[fpc-devel] Cross compiling with FPC 3.1.1 for win32+64

[kardan]

Hi,

Today I tried to crosscompile FPC on debian stretch following this
manual:
http://wiki.lazarus.freepascal.org/Cross_compiling_for_Win32_under_Linux

These are my first steps with FreePascal, so I welcome any help.

I used the zip for trunk which seems to be version 3.1.1 (rev 37618)
ftp.freepascal.org/pub/fpc/snapshot/trunk/source/fpc.zip
(are there signatures available?)

# 32bit
export INSTALL_PREFIX=/usr
export OS_TARGET=win32
export CPU_TARGET=i386
export fpcoptions="INSTALL_PREFIX=$INSTALL_PREFIX OS_TARGET=$OS_TARGET
CPU_TARGET=$CPU_TARGET" make all $fpcoptions
sudo make crossinstall $fpcoptions
# This fails with: Compiler /home/user/src/fpc/compiler/ppcross386 not
found.  Stop.
# FIX: `cd compiler; ln -s ppc386 ppcross386`
# Link the cross-compiler and place the link where Lazarus can see it.
sudo ln -sf /usr/lib/fpc/$fpcversion/ppcross386 /usr/bin/ppcross386

This seems to fix it, but using this compiling on our project i get the
following error:
Free Pascal Compiler version 3.0.4rc1 [2017/08/07] for
i386 Copyright (c) 1993-2017 by Florian Klaempfl and
others (1002) Target OS: Win32 for
i386 (3104) Compiling
fcllaz.pas Fatal: (10022) Can't find unit system used by

So in fact it uses the older 3.0.4rc1 version. When I try to build FPC
3.1.1 for my system, it fails:

$ make all
Makefile:2918: *** The only supported starting compiler version is
3.0.2. You are trying to build with 3.0.4..  Stop.

It went well without problems to compile FPC for win64 and create
an .exe for our project.

# 64bit
export OS_TARGET=win64
export CPU_TARGET=x86_64
export fpcoptions="INSTALL_PREFIX=$INSTALL_PREFIX OS_TARGET=$OS_TARGET
 CPU_TARGET=$CPU_TARGET"
make all $fpcoptions
sudo make crossinstall $fpcoptions
sudo ln -sf /usr/lib/fpc/$fpcversion/ppcrossx64 /usr/bin/ppcrossx64

I documented my steps here:

Next i will try with trunk.

Thanks for any hint.
