Hi,

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 new laptop (dell xps13) 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/
        CvanBeuzekomCPPTestSuite.h
        libstdc++-6.dll

On the command line I run:

cd test
..\lib\cxxtest-4.3\bin\cxxtestgen --error-printer -o runner.cpp CvanBeuzekomCPPTestSuite.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? Please help.

best regards,

Fixed! The issue was running g++ with the flag -std=c++11. The flag that worked correctly is -std=gnu++11.
