Looks like some recent changes should address this:  
[https://github.com/google/googletest/pull/1218](https://github.com/google/googletest/pull/1218)

GTest does not do frequent releases, so we will likely have to go with the master branch and hope it’s bug free for our purpose.

Using master version of GTest is better than having build failures 😃

Can you create a patch for it @blowekamp?

If someone is going to update gtest, maybe you could take a look at this too:

[https://github.com/google/googletest/issues/1154](https://github.com/google/googletest/issues/1154)

(My impression is that the gtest project is moribund.)

I hope to get around to it tomorrow. I see a VS 2017 build on the dashboard is this issue expect to be shown there?

This started happening maybe a week or two ago (I keep my VS2017 up to date). I think that all dashboard machines were set up before then, and don’t include the update which broke GTest.

I ran into a merge conflict running “Modules/ThirdParty/GoogleTest/UpdateFromUpstream.sh”. Reading through the scripts to find out how best to resolve… pointers could expedite the processes.

For the third party scripts, is appear I just needed to to resolve the merge and the do a “git commit”.

@dzenanz I have just updated my VS 2017, and did a fresh build of ITK. I am still getting the same warning, which is treated as an error. I was able to define "\_SILENCE\_TR1\_NAMESPACE\_DEPRECATION\_WARNING " and ITK compilation was successful.

Can you please verify that the current ITK master is working for you and VS2017?

I just pulled master and started a build in VS2017. I will let you know about the result.

It still compiles without errors. I only got 4 warnings of the kind `LNK4221	This object file does not define any previously undefined public symbols, so it will not be used by any link operation that consumes this library` in project _hdf5-static_.

Ah, I was on the v4.13rc2 tag, compile on master is OK for me too.
