[Mono-devel-list] MONO: Missing libs or bug!?

[Tiago Lima]

Hi,

I've noticed this problem with mono (the file BitmapTest is in attachement):
In Suse8.2...

    # mcs --version
    Mono C# compiler version 0.27.0.0

    # mono --version
    Mono JIT compiler version 0.28, (C) 2002, 2003 Ximian, Inc.

    # mcs -r:System.Drawing BitmapTest.cs
    Compilation succeeded

    # mono BitmapTest.exe
    sysdrawconfig["Implementation"] is null

Am I missing some libs here?

I've installed using YaST the gdk-pixbuf package:
    gdk-pixbuf - A library for fast pixelmanipulation
    Version: 0.18.0-248 Installed: 0.18.0-248 Size: 874.6 kB Media No.: 1
    License: GPL
    Package Group: System/Libraries
    Provides: gdk_pix, libgdk_pixbuf.so.2, libgdk_pixbuf_xlib.so.2,
libgnomecanvaspixbuf.so.1,
    libpixbufloader-bmp.so.1, libpixbufloader-gif.so.1,
libpixbufloader-ico.so.1, libpixbufloader-jpeg.so.1,
    ...

Notice the file <libgdk_pixbuf.so.2> has a different name... So I "ln -s
..." on it...
I try to do it for the remaining package errors but...

    #mono BitmapTest.exe
    sysdrawconfig["Implementation"] is null

    (<unknown>:32760): Gdk-WARNING **: cannot open display: (null)

Did I something wrong ? (like wrong libs ??)
