undefined reference to `pthread_key_create' (linker error)

Question

I have downloaded gtest 1.7.0 sources from here:

https://code.google.com/p/googletest/downloads/list

and build the gtest .a files (lib files) on ubuntu 13.10

Answer 1

Use -pthread instead of -lpthread (for linking with pthread-library), while you using gtest in your executable.

OR

Move the -lpthread after libgtest.a (sequence matters).
