Hi, I'm playing with OpenBsd 5.4 amd64 (with XFCE4) and found it has an fpc 2.6.2 package, so I tried compiling Lazarus trunk.

I had only a couple of issues while compiling.

1) Use gmake instead of make. This is the same as in FreeBsd, no problem.
2) Had to create the file ide/include/openbsd/lazconf.inc with the same contents of the FreeBsd version (attached).
3) At linking lazarus there were some warnings:

/usr/local/lib//libglib-2.0.so.3600.1: warning: vsprintf() is often misused, please use vsnprintf() /usr/local/lib//libglib-2.0.so.3600.1: warning: stpcpy() is dangerous GNU crap; don't use it /usr/X11R6/lib//libX11.so.15.2: warning: strcpy() is almost always misused, please use strlcpy() /usr/X11R6/lib//libX11.so.15.2: warning: strcat() is almost always misused, please use strlcat() /usr/X11R6/lib//libX11.so.15.2: warning: sprintf() is often misused, please use snprintf()

4) When I've tried to run ./lazarus, I got this:

(lazarus:14292): GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed [FORMS.PP] ExceptionOccurred
Sender=EAccessViolation
Exception=Access violation
Stack trace:
$000000020D8F7A4A
TApplication.HandleException Access violation
Stack trace:
$000000020D8F7A4A
[FORMS.PP] ExceptionOccurred

I think this can be related to my gtk2 version: gtk+2-2.24.20p1

Well, I hope someone can take a look at the OpenBSD version, this is a really nice O.S. that deserves a Lazarus package :).

Regards,

Thanks for the hint. I added that.

Lazarus sources don't use them directly. Maybe some FPC packages use them.

Run in gdb. Hopefully it gives a better stacktrace.

Thanks for testing.

If you run ./lazarus --g-fatal-warnings, it will halt on a GTK warning, so you can get a backtrace under gdb.

Hi Henry, attached is the backtrace (gdb.log). I don't see anything obvious, maybe the problem is fpc related (I'm using 2.6.2).-- Leonardo M. Ram?http://leonardorame.blogspot.com

I think the named libs use them, not us.

#7 0x0000000000b038ce in GETSTYLEWITHNAME ( WNAME=0x1ae7258 "vertical scrollbar") at gtk2proc.inc:7815

That is
        StyleObject^.Widget := gtk_vscrollbar_new(nil);

That means a normal gtk call fails.

Probably there was some other bug happened prior to this and crumbled the heap or stack.
Please compile with more checks. For example:

make clean all OPT='-Criot -ghtl'

Hi Mattias, I've compiled with OPT='-Criot -ghtl', here are the results if I run from gdb:

Program received signal SIGBUS, Bus error.

The program is running. Exit anyway? (y or n) % ? lazarus ./lazarus --g-fatal-warnings

Here's the result of just running from the command prompt:
