8.5.2 and IKVM.Tools.Importer error "fatal error IKVMC5025: Unable to load runtime assembly"

[marcomoret]

I try to convert a .jar into dll file but, from 8.5.2 I get this discussion subject error
I run this simple command ./ikvmc.exe -out:output.dll input.jar into this folder
...\ikvm.msbuild.tools.runtime.win7-x64\8.5.2\ikvmc\net461\win7-x64
where is the problem? With old version of ikvm all run correctly

ikvmc requires that you use -reference to point to every DLL from the target framework that you are compiling the assembly for, as well as the -runtime argument to point to the IKVM.Runtime.dll assembly that you want the resulting assembly to bind to.

These options exist because there is no longer a single .NET Framework for which you might be generating an assembly. There are like 200 different versions of Core, at various version levels, that you might use the same tool to operate against, and multiple versions of IKVM.Runtime you might want to cross target (using the .NET Core 3 version of the tool to target a .NET 5 version of the assembly, etc).

The required arguments have thus become very complicated.

Which is why IkvmReference and MavenReference now exist. These let you directly add a Java library from Maven, or from a raw .JAR file, to your .NET project, as part of it's build, where the build scripts assemble the appropriate options based on what your own library targets.

Can you write me a sample step by step procedure to create my output.dll file?

[wasabii]

I would consult the README for the ideal steps.

[marcomoret]

thanks

Maybe I understand the problem but not the solution.
When I use ikmvc.exe 8.5.2 to trasform a jar file into dll I find this error:

IKVM.ByteCode need System.Runtime.CompilerServices.Unsafe, Version=6.0.0.0

but if I put the correct System.Runtime.CompilerServices.Unsafe.dll, I find this other error

System.Memory need System.Runtime.CompilerServices.Unsafe, Version=4.0.4.1

Maybe the problem is System.Memory.dll included into ikvm 8.5.2, that dll need and old System.Runtime.CompilerServices.Unsafe.dll version

[wasabii]

Well I feel like I already answered that.

[marcomoret]

the readme say this:

Statically: By compiling a Java application into a .NET assembly using , or ikvmc....

but I don't find the ikvmc sample use into readme, can you help me?
thanks

[wasabii]

There are no samples. I explained the likely issue in the very first answer I gave you. The two options before ikvmc are strongly recommended.

Please try them first.

I have an old .Net project that include my file.dll created by ikvmc.exe statically
Up to ikvmc.exe 8.4.2 version I used "ikvmc.exe -out:file.dll file.jar" and all worked correctly
from 8.5.2 the dll that ikvmc.exe search have a problem on System.Runtime.CompilerServices.Unsafe.dll because System.Memory.dll 4.0 need System.Runtime.CompilerServices.Unsafe.dll 4.0 but IKVM.ByteCode 8.5.2.0 need System.Runtime.CompilerServices.Unsafe.dll 6.0.
If I try to use a more new System.Memory.dll I find che ikvmc.exe use IKVM.Tools.Importer.dll 8.5.2 that search System.Memory.dll 4.0

I have an old .Net project that include my file.dll created by ikvmc.exe statically

So fix it.

Hi, I try to use the first approach: IkvmReference
but no dll is created after rebuild VS project
I make simple steps:
create project
install IKVM package
add .jar like project reference
add PackageReference and IkvmReference in project file

[marcomoret]

Now I retry SDK with Ikvm reference. I need to install NuGet package in PackageReference mode or Packages.config mode?

[marcomoret]

I get this error now
...\obj\Debug\net6.0<projectname>.AssemblyInfo.cs' not found.'....

[wasabii]

There is no such thing as a package.config mode when using SDK style projects, which you have to use, as I mentioned a month ago.

Are you using SDK-style projects?

[marcomoret]

now yes. I re-try your suggest steps

[marcomoret]

Now I use SDK-style project and PackageReference to install NuGet IKVM package but the problem is the same: ...\obj\Debug\net6.0.AssemblyInfo.cs' not found.'....
Have you some idea to solve it?
