    I have a C project in VisualGDB, and now I’m adding some cpp files, so I need to add the flag -std=c++11 under CXXFLAGS , but I can’t find that option under VisualGDB Project Properties. I saw in other posts that you recommend using Additional Options (C++ files) under project properties > Configuration properties > C/C++ > Advanced. Should I just add the flag there? I need separate flags for C and C++.

    Thanks

    Hi,

    You can do that, but it could be easier to use the dedicated “Language Standard” setting. The exact name depends on the project type, but it would also be under Project Properties -> C/C++ -> Advanced.

    Thanks for the response. I have “Language Standard for C files” and “Language Standard for C++ files”. I specified c11 and c++11 respectively and tried to compile, but I’m getting this error:

    unknown type name ‘class’

    Do you know what could be causing the issue?

    I’m using VisualGDB 6.0R6 (build 5262) along with Linaro 4.9.4

    Sorry, that’s for you to figure out. Probably broken code somewhere.

    Thanks, I had to wrap a function with extern "C", it’s working now.
