c++ command line compilation with gcc

Question

I am trying to use a text editor instead of code::blocks to write some c++ code. Just wrote a "hello world" program.

My code::blocks ide uses the gcc compiler that I installed, but I want to learn how to do it at a bit of a lower level. I read a few tutorials that said all I have to do is open a command prompt and type:

gcc helloWorld.cpp -o helloWOrld

but i get an error saying "gcc" is not a recognized anything.

What do i do to make it work?

Answer 1

Do g++ -Wall helloWorld.cpp -o helloWOrld... for your example

Answer 2

If you can compile with code:blocks, than probably it ships out with compiler.

You need to find a path to the compiler (probably somewhere in C:\Program Files\CodeBlocks...) The file name is something like mingw-gcc.exe or mingw-g++.exe I believe also, that you can find this path in IDE settings.

When you know the path and filename, just add the path to the system PATH variable and call gccfilename.exe

to compile c++ programms run g++filename.exe

Also you can run simple compilation without modifying PATH: just run "c:\Full path to compiler\compiler.exe"
