Cygwin setup
Cygwin is a Linux-like environment for Windows. It can be used to cross-compile Linux applications for RISC OS.
Setting up Cygwin
Setting up Cygwin is fairly straight forward. Download and run the installer from the Cygwin homepage. Following the default setup will probably be OK, although it's advisable not to install it in a directory tree that uses a space (such as C:\Program Files\). Choose a suitable mirror and make sure that the following (binary) packages are installed. (Most are found under the "devel" tree. Alternatively, choose "Full" view for an alphabetical list of all packages.)
If you prefer the command line, you may find it easier to install packages there instead of the fiddly Cygwin GUI. To do this people have written scripts called apt-cyg or cyg-apt, with syntax like:
apt-cyg install bison
(or the same for cyg-apt). You can install both with:
cd /usr/local/bin wget http://stephenjungels.com/jungels.net/projects/apt-cyg/apt-cyg wget http://lilypond.org/~janneke/software/cyg-apt chmod +x apt-cyg cyg-apt
Type the command name on its own for full details of how it operates. Cygwin needs packages wget, tar, gawk and bzip2 for apt-cyg, and also Python for cyg-apt so if you have trouble use the GUI to check those are installed.
Cygwin uses the DOS command window by default, which isn't so good for things like scrollback or cut and paste. If this annoys you you may find installing rxvt helps - try these guides [1] [2] [3].
Required packages for GCCSDK
For GCC 3.4.6:
- autoconf (version >=2.5)
- automake (version >=2.5)
- binutils,
- bison
- flex
- gcc
- gcc-core
- gcc-g++
- gperf
- make
- subversion
For GCC4:
- autoconf - must be version 2.5 (Watch out as the cygwin installer will try and automatically install a more recent version every time it is run.)
- autogen (This is currently (January 2008) not available via the cygwin installer - see below)
- automake - must be version 1.9 (Be careful as the cygwin installer will try to install 1.10 every time you run it, as it is a dependency of libtool.)
- diffutils
- gcc
- libtool
- make
- makeinfo
- patch
- subversion
For the autobuilder:
- cvs
- gettext-devel
- glib
- libpopt0
- patch
- pkg-config
- unzip
- xorg-x11-bin
If any of these are missing or you need to make changes, you can re-run the Cygwin setup program at any time. Once this is done, running Cygwin from the Start menu or Desktop icon will present the "bash" console.
It's also worth noting that virus checkers can slow down build processes considerably, since the build emits lots of temporary files and the virus checker insists on checking each one.
If you're not familiar with unix commands it might be worth doing a bit of research with Google. To get you started, you could try:
