Chapter 4. Programming with Cygwin

4.1. Using GCC with Cygwin

4.1.1. Console Mode Applications

Use gcc to compile, just like under UNIX. Refer to the GCC User’s Guide for information on standard usage and options. Here’s a simple example:

Example 4-1. Building Hello World with GCC

C:\cygnus\>

C:\cygnus\> gcc hello.c -o hello.exe

hello.exe

Hello, World

C:\cygnus\>

4.1.2. GUI Mode Applications

Cygwin allows you to build programs with full access to the standard Windows 32-bit

API, including the GUI functions as defined in any Microsoft or off-the-shelf publication. However, the process of building those applications is slightly different, as you’ll be using the GNU tools instead of the Microsoft tools.

For the most part, your sources won’t need to change at all. However, you should remove all __export attributes from functions and replace them like this: int foo (int) __attribute__ ((__dllexport__)); int foo (int i)
