Azerothcore-wotlk: Build failing: reference to 'auto_ptr' is ambiguous

[Zebouski]

This occurs after the AUR package ACE is installed, and during the azerothcore package build:

I cannot confirm on Windows

[Zebouski]

I replicated again on a 2nd arch linux machine, same errors as above. https://www.azerothcore.org/wiki/arch-linux these instructions to be clear.

$ clang --version clang version 10.0.1 Target: x86_64-pc-linux-gnu Thread model: posix InstalledDir: /usr/bin

But I am unsure if it's a problem that could be addressed in https://aur.archlinux.org/packages/azerothcore/ or in this repo, or if its me doing something wrong

@Zebouski please add the required details to the issue report... e.g. AC commit hash, operating system, etc...

[FrancescoBorzi]

About the issue, I had the same on macOS and fixed together with @meerd

Not sure why you still have it. Are you using latest AC version?

[Zebouski]

Thanks, to clarify this is Arch Linux w/ clang version 10.0.1

using the https://aur.archlinux.org/packages/azerothcore/ AUR pkgbuild as per https://www.azerothcore.org/wiki/arch-linux

And yep it seems to be using the latest master commit 6ac68128d as expected:

[zeb@zebArchDesktop ~/.cache/yay/azerothcore/src/azerothcore-wotlk]$ git status
On branch master
Your branch is up to date with 'origin/master'.

nothing to commit, working tree clean

[zeb@zebArchDesktop ~/.cache/yay/azerothcore/src/azerothcore-wotlk]$ 

[FrancescoBorzi]

@Zebouski can you please try to compile a clean build and passing -DACE_LACKS_AUTO_PTR=1 to your cmake command?

[Zebouski]

A new clean build failed again with that cmake flag

But:

I just noticed that the AUR pkgbuild for ace was version 6.5.10, and that 6.5.11 was released just last week. I updated that ACE build to 6.5.11 and now azerothcore completes building as expected.

Sorry! It was a downstream issue. Thanks for your time

We should add a FAQ or Troubleshooting section in the wiki with these error and solution

[FrancescoBorzi]

@Zebouski awesome! Thanks for letting us know
