How to create the fpc_crosswin32 deb

This deb was only tested under linux.

The base directory is $BuildRoot. Default value is ~/freepascal
  To change it use for example:
  []$ export BuildRoot=/home/user/freepascal

First get the FPC sources and the binutils.

For example:

  []$ cd <lazarusdir>/tools/install/cross_unix/
  []$ ./create_linux_cross_win32_deb.sh downloadbinutils downloadfpc buildbinutils

This will download the FPC svn to ~/freepascal/fpc, its install files to
~/freepascal/install and the binutils to ~/freepascal/binutils.

Create the fpc deb and install it:

  []$ cd <lazarusdir>/tools/install
  []$ ./create_fpc_deb.sh fpc ~/freepascal/fpc
  []$ sudo dpkg -i fpc-<version>.i386.rpm

Then build the fpc_crosswin32 deb and install it:
  []$ cd <lazarusdir>/tools/install/cross_unix/
  []$ ./create_linux_cross_win32_deb.sh buildcrossfpc buildcrosswin32deb
  []$ sudo dpkg -i fpc_crosswin32-<version>.i386.rpm

Now you can cross compile from linux to win32.
