Tutorial 1: Create a C/C++ project

In this tutorial, you'll create a simple Makefile project.

You use the New Project wizard whenever you create a new project in the IDE. Follow these steps to create a simple "Hello world" project:

To open the New Project wizard, from the workbench main menu, select File > New > C Project
Name your project (e.g. MyFirstProject).
In the Project type list, expand Makefile Project and select Empty Project.
Select the QNX toolchain to build and execute on QNX Neutrino.
A toolchain represents the specific tools (such as a compiler, linker, and assembler) used to build your project. Additional tools, such as a debugger, can also be associated with a toolchain. Depending on the compilers installed on your system, there might be several toolchains available to select from.
Click Next, then Finish.

The IDE creates your new project in your workspace. Your new project shows in the Project Explorer view. If a message box prompts you to change perspectives, click Yes.

If you don't see your project, click on the Project Explorer tab.

Next, you'll create a Makefile for your project.
In the Project Explorer view, highlight your project.
Click the New C/C++ Source File button on the toolbar:
Name your file Makefile, make sure the Template is set to <none>, then click Finish.
Double click on your new file to open it in the editor and write what you need in the file.
Here's a sample Makefile you can use:
```
CC:=qcc 
all: hello 
hello: hello.c 
clean: 
        rm -f hello.o hello
```
Note: Use Tab characters to indent commands inside of Makefile rules, not spaces.
When you're finished editing, save your file (right-click, then select Save, or click the Save button in the tool bar).
Finally, you'll create your hello world C (or C++) source file. Again, click the New C/C++ Source File button on the toolbar, select Source File and the Default C source template, and name your file hello.c.

Open the file and write your "Hello world!" program.

Your hello.c file might look something like this when you're done:

#include <stdlib.h> 
#include <stdio.h> 

int main(int argc, char *argv[]) { 
   printf("Hello, world!\n"); 
   return EXIT_SUCCESS; 
}

Congratulations! You've just created your first Make C/C++ project in the IDE.

For instructions about building your program, see the section Building projects in the Developing C/C++ Programs chapter.

Note: In order to run your program, you must first set up a QNX Neutrino target system. For details, see the "Preparing Your Target" chapter.
