Ubuntu 13.10 Install Lazarus/FPC and everything else needed to make it
all work.
lazarus / 1-Linux

----------------------------------------------------------------------

EDIT  See my last post  for the solution that made it work.

Hi,
  I've been trying to install Lazarus/FPC on Ubuntu 13.10 x86_64 for
the last 2 hours without luck.
  I won't go into the problems I've been having matching/configuring
the IDE and compiler etc.  But I'm totally confused now as what I
need.

  I just went to SF and downloaded lazarus_1.0.14-0_amd64.deb. When I
tried to install it, it told me I didn't have FPC, so I downloaded
fpc-2.6.4.x86_64-linux.tar and ran the install.sh script.  Then, in
accordance with the readme, I then went into the example/text folder
and compiled the hello program and ran in successfully.  I checked its
time-stamp to make sure the executable was created by me.
  So now I went back to install lazarus_1.0.14-0_amd64.deb, but it's
still complaining:
Code: [Select]user@HOME:~/Downloads/Lazarus$ sudo dpkg -i
lazarus_1.0.14-0_amd64.deb

Then I found this page on SF : Lazarus - Browse /Lazarus Linux amd64
DEB/Lazarus 1.0.14 at SourceForge.net and remembered that I also have
to install FPC-SRC, so I downloaded the deb package from that page:
fpc-src_2.6.2-0_amd64.deb, and when I tried to install it, I got the
following error:
Code: [Select]user@HOME:~/Downloads/Lazarus$ sudo dpkg -i fpc-

Errors were encountered while processing:
 fpc-src_2.6.2-0_amd64.deb
It was then that I realised that the version of FPC-SRC didn't match
the FPC version, and that Ubuntu already had v2.6.2 on it.  So I tried
to find a 2.6.4 version of FPC-SRC but haven't been able to do so.

Could someone please help me by explaining what steps are required to
install this correctly with the latest stable version of the IDE and
Compiler.  I'm prepared to start fresh again by removing the packages,
downloading new ones etc.   The sticky post in this sub-forum is
dated, and I cannot find a FAQ that explains how to do this.

Cheers,
Nap

I use Debian, but Ubuntu should be about the same.

Remove EVERYTHING Lazarus in your system. Use locate or similar to
make sure you get it all. Do the same with FPC.

Once it is clean, you have to make a choice. Install from svn, install
from your distro's repositories, or install from the Lazarus
sourceforge files (precompiled). Changing later tends to cause
problems.

I have no idea how up-to-date your distro's respositories tend to be,
but if they don't have Laz 1.2 they are out of date. If that is the
case, I suggest using Laz's current 1.2 .deb release from sourceforge.

You should also make a choice for FPC. Personally, I get FPC from my
distro's repositories and Laz from sourceforge. In either case, it is
easiest to install FPC first, then Laz. If you get Laz from
sourceforge, you MUST pin (lock) the installation or your package
manager may overwrite your Laz installation, right now or at a later
date. Do it before you run apt-get update or a graphical package
manager equivalent. If you get FPC from sourceforge, you will probably
have to pin that too.

The main web page http://www.lazarus.freepascal.org
has a "Download Now" button that leads you to the 3 needed packages:
FPC, FPC sources and Lazarus.
The latest version is Lazarus 1.2.

----------------------------------------------------------------------
bylaardt · 2014-03-27 16:59

Install FPC 2.6.1 first.
the standart FPC in ubuntu is the 2.6.0 version

Correct is: Sorry, my mistake: install  2.6.4 first.

----------------------------------------------------------------------
marcov · 2014-03-27 17:10

The current version of FPC is 2.6.4.  2.6.2 is over an year old, and
2.6.0 is ancient.

Thanks for answering so quick!!

lazarus 1.0.10_dfsg-1 and fpc 2.6.2-5 (which I think was already
installed) are what's available from the Software Center.   When I
tried using this Lazarus, it found the IDE and SRC but couldn't find
the compiler, and then complained about version numbers in the file
name when I found the link to it.  That's why I decided to try other
ways of installing it.

That's quite a task, especially since I don't know specifically which
files belong to those packages.   I used the commands shown in this
post @ Stackoverflow (see below)
Code: [Select]sudo apt-get purge fpc lazarus
sudo rm -Rf /usr/lib/fpc
sudo rm -Rf /usr/lib/lazarus
sudo rm -Rf /usr/share/fpcsrc
sudo rm -f ~/.fpc
sudo rm -Rf ~/.lazarus

sudo apt-get autoremove lazarus fpc
sudo apt-get --purge remove lazarus fpc
sudo apt-get autoremove
sudo apt-get autoclean
sudo apt-get -f install
sudo dpkg --configure -aBefore I attempted to install other versions. 
Is they sufficient?  Any further advice?

I removed a bunch of FPC related files but I'm not sure of those in

There are some Lazarus & FPC files in:
/var/cache/apt/archives/    and    /var/lib/dpkg/alternatives/
I assume it's ok to leave those as they are just part of the package
database?

I don't mind pinning the versions I have, just want it to work first. 
But thanks for the advice.  I knew you had to pin Lazarus but wasn't
aware of the need to do FPC as well.

From what I understand, the IDE must be the right version for the FPC
installed.  So, how does installing Lazarus 1.2 go with FPC 2.6.2-5? 
Is 2.6.2-5 a higher version than 2.6.2?  And what about FPC 2.6.4, is
there no FPC-SRC available for it?

Also, what is the significance or cause of this error (from the second
error msg I posted in the OP):
Code: [Select]trying to overwrite
'/usr/share/fpcsrc/2.6.2/rtl/nativent/tthread.inc', which is also in
package fpc-source-2.6.2 2.6.2-5

I am using laz 1.2 from sourceforge with fpc 2.6.2-8 from the Debian
repo. So, far I haven't run into any problems that I can attribute to
not having fpc 2.6.4. However, that doesn't mean there aren't any. 

The -5 in 2.6.2-5 is simply that package maintainer's way of
identifying his latest build of 2.6.2. It is still FPC 2.6.2.

Delete everything lazarus and fpc with your package manager.

Then sudo locate lazarus | grep lazarus/ which will show all remaining
lazarus directories.  Delete them all, including their contents,
except those in /var/cache/apt/archives if you prefer to keep them. 

Edit: You probably don't want to delete any laz or fpc package that
you downloaded from sourceforge and intend to install, otherwise, you
will have to download it again.

Do the same thing with fpc.

Run locate again without grepping anything to see if there are any
random laz or fpc files hanging out. Delete them too, unless you have
an overriding reason to keep them.

You should now be able to install without running into problems.

----------------------------------------------------------------------
fpcoder · 2014-03-27 18:42

Nappe, you just need to download three files and run sudo dpkg -i
*.deb
Remove the stuff you installed. Download as usual the DEB's for latest
release of fpc, fpc source and lazarus. Put them all in your home
folder and it will install everything in one sweep.

I learnt this from: http://lazplanet.blogspot.se/2013/03/how-to-
install-lazarus.html

Seems to show how to get rid earlier install too. I cut out the
relevant part:

"If you already have lazarus installed then uninstall it first:

Press Ctrl+Alt+T to open a terminal. Run the following commands:

        sudo apt-get purge fpc lazarus
        sudo rm -Rf /usr/lib/fpc
        sudo rm -Rf /usr/lib/lazarus
        sudo rm -Rf /usr/share/fpcsrc
        sudo rm -f ~/.fpc
        sudo rm -Rf ~/.lazarus

Now we are going to install Lazarus. Type cd  followed by a space.

Drag the folder (inside which you have saved the 3 .deb files) in the
terminal window. Press enter.

Then run:

    sudo dpkg -i *.deb


You will probably see a message saying that some library is not
installed (such as libgtk2.0-dev). Install the dependent libraries.
For example,

    sudo apt-get install libgtk2.0-dev

Then run the above command again

    sudo dpkg -i *.deb

Now it is going to install. It takes a bit of a time. It will require
almost 1.5 GB of space in your linux partition to install Lazarus in
Linux.

To run lazarus you can use the dash menu or on a command prompt run
"startlazarus".

Unfortunately, the various installation packages differ somewhat in
where they install to. The above is not necessarily the exact case and
can't be trusted.

Thanks for the info, didn't know that. But I would run the commands
anyway, and after that run the grep you described to check if it
worked.

----------------------------------------------------------------------
Napoleon · 2014-03-28 05:30

Thank you all.
I have deleted everything Laz & FPC related (and I hope nothing
more)...  So I'm ready to install again.

But, one more question which wasn't answered earlier.

I haven't been able to find fpc-src greater than 2.6.2.  If I install
fpc2.6.4 what do I do about the fpc-src?  As I understand it, fpc &
fpc-src must match to allow the debugger to step through all the code.

@Rails:  I guess going with 2.6.2 is not a problem then, but what
about pinning the versions?  Would I be locking myself out of
something that's just around the corner? Earlier this month Kamischi
said (in another thread here) : QuoteGive me a day or two and the fink
packages for fpc 2.6.4 and lazarus 1.2 are ready.

MiSchi

P.S. fink packages are out. GO GO GO!
Anyone know where can I get them?

Cheers.

*Edit:  Added info and rephrased my post.

----------------------------------------------------------------------
BigChimp · 2014-03-28 09:58

fink is for OSX, not for Ubuntu.
You can unpin stuff later if you want to and if necessary, no problem,
so you're not locking yourself out.

Yes, fpc and fpc src *must* match. 2.6.2 is ok as current lazarus
stable 1.2 is built with that.

----------------------------------------------------------------------
Napoleon · 2014-03-28 12:58

Done 

Having followed the advice concerning removal of all things Lazarus
and FPC, I still had problems installing.  So I did the following:
dpkg --get-selections | grep -v deinstall >
installed_packages_passX.txt  and then searched the output file for
Laz and FPC.

For each Laz/FPC package mentioned;  (I also found a package called
lcl-1.0.10 (and a few derivatives) that needed to be removed too.)
Initially I did:
sudo dpkg -r <package>   (for some I used -P)
But some packages couldn't be removed due to dependencies.  So I tried
all of them, then looped back over them and got rid of a few more.

Having previously deleted a lot of files manually, I invariably broke
the 'lazarus' package and was told I had to reinstall it, but it
couldn't find the archive.  This also broke my Software Center for a
while. So for this one, I did dpkg --remove --force-remove-reinstreq
lazarus (which fixed my Software Center too).

Eventually dpkg --get-selections | grep -v deinstall >
installed_packages_passX.txt stopped showing me Laz & FPC packages but
I still couldn't install.  So I got rid of the filter and used: dpkg
--get-selections > all_installed_packages.txt

Now I had a shorter list of packages to remove, and I decided to use
sudo apt-get remove --purge <package> to remove them.

One by one I removed all of them, repeating the dpkg --get-selections
> all_installed_packages.txt command to refresh the list each time.

With everything gone, I was able to install Lazarus 1.2.0 with FPC
2.6.2 (and fpc-src 2.6.2).

startlazarus worked fine, and this time  the IDE was able to find all
the bits it needed.

I hope I don't have to do this dance again.

Job Done!!  Now I can do what I really want to do.

Thanks for the support and advice gentlemen.

Ouch, that should have been removed automatically by the purge.
Obviously it wasn't.

Some distros build Laz as a bunch of small packages, instead of one
large package. It can be really confusing when they also change the
package names. They sometimes also build FPC as multiple packages. I
find it easier to find this stuff using the graphical package manager
Synaptic, which makes it a snap to search both on name and
description. 

But good to know that you now have a working installation.   Quote

I use Synaptic for that (Package/Lock Version command).  As far as I
know, Synaptic has its own internal mechanism for locking and doesn't
rely on apt/preferences.
