QGIS » QGIS Application

I have found the problem by myself (and maybe the solution).

The file kpty.cpp in /qgis/src/plugins/grass/qtermwidget make a call to functions in utmp.h header of the GLIBC. setutent updwtmp & co...

In fact we don't have this functions in FreeBSD Headers.

So the solution is to copy/paste the code source of this functions in the ktpy file like in the attached file.

It's not beautiful but it works. I have can build install and use grass plugins without crash with this solutions.

Regards.

Still true fro current trunk?

Sorry, i was away from qgis for a time.

The bug is still true in the current trunk.

The solutions is the same :

QGis use some functions of the Glibc. If you see the man page of getutent & the others you have this disclaimer :

Portability Note: Although many operating systems provide a subset of these functions, they are not standardized. There are often subtle differences in the return types, and there are considerable differences between the various definitions of struct utmp. When programming for the GNU system, it is probably best to stick with the functions described in this section. If however, you want your program to be portable, consider using the XPG functions described in XPG Functions, or take a look at the BSD compatible functions in Logging In and Out.

You can also include the functions in other source code like this change i've made to compile with grass plugins on my FreeBSD :

Change in src/plugins/grass/qtermwidget/kpty.cpp :

--- src/plugins/grass/qtermwidget/kpty.cpp.orig 2010-08-24 18:47:22.000000000 0
++ src/plugins/grass/qtermwidget/kpty.cpp 2010-08-24 18:48:06.000000000 +0

#include "kpty_p.h"

#if defined(+FreeBSD)
#include "kpty_hack_for_bsd"
#endif

#ifdef +sgi
#define +svr4
#endif

New file in src/plugins/grass/qtermwidget/:
kpty_hack_for_bsd.h
kpty_hack_for_bsd.cpp

(this files includes functions getutent & other).

This solutions is sometimes used on BSD.

Also, i have add a path in the FindGRASS.cmake.

In the attach file (freebsd_patch_qgis.tar.gz) you have :

The diff file for FindGRASS.cmake with the 2 files (original and modified)
The diff file for src/plugins/grass/qtermwidget/ktpy.cpp with the 2 files (original and modified)
The new files in src/plugins/grass/qtermwidget/.
