[Lazarus] Help building Lazarus in Linux64

[José Mejuto]

Hello Lazarus-List,

I'm trying to setup an Ubuntu10/x64 machine with Lazarus SVN and fpc
SVN. For fpc SVN no serious problem, installed a basic 2.4.2 with rtl
and compiler from .deb and compiled the 2.5.1 SVN, and installed in a
folder under my home.

So fpc is installed in /home/joshy/pascal/fpcbin

And here is the problem, after solve the fpc.cfg location to be used
:) I try to make the Lazarus so used this line:

make bigide FPC=/home/joshy/pascal/fpcbin/lib/fpc/2.5.1/ppcx64

It stops with: [0.055] Can't find unit system used by AllLCLUnits
so I added the OPT=-va to see where it search the files. At the
beginning everything looks fine, with lines like:

[0.047] found source file name "alllclunits.pp"

but in the ppcx86 execution I saw something strange from my point of
view:

[0.047] Free Pascal Compiler version 2.5.1 [2011/01/06] for x86_64
[0.047] Copyright (c) 1993-2010 by Florian Klaempfl
[0.047] Path "/usr/lib/fpc/2.5.1/units/x86_64-linux/rtl/" not found

/usr/lib/... ????

A bit later everything starts to be "not found" messages :-?

What I'm doing wrong ? I can attach my fpc.cfg but I think it is right
and there is no reference to /usr/lib/ nowhere in the cfg.
