New page

This tutorial shows you how to compile a C/C++ program in windows using Eclipse and MINGW. '''MINGW''' stands for "Minimalist GNU for Windows". Remember that GNU is the linux-based compiler and hence if we want to use it for Windows, we have to have certain executable(s) to be running in Windows.

== Development Package ==
You can get the same development package as the one we promote for ARM processors.
# Get the Development Package and unzip in your C drive
#: '''[https://sourceforge.net/projects/armdevpkg/files/: SourceForge SJSU Development Package]'''
#: '''It is important to NOT unzip at your desktop'''
#: '''The unzipped path should not have spaces'''
# Get 32-bit Java
#: If you have 64-bit Java installed, uninstall it and get 32-bit Java.
 

== Open Eclipse and Create New Project ==
{|
|
'''1.''' Open Eclipse.
    Always open the MINGW batch file since it sets up environment variables for you.
| [[File:mingw_open_eclipse.png|left|frame|Open MINGW bat file in your development package directory]]

|-
|
'''2.''' Create a new C/C++ Project
 
* Go to '''File''' --> '''New''' --> C++ Project
* Name your project anything you want, preferably without spaces.
* Choose '''Executable''' --> '''Hello World C++ Project''' and '''MINGW GCC'''
* Then click '''Finish'''

|-
|
'''3.''' Write your source code
    Copy the simple source code on the right.
|
<syntaxhighlight lang="c">
#include <stdio.h>

int main(void)
{
/* Without this, printf() will not work */
setvbuf(stdout, 0, _IONBF, 0);
setvbuf(stdin, 0, _IONBF, 0);

/* Write rest of your code here */
printf("Hello World\n");
return 0;
}
</syntaxhighlight>

|-
|
'''4.''' Run your program
 
* First, build your program by going to '''Project''' --> '''Build Project'''
* Now, go to '''Run''' --> '''Run'''
* The output will appear in the '''Console''' tab below.
| [[File:mingw_run_project.png|left|frame|Run your project]]

|-
|
'''4.''' Optional : Debug your program
 
* To perform debugging or run your code one line of code at a time, you can perform debugging.
* Now, go to '''Run''' --> '''Debug'''
* Your program will now "pause" at the '''main()''' function.
* You can now use the '''Run''' menu to execute one line at a time.
* Other hints :
*: Double clicking on the code window sets a breakpoint.
*: You must press the red stop button to stop your program.

== Hints & Troubleshooting ==
* '''How do I run FreeRTOS simulator ?'''
*: The easiest method is to use one of the existing projects. Open up '''Win32_Mingw_Tasks''' and write your source code there.
*: If you want your own dedicated project, you can copy and paste that folder, and '''IMPORT''' this new project into eclipse
* '''Eclipse is unable to write to the executable'''
*: It is possible that your program is already running, so terminate it using the Windows Task Manager
