying to be built twice when the parallel builds happen. I think it may happen due to the separate Umpire-build and Umpire targets. At least, if I change the External-tiledarray dependency from Umpire-build to Umpire, I no longer get this error. I don't think that change affects any of the rest of the build because the Umpire target has a dummy install step.

Yea, this happens in MPQC too @evaleev - TA by itself is not an issue but how it interacts with being a subproject (this seems to be consistent with @awild82's observation)

@ryanmrichard you should check if this fixes the problem you were encountering, but the referenced PR fixes this problem for all instances I've encountered
