    VSC not working on MacOS
    When trying to compile a simple program I am getting this error using Visual Studio Code on my MacBook Pro. Trying to avoid using Pico as my editor because it sucks. Please help!

    eph525@Anthonys-MBP MAE 2360 % g++ Test.c
    clang: warning: treating 'c' input as 'c++' when in C++ mode, this behavior is deprecated [-W
    Undefined symbols for architecture x86_64:
    "_main", referenced from:
    implicit entry/start for main executable
    ld: symbol(s) not found for architecture x86_64
    clang: error: linker command failed with exit code 1 (use -v to see invocation)
    eph525@Anthonys-MBP MAE 2360 %

    My code is this:


    int main()
    printf("Hello world");
    return 0;

    A couple of things. You are writing a C program and should be using 'gcc' to compile it. 'g++' is used for C++ development.

    My version of your Hello World application is:
    #include <stdio.h>
    int main(void) {
        printf("Hello World\n");
        return 0;
    I compile with
    gcc -o hello hello.c
    Not providing the '-o' option means you get a.out which can be confusing.

    Now, I did use 'g++' to compile my code and beyond that (correct) warning, it did compile and run.

    The fact that you are getting the other errors means that you don't have the command line build tools install, ensure you do so with
    xcode-select --install
    You should then have the C Library necessary to run your program.

    You should also likely install Xcode which is an awesome IDE for for your development needs. You can write programs in C, C++ and Objective-C for macOS, iOS, WatchOS and so on in there.
