Google tests runtime undefined reference

Question

I'm able to run the Google tests setup in the official Jetbrains Clion guide using TEST_F macros but I'm not able to setup the same environment for my project. The following is the test class I'm trying to run, everytime I refer to the ed1 instance I get a bunch of undefined reference errors.

#include "gtest/gtest.h"
#include "../NetworkServer.h"

class SharedEditorTest : public ::testing::Test {

protected:

    virtual void SetUp() {

        ed1 = new SharedEditor(server);

        /*ed1->getSymbols().push_back(Symbol(char('a'), std::string{"0_1"}, std::vector<int>{1}));
        ed1->getSymbols().push_back(Symbol(char('n'), std::string{"0_2"}, std::vector<int>{2}));
        ed1->getSymbols().push_back(Symbol(char('t'), std::string{"0_3"}, std::vector<int>{3}));
        ed1->getSymbols().push_back(Symbol(char('o'), std::string{"0_4"}, std::vector<int>{4}));
        ed1->getSymbols().push_back(Symbol(char('n'), std::string{"0_5"}, std::vector<int>{5}));
        ed1->getSymbols().push_back(Symbol(char('i'), std::string{"0_6"}, std::vector<int>{6}));
        ed1->getSymbols().push_back(Symbol(char('o'), std::string{"0_7"}, std::vector<int>{7}));
        std::cout << "ed1: " << ed1->to_string() << std::endl;*/
    }

    virtual void TearDown() {

    }

    NetworkServer server;
    SharedEditor* ed1{};
};


TEST_F(SharedEditorTest, TestName) {
    std::cout << ed1->getCounter() << std::endl;
}

int main(int argc, char **argv) {
    ::testing::InitGoogleTest(&argc, argv);
    return RUN_ALL_TESTS();
}

Output

Shouw us your build system (`CMakeLists.txt`, `MakeFile` or whatever you are using). Issue is likely there. — Yksisarvinen, Mar 13 '20 at 12:21
Can you show which references are undefined? No idea what is missing as you did not provide the info. Is it missing gtest, stl, clib or ... ? — Klaus, Mar 13 '20 at 12:34
Where did you specify to link with the object containing SharedEditor code ? — Gojita, Mar 13 '20 at 12:38
@Gojita do you mean linking Google_tests with my source files? — TonyRomero, Mar 13 '20 at 12:40
I could just supose that, somewhere, there's the code of SharedEditor::getCounter. Perhaps have you done a library with it ... don't know. But, you should link your Google_Tests_run with the object countaining the getCounter code. SharedEditor.cpp is only compiled to create an executable, but you did not create a library. Add it also in add_executable of your Google_Tests_run or create a library — Gojita, Mar 13 '20 at 12:42
