i have been told that my gcc is out of date but i do not know how to update it, if i do gcc --version i see 4.2.1 and if i do clang --version i see 9.1.0, i tried installing a updated version through homebrew but i cant get qt to use it and i still get the above error, i also tried switching it to clang for both c and c++ and got the same error above.

if anyone has any more advice please let me know thanks

The move() template method didn't appear in the STL until C++-11. If your compiler isn't fully C++-11 compliant, then code using this won't compile. Your only solution is to try to find a C++-11 compiler -and- a C++-11 version of the STL.

Note that you also need to set the C++ compiler flags -std=c++11, -stdlib=libc++, and -mmacosx-version-min=10.7

is it possible to update the compiler?

I do Mac builds with gcc 4.2.1 and the compiler options I showed above. It is possible I don't exercise the same parts of boost or STL as your code (since templates aren't instantiated unless used), but I don't see errors related to boost or STL. You probably need to update your C++ Standard Library, not your compiler.

well i managed to get past all the errors and get the project compiled, i have now moved on to a new one and am getting the following errors, also thank you very much for all your help!

You haven't #include-d the QStyle header file into whatever file it is you are trying to compile. Your "multisenddialog.h" or "ui_*.h" file forward-references the class with a statement like "class QStyle;", which tells the compiler that a class by that name exists, but until you include the actual QStyle header file, it has no idea what that class looks like.

You need to spend a little time learning to use the toolchain you are trying to build your projects with.

[luke9511]

i managed to get three different projects compiled however the version of openssl i used will cause issues down the road, so i tried using a different version and go this error
