Installing snapshot version on Ubuntu

[Dibo]

Hello,
Trying to install a snapshot version but I have problems with the detection of FPC. These are my steps:
1. Downloading fpc-src_2.2.4-20090705_i386.rpm, fpc_2.2.4-20090705_i386.rpm, lazarus_0.9.27.20793-20090705_i386.rpm
2. Converting RPM to DEB packages using Alien
3. Then installing fpc-src, fpc and lazarus.

The installation process is going without problems, but when I start Lazarus I have an error "the Free Pascal compiler (filename: fpc) was not found." Once I had the same error on Windows, but then, in Enviromnent Options I set path to fpc.exe. I am a novice Linux user and I do not know where to look for FPC

Ubuntu version 9.04

Try
The compiler path in

/usr/bin/fpc

Once downloaded the latest snapshots package fpc, fpc-src and lazarus, and it looks like everything installed correctly. But this time I have a strange error while compiling a empty project. First, I have the error:
"Can not find contnrs unit used by Masks"
When you add this module I have another error:
"Can not find unit used by fpimage Graphics"
When you add this module, can not find another, and so all the time. What's happening? Is this a bug of snapshot version or is something wrong with my configuration?

May be there a conflict with an anterior fpc version.
check paths in /etc/fpc.cfg
In the line
# searchpath for units and other system dependent things
-Fu/usr/lib/$fpcversion/units/$fpctarget
-Fu/usr/lib/$fpcversion/units/$fpctarget/*
-Fu/usr/lib/$fpcversion/units/$fpctarget/rtl

In my case is /usr/lib/fpc/2.2.2/units/i386-linux

Check in Compiler Options the correct Widgetset LCL, if you have a gtk2 not  instaled or compiled, rebuild LCL with GTK2.

It is no better with win32 snapshots. It takes next to nothing to get errors that unless you have expert status offer little clue as to what may be the true cause.
As a newbie this issue seems probabilistic. If there are 1000 files any one of which will generate failure then 99.99% accuracy is required to have a chance of seeing anything useful. The best opportunity, if you are like me and can't yet fix it yourself, is to wait for a tested release.

check paths in /etc/fpc.cfg

# searchpath for units and other system dependent things
-Fu/usr/lib/$fpcversion/units/$fpctarget
-Fu/usr/lib/$fpcversion/units/$fpctarget/*
-Fu/usr/lib/$fpcversion/units/$fpctarget/rtl

Hm, I can't find fpc.cfg file. I'm totally beginner user of linux. Search engine can't find it too.

[clauslack]

fpc.cfg must be in /etc directory, if not exist, you can recreate it with fpcmkcfg.

Just run fpcmkcfg, and then check the paths in fpc.cfg.

Thanks to all! I have not fpc.cfg file, so I created it from samplecfg. As in your case clauslack, I had to replace the path "user/lib/fpcversion" per "user/lib/fpc/fpcversion". In addition, I had to get other libraries as lX11 and lgdk_pixbuf but I found the solution here in the forum. Once again, thanks.
