[fpc-devel] Cross-compiling Linux x86_64 -> Win32

[Maxim Ganetsky]

Hello.

I am trying to set up cross-compilation from Linux x86_64 to Win32 and 
have the following problems:

Case 1. Using FPC 3.2.0.

I installed the following:
fpc-3.2.0-x86_64-linux.tar
fpc-3.2.0.i386-linux.tar
fpc-3.2.0-i386-win32.cross.x86_64-linux.tar

Installation process finished successfully without warnings.

And with this setup I get the following result:

$ make bigide OPT="-V3.2.0 -vut" OS_TARGET=win32 CPU_TARGET=i386 
LCL_PLATFORM=win32
make -C packager/registration

Note the warning "Path "/usr/lib/fpc/3.2.0/units/i386-win32/rtl/" not 
found".

Indeed there should have been system.ppu which is missing and therefore 
compilation fails. Why is this directory was not installed?

Case 2. Using FPC 3.2.2.

I don't see i386-win32.cross.x86_64-linux for FPC 3.2.2.

What is the recommended way to cross-compile with it?
