BUG: devel/mono doesn't look in /opt/local/lib at runtime

[chris.ridd@…]

The mono-config file included by devel/gtk-sharp maps 'libgtk-win32-2.0.0.dll' to 'libgtk-x11 -2.0.0.dylib', however an application using Gtk fails to load the dylib. This is because it appears to look for the dylib in the paths "", "/usr/local/lib", "/lib", "/usr/lib" and "." (and then across those paths in reverse order, Just In Case.)

If I set DYLD_LIBRARY_PATH to /opt/local/lib, the dylib is located correctly.

% mcs helloworld.cs -L /opt/local/lib/mono/gtk-sharp -r gtk-sharp.dll -r glib-sharp.dll
Compilation succeeded
% unsetenv DYLD_LIBRARY_PATH
% mono helloworld.exe

Unhandled Exception: System.DllNotFoundException: libgtk-win32-2.0-0.dll
in <0x000dc> (wrapper managed-to-native) Gtk.Application:gtk_init (int&,intptr&)
in <0x0004c> Gtk.Application:Init ()
in <0x0001c> Hello:Main ()

% setenv DYLD_LIBRARY_PATH /opt/local/lib
% mono helloworld.exe

(it works)

assigning to maintainer, is this still a issue ? jkh has been poking mono alot lately..

[chris.ridd@…]

Yes, this is still a problem. I just updated and rebuilt devel/mono and x11/gtk-sharp to make sure!

Patch for mono/metadata/loader.c

The appended diff patches (see attachment) the mono sources to avoid this problem. The patch has been been submitted up-stream.

A better fix is to to change the dllmap in the config file installed with a "glue" dll.

[mww@…]

does this problem still persist on version 1.1.7?

(In reply to comment #6)

does this problem still persist on version 1.1.7?

Well yes (sometimes). I'm using 1.1.8 (darwinports) and I did not need to set DYLD_LIBRARY_PATH until I tried to use a method from Mono.Unix and then I got the error:

Unhandled Exception: System.TypeInitializationException: An exception was thrown by the type initializer for Mono.Unix.Syscall ---> System.DllNotFoundException: libMonoPosixHelper.dylib in (wrapper managed-to-native) Mono.Unix.Syscall:_L_ctermid () in <0x00090> Mono.Unix.Syscall:.cctor ()--- End of inner exception stack trace ---

which goes away if I set: export DYLD_LIBRARY_PATH=/opt/local/lib

Note that I've used lots of stuff from gtk# without needing the DYLD var set.

I got the same problem with the current mono version 1.1.10, when using an app called 'autopano-sift' it doesn't find the required libgdaplus (the latter one installed by DarwinPorts for mono). I worked around that by specifying the dll mapping manually in a 'System.Drawing.dll.config'.

[markd@…]

Is this still an issue with mono 1.1.12?

[markd@…]

Mono is up to 1.1.14 now. Reopen this bug if you still have a problem with the port.

[cliff.spradlin@…]

This is occuring to me in MacPorts 1.6 with Mono 1.9. Specifically, mono is not referencing libgdiplus.dylib in /opt/local/lib. /opt/local/etc/mono/config doesn't seem to contain an entry for this.

I get: System.DllNotFoundException: gdiplus.dll

[cliff.spradlin@…]

I tried adding

<dllmap dll="gdiplus.dll" target="/opt/local/lib/libgdiplus.dylib" os="!windows" />

to the mono/config file.

But then when i run the program i get: Unhandled Exception: System.EntryPointNotFoundException: GdipCreateFromContext_macosx

Am I missing something?

[andi@…]

Cc Me!

Replying to cliff.spradlin@…:

I tried adding

<dllmap dll="gdiplus.dll" target="/opt/local/lib/libgdiplus.dylib" os="!windows" />

to the mono/config file.

But then when i run the program i get: Unhandled Exception: System.EntryPointNotFoundException: GdipCreateFromContext_macosx

I did the same changes and get the same result, so this problem still isn't fixed...

[nox@…]

I've fixed this problem in gtk-sharp and gtk-sharp2, I'll soon attach a patch to fix mono.

[nox@…]

Patch against mono 2.0.1 portfile

[nox@…]

Markus, could you look at the patch I've just attached to the ticket? The changes:

• Patch etc/mono/config to fix the DllImport bug.
• Fixed dependencies (mono depends on sqlite3 and cairo, see Mono.Data.Sqlite and Mono.Cairo).
• Kept icu dependency in darwin_9 platform, there is no reason to use the Apple provided icu library.
