I am trying to translate a more complex C# program with depdencies. But it fails with failed to resolve assembly. Let me know if you need I can attach the files here. Also is it possible to do partial translation? | am running the command like this: alternative -v -R actions.exe ./output/
This is the output:
Executing alternative command --> translate Loaded Assembly Actions, Version=1.0.5859.41532, Culture=neutral, PublicKeyToken=null Decompiling assembly: Actions, Version=1.0.5859.41532, Culture=neutral, PublicKeyToken=null Output language is C++ Adding /Users/sab/projects/Actions/Actions/bin/Debug to resolver search directories Decompiling assembly: Urho.Desktop, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null Output language is C++ Adding /Users/sab/projects/Actions/Actions/bin/Debug to resolver search directories Decompiling assembly: Urho, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null Output language is C++ Adding /Users/sab/projects/Actions/Actions/bin/Debug to resolver search directories alternative: Failed to resolve assembly: 'System.Runtime, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' at Mono.Cecil.BaseAssemblyResolver.Resolve (Mono.Cecil.AssemblyNameReference name, Mono.Cecil.ReaderParameters parameters) <0x7ee3d8 + 0x0022f> in <filename unknown>:0 at Mono.Cecil.BaseAssemblyResolver.Resolve (Mono.Cecil.AssemblyNameReference name) <0x7ee398 + 0x00038> in <filename unknown>:0 at Mono.Cecil.DefaultAssemblyResolver.Resolve (Mono.Cecil.AssemblyNameReference name) <0x7ee248 + 0x0006b> in <filename unknown>:0 at AlterNative.Program.DecompileAssembly (Mono.Cecil.AssemblyDefinition adef, System.String outputDir, System.String location) <0x7ec788 + 0x00221> in <filename unknown>:0 at AlterNative.Program.DecompileAssembly (Mono.Cecil.AssemblyDefinition adef, System.String outputDir, System.String location) <0x7ec788 + 0x00247> in <filename unknown>:0 at AlterNative.Program.DecompileAssembly (Mono.Cecil.AssemblyDefinition adef, System.String outputDir, System.String location) <0x7ec788 + 0x00247> in <filename unknown>:0 at AlterNative.Program.Run () <0x726d38 + 0x00353> in <filename unknown>:0

In installation instructions, where the INSTALLATION_DIR points?

b2.exe --prefix=<INSTALLATION_DIR> --toolset=msvc-11.0

What I tried:

"C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\MSBuild\Current\Bin\amd64\MSBuild.exe" AlterNative.sln /p:Configuration=net_4_0_Release /p:Platform=x64

But it fails to build, And if you open it up with visual studio and switch all of them to x64 it will again fail to build.
Is it possible to add possibly a release configuration for x64 builds, please?
I am able to test the platform using ProcessExplorer

Hi, I've installed all of the dependencies and cloned the repo, so I go and run install.sh but it ends with this error:
/usr/lib/mono/xbuild/14.0/bin/Microsoft.Common.targets: error : Cannot copy /home/mason/Alter-Native/AlterNative/App.config to /home/mason/Alter-Native/AlterNative.Core.bin/bin/Debug/AlterNative.Core.exe.config, as the source file doesn't exist.
What do I do?
Here's the entire build log:

Try this c# code

class Foo {
    class Bar<T> { }
}

It will pretty much just go off the rails, generating the below code, which among other things, references type Bar which doesn't exist.

class Foo : public virtual Object{
    public:
    class Bar_T{
        private:
        template<typename T>
        class Bar_T_Base : private virtual Object{
            public:
            Bar::Bar_Base(){
            }
        };

        private:
        template<typename T, bool>
        class Bar_T  {
        };
        private:

        //Basic types template type
        template<typename T>
        class Bar_T<T, true> : private Bar_T_Base<T>{
        };
        private:

        //Generic template type
        template<typename T>
        class Bar_T<T, false> : private virtual Bar_T_Base<Object>{
        };
    };
};

I tried a non-generic nested type and it worked OK

Tthe C# Array "Double[]" of double type is treated as pointers to array of pointers to double. For example, a[i] (in C#) would be converted to *(a->GetData(i)) instead of a->GetData(i). After adding "double" as a fundamental type in Lib/src/public/System/support/internal/TypeTraits.h, only some of the cases are handled correctly while others are still not correct.

C# Code Example:
...
// Initialize Gaussian data lists
gauss_h = new Double[fit.num_gauss];
gauss_h_cross = new Double[fit.num_gauss];
gauss_p = new Double[fit.num_gauss];
gauss_p_init = new Double[fit.num_gauss];
for (i = 0; i < fit.num_gauss; i++)
{
vec.error_position[i] = Math.Abs(gauss_p_init[i] - gauss_p[i]) >= extend.peak_diff_cutoff;
}

        // Determine the cross-normalized peak heights
        for (i = 0; i < fit.num_gauss; i++)
        {
            vec.normalized_cross_height[i]  = (CROSS_COEFF * metric_cross * Math.Abs(gauss_h[i])) + (metric * Math.Abs(gauss_h_cross[i]));
            vec.normalized_cross_height[i] /= (CROSS_COEFF * metric_cross) + metric;
        }

...
C++ output:
...
Array* array = new Array((int)(fit->num_gauss));
Array* array2 = new Array((int)(fit->num_gauss));
Array* array3 = new Array((int)(fit->num_gauss));
Array* array4 = new Array((int)(fit->num_gauss));
for (uint num = 0u; num < (uint)(fit->num_gauss); num += 1u) {
vec->error_position->SetData((int)(num), Math::Abs(*(array4->GetData((int)(num))) - *(array3->GetData((int)(num)))) >= extend->peak_diff_cutoff);
}
for (uint num = 0u; num < (uint)(fit->num_gauss); num += 1u) {
vec->normalized_cross_height->SetData((int)(num), ((5.0 * metric_cross) * Math::Abs(array->GetData((int)(num)))) + (metric * Math::Abs(array2->GetData((int)(num)))));
vec->normalized_cross_height->SetData((int)(num), (5.0 * metric_cross) + metric);
}

isnan function is failing in Linux due to latest c++ standard in compiler. I am using Lubuntu 16.04.
The following error message is coming while building 'Lib'.
error: ‘isnan’ was not declared in this scope.
isnan was used in Lib/src/public/System/support/valuetypes.h file at two places(Line no: 60 & 75).
I changed isnan to std::isnan to get rid of this error.
could you please fix this.

This c# will crash AlterNative: class foo { float[] bar = { 1,2,3 }; };
It's easier to see why that might be when you try this:

class foo {
    void baz() {
        float[] bar = { 1, 2, 3 };
    }
};

which results in

void foo::baz(){
    RuntimeHelpers::InitializeArray(new Array<float>(3), fieldof(<PrivateImplementationDetails>{169D9E6B-C4D0-4476-851A-DD23AA0A2F9B}::$$method0x6000001-1)->FieldHandle);
}

For 1 or 2 elements, the c# compiler will emit array stores. For the 3rd element it begins emitting that ugly hacky approach.

Hi,

I've been looking at this project to see how well it works but it seems to fail with almost any of our .NET 2.0 assemblies we tried it with.

After some debugging I narrowed it down to Nullable types. As an example, this simple program will not translate:

public class Hello1
{
public static void Main()
{
bool? foobar;
foobar = true;
System.Console.WriteLine("Hello, World! The nullable is: " + foobar);
}
}

It kicks out an error...
Executing alternative command --> translate

foobar/ does not exists. Created

I get the following error, when trying to compile my output-files:

fatal error: Queue.h: No such file or directory

Do I have to install additional packages/header files to be able to compile? Could only find the Standford C++ library that indeed has this file. I am not sure, but I thought it is a kind of standard C++ header.

Hi, it appears helpful (as i can see many users have Starred it).

How do i transpile Go source into C or C++ source code with it ?
is there a transpiler that can convert Go src into C or C++ src, with (almost all) high level structures used in source, kept fairly same/accurate in output source ?

if this project can keep C# (csharp) source code's high-level structures fairly/accurately same in C++ output source code, then i can use go2cs first.

i have Starred this project too.

EXTRA INFO : BTW , i have mentioned it in a Transpiler List here in SO(StackOverflow) site , would you please UPVOTE it here ( or vote to UNDELETE it ) ? please upvote my Question+Answer, both, if you find it useful or if you think it will be helpful for other users related to this type of transpiler projects . By the way, Transpiler-List can be seen from here or here or find it under my repo(s) here.
( and please downvote user Caleb's answer, as that is incorrect answer . Correct-answer must answer my questions first , My question is about "Transpiler" tools & which "transpiler" tool can keep high-level algorithms/structures intact , Question/article is NOT about language learning, when to transpile & when-not, etc.
In SO site, user Flimzy (and Caleb) doesn't give advice When "C/C++",etc to "Go" conversion related question is posted or when "C/C++" is criticized , But when "Go"-to-"C/C++",etc conversion Question is posted or when Google based products (like "Go"-language) are criticized , then those users, especially Flimzy "Close" the question & downvotes, & gives many un-asked advices, etc, Because those users are Google PUSHERS & google based product (like "Go", Google-Advertisements,etc) PUSHERS . Flimzy edited-out important text from my post criticizing Advertisements . Google Crimes^{1, 2, 3, 4, 5, 6}. Problems in "Go"^{1, 2, 3, 4, 5, 6, 7}. )

EDIT : added links (created new page for Transpiler List).
EDIT : added links ('Go'-problems).

I have question before trying out this project.
I developed game based on OpenTK and it uses AutoGenerated attributes

and it calls OpenGL native functions via p/invoke.
The question is, is this project support with binaries that uses p/invoke feature?

I tried to translate an assembly with the following command:
alternative "D:\Hakan Documents\Visual Studio 2012\Projects\CsharpConsole\CsharpConsole\bin\Debug\CsharpConsole.exe" D:\output

but i got an error:
Length cannot be less than zero.

I traced program and i found where this error occured, Program.cs:313.

So, i changed those lines with mine, and it works fine now.

Take a look at what i wrote:

//string fullPath = "";
//if (Config.Extra[0].Replace('\\', '/').Contains('/'))
//    fullPath = Config.Extra[0].Substring(0, Config.Extra[0].Replace('\\', '/').LastIndexOf("/"));
//else
//    fullPath = Path.Combine(Environment.CurrentDirectory, Config.Extra[0]);

//assemblyLocation = fullPath.Substring(0, fullPath.LastIndexOf('/'));

//Hakan648 - fixed: Length cannot be less than zero.
bool isTargetInADir = Config.Extra[0].Contains('\\');

if (isTargetInADir)
    assemblyLocation = Path.GetDirectoryName(Config.Extra[0]);
else
    assemblyLocation = Path.Combine(Environment.CurrentDirectory, Config.Extra[0]);
