Hi,

i still try to get a gtk applicatoins running on my device. And now i have found a work around for one error message.

But in reality it's not a work around. It's a: "i didn't realy change anything, but it works now"
If i delete the changes again, the error raises again. So maybe someone of you have an idea where the real problem is.

----------------
Original File doesn't work. Error message is:
----------------

(process:24386): GLib-WARNING (recursed) **: gmessages.c:387: could not find handler with id `0' for domain ""
aborting...

-----------------
This one works:

if i delete the variable declaration (or the writeln), i have the error again.
Error raises at: gtk_init(@argc,@argv);

All of your workarounds have one thing in common: they cause an extra stack slot to be allocated (either via a local variable, or via an implicit temporary location allocated by the compiler), thereby changing the stack alignment by 4 bytes. Have your tried using the latest 2.3.1 compiler from svn? I fixed the stack alignment bugs on ARM in r13030 (on eabi, you need a stack alignment of 8 bytes, while the compiler only guaranteed 4).

my last svn update was 13 days ago.
I update my sources and recompile everything. (That will need some time) i give you a status update later.

THX !

Now all my problems just walked away.
What a bugfix for the compiler could do :)

My first test programm is now running without problems on the Openmoko Freerunner device.
@all: thx for the helping in the last 3 weeks.

good work! see if you can find somewhere on the wiki to put nice photos. arm devices outnumber x86 by a lot nowadays, so this is good news for fpc and lazarus.
