Undefined reference to _unwind_resume when using Google test

I set up Google test for some test driven development on my desktop PC and all went well. Now I'm away from home, I have downloaded my code and set up google test in the same way on my laptop and all is not well. Google test compiles fine, but I get "undefined reference to _unwind_resume" messages when compiling my tests.

Both my Desktop and laptop are running Windows 7 with the latest MinGW and I followed the same steps set it up. I am using Code::Blocks to compile the tests.

This is what I have used to compile the Google test and mock libraries:

g++ -IC:\Codes\programs\gmock-1.6.0\gtest/include -IC:\Codes\programs\gmock-1.6.0\gtest -IC:\Codes\programs\gmock-1.6.0/include -IC:\Codes\programs\gmock-1.6.0 -c C:\Codes\programs\gmock-1.6.0\gtest/src/gtest-all.cc

g++ -IC:\Codes\programs\gmock-1.6.0\gtest/include -IC:\Codes\programs\gmock-1.6.0\gtest -IC:\Codes\programs\gmock-1.6.0/include -IC:\Codes\programs\gmock-1.6.0 -c C:\Codes\programs\gmock-1.6.0/src/gmock-all.cc

ar -rv libgmock.a gtest-all.o gmock-all.o

This goes well and provides a libgmock.a file. That is then linked in the compiler settings in Code::Blocks and the correct include directories are specified too.

Building the tests in Code::Blocks gives these errors:

Compiler flags in Code::Blocks include -std=c++11 and -std=gnu++11

I can't work out what I've done differently to before and I'm a bit stuck.
