Hello everybody,

Could we please stick to FPC related topics on this list? I don't think
that VPN connectivity and discussion about version control systems fit
this definition. Feel free to continue these discussions in the mailing
list fpc-other.

Thank you

It is probably possible to use git locally by an import of the CSV history
https://git-scm.com/docs/gitcvs-migration
and to fetch/push the changed files from/to the CSV server.

Not so easy, since the company version control uses CVS since many
years. Switching to something else is a major engagement...
Of course I could use something newer myself locally, but the idea is

I had to leave the RPi pascal/Lazarus stuff for a while, but now I am
checking the messages on the list again...

I agree on the tools side after trying to work on the RPi via TinyVNC
for a while...

- Version control
We use CVS at our company since 14-15 years, so I installed cvsnt on
the RPi in order to use that against our company server. I had done
this on a Linux Mint 13 virtual machine earlier.
Problem: With the Pi I did not manage to set up the VPN connection to
the company so I would be able to use it.
This is a showstopper.

- Copy/Paste
When asking about things here I wanted to copy code off the Pi and
paste it on my PC. But TinyVNC and Lazarus do not work well together
so if I Copy in Lazarus I have to first paste inside the VNC window
into a text editor, only then is it possible to also paste in the PC.
Inconvenient.

With a VMWare virtual machine it is possible to:
1) Share the host's VPN channel to the company so CVS works.
2) Copy/Paste in both directions
3) Drag-Drop files between the systems

So I think I will re-visit the Linux on x86 with cross-compilation
again. This I think was my path when I asked here first...
But I thought the cross-compile looked difficult to set up.
Maybe not now any longer.

If one goes Linux Mint, what version is the one I should choose to get
FPC/Lazarus working in the easiest way with cross compilation for
ARMHF?
I don't want to be on an unstable/unsupported distribution.

I use 32 bit OpenSUSE 13.1. And I strongly suggest to drop CVS and to use git 
instead. ;-)
There is even a git client GUI written in Free Pascal:

Sure but the accustomed development environment (tools, documentation, version 
control, useful links, mail and mailinglists...) must first be installed and 
maintained separately.
I find it much more convenient to use a single "every day" development 
environment for all tasks.

On the balance, particularly when one has something as capable as the 
RPi2, I don't. What I do find useful is being able to cut-and-paste 
between (programs running on) different hosts, which in practice either 
means running the IDE over SSH or having something running on each 
computer to implement a shared clipboard.

I thought we'd already been through this loop once? You need a custom

Mark, thanks for hanging in and advicing me!
Most appreciated!


Sorry but I've got other things that I've got to do so this is brief and 
might overlook points.



Right now I am getting dizzy by all the webpages, newsgroups, emails
and how-tos I have read the last week
And still I seem not to completely understand how this works...
But I hope I am getting closer.


You really should not be in a position where you have a working 
configuration and then can't get back to it. To be quite frank, you 
should be keeping (the equivalent of) an engineering notebook.



The tar file above does work on my RPi2 in order to build FPC from svn
trunk, so in what way is it not a valid ARM binary for the Pi?
Surely if it works on the Pi to build the bleeding edge trunk fpc
itself it should work in all other respects too??


Building the compiler does not exercise all aspects of the compiler, RTL 
and FCL. As a gross example, it does not exercise the graphical and 
database interface units which are referred to by Lazarus.



Or do I need to check out fpc svn sources from the 2.6.4 tag and build
the 2.6.4 compiler itself on the Pi hardware in order to get it
working correctly? If that is the case then fpc from tar seems not to
have something that an fpc from the same sources but compiled locally
will contain. And this something is not needed for compiling FPC?


Here's what I do. For any given architecture or- in the case of the RPi- 
variant of an architecture, try to find a binary that is tailored to it. 
In some cases that might be older (or newer) than the official stable 
release. Either get the fpcbuild bundle corresponding to that and build 
it, or in some cases you'll need to check a specified revision (etc.) 
out of svn. Compile that, noting any instructions you're given (e.g. if 
I remember correctly, for some early versions you had to warn the 
compiler etc. that it was to build the hardware float variant). Where 
feasible build other versions using the fpcbuild sources, except that 
trunk obviously needs to be built from svn; note that at present there's 
an fpcbuild for v3 RCx.


As I've noted in some detail in the Lazarus conf over the last few days, 
there's a preferred version of FPC for each Lazarus version, i.e. you 
can check out a tagged Lazarus release from svn and build it with a 
specific FPC. If running multiple versions you'll make life much easier 
for yourself if you make sure that Lazarus is always started off with a 
--pcp option.


Martin has gone to the trouble of making a binary available for the RPi. 
As I've discussed in this ML, there are problems with that on Raspbian 
Wheezy 2014 but these are just about fixed on 2015, much thanks to Jonas 
and others for setting me right on details relating to paths etc.  I 
can't remember where I've got to with Jessie.


So. I'd suggest that you start off with Martin's binary, build the 
matching 2.6.4, then build v3 RCx. On a PC, I've found Lazarus 1.4.2 OK 
with FPC v3 (RCwhatever), as I've said I can't remember where I've got 
to with Jessie.



My previous tests with svn versions were based on svn trunk sources
and FPC was compiled with this tar binary into the 3.1.1 version, then
this fpc 3.1.1 was used to compile Lazarus itself.

Anyway, I decided to try to go the apt-get route instead irrespective
of the webpage notes I found in several places stating that it does
not work for getting fpc and lazarus installed on an RPi2.


You decided based on whose advice exactly? Martin, myself and others 
have been telling you how to get things working... /repeatedly/ telling 
you how to get things working, then you go off on a tangent and complain 
that you've spent a day fruitlessly.


And to make it worse, you're complaining about fruitless work attempts 
on the Sabbath :-)

My previous tests with svn versions were based on svn trunk sources
and FPC was compiled with this tar binary into the 3.1.1 version, then
this fpc 3.1.1 was used to compile Lazarus itself.

Anyway, I decided to try to go the apt-get route instead irrespective
of the webpage notes I found in several places stating that it does
not work for getting fpc and lazarus installed on an RPi2.

So sudo apt-get install fpc lazarus gave me fpc 2.6.4 (again but in a
different location) and Lazarus 1.2.4 (pretty old but OK for now). No
error messages. :)

It also gave me a dialog when starting Lazarus (1.2.4) indicating that
in order to use multiple versions of Lazarus I had to add a command
line parameter --pcp  in order to direct it to where the
user configuration should be saved.
So I did this and created a new command line program, again based on
TCustomApplication, into which I copied the code from my previous test
with lnet. I also used the GetTickCount64 call as I had done before in
order to time the program operations.

Surprise! GetTickCount64() (and GetTickCount() for that matter) are
flagged as "Identifier not found" when I try to compile the test.

But after adding LCLBase to project required packages and adding
LclIntf to uses it solved the GetTickCount problem.
Now the test program compiles and runs. :)

So as far as I can see now I could move forward using the apt-get
versions.

Only problem is how to safely remove all of the various builds and
compiles and tar versions that are now scattered around my disk and
potentially will cause conflicts down the line.
IOW: How does one uninstall stuff that has been installed by make
install scripts?
Maybe I should make a clean start now that I know how to proceed, i.e.
scrap the SDcard and start over with a fresh operating system on a
card...

Last note:
Since I got Lazarus 1.2.4 off apt-get and it is pretty old now, could
I check out lazarus_1_4_4 and then build it using the fpc I have from
apt-get and thus have a newer Lazarus still using fpc 2.6.4?
Or does Lazarus 1.4.4 release need stuff that is in newer fpc
versions?

I am seroiusluy considering scrapping my current installation (FPC
3.1.1 and Lazarus 1.5) in favour of the released versions.
But I don't know how to go about it, i.e. how does one get rid of old
(newer) versions in favour of release versions?
In Windows one would do an uninstall, but here on Linux everything is
built from sources and might interact in unknown ways
I don't want to scrap my whole Raspbian installation this time around,
just get the released version for the Linux ARM platform.

BTW, I saw that the released Lazarus is 1.4.4, and I think that FPC
2.6.4 is the latest release. So since I have 2.6.4 installed it might
just be about changing the symlink inside /usr/local/bin to point
pparm to that versionon the FPC side?

Good suggestion!
I did this and fpc is now being built:
root@rpi2-jessie:/usr/local/fpc/source# time make all PP=ppcarm-2.6.4

Unfortunately it ends with an error:

/usr/local/fpc/source/rtl/units/arm-linux/cprt0.o: In function
`_haltproc_eabi':

If this can be solved:

Next question:
--
Do I need to also run the following commands afterwards:

 make install OPT=-dFPC_ARMHF PREFIX=/usr/local
 make install sourceinstall OPT=-dFPC_ARMHF PREFIX=/usr/local

and do these also need the PP=ppcarm-2.6.4 parameter?

You must always start with a released (currently 2.6.4) compiler. That 
is normal.


To do this, you can e.g. make a symlink to the 2.6.4 compiler (name it 
ppcarm-2.6.4) and use that when calling make:


make all PP=ppcarm-2.6.4

Except that that won't work on the RPi, where you need to start off with 
a specially-built compiler.


I think my 2.6.4 is OK because I got it as follows (from my notes):
wget
http://sourceforge.net/projects/freepascal/files/Linux/2.6.4/fpc-2.6.4.arm-linux.tar
tar xvf fpc-2.6.4.arm-linux.tar
cd fpc-2.6.4.arm-linux
./install.sh  (Reply /usr/local to the first question)


I thought we'd already been through this loop once? You need a custom 
binary tailored for the RPi.

Forgot to say that I am doing this on an ARM device (Raspberry Pi2).

To do this, you can e.g. make a symlink to the 2.6.4 compiler 
(name it ppcarm-2.6.4) and use that when calling make:


make all PP=ppcarm-2.6.4

or, if  you want to avoid the symlink, you can directly refer to the 2.6.4 
compiler:

make all PP=/usr/local/lib/fpc/2.6.4/ppcarm

(change the path to suit your setup, obviously)

I have always done the former.

Bo, look for the error message in Makefile and you'll also see reference 
to  OVERRIDEVERSIONCHECK  which allows you to build from your current 
compiler, i.e. something like


make OVERRIDEVERSIONCHECK=1 all

I'd not normally recommend this, but I think in the current case it's 
necessary and safe. TO EMPHASISE: UNDER NORMAL CIRCUMSTANCES USE THE 
LAST-RELEASED COMPILER.
