Re: arm port plans for the squeeze cycle (fpc bootstrapping)
>free pascal needs bootstrapping.
I started trying with roughly the following recipie (note: these should
be equivilent to what I did but I also went down a lot of dead ends, did
things in a less sensible order etc)
wget
ftp://ftp.freepascal.org/pub/fpc/dist/arm-linux-2.2.2/fpc-2.2.2.arm-linux.tar
tar -xf fpc-2.2.2.arm-linux.tar binary.arm-linux.tar
tar -xf binary.arm-linux.tar base.arm-linux.tar.gz
tar -zxf base.arm-linux.tar.gz lib/fpc/2.2.2/ppcarm
mv lib/fpc/2.2.2/ppcarm .
tar -zxf base.arm-linux.tar.gz bin/fpc
mv bin/fpc .
apt-get source -b fpc
<install all missing build-depends except those with a fp- prefix>
export PATH=$PATH:$PWD
tar -zxf utils.arm-linux.tar.gz bin/fpcmake
mv bin/fpcmake .
cd fpc-2.2.4/
<apply the attatched patch to debian/rules (note: this is a work in
progress, I have not written the conditionals to make it suitable for
other architectures as well)>
dpkg-buildpackage -B -d
By doing this I managed to get the rtl to build but the compiler failed
to build with
/root/fpcdeb/ppcarm -Ur -Xs -O2 -n -Fuarm -Fusystems
-Fu/root/fpcdeb/fpc-2.2.4/fpcsrc/rtl/units/arm-linux -Fiarm -FE.
-FUarm/units/arm-linux -dRELEASE -dFPC_ARMEL -CfSOFT -darm -dGDB
-dBROWSERLOG pp.pas
i_linux.pas(596,11) Error: Identifier not found "abi_eabi"
i_linux.pas(596,11) Error: Illegal expression
i_linux.pas(539,11) Fatal: There were 2 errors compiling module, stopping
Fatal: Compilation aborted
And when I asked about that error (on #fpc on freenode) jonas-fpc said
"plugwash: use fpc trunk for arm eabi, 2.2.4 contained many bugs even if
you get it to compile"
So IMO the thing to do is to wait for the next major release of
freepascal before trying further to introduce it to debian armel. This
mail serves to document the path I have taken so I or somone else can
continue once a suitable fpc version is in debian.
