[solved] Lazarus-SVN, GTK2 und Linken

[Targion]

Hallo!
Ich hatte über diese Sache schon eine längere Diskussion mit Vincent im Bugtracker, dort konnte das Problem allerdings nicht verifiziert werden.
Also, könnte mal jemand testweise ein neues Lazarus-Projekt im aktuellen SVN-Build erstellen, das Widgetset auf GTK2 umschalten und dann folgende units in die uses-liste einfügen:

Code: Alles auswählen

uses gtkdef, gtk2, gdkpixbuf, gtkint, gdk2;

Dann das ganze kompilieren.
Kommen bei euch Meldungen wie

Code: Alles auswählen

/usr/bin/ld: cannot find -lgdk_pixbuf

oder

Code: Alles auswählen

/usr/bin/ld: cannot find -lgtk

oder

Code: Alles auswählen

/usr/lib/lazarus/lcl/units/x86_64-linux/gtk2/gtkint.o: In function `CREATE':
/usr/lib/lazarus/lcl/interfaces/gtk2//../gtk/gtkwidgetset.inc:190: undefined reference to `g_thread_init'

?
Wenn ja und wenn nicht: Welche Linux-Distribution habt ihr und welche version? Dieser Fehler macht mich hier noch ganz verrückt!

So what gives,

ls -l /usr/lib/libgdk_pixbuf*
and
locate libgdk_pixbuf.so

is the second one the problem?

[theo]

Da fehlen einfach Symlinks und libgdk_pixbuf.so.2.0.0. Bei mir funktioniert's und da sieht die Ausgabe so aus: (siehe: /usr/lib/libgdk_pixbuf.so -> libgdk_pixbuf.so.2.0.0)

[Targion]

I created the following symlinks:

Code: Alles auswählen

ln -s -f /usr/lib/libgdk_pixbuf-2.0.so libgdk_pixbuf.so
ln -s -f /usr/lib/libgtk-x11-2.0.so libgtk.so
ln -s -f /usr/lib/libglib-2.0.so libglib.so
ln -s -f /usr/lib/libgdk-x11-2.0.so libgdk.so

now I get

Code: Alles auswählen

/usr/lib/lazarus/lcl/units/x86_64-linux/gtk2/gtkint.o: In function `CREATE':
/usr/lib/lazarus/lcl/interfaces/gtk2//../gtk/gtkwidgetset.inc:190: undefined reference to `g_thread_init'

Disable Thread-Support for GTK2 solves this, but this is no solution.
And why did everything work with an old Lazarus SVN version?

[theo]

Siehst du das nicht etwas zu sportlich mit den links?

Bei mir zeigt
libgdk_pixbuf.so -> libgdk_pixbuf.so.2.0.0
und nicht wie bei dir
libgdk_pixbuf.so -> libgdk_pixbuf-2.0.so

[Targion]

Ich meine die Verknüpfung ist korrekt, auch, wenn das erste nach GTK1 aussieht. Diese Symlinks haben nämlich schon mal funktioniert.
(Ubuntu Jaunty)

[Hitman]

Bezweifel ich - denn gdk-pixbuf-2.0 ist etwas anderes als gdk-pixbuf! Das siehst du auch ganz gut in theo's symlinks, wo beide Libs durchaus unterschiedliche Versionen haben.

[Targion]

Könnte der Compiler gegen eine falsche lib linken? Ich meine, das wäre nicht möglich also müssten die libs identisch sein.

[theo]

Bei mir exportieren die nicht genau das Gleiche afaics.

Nein die sind nicht gleich. gdk_pixbuf ist die Version für GTK1, gdk_pixbuf-2.0 ist die Version für GTK2 - zugegeben, die Versionsnummern sind irreführend, aber NICHT identisch!

(man sieht klar die GTK2 Referenzen)

Bei gdk_pixbuf hingegen sieht man klar nur GTK1 Referenzen:

Hallo!
Ich hatte über diese Sache schon eine längere Diskussion mit Vincent im Bugtracker, dort konnte das Problem allerdings nicht verifiziert werden.
Also, könnte mal jemand testweise ein neues Lazarus-Projekt im aktuellen SVN-Build erstellen, das Widgetset auf GTK2 umschalten und dann folgende units in die uses-liste einfügen:

Code: Alles auswählen

uses gtkdef, gtk2, gdkpixbuf, gtkint, gdk2;

Why don't you use the gtk2 version of pixbuf, if everything else you are using is gtk2:

Code: Alles auswählen

uses gtkdef, gtk2, gdk2pixbuf, gtkint, gdk2;

[Targion]

Okay, this was a complete mistake. I mixed gtk1 and gtk2 libraries within the program, so I think this is resolved.
But I still get

Code: Alles auswählen

Bei dir sind halt alle Symlinks etwas sportlich:
