Build Error [-Werror-deprecated-copy]

[acxz]

I am getting a build error on the latest release: 1.3.0

Steps to reproduce:
mkdir build && cd build
cmake ..
make

Output:

OS: ArchLinux
GCC: 9.2.0

Can a new release be made with a working build? As it is right now, the ArchLinux package is breaking. Thank you. The fix also seems to be pretty quick. Either we pass the deprecated errors as warnings or we use the updated api.

Closing this issue as I am not using this repo anymore and it seems as this repo is stale.

[scheibel]

You should leave issues open, although they don't affect you anymore. In this case, the issue is with our repository and only partially tied to your personal usage. Further, I want to affirm this repository is not stale. It just happens that our code does what it should without much interference.

Quick investigation: the issue is not within our code. A simple workaround that you as well as ArchLinux maintainers (more generally: users of GCC 9.x) could use is to build the library with tests disabled (switching the CMake option OPTION_BUILD_TESTS to Off). What we experience here is a change in warning behavior after a compiler upgrade.
The issue is resolved by updating the googletest dependency used for testing.
