RE: [users@lists.monobjc.net] An mkbundle with gdiplus.dll

[Anthony Bowker]

Part of the solution seems to be to use adjust the c source code for the
native binary to call either mono_config_parse or mono_config_parse_memory.
Now to sort out my paths and get this working neatly.

Hi everyone,

 

I am having a terrible time building a native binary with mkbundle of my
Application.  My App uses Monoobjc.Cocoa and System.Drawing.  The latter
requires gdiplus.dll.

 

I am using the MonoFramework-2.0_4 and when Mono is installed on the
machine, the machine.config file contains these two dllmap lines to help
apps locate gdiplus.dll:

      <dllmap dll="gdiplus.dll"
target="/Library/Frameworks/Mono.framework/Versions/2.0/lib/libgdiplus.dylib
" />

      <dllmap dll="gdiplus"
target="/Library/Frameworks/Mono.framework/Versions/2.0/lib/libgdiplus.dylib
" />

 

I am using the excellent NAnt.Monobjc.dll mkbundle task to create my native
binary, with the following fragments:

    <mkbundle exe="${build.dir}/MyApp.exe"

        todir="${macbuild.dir}"

        target="MACOSX_10_4"

        universal="true"

        rebuild="true">

      <search-in basedir="${build.dir}"/>

    </mkbundle>

    <mkappl name="MyApp"

        todir="${mac.dir}"

        native="true"

        icon="${build.dir}/Mac/MyApp.icns"

        infoplist="${build.dir}/Mac/Info.plist">

      

      <!-- Copy executable -->

      <copy-in-macos basedir="${macbuild.dir}">

        <include name="MyApp"/>

        <include name="lib*.dylib"/>

      </copy-in-macos>

 

      <!-- Copy other files or folder -->

      <copy-in-resources basedir="${build.dir}/Mac">

        <include name="MyShell.nib/*"/>

      </copy-in-resources>

    </mkappl>

 

When I add the following element, it correctly copies the libgdiplus.dylib
and depenedent files to the MacOS folder of my bundle

    <with-lib
file="/Library/Frameworks/Mono.Framework/Versions/2.0/lib/libgdiplus.dylib"
/>

 

But when I run the app without Mono installed on the machine, I still get
the System.DllNotFoundException: gdiplus.dll

 

So it is obviously missing the dllmap entries and the embedded mono runtime
is not able to resolve gdiplus.dll to libgdiplus.dylib (or in fact
libgdiplus.0.0.0.dylib in this case) to load it from my MacOS directory.

 

I have tried creating both an App.config and Machine.config file and
embedding using the mkbundle task, but Mono still seems unable to either
load the config files, or use the dllmap entries:

<configuration>

  <dllmap dll="gdiplus.dll" target="libgdiplus.0.0.0.dylib"/>

  <dllmap dll="gdiplus" target="libgdiplus.0.0.0.dylib"/>

</configuration>

 

Any help would be very much appreciated!

 

Laurent, I noticed your reply to this list on August 11th (subject: .config
file) in which you mention a possible Mono runtime bug when config files are
embedded with mkbundle.  Is there any update with this?

 

Also, is there any way to programatically set dllmap information, since in
my code before I use System.Drawing?

I would love to say something like MonoRuntime.DllMaps.Add("gdiplus.dll",
"libgdiplus.0.0.0.dylib");

 

Many thanks,

 

Anthony
