All unit tests fail?

[QuantumDonDoerner]

Using up-level cmake:
%cmake3 --version
cmake3 version 3.6.3

Using up-level compiler (6.3.0, on the list)
%c++ --version
c++ (GCC) 6.3.0

Tests built with a couple of innocuous warnings like this:
.../json/test/src/unit-serialization.cpp:71:18: warning: ‘std::ostream& nlohmann::operator>>(const
nlohmann::basic_json<>&, std::ostream&)’ is deprecated [-Wdeprecated-declarations]

But all tests fail: "0% tests passed, 70 tests failed out of 70"

Any idea what may be happening?

We compile and execute the test suite without problems using GCC 6.3.0 on Ubuntu, see https://travis-ci.org/nlohmann/json/jobs/287422140.

Did you run the tests like this?

$ mkdir build
$ cd build
$ cmake ..
$ cmake --build .
$ ctest

[QuantumDonDoerner]

Yes, I ran them exactly as directed on the page https://github.com/nlohmann/json#projects-using-json-for-modern-c, except that I am working on CentOS 7 (1611) not Ubuntu. I just looked: %ctest --version ctest version 2.8.12.2 By chance is there a ctest version requirement that I may not be meeting?

That's it. Do not forget to set the necessary switches to enable C++11 (e.g., -std=c++11 for GCC and Clang). Thanks,

I am using ctest version 3.9.4. To be sure, can you provide some log files from the failing tests? It's hard to tell right now.

[QuantumDonDoerner]

Found it, my mistake, please close the issue. FYI, the problem was that when I updated my compiler, I didn't point at the right libraries. Thanks,
