Cross-compiling

One possibility is to use a PC, running Windows and Cygwin, to develop, compile, and test Classic AmigaOS programs, using WinUAE, before transferring them to a Classic Amiga. To cross-compile classic AmigaOS programs on Windows, there are two choices:

AmiDevCpp

To be completed later... when I take the time to try AmiDevCpp .
 

Cygwin and GCC

To cross-compile AmigaOS programs on Windows using Cygwin, you essentially need Cygwin and an AmigaOS cross-compiler and utils. So, you must have:

1. A Window-operated computer and Cygwin installed: Cygwin provides a good documentation so I won't repeat it here. I will assume that Cygwin is correctly installed and works. You should include some development tools as needed, for example Flex and Bison.
2. A cross-compiler: Zerohero provides everything that you need on this Web page, which provides all the details to install the cross-compiler without problems. Unfortunately, as of 2012/02/13, Zerohero's page is down, so I try to reproduce the steps as well as provide the required files below:
   
   1. Download the cross-compiler GCC v3.4.0 at m68k-amigaos-gcc-3.4.0.tar.bz2. Extract the content of m68k-amigaos-gcc-3.4.0.tar.bz2 into /usr/local/.
   2. Download the cross-compiler utils v2.14 at m68k-amigaos-binutils-2.14.tar.bz2. Extract the content of m68k-amigaos-binutils-2.14.tar.bz2 into /usr/local/.
   3. Download the LibNIX v1.2 libraries at libnix-1.2.tar.bz2. Extract the content of libnix-1.2.tar into /usr/local/.
   4. Download the IXEmul v48.0 libraries at ixemul-48.0.tar.bz2. Extract the content of ixemul-48.0.tar.bz2 into /usr/local/.
   5. At this point, in Cygwin, typing:

   /usr/local/amiga/bin/m68k-amigaos-gcc.exe -v
   

   should return:

   Reading specs from /usr/local/amiga/lib/gcc/m68k-amigaos/3.4.0/specs
   Configured with: ../gcc-3.4.0/configure 
                    --prefix=/usr/local/amiga
                    --target=m68k-amigaos
                    --enable-languages=c,c++,objc 
                    --enable-haifa
                    --enable-sjlj-exceptions
                    --disable-shared 
                    --disable-libstdcxx-pch
   Thread model: single
   gcc version 3.4.0
   

   Update 2016/01/10: if you receive:

   C:/Cygwin/usr/local/amiga/bin/m68k-amigaos-gcc.exe: 
   error while loading shared libraries: cygintl-3.dll: 
   cannot open shared object file: 
   No such file or directory
   

   then copy the file cygintl-3.dll into C:\Cygwin\bin.

   Update 2016/08/12: if you receive:

   configure: error: installation or configuration problem: 
   C compiler cannot create executables.
   

   then, it is well possible that you are missing the amiga library (libamiga.a) in /usr/local/amiga/m68k-amigaos/lib, so just check it out and add it if it is missing!

   6. Then, the following piece of code should compile and run on your classic Amiga or in WinUAE:

   #include <stdio.h>
   int main()
   {
       printf("Hello World!\n");
       return 0;
   }
   

   7.  Enjoy!
