Gtest: Undefined References

Question

I am trying to use GoogleTest to test a simple function, but as I run make in my build folder, the compiler throws Undefined Reference error messag

Answer 1

Put the libgtest.a after your object files

If you are doing things manually instead of with CMake, make sure to do:

g++ main.cpp googletest/build/lib/libgtest.a

instead of:

g++ googletest/build/lib/libgtest.a main.cpp

Here's a full working example I've tested with: https://askubuntu.com/questions/97626/how-to-install-googletest/1295185#1295185

This problem is not exclusive to GoogleTest: I can also reproduce it with a minimal library example like this one and Eli explainss the ordering rules which I don't have the patience to learn right now.
