<pre wrap="">I'm modifying the lazarus packaging scripts to make building debs of
lazarus, fpc and cross-fpc variants simpler than it is. (Cross is not
simple right now)
I've read the buildfaq (thanks Marco) and various fpc build scripts but
am still puzzled in this respect:
Why does:
$ cd fpc
$make clean all OS_TARGET=win32 FPC=/usr/bin/ppc386
make:
./compiler/ppc386.exe
I thought I was building a cross-compiler, not cross-compiling one - or
is it a side effect of building the rtl etc?

The thing you are missing (read buildfaq better :-) is that FPC doesn't have
to be cross for platforms on the same architecture.

I used 386-win32 for testing the script because FPC-SVN won't compile
for arm-wince - I'll try a ppc build for the test then.<br>
<br>
So... because the makefile knew it was compiling for the same
architecture it decided that I wasn't building an fpc cross compiler
but cross building an fpc compiler? That's a bit unexpectedly clever...<br>

So... this time:<br>
$ make clean all CPU_TARGET=powerpc OS_TARGET=linux FPC=/usr/bin/ppc386
BINUTILSPREFIX=/usr/bin/powerpc-linux-gnu-<br>
<br>
And, just like before, it has created a load of powerpc binaries:<br>
<br>
$ file /tmp/fpc_patchdir/fpc_build/usr/bin/postw32 <br>
/tmp/fpc_patchdir/fpc_build/usr/bin/postw32: ELF 32-bit MSB executable,
PowerPC or cisco 4500, version 1 (SYSV), statically linked, stripped<br>
<br>
<br>
So I'm still puzzled that the recipe for creating a cross compiler is
actually cross-compiling a compiler and cross-compiling the tools.<br>
<br>
Of course, compiler/ppcrossppc was created, but it seems as a
precursor to creating all the powerpc binaries.<br>
<br>
So I still think I'm doing it wrong; was my make command line correct
to produce an fpc instance that will cross-compile for powerpc-linux?<br>
