Properties menu item is gone

If you are on a mac, make sure to have the XCode command line tools installed (search for that on the internet on how to do it).

Then create a "Hello World" C++ project using the project wizard and see if that compiles and runs.

If not, then your C++compilation infrastructure is insufficient.

If you use homebrew, you might need to add /usr/local/bin to the runnnig Cevelop's Environment through the global preferences...

It’s very annoying that the console wipes itself, so I have to pay close attention and I can not cut&paste you the evidence. Trust me: it is using the wrong compiler. 2. How can I change the compiler back? I think I did that through File > Properties, but that menu refuses to come up. How can I reset that? Victor.

1. The build console is probably not wiped, but hidden by the output console. You can cycle through the consoles using the "Terminal" icon in the console view. If you don't want the consoles to switch on output you can toggle the corresponding buttons:
   

2. There should be a File -> Properties entry. I don't know why this menu entry could vanish and have never experienced Eclipse CDT removing it by itself. However, you can customize your perspective. Window -> Perspective -> Customize Perspective.... In the Menu Visibility tab, you can tick the properties entry:

In the properties of your project you can configure the compiler command: Properties -> C/C++ Build -> Settings -> Tool Settings (Tab) -> GCC C++ Compiler -> Command:

If you are on a mac and just have XCode and its command line tools install, it comes with clang that disguises as gcc, i.e., it is callable as g++ while still being clang. So selecting the GCC toolchain will give you the clang compiler regardless.

If you use homebrew to install gcc under /usr/local/bin, you have to go to the Top-level menu Cevelop C++ IDE->Preferences->C/C++->Build->Environment and Select... the PATH environment variable and adjust it to have /usr/local/bin before all other paths:

With that the GCC toolchain actually uses gcc. Sorry for confusing you by saying "properties" and not being clear but I was on the phone and not my computer when replying. You can also set that environment project specific by using the C++ project's properties.

That’s because I made a change, but I can’t find where I did this. Victor.

Never mind. I’m giving up on this. I can’t even get a file compiled.
