无法在 eclipse 中编译 googletest

Question

I am trying to compile googletest (git clone https://github.com/google/googletest.git -b release-1.11.0) but keep getting 1000+ linker errors.

I am running windows 10, eclipse CDT (latest), mingw (latest) gcc. I created an eclipse c++ project (executable, empty project).

added include paths to:

• googletest
• googletest/includes
• googlemock
• googlemock/includes

added source location to:

• googletest/src
• googlemock/src

All is compiled without problems, but linking fails with 1000+ errors. Eg.

I am reading googletests readme.md to figure out what I am doing wrong but getting nowhere. Some help would be greatly appreciated

Ah, there is a file googletest/src/gtest-all.cc

which includes all source files. so all source files are compiled twice, deleting this file solves my problem
