Invalid floating point operation - Environment option window

[dajashby]

I have installed fpc 2.0.2 and lazarus 0.9.14 on a AMD 64 running Kubuntu Dapper Drake beta. (Living dangerously, I know). The fpc was the x86_64 binary version.
...
When I try to access the Environment options Lazarus tries to display a window, which then crashes with the error "Invalid floating point operation".  The following appears in the terminal window

TApplication.HandleException Invalid floating point operation

This is caused by fpc bug 5010:  http://www.freepascal.org/bugs/showrec.php3?ID=5010

The fpc bug report claims that this only exists with 2.0.3, but I'm using 2.0.2. [/quote]
This bug is in fpc 2.0.3 and fpc 2.0.2, but you can indicate only one version in the bug tracker. fpc 2.1.1 doesn't have this particular bug.

Lazarus compiler with fpc 2.1.1 has other issues:
http://www.lazarus.freepascal.org/mantis/view.php?id=1971
and
http://www.lazarus.freepascal.org/mantis/view.php?id=1972
So that is not a good option either

So far it isn't allowing me to edit environment and editor options.  Is it possible to do this by editing config files - I want to point lazarus at the fpc source files and change the editor font in order to make the product even slightly usable.

You can edit the ~/.lazarus/envirionmentoptions.xml file.

Does the bug have any futher manifestations?

Not that I know, but it can happen anywhere where controls are layout.

Also - what's the deal with the unreadable tooltip windows?

No idea, what you mean. Maybe it is a font issue. Try to find a good gtk1 theme (and I have no idea what I am a talking about, since I am hardly a linux gui user).

Vincent,

Have you been editing my post again?  How do you do that?

I have now succeeded in installing fpc and lazarus on my trusty old Pentium III server that is currently running Kubuntu 5.10, so I suspect that the bug might be only an issue with 64-bit fpc. The problem with the tooltips went away when I changed to a different font that Lazarus told me was a 2-byte font (presumably a Unicode font?)

I wonder if 'd run into any trouble if I installed a 32-bit fpc on the AMD machine, and compiled lazarus using that?

:oops: I am sorry, it never happened to me before, except now twice in  your case. The edit button is next to the quote button. :oops:

Maybe, because that will create 32 bit application and you will need 32 bits (gtk) libraries on a location that the compiler can find. So you might have to edit the library path in /etc/fpc.cfg.

Yes, but I only get edit buttons on my own posts...

Hmmm, yes, I can see that would be a problem.  I guess I'll just wait until someone fixes it.  Meanwhile, I think the fpc/lazarus combination is so much better than Kylix!
