i am using IKVM to convert a java jar file to a c# dll.

  • 0

i am using IKVM to convert a java jar file to a c# dll.
This jar file has several dependencies, which i referenced all via -r:reference.dll .

Still im getting the following warning and i dont know how to get rid of it:

IKVM.NET Compiler version 7.2.4630.5
Copyright (C) 2002-2012 Jeroen Frijters
http://www.ikvm.net/

warning IKVMC0111: Emitted java.lang.NoClassDefFoundError in "myproject.myclass.setFocus()V"
("org.eclipse.swt.widgets.Control")

The command i am converting the jarfile is:

ikvmc -target:library -debug -out:project.dll -r:org.eclipse.swt.win32.win32.x86_3.5.2.v3557f.dll -r:severalmoreherretofollow project.jar 2> project.log

The class “org.eclipse.swt.widgets.Control” is declared inside the “org.eclipse.swt.win32.win32.x86_3.5.2.v3557f.dll” which had no errors when compiling it with ikvm to a dll.

Thanks in advance

    If you compile more as one jar file then it can be recommended to compile it in one step. See the wiki for more details. This prevent you from circulate dependencies.

    I think you need to use a full qualified file name with the -r option.
