I am learning C++ and want a local offline C++ environment on my Mac without any IDE. I wrote a simple hello world program using Sublime Text and installed gcc. Now, if I do gcc filename.cpp, I get linker related error.
I tried running my code on Xcode and it works fine. I am able to run .c files, however.

c++ c xcode macos gcc
I am learning C++ and want a local offline C++ environment on my Mac without any IDE. I wrote a simple hello world program using Sublime Text and installed gcc. Now, if I do gcc filename.cpp, I get linker related error.
I tried running my code on Xcode and it works fine. I am able to run .c files, however.

GCC is a collection of different compiler for different languages. Each language have its own separate front-end program. For C it's gcc
, for C++ it's g++
.
They are actually almost the same, but g++
adds some options needed to build and link C++ programs (for example it automatically links with the C++ standard library, which gcc
doesn't).
So to solve your problem, if you're programming in C++ use the g++
program instead.
This works perfectly. Thanks!

GCC is a collection of different compiler for different languages. Each language have its own separate front-end program. For C it's gcc
, for C++ it's g++
.
They are actually almost the same, but g++
adds some options needed to build and link C++ programs (for example it automatically links with the C++ standard library, which gcc
doesn't).
So to solve your problem, if you're programming in C++ use the g++
program instead.
