问题
I hope you can help me. I have written a small project using CxxTest on my main dev machine. Everything works great on this machine, no problems. However, I tried setting up this project on my brand new laptop and just can\'t get it to work! I suspect something is messed up with my MinGW installation rather than CxxTest, but it\'s really hard to know - and the errors originate from CxxTest files. This is the folder structure of the project:
lib/
cxxtest-4.3/
src/
TestUtils.h
test.cpp
test/
MyTestSuite.h
libstdc++-6.dll
On the command line I run:
cd test
..\\lib\\cxxtest-4.3\\bin\\cxxtestgen --error-printer -o runner.cpp MyTestSuite.h
This generates runner.cpp. Now I run:
g++ -o runner.exe runner.cpp -I \"../lib/cxxtest-4.3\" -std=c++11
This usually works fine, outputting runner.exe and running my unit tests. On my laptop I just get thousands of errors. Here\'s a look at just the first few:

When I run g++ on a simple hello world file, it works fine. Does anyone know what\'s going on?
回答1:
I also recently updated MinGW and ran into very very similar problems. After some research I found this question on SO and tried replacing -std=c++11 with -std=gnu++11. This resolved the issue for me. Hope that helps!
