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

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).

apt-get install fpc fpc-2.6.0 fp-units-gtk-2.6.0 fp-units-gnome1-2.6.0 fp-units-multimedia-2.6.0

It might give list of another packages, and then you can continue (example):

Code:

apt-get install fpc fpc-2.6.0 fp-units-gtk-2.6.0 fp-units-gnome1-2.6.0 fp-units-multimedia-2.6.0 libgtk2.0-dev libogg-dev libvorbis-dev libpango1.0-dev libcairo2-dev libc6-dev

Until it tells why it can't install them.
