Lazarus 0.9.30 can't recompile in Ubuntu
lazarus / 1-Linux

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

This problem has started after I installed the last version of Fortes
Report. I couldn't install additional packages, the compiler returns
errors like : printers unit not found...
When I remove Lazarus completely and installed it again from .deb
packages, it works, but I get the same problem when I've installed
Fortes Report.
I remove Lazarus again, and downloaded from trunk 0.9.31, but it
failed to compile TurboBird source.
Then I remove it and tried to install 0.9.30 from .deb package after
deleting .lazarus folder.
Now it failed to recompile, I get this error:

masks.pas(29,22) Fatal: Can't find unit contnrs used by Masks

I tried clean installation, installing without packages, withtout
luck.
any body knows how to solve this?
I'm using FPC 2.4.2 and Ubuntu 11.4

Thanks

i encountered this on windows. it was due to missing or corrupted
fpc.cfg or some cfg file.

Which directory contains the configuration in addition to .lazarus?

please help, I'm running out of Lazarus

This error often happens due to fpc version mix up.
You probably have files from several fpc versions (ppu files from fpc
itself).

The fpc config points to where they should be, but it may point wrong.
IIRC there was recently some mails that fpc sometimes creates a wrong
fpc.cfg...
http://bugs.freepascal.org/view.php?id=19538

fpc.cfg can be in different places.
/etc/fpc.cfg
in your home dir, and some other places

find which fpc is called by lazarus (in case more than one exist)
create a simple program.pas, and then something like this
fpc -va program.pas | grep fpc.cfg


you can also specify -va in lazarus, to see where fpc is looking (but
it's a lot of output)

I've removed Lazarus, and FPC and all fpc.cfg files, and installed
Lazarus 0.9.30.0 again, when I recompile using clean I get:

Fatal: Can't find unit Contnrs used by Masks

Run "make clean all" on cmd line in the Lazarus directory.
Later you can use the Build Lazarus dialog.

Don't forget to erase "~/.lazarus/" folder.

I get the same error in command line:
/bin/rm -f units/i386-linux/alllclunits.ppu
/usr/bin/ppc386 -gl  -Fu. -Funonwin32 -Fuforms -Fuwidgetset
-Fu/usr/lib/fpc/2.4p

Fatal: Compilation aborted
make[1]: *** [alllclunits.ppu] Error 1
make[1]: Leaving directory `/usr/lib/lazarus/0.9.30/lcl'
make: *** [lcl] Error 2

in project's compiler otpions test button I get this warning:
no fpc.cfg found
now I can not run new applications

I experienced the same problem a couple of days ago, when I
uninstalled fpc 2.4.2 and installed 2.4.4.

Now I will delete fpc, install it again, so I hope I will remember
where exactely the problem was. Please wait, I'll post here soon.

Now I installed FPC 2.4.4, it works fine, except for Turbo Bird cann't
compile it returns:
/usr/bin/ld: warning: link.res contains output sections; did you
forget -T?

but Lazarus re-compiles successfully
Thanks all

removing *.o, *.ppu, and *.a solving the problem of Turbo Bird.
Now every thing seems good
Thanks

This problem happens often and there are many possible reasons for it.
Mattias Gärtner has written a wiki page about it. Please check out:
