Re: [Announce] Free Pascal Compiler on extras-devel
 
I have no clue why you want to ignore dependencies of nicely packaged thing, so I can't tell if it's safe.

Otherwise, instead of ignoring them, I would just re-package it to optify more things (if possible).

:( what to do ?

This is about not-properly working repositories. Packages are working. Today it seemed that repositories are working good, and I got this installed.
1) enable sdk-repository
2) enable extras-devel
3) update
4) install fpc

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:

I have the same problem that Necrofenser has, what i could do to fix it?

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).

Please, could you tell me what i have to do tu install properly fpc on my n900 step by step, i really need fpc for my studies

What happens if you then run:
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
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.

I believe that i have problems with SDK repository because i couldnt update repositorys when SDK are enable, when i run
Code:

apt-get install fpc fpc-2.6.0
its say me
Code:

E: Malformed line 6 in source list /etc/apt/sources.list.d/hildon-application-manager.list (absolute dist)
E: The list of sources could not be read.

Did you know what i have to do to fix it? thanks in advance

Re: [Announce] Free Pascal Compiler on extras-devel
 
Open (in vim or leafpad) this file (/etc/apt/sources.list/hildon-application-manager.list) and see whether you see anything wrong in line 6
Best wishes.

"Malformed line" really means that line is broken. Fix/remove it.

SDK-line should be:
Code:

deb http://repository.maemo.org/ fremantle/sdk free non-free
Use copy/paste.
