Free Pascal Compiler [1] version 2.4.4 [2] is now on extras-devel [3]. It contains packages:
Code:
fpc-2.4.4           - Free Pascal - SDK-2.4.4 metapackage
fp-compiler-2.4.4   - Free Pascal - Compiler
fp-units-rtl-2.4.4  - Free Pascal - Runtime Library
fp-units-2.4.4      - Free Pascal - base units
fp-utils-2.4.4      - Free Pascal - Utils
Compiler and units-rtl are needed for compiling. Units contains big set of units/packages [4] packed in one debian-package, you need it if you want do 'anything non-trivial'.

Packages are optified, if you are interested in to compile Pascal on N900-device. You need binutils installed, because it needs additionally 'as' and 'ld' [5].

--------
Usage: hello
#install (to scratchbox)
Code:
apt-get install fp-compiler-2.4.4
make file
Code:
program Hello;
  begin
  writeln ('Hello, world.')
end.
Compile it with
Code:
fpc hello.pas
(With sb2, use sb2 -e fpc hello.pas)

Copy to device and run, no additional dependencies on phone (I don't know why "rtl"="runtime library", because it is not needed on phone).

--------
Usage2: gles-2.0 test
#Install also units (~70M unpacked)
Code:
apt-get install fp-units-2.4.4
wget http://cc.oulu.fi/~rantalai/gles20demo.pp
fpc gles20demo.pp
--------
Some technical
All maemo specific is on own git [6].

As you might know the FPC compiler is written in Pascal, so getting it on Maemo repository [7] needed some tricks. There were several approaches:
* Crosscompile it. E.g. i386 fpc can produce arm-binaries. This is kinda tricky with autobuilder.
* Use older version of FPC
-Make binary-only-package (on non-free-repository) which contains fpc-binary.
-Bundle old fpc-binary with sources.

I used last option (you can try another ones). This is not big deal, because it is used only for first round of compiling, then it is compiled second time with new compiler. So at the end, resulting binary (fpc-2.4.4) is always compiled with fpc-2.4.4. Drawback is, that package can only be used with arm, i386 and x64 (it contains those pre-compiled binaries).

It seems, that compiler on fremantle autobuilder is not handling x86 targets.

It will give linking error for every library I have tried, e.g.
Code:
/scratchbox/compilers/cs2007q3-glibc2.5-i486/bin/sbox-i486-pc-linux-gnu-ld: cannot find -llua5.
Easiest workaround is (on debian/rules)
Code:
ifneq (,$(findstring arm-linux,$(DEB_BUILD_GNU_TYPE)))
    make
else
    touch name_of_binary
endif
and then, of course, packages are useless on x86.

New upstream version: fpc-2.6.0 on extras-devel.

Install package fpc-2.6.0 and you will get everything you need.

---------
Just for notes: Repackaged from Debian Sid.

Code:
wget http://ftp.de.debian.org/debian/pool/main/f/fpc/fpc_2.6.0.orig.tar.gz
wget http://ftp.de.debian.org/debian/pool/main/f/fpc/fpc_2.6.0-3.debian.tar.gz
tar xvf fpc_2.6.0.orig.tar.gz
tar xvf fpc_2.6.0-3.debian.tar.gz
rm fpc_2.6.0-3.debian.tar.gz  fpc_2.6.0.orig.tar.gz
mv fpcbuild-2.6.0/* .
rmdir fpcbuild-2.6.0/
echo "1.0" > debian/source/format

sed -i 's/Build-Depends: debhelper (>= 7), fp-compiler, fp-units-base, fp-units-fcl, fp-utils,/Build-Depends: debhelper (>= 5), fp-compiler-2.4.4, fp-units-2.4.4, fp-utils-2.4.4,/g' debian/control
sed -i 's/Build-Depends: debhelper (>= 7), fp-compiler, fp-units-base, fp-units-fcl, fp-utils,/Build-Depends: debhelper (>= 5), fp-compiler-2.4.4, fp-units-2.4.4, fp-utils-2.4.4,/g' debian/control.in

sed -i 's/Build-Depends-Indep: hevea/Build-Depends-Indep:/g' debian/control
sed -i 's/Build-Depends-Indep: hevea/Build-Depends-Indep:/g' debian/control.in
(I just got bored with script-like instructions)
Add to debian/rules
+FPCMAKE=/opt/fpc/bin/fpcmake
(because last version (2.4) was optified).


debian/rules
Foreach:
-mv -t foo bar
+mv bar foo
-cp -t foo bar
+cp bar foo
(as builders cp and mv are out dated)

debian/rules
Skip making of documentation, just empty package. Because it is using 'hevea', which is difficult to package (because it needs ocaml).

debian/control
remove 'Breaks' (as dpkg in sb1 doesn't understand it (and it is not funny to use dpkg --force-depends, when apt-get would be easier)).

debian/control
For fp-units-gfx-2.6.0: no depends on libsvgalib.
For fp-units-multimedia-2.6.0: depends on liba52-0.7.4-dev, no a52dec-dev
For fp-units-multimedia-2.6.0: no depends on libdts-dev

I don't know if you are aware of it, TxPad has ObjPas(FPC) and Delphi syntax highlighting(and is written in Lazarus/FPC), so its useful for people using this...

Its sources are also useful because they have Maemo specific workarounds and problems solved..

Thanks for the package(s) btw

TRX.

When i try to installfpc-2.6.0 package i get this error:

Code:
home/user # apt-get install fpc-2.6.0
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
  fpc-2.6.0: Depends: fp-units-gtk-2.6.0 (>= 2.6.0-maemo4) but it is not going to be installed
             Depends: fp-units-gnome1-2.6.0 (>= 2.6.0-maemo4) but it is not going to be installed
             Depends: fp-units-multimedia-2.6.0 (>= 2.6.0-maemo4) but it is not going to be installed
E: Broken packages

You need first add SDK repository:
Code:
root 
echo "deb http://repository.maemo.org/ fremantle/sdk free non-free" >> /etc/apt/sources.list.d/hildon-application-manager.list
apt-get update
apt-get install fpc-2.6.0
But it needs 45MB from rootfs (it warns about 120MB) as this is primarily targeted for used by autobuilder. Last version (2.4) contained more optification.

I enabled extras-devel and the SDK repository as shown above but when I try 'apt-get install fpc-2.6.0' I get the following:
Code:

Is there a way to tell apt-get to ignore the broken dependencies ?
I don't think I need those gtk thingies.

Would it be safe ?
I only have 64MB left on rootfs.
