Author: Richard Tew. Date: 28th January 2007 Email: richard.m.tew@gmail.com Website: https://www.disinterest.org/NDS/Python25.html Credits ------- Python requires little work for it to run on other platforms. If standard output is supported so that things like printf work and there is some method of input so that Python code can be entered and executed then most of the work is done. The rest is binding Python to the method of input and also filesystem. Most of the work was done already and the process of making this port involved linking that work together. These are the people to thank for that work: The cross-compiling environment devkitPro/devkitArm. https://sourceforge.net/projects/devkitpro Wntrmute The patches to Python 2.5 so that it can be cross-compiled. https://sourceforge.net/tracker/?func=detail&atid=305470&aid=1597850&group_id=5470 Han-Wen Nienhuys & Jan Nieuwenhuizen The keyboard interface and console for the Nintendo DS. https://headkaze.webpal.info/ Headspin. The filesystem support for homebrew devices. https://chishm.drunkencoders.com/gba_nds_fat/index.html Chishm Compiling --------- 1. Install the latest version of devkitPro. This should include: [ https://sourceforge.net/projects/devkitpro ] - devkitARM - msys - libnds - libfat (not used at this time) - dswifi (not used at this time) The devkitpro installer should download and install these for you. 2. Go to the MinGW web site and download and install in this order: [ https://mingw.sourceforge.net/download.shtml ] - msysDTK - MinGW - msys-autoconf (at least version 2.59) - msys-automake (at least version 1.8.2) You may need to take some initiative getting msys and mingw working. It didn't configure properly for me and I had to copy 'msys/1.0' over 'msys/' in order to get automake and autoconf into the path (the other folders in 'msys/1.0' are required to be on the same level as the binaries so it is not possible to add the 'bin' directories into the path). Then I had to install the updated versions manually. 3. Compile the zlib static library. a) cd NDSPython cd zlib-1.2.3 make This should build 'libz.a' then it will error when it tries to link something else. But that is not important as the static library is what we wanted. 4. Compile the Python static library. You need to have Python installed and to know the path to it in order to be able to cross-compile it. For me it is installed in '/c/Program\ Files/Python25' so replace that with your path to it. If your python is installed in the same location as mine, and all your settings are the same, then you should be able to use the same prebuilt 'configure' and 'Makefile'. a) cd .. cd NDSPython cd slp-250 export BASECFLAGS="-ffast-math -mthumb -mthumb-interwork -DARM9 -DNDS" export CFLAGS="-ffast-math -mthumb -mthumb-interwork -DARM9 -DNDS" export LDFLAGS="-specs=ds_arm9.specs -g -mthumb -mthumb-interwork" export CC_FOR_BUILD=gcc export PYTHON_FOR_BUILD=/c/Program\ Files/Python25/python sh configure --host=arm-eabi --config-cache b) make This should build 'libpython2.5.a' then it will complain about not finding 'getcwd' and error when linking something after that. But that is not important as you have the static library and 'getcwd' is provided by the NDSPython source code. 5. Compile the NDSPython rom. a) Alter low level linker settings so that Python gets enough stack on the Nintendo DS device to run. Edit this file: devkitPro\devkitARM\arm-eabi\lib\ds_arm9.ld Replace this altered section: MEMORY { /* original settings rom : ORIGIN = 0x08000000, LENGTH = 32M ewram : ORIGIN = 0x02000000, LENGTH = 4M - 4k dtcm : ORIGIN = 0x0b000000, LENGTH = 16K itcm : ORIGIN = 0x01000000, LENGTH = 32K */ rom : ORIGIN = 0x08000000, LENGTH = 32M ewram : ORIGIN = 0x02000000, LENGTH = 4M - 260k dtcm : ORIGIN = 0x023bf000, LENGTH = 260K - 4k itcm : ORIGIN = 0x01000000, LENGTH = 32K } b) cd .. cd NDSPython make c) Install support for your homebrew device using dlditool. For instance for the compact flash Supercard: dlditool sccf.dldi NDSPython.nds d) If your homebrew device is one which uses the 'ds.gba' roms, then you need to type 'make' again, which will take the 'nds' rom with your homebrew support and build another 'ds.gba' rom with that support. This should give you a usable compiled rom. 6. Install it on the Nintendo DS. a) Copy the NDSPython rom which works on your device somewhere on it. b) Copy 'NDSPython/NDSPython/python' to the root of your homebrew media. That is, the python directory found there should be placed directly in the root of your homebrew media. This is where NDS Python looks for it. You can test it works when you run NDS Python on your Nintendo DS by executing 'import slptest'.
