I emerged mono-1.0.4 and libgdiplus-1.0.4 and have problems with applications that use System.Drawing. Exception: System.DllNotFoundException: gdiplus.dll This behavior is exactly the same as mentioned in a previous bug: http://bugs.gentoo.org/show_bug.cgi?id=55916 Additional i tried to add the dll to /etc/mono/config: (I pointed it to libgdiplus.so) <configuration> <dllmap dll="cygwin1.dll" target="libc.so.6" /> <dllmap dll="libc" target="libc.so.6" /> <dllmap dll="libintl" target="libc.so.6" /> <dllmap dll="libxslt.dll" target="libxslt.so" /> <dllmap dll="libmySQL.dll" target="libmysqlclient.so" /> <dllmap dll="odbc32.dll" target="libodbc.so" /> <dllmap dll="oci" target="clntsh" /> <dllmap dll="db2cli" target="libdb2_36.so"/> !! ->>>>> <dllmap dll="gdiplus.dll" target="libgdiplus.so"/> </configuration> Reproducible: Always Steps to Reproduce: 1.emerge mono 2.create a simple program that uses system.drawing 3.start it Actual Results: I got the following exception: System.DllNotFoundException: gdiplus.dll Expected Results: Find the dll.

There doesn't need to be a libgdiplus.so.dll, this gets mapped by the runtime appropriately. Usually this actually means there was a problem loading the .so file. Can you try doing: MONO_LOG_LEVEL="debug" mono foo.exe To get a more verbose output and post the relevant section concerning the loading of libgdiplus? Thanks.
The problem seems to be that mono searches a file libgdiplus.so.so in /lib/usr/lib but i couldnt locate libgdiplus.so.so and the path /lib/usr/lib simply doesnt exist Trace: Mono-INFO: DllImport attempting to load: '/usr/lib/libgdiplus.so'.

<snip> Mono-INFO: DllImport error loading library '/usr/lib/libgdiplus.so: undefined symbol: XML_GetCurrentLineNumber'. </snip> ^ that's actually the problem. It's finding the file, but then having a problem resolving one of the symbols. Can you please post the output of "ldd /usr/lib/libgdiplus.so" for me? Also, what version of libtool do you have installed?
My libtool is: 1.5.2-r5 Where is cairo? I thougt mono is using it for gdi+ things.(Wondered about that already when i emerged libgdiplus) ldd /usr/lib/libgdiplus.so linux-gate.so.1 => (0xffffe000) libXrender.so.1 => /usr/X11R6/lib/libXrender.so.1 (0x4011f000) libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x40127000) libXext.so.6 => /usr/X11R6/lib/libXext.so.6 (0x401ee000) libglib-2.0.so.0 => /usr/lib/libglib-2.0.so.0 (0x401fc000) libpng12.so.0 => /usr/lib/libpng12.so.0 (0x4027a000) libz.so.1 => /lib/libz.so.1 (0x402aa000) libm.so.6 => /lib/libm.so.6 (0x402bb000) libpthread.so.0 => /lib/libpthread.so.0 (0x402dd000) libc.so.6 => /lib/libc.so.6 (0x4032e000) libdl.so.2 => /lib/libdl.so.2 (0x4043e000) /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)
I did it the hard way :) I "fixed" it by pasting this to the 1.0.4 ebuild: src_unpack() { unpack ${A} cd ${S} # See bug #55916 einfo "Fixing a libtool problem" rm ltmain.sh aclocal libtoolize --force --copy } This is from the ebuild that fixed bug #55916 Then i created an overlay as described here: http://gentoo-wiki.com/HOWTO_Installing_3rd_Party_Ebuilds ...and reemerged libgdiplus after that my test apps work. I hope this helps anyone.
Looks like the patch from bug# 55916 was added to libgdiplus-1.0-r1, then was removed for libgdiplus-1.0.2 and libgdiplus-1.0.4. As mentioned by Thomas, adding the src_unpack() function fixes the problem. Can this please be added back in to portage tree?
Okay, re-openning so this doesn't get lost. I'll re-add that libtool fix as soon as I get back in front of my dev box.
Ok, i've just commited 1.0.4-r1 which includes the same libtool fix from 1.0-r1. Marking FIXED.
