Errors When Compiling on Ubuntu 22.04

I am getting these errors while compiling, on Ubuntu 22.04:

Hello, just don't use the gtest? there is one available with apt, or just apt-get source lucene++ and build from there. There are few patches and configuration switches.

@LocutusOfBorg It is not my job to fix other people's build systems. If things don't compile correctly using the provided build files, then the programming team needs to fix that, not the users who don't want to waste time fixing other people's mistakes.

The programming team should also not be so slow to read and respond to these issues. I've already found a solution and moved on.

I guess "the programming team" in this case is me?

I certainly don't want to waste your time, but at the same time I don't have access to Ubuntu or the time to deep dive into this particular problem, apologies.

[LocutusOfBorg]

@krixano using bundled libraries is considered bad pratice in Debian and Ubuntu, this is why I suggested you to just use system provided googletest.
Or just build with -DENABLE_TEST=OFF

[LocutusOfBorg]

Also, works for me in the very same Ubuntu version, as well as Debian, so unless you provide build flags, and steps to reproduce, I guess there is not much we can do.

Reading the error message, the obvious solution is setting the dummy variable to 0, or any other value. Haven't you tried that?

Well, OTOH updating googletest to latest version will indeed fix this and other problems
google/googletest@4679637

V1.13.0 has the fix
