So, what is the best way to use Win 32 and 64-bit, in my case?
I would suggest: don't go the most complicated route ever ;-)
It's really dead simple to get cross compilation with Windows as target to
run. In your case I would suggest the lowest common denominator: the 32bit
compiler. So build from/for 32bit and add the 64bit cross compiler there:
I assume the official FPC 2.4.4 release for 32bit to be installed under
C:\FPC\2.4.4.
set PATH=C:\FPC\2.4.4\bin\i386-win32;%PATH%
cd C:\FPC\2.5.1
svn co http://svn.freepascal.org/svn/fpc/trunk src
cd src
make install INSTALL_PREFIX=C:\FPC\2.5.1
make crossinstall INSTALL_PREFIX=C:\FPC\2.5.1 OS_TARGET=win64
CPU_TARGET=x86_64
make clean
Done. Now you set the compiler (in Lazarus) to
C:\FPC\2.5.1\bin\i386-win32\fpc.exe and switch the target architecture/OS in
the project options depending on your needs - the 32bit fpc.exe will then
either invoke the 32bit ppcx86.exe to compile for 32bit, or the 32bit
ppccrossx86_86.exe to compile for 64bit.
One small addition to your solution:
copy C:\FPC\2.4.4\bin\i386-win32\fpc.cfg C:\FPC\2.5.1\bin\i386-win32\
<Edit the copied fpc.cfg and replace all "2.4.4" with "2.5.1">
I use $fpcversion but thanks anyway. ;-)
Right... I always forget that this is available... Then ignore the
second part, but the first one is necessary :D
Regards,
Sven
