Why is my yaml build failing test? yaml-cpp-0.6.0: handler_test.cpp:(.text+0x9f2): undefined reference to `testing::internal::GetWithoutMatchers()'

Question

When I install the astronomy software purify. It needs a latest version of yaml like yaml-cpp-0.6.0 I didn't encounter any errors, standard output is like

it looks alright. But when I input "make" in the linux shell it throws out a error in the end of the building process, seems to fail some tests. Do i need to install a separate test framework?

I'm so clumsy that I cannot get any useful information from the error code. I need help QAQ

Answer 1

To prove to yourself where the problem stems from, on line 24 of CMakeLists.txt, temporarily change the "Enable testing" option to off and retry:

option(YAML_CPP_BUILD_TESTS "Enable testing" ON)

if(YAML_CPP_BUILD_TESTS) enable_testing() add_subdirectory(test) endif()

Notice that yaml-cpp uses "Google Test" a

merger of the formerly separate GoogleTest and GoogleMock projects

so either there is another version of Google Test in your path or the yaml-cpp project is not automatically building the Google Test suite in its tree. So ascertain whether https://github.com/jbeder/yaml-cpp/tree/master/test and subcomponents is being built.
