Well I looked at the download page:
http://www.freepascal.org/download.var
and since my laptop has an Intel CPU I chose the one that said
Intel/i386...

But now I see that further down there is a section AMD64/x86_64, which
I did not use since it said AMD. But apparently that is the one for 64
bit. Sigh!
So how do I get rid of the erroneous fpc? I have no idea at all what
the install.sh script did so I can revert it
Is there an uninstall way? Here is where apt-get would have been good
since it has an uninstall function.

But, should not the 32 bit compiler work also in my Linux Mint 17
machine? Even though it has an Intel 64 bit CPU...

I am aware of some security stuff. And I asked myself often to do more 
security. For example disabling ssh on the machine. And some more.

But in some cases I need root acess. The location is secret and is deleted 
after the call. That's all I can do so far.

Only this application runs on the machine.

With 'setuid binary' I am not familiar.

[fpc-pascal] Can fpc 3.0 release be installed using apt-get on Linux Mint?

[Bo Berglund]

I have just created a VMWare virtual machine on my Win7 PC and
installed Linux Mint 17.2 Cinnamon in order to do some pascal
development.
I really do not want to build either fpc or lazarus myself, I just
want to use the released versions.

So is there a release 3.0 version available for Linux Mint 17 via
apt-get?
And if so what would be the correct command to get it?

I tried this:
sudo apt-get install fpc lazarus
It gathered info for a while, then asked if I wanted to continue.
When I looked at all the stuff it had printed on screen I found it was
about to install fpc compiler 2.6.2 and lazarus 1.0.10
So I aborted.

Is it so bad that new releases are no longer posted with current Linux
distributions?

The distro packages are not provided by us, but by the distributions
themselves and if there's no maintainer for the packages won't be updated
to newer releases...

No, none officially exists. There is a very old one, but it is not maintained.

I believe fpc 3.0 is in debian experimental, but it would be a very bad idea to 
use that in linux mint.

There is a command-line installer on the ftp site for fpc, after that you 
should build lazarus itself.

As it happens, I am currently writing an article on how to install lazarus on 
Linux mint 17.3 from zero.
It does describe compiling lazarus.

I can send it to you when it is finished.

Thanks, please do!
I bit the bullet and did the following, hopefully it is not way off
like my experiments on a Raspberry Pi2 were:

1) Went to http://www.freepascal.org/down/i386/linux-hungary.var 

2) Downloaded the "everything" file
ftp://ftp.hu.freepascal.org/pub/fpc/dist/3.0.0/i386-linux/fpc-3.0.0.i386-linux.tar

3) Extracted its contents to the Download dir

4) Then I entered the directory and issued the command:
sudo sh install.sh

5) During installation I was asked to select target and entered
/usr/local as I was told in another case some time ago.

6) Then I just replied Y to most of the questions and it installed
apparently just fine.
At least it responds to my fpc -h command...

Now I have to deal with Lazarus, but that is another list/forum...

That is the right way.

As an alternative you can install the FPC 2.6.4 deb (e.g. from the
Lazarus site), then download the FPC 3.0.0 sources and 'make install'
them.

> Now I have to deal with Lazarus, but that is another list/forum...

Lazarus needs libgtk2.0-dev, which should automatically install
libgtk2.0-common.

Lazarus 1.6RC1 will be available soon and it provides deb
packages for FPC 3.0.0 and Lazarus.

The nice think of the command line installer, is that you can install to
your $HOME directory as well. You do not require root permissions.

>

Use Git or SubVersion to checkout whatever version you want. On the
Github mirror, via the website, you can download a ZIP archive of a
branch too.

The simply do:

   make ide
or
   make bigide

depending on how much you want included by default into Lazarus. Once
you have a Lazarus executable, then you can build a new lazarus from
inside Lazarus (eg: when installing new components etc).

Been doing this process for 5 years and it never failed me.

I've used this method for years under Linux, FreeBSD and Windows. It
always works, and is really simple and quick. I highly recommend this
installation option to everybody.

I looked into my Raspberry Pi2 install notes and found these
dependencies for Lazarus:

Get additional packages:

apt-get update
apt-get install -y libx11-dev libgdk-pixbuf2.0-dev libcairo2-dev
gir1.2-coglpango-1.0 libpangox-1.0-dev xorg-dev libgtk2.0-dev
libpango1.0-dev

Are most of these superfluous? Is it enough with libgtk2.0-dev?

Then concerning Lazarus itself:

Get the Lazarus sources: 

svn co http://svn.freepascal.org/svn/lazarus/trunk lazarus

I found that I really would like to run on some form of fairly stable
source, so what would be the correct tag to use in place of trunk?

I have not tried on Linux-Mint.
Can you test?
If building Lazarus fails with a linker error you will see what lib is
missing.


> Will there be a tar package like for fpc

No.
Building Lazarus is easy (make all). The tricky part is helping the
user to install the required libraries.
If someone provides a script that checks the common distros and
maintains the script I would build such a tar.


> or should I go for an svn checkout?

I recommend that. This makes upgrading easy.

> Is there an RC tag for Lazarus?

Many. For example:

That's probably true, but you are mixing a Debian repository with
Ubuntu/Linux Mint/etc repository, which gives warnings and anyone you
are asking for help will tell you that it is a bad idea.

Debian is great at splitting packages into smaller packages.

Does Lazarus link with those packages?

I tried Linux Mint 17.3 64bit. After installing fpc x86_64 tar and
libgtk2.0-dev, Lazarus builds fine.
