Windows中的Qt Creator-如何知道使用哪个编译器？

Question

I'm running Qt Creator 3.1.1 in Windows. I have an existing Qt project and I'm trying to add the Boost library to it. I think I have the .pro file configured to correctly point to the .lib and .hpp folders. However, I still get a linking error when I compile: "LNK2019: unresolved external symbol".

From other things I've read, it looks like I need to make sure that my Boost was compiled with the same compiler I'm using to compile my Qt projects.

Here's the Boost build I installed: http://boost.teeks99.com/bin/1.55.0/boost_1_55_0-msvc-12.0-64.exe

Here's a screenshot of my Qt Creator About window:

And here's a screenshot of my Qt Creator compiler options:

How can I tell which compiler I'm using? It lists a whole bunch, but isn't very clear about which one is actually used. Also, please let me know if this could be a simple 64 vs 32 bit problem.

You're looking at the QtCreator settings -- what you want is your project settings . In the left sidebar, click Projects.

At the top of the project pane, the selected build options for the current target appear in a little box at the top. Hover your mouse cursor over the down arrow for the compiler and debugger details, you'll see something like this:
