ARM GCC is probably the ideal, low cost C/C++ compiler

for gp32 dev. It's not the fastest ARM compiler available,

but it is free. Here is v1.1 of a crt0.S and lnkscript

that I wrote for gcc for the gp32



  http://www.devrs.com/gp32/files/gcc/



 It is designed to work with ported official libs or with a

setup that uses no official libs.



1) Make a directory for installation of this gcc package.

  For this example, we will use c:\bin\gcc304 but this

  will be reference below as %rootdir%\gcc304



2) Get FireFly's GCC 3.0.4 port from here and unzip it

  in the directory we just created:



    http://darkfader.net/gp32



   This is a generic ARM C/C++ compiler for windows. It is

  optimized for ARM9 by default.



3) Copy the file arm-elf-objcopy.exe from directory:

     %rootdir%\gcc304\bin

   to the following directory:

     %rootdir%\gcc304\arm-elf\bin

   Now rename the new copied file to the following:

     objcopy.exe



   This will make it easier later when we are compiling files.



4) From here http://www.devrs.com/gp32/files/gcc/libs/ get the

  following files:

    crt0.o crtbegin.o crtend.o user_init.o

  and put them into the following directory:

    %rootdir%\gcc304\arm-elf\lib\gcc-lib



5) Now install the official libs that have been ported to gcc.

  These are all the files from http://www.devrs.com/gp32/files/gcc/libs/

  that have the following format: lib*.a



   I prefer to install these in c:\bin\gp32lib as a central location

  so that I can use multiple C compilers, for testing code on each

  compiler. However, if you only plan to use one C compiler, you may be

  successful by copying them to the following directory:

    %rootdir%\gcc304\arm-elf\lib\gcc-lib



6) Using a text editor (windows NOTEPAD will work) modify your

  autoexec.bat file to contain the following line. Putting it at the

  bottom of the file will work:

    SET PATH=%rootdir\gcc304\arm-elf\bin;%PATH%

  (REPLACE %rootdir% WITH YOUR ACTUAL PATH NAME!!)

  Save the file & exit text editor.

 

7) Reboot your computer so the autoexec.bat changes will take effect.



8) Get one of the example files from http://www.devrs.com/gp32/files/gcc/

  and unzip it in a new folder. Get to a command line interface (open a

  DOS window if using win95/win98) and type the command MAKE to compile

  the example.
