I use fcpup to cross compile from Win64 to Win32 but failed. these was what I did:

1. download fpcupgui.exe, fpcup64.exe, CrossFPC_binutils_libs.7z from fpcup site.

2. rename fpcup64.exe to fpcup.exe

3. run fpcupgui.exe and successfully finished.
using fpc svn version 2.6.4
using lazarus svn version 1.2.2

4. run fpcupgui.exe to cross compile from Win64 to Win32 fpcurl=http://svn.freepascal.org/svn/fpc/tags/release_2_6_4 lazurl=http://svn.freepascal.org/svn/lazarus/tags/lazarus_1_2_2/ fpcuplinkname=""
lazlinkname=""
cputarget=i386
ostarget=win32
only=FPCBuildOnly,LazarusBuildOnly

5. then I go some error:

   fpcdefs.inc(160,2) Error: User defined: Cross-compiling from systems

without support for an 80 bit extended floating point type to i386 is not yet supported at this time

6. I found this on world:

http://free-pascal-general.1045716.n5.nabble.com/Cross-compiling-Win64-gt-Win32-fails-td5710399.html It says I need some files (/rtl/inc/sfpux80.pp and the files it includes) but I don not found in fpc source files

7. Please help me to solve this. I think this can be fixed, because the Lazarus has its lazarus-1.2.2-fpc-2.6.4-cross-i386-win32-win64.exe, So can I?

Please forgive my bad English, thanks!

FPC 2.6.x does not support cross compiling from win64 to win32 due to the error you found below.
AFAIR, it's been fixed in FPC trunk.

That's a cross compiler from 32 bit to 64 bit. I'd suggest doing the same with fpcup and using the 32 bit fpcup version to generate a 64 bit cross compiler which should work flawlessly.

Please forgive my bad English, thanks!

No problems at all with your English ;)

It's not supported in trunk either.

To clarify, there are two issues:

1. Lazarus IDE not behaving properly without SEH (openfiledialog crashing etc)
2. FPC not supporting xx => i386 crosscompiling due to the x86 codegen using extended which is not support on non x86. (needs softfpu)

That's a cross compiler from 32 bit to 64 bit. I'd suggest doing the same with fpcup and using the 32 bit fpcup version to generate a 64 bit cross compiler which should work flawlessly.

The Lazarus add on package (which allows the 64 bit IDE to compile 32 bit apps) technically is a normal 32 bit fpc, instead of a cross compiler. Only the ppc was renamed so it acts as if it was a cross compiler.
