Hi,
I downloaded and extracted both 0.9.30 and 0.9.30.2RC sources. I have
FPC 2.4.4 installed (both binary and sources)
I issue a make clean all, compilation finishes successfully. But when
I try to start lazarus, I get these.
Code: [Select]
(lazarus:15521): GLib-GObject-CRITICAL **: g_object_unref: assertion
`G_IS_OBJECT (object)' failed
[FORMS.PP] ExceptionOccurred
  Sender=EInvalidOp
  Exception=Invalid floating point operation
  Stack trace:
  $00007FDC9A24F684
TApplication.HandleException Invalid floating point operation
  Stack trace:
  $00007FDC9A24F684
[FORMS.PP] ExceptionOccurred

I am on Archlinux 64, FPC compiles programs successfully and I can run
them. (I only tried simple command line examples though)
What can be wrong?
Thanks.

I had similar problems. Try:
Code: [Select]make distclean

EDIT: This error is after ./lazarus or ./startlazarus ?

Thank you Blaazen, I tried your solution but no joy. The same error
appears after I run both lazarus and startlazarus.
I'll try the compiled snapshots tonight. But I'm beginning to suspect
my computer configuration. I use Archlinux 64 on both my machines (A
laptop with Turion64 x2 and a desktop with Athlon II X4) Only the
laptop has this error. I compiled both 0.9.30 and 0.9.30rc2 on my
desktop, they ran fine.

I have 64-bit Chakra Linux (based on arch + KDE4) on laptop and I use
SVN for both fpc and Lazarus. I had that message firstly only for
./startlazarus and later for both ./lazarus and ./startlazarus and
"make distclean" did the job. Do you have GTK2 ?

http://www.archlinux.org/packages/community/x86_64/lazarus/

packages on Arch community repo....

You can just do
sudo pacman -S lazarus

why do you need to compile yourself?

@Blaazen: I tried make distclean, but the result is the same.
@FabienWang: I knew about the package, but since pacman installs it in
/usr/bin and /usr/lib, it takes root priviliges to install components
which I don't like. Anyway, I had already tried to install before I
posted and the error messages were the same. It seems there is
something missing.

If you're using gtk2-2.24-7 then downgrade to 2.24-6 and it'll work.
