Then I built the RTL for linux, which also worked successfully, as far

but when compiling with -Tlinux, I now get the following message:
How did you build it? Building the RTL for Linux should be (assuming
that your FPC source is at c:\fpc)
cd c:\fpc
make crossall CPU_TARGET=i386 OS_TARGET=linux
CROSSBINDIR=C:\path\to\linux\binutils BINUTILSPREFIX=i386-linux-
BINUTILSPREFIX could also be something different or empty (then the
option should be "BINUTILSPREFIX="), it depends on how your
assembler/linker for Linux is prefixed.
Once that worked you can install the compiler using
make crossinstall CPU_TARGET=i386 OS_TARGET=linux
INSTALL_PREFIX=c:\wherever\fpc\should\be\installed
You should do a
make all install INSTALL_PREFIX=c:\wherever\fpc\should\be\installed
at first though. You'll also need to adjust a configuration for your new
compiler (simplest approach is to copy the fpc.cfg from
c:\whereever\fpc\2.6.2\bin\i386-win32\fpc.cfg to
c:\wherever\fpc\should\be\installed\bin\i386-win32 and adjust it)

that is: the system.ppu seems to be found, but there is something wrong
with the version.
You compiled the RTL using the 2.6.2 compiler, not the 2.7.1 compiler.
The PPU version of 2.7.1 is already > 160.
When trying to build the RTL for OS/2 (running make in the os2 subdir of
fpc/rtl), I get the following messages:
C:\fpc\rtl\os2>make
This is wrong. You need to build at the toplevel which is c:\fpc\rtl.
Everything else is not officially supported and not recommended for a
beginner (no offence).
(Note: You'd need to pass the path to the new compiler otherwise it will
just use "fpc" or "ppc386" which will use your installed fpc; this can
be done using the FPC option like this:
make clean all FPC=c:\wherever\ppc386.exe
)
C:/lazarus/fpc/2.6.2/bin/i386-win32/gmkdir.exe -p ../../rtl/units/os2

make (e=2): Das System kann die angegebene Datei nicht finden.

apparently, there is no i386-os2-as
You'll need to either find binary assembler and linker for OS/2 or build
it yourself. As I don't normally cross compile to OS/2 I can't help you
here.
when I did the same thing in the linux subdir, it worked (but: see above).
Do I need a special ASSEMBLER to build the OS/2 RTL?
Is it possible to download a pre-built OS/2 RTL?
You could try to use the RTL provided with the native OS/2 package, but
you'd still need an assembler and linker to compile a program.
No need to invest much time in those questions: I already had some
insights in the techniques of cross-compiling ... and in any case I'm
now able
to build a new compiler from the compiler sources.

Sven

mail or better use inline answers (like I did here). Thank you.
