Hi,

i try to compile lazarus and i get a "make[2]: *** [lazarus] Killed". there is no more information about what error raised.

In dmesg i just get :
[495850.880000] select 1 (init), adj 0, size 61, to kill [495850.880000] select 8544 (dropbear), adj 0, size 109, to kill [495850.880000] select 9359 (ppcarm), adj 0, size 18768, to kill [495850.880000] send sigkill to 9359 (ppcarm), adj 0, size 18768

i compiled with this command: 'make clean all PP=ppcarm OPT="-dFPC_ARMEL -O- -dFPC_ABI_EABI" '
any ideas what it could be?

i don't need the hole ide. It would be enough if i could use ./lazbuild to compile projects. (or just: ppcarm)
is it enough to have "lcl/units/arm-linux" and
"lcl/units/arm-linux/gtk2" or do i need more units to compile gtk projects? it looks like these units are all compiled. (so do i need more? or should it be enough.)

thx
Beni

btw:

- yes i tried different versions of lazarus
- yes there is enough memory
- no hd is not full

i now tried to compile a project with the "lcl/units/arm-linux/gtk2" units. compiling worked without errors. when i try to start the programm i get an error.
maybe this and the "compiling lazarus error" is the same problem?

- yes there is enough memory

how much have you got? i got a crash the other day trying to make another locale by running localedef, and that was on 64MB of memory. had to make a swapfile for it to work.

try and compile your projects manually, without compiling the lcl first. something like this (you'll have to change the options):

#!/bin/bash

LAZ=/home/hcv/lazarus
LCL=$LAZ/lcl
UNIT_OPTS="-dlcl -dgtk2 -dlclgtk2 \
-Fu$LCL -Fu$LCL/interfaces/gtk2 -Fu$LCL/interfaces/gtk -Fu$LCL/widgetset \ -Fi$LCL/include -Fi$LCL/interfaces/gtk -Fi$LCL/interfaces/gtk2 -Fi. \ -FUbuild"

/usr/lib/fpc/2.3.1/ppc386 -B -O2 -CX -XX -Xs $UNIT_OPTS blank.lpr

and you should probably use -gl for the backtrace to be of any use.

henry

Try to apply patch from here: http://bugs.freepascal.org/view.php?id=13323

Best regards,
Paul Ishenin.

i got 128MB of RAM and i have a swap file of 250MB.

compiling the projects manually works fine.
no error from the compiler.

That would be all i need, but still the compiled programm don't run. I will now try the patch Paul Ishenin told me.

Beni

2009/4/15 Benedikt Schindler :

can you get a backtrace if you compile with -gl?

henry

Backtrace of a programm with just an empty window. programm was compiled with "-O- -dFPC_ARMEL -dFPC_ABI_EABI -gl"

i recompiled the hole fpc with the option "-gl" and the patch Paul Ishenin mentioned.
there is still a problem with programms, that wonna use windows. console prorgamms just work fine.

if i try to run a lazarus programm i get this backtrace.

2009/4/17 Benedikt Schindler :

hmm, this looks like the wrong syntax for ldrd, maybe it should be "ldr"?

henry

I don't know the arm instruction set, but this could be a deliberate illegal instruction to test what type of arm processor is used. If the processor doesn't issue an SIGILL, then the Move_pld procedure is used to implement system.move.

Vincent

What I think that happens is:
The constructor TGTK2WIDGETSET.CREATE fails somehow, unclear from this back trace, but probably before or in im_context:=gtk_im_multicontext_new;

The destructor is called which tries to cleanup im_context, which fails, because im_context has not been intialized correctly.

This particular crash may be prevented by using this destructor:
destructor TGtk2WidgetSet.Destroy;
begin
   if im_contextnil then
     g_object_unref(im_context);
   im_context:=nil;
   im_context_widget:=nil;
   inherited Destroy;
end;

Nevertheless, it doesn't solve the exception in the constructor on TGtk2Widget.

Vincent

2009/4/17 Vincent Snijders :

yeah, i think you're right. the in_edsp_test and cpu_has_edsp variables are used in the signal handler.

henry

i now use this destructor:

----------------------------------------------
destructor TGtk2WidgetSet.Destroy;
begin
if assigned(im_context) then
g_object_unref(im_context);
im_context:=nil;
im_context_widget:=nil;
inherited Destroy;
end;
----------------------------------------------

now there is no error for the destructor anymore.
But in the create there is still something bad. My error message is now:

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

The problem raises somewhere in the constructor TGtkWidgetSet.Create. The create constrcutor calls -> "PassCmdLineOptions; " PassCmdLineOptions calls -> "gtk_init(@argc, @argv)" gtk_init(@argc, @argv) raises the error.

backtrace dos'nt give very much
-----------------------------------------------
TGtkWidgetSet.Create - pass cmd line args (this is a debug output from me)
