Is Cppsharp capable for converting a comprehensive library?

[mahdiye-imanpanah]

Hi guys
I am new to Cppsharp, I just tried to convert some simple C++ projects to be used in C# using Cppsharp.
It worked perfectly for those simple and small projects.
My goal is of course converting comprehensive C++ libraries to C#.
For testing, I tried to convert this source to be used in c# projects using Cppsharp(it is a medium size project).

I built it using cmake and visual studio and it write a test program in c++ to make sure the functionality is ok.
After trying to use the Cppsahrp to convert the code using this code:

using CppSharp;
using CppSharp.AST;
using CppSharp.Generators;
using CppSharp.Parser;
using CppSharp.Passes;

public class SampleLibrary : ILibrary
{
    public void Setup(Driver driver)
    {
        var headers = Directory.GetFiles(@"C:\Desktop\Imath\Installl\include\Imath\");

        // Specify options for the binding generation.
        var options = driver.Options;
        options.GeneratorKind = GeneratorKind.CSharp; // Set the output to C#
        options.GenerateClassTemplates = true;
        options.GeneratorKind = GeneratorKind.CSharp;
        options.GenerateClassTemplates = true;
        options.GenerateDebugOutput = true;

        // Specify the module for the sample library.
        var module = options.AddModule("IMath");

        foreach (var file in headers) 
        {
            module.Headers.Add(file);// Specify the header to bind
        }
        module.IncludeDirs.Add(@"C:\Desktop\Imath\Installl\include\Imath\"); // The include directory of the C++ headers
        module.LibraryDirs.Add(@"C:\Desktop\Imath\Installl\bin\"); 
        module.Libraries.Add("Imath-3_2_d.dll"); // If you have a compiled library
        
    }

    public void SetupPasses(Driver driver)
    {
        // Add passes to rename and convert methods if necessary
        driver.Context.TranslationUnitPasses.RenameDeclsUpperCase(RenameTargets.Any);
        driver.Context.TranslationUnitPasses.AddPass(new FunctionToInstanceMethodPass());
        
    }

    public void Preprocess(Driver driver, ASTContext ctx) { }

    public void Postprocess(Driver driver, ASTContext ctx) { }
}
class Program
{  
    static void Main(string[] args)
    {
        ConsoleDriver.Run(new SampleLibrary()); // Start generating the bindings
    }
}

There were some errors about throw in the source code. I commented them, and finally, the program ran successfully.
After running the program there was an error about DllNotFound I copied the DLL manually to the program bin.
The next problem was about BadImageFormatException I changed the platform and this problem was solved too.
After that I faced this error, System.EntryPointNotFoundException: 'Unable to find an entry point named..., based on information in the user manual I tried to add __declspec(dllexport) to the classes I wanted to use like:
template <class T> class __declspec(dllexport) IMATH_EXPORT_TEMPLATE_TYPE Matrix33.
Now the program knows the Matrix33 but there are some problems:
First, I can not see or access some methods which are available in C++.
Second, those methods that are accessible in the c# program don't run and this error appears:
System.DllNotFoundException: 'Unable to load DLL 'IMath' or one of its dependencies: The specified module could not be found. (0x8007007E)'

I have some questions:
First of all, Is Cppsharp helpful for converting comprehensive C++ libraries? or it is just helpful for simple ones???
Second, I found SWIG that is used for converting C++ codes to other languages, is Cppsharp as powerful as SWIG (just for c# use)?
Third, if the answer to the two previous questions is yes, how can I solve these errors??
