[fpc-devel]Gnome gtk freepascal bindings.

[Pascal Pype]

Hello ,

There seem to be some problems about the usage of the free pascal
compiler for freeBSD. An application that once was written for windows
3.1 in turbo pascal needs to be ported to freeBSD and linux. In order
to be able to keep the recoding effort to a minimal level , programming
tools were sought that are compatible to turbo pascal as much as
possible. Free pascal was the answer to that. I choose to use free
pascal 1.0.6. Within free pascal gtk-gnome is highly supported , so
gtk-gnome will serve as toolkit for porting the gui part of the
application. On slackware linux there were no problems about using the
gtk-gnome API at all. On freeBSD however there are several problems
about using the gtk toolkit via the free pascal bindings to gtk.

I use gnome 1-2a on my freeBSD machine and my slackware machine runs
gnome 1.4 upon slackware version 8.0. The version of freeBSD I use is
4.8. The first problem arose when free pascal tried to link the
application. It didn't find the necessary libraries. So I made the
following symlinks:

/usr/local/lib/libgmodule.a -> /usr/local/lib/libgmodule12.a
/usr/local/lib/libglib.a -> /usr/local/lib/libglib12.a
/usr/X11R6/lib/libgdk.a -> /usr/X11R6/lib/libgdk12.a
/usr/X11R6/lib/libgtk.a -> /usr/X11R6/lib/libgtk12.a

Then those libraries were found , but the linker issued a whole bunch
of linker errors:

So one feels the need to add the linker option "-lintl" to resolve
this one. And yes , all linker errors are gone afterwards!

But when one tries to run the application in gnome under the pixmap
theme one receives a true shopping-list of gtk errors and warnings :

gdk_imlib ERROR: gdk has not connected to the display

When one changes the theme to the default theme , then suddenly whoosh
, those pesky gtk warnings are gone ...
And yes , those images are correctly located according to my
"/usr/X11R6/share/themes/Pixmap/gtk/gtkrc" !

If there is no easy solution to that probem , can someone please tell
me how to invoke that single app in such a way that none of the gtk
resource files are taken into account ? So I can continue to use that
app in combination with the pixmap theme that I simply find amazingly
beautiful.

My kind regards , Pype Pascal.
