Fpc 2.2.0 and Lazarus 0.9.22: will they live together?
lazarus / 1-Linux

First of all, I'm a linux newbie.

Is it save to upgrade fpc (2.0.4), that is, replace 2.0.4 with 2.2.0
and still use the current stable version of Lazarus (0.9.22)?

(I mean do a rpm -Uvh on the new fpc .rpm files)

One might say, give it a try, but I'm not so keen on possibly f@#$ing
up my Lazarus version.

You will need to recompile Lazarus will fpc 2.2.0, you cannot continue
to use the Lazarus rpm.

There are reports that Lazarus 0.9.22 can be compiled with fpc 2.2.0.

IMHO it is save!

I managed to build lazarus-0.9.22 with fpc-2.2.0 create some rpms.

But note that lazarus' rpm will require 2.0.4, so a rpm -Uvh
fpc-2.2.0-0.rpm will not help if you use the official rpms.

What distribution are you using?

2.2.0 can compile Lazarus .22 just fine. Even latest FPC trunk can
AFAIK.

Alternatively, is it possible to setup Lazarus from SVN with Fpc
(2.2.0 or SVN) and keep my current Lazarus 0.9.22/fpc 2.0.4, so that
hey run independant from each other?

I manged to set up Lazarus from SVN with fpc 2.2.0 alongside Lazarus
0.9.22/fpc 2.0.4 in Windows, but that was a PITA as you can see here
and I know in windows version how to controll where (in what
directory) Laz and fpc are going to be installed, so they don't mess
up each other.

I guess I would have to download the source for Laz and Fpc (this is
something even I can do, once I've set up svn for my linux box).
But then what?
Build fpc and build Lazarus I guess, but how then to controll where
the are "installed" (this probably is not the right word in linux) and
to make this (and only this) Lazarus version I just build know that it
has to use the fpc version I just built?

(As a note. I tried to build an fpc from sources on windows, it built
just fine, but it (fpc.exe) then complained that it could not find any
unit (unless it was in the current active directory) at all, thus
rendering this build almost completely useless to me. Also the source
tree did not even slightly resemble the fpc source tree that comes
with the win32 Lazarus binaries, which would be a problem if I wanted
Laz to use this version.

I don't mind experimenting, I'm not afraid of having to do things from
the console, I don't care if the "unstable" versions crash or don't do
what I expect. I'm only concerned that I might screw up my current
stable Laz/Fpc combination or in some way mess up the package manager
(rpm, I have Suse), which would then later on become a problem if I
tried to install new stable versions using rpm.

This is getting a rather long post, I hope I did make myself clear.
I like this Laz/Fpc, and even though I'm just an amateur, I like to
contribute if I can to this project (and I succeded in fixing 1 or 2
minor issues).
