How do I use Faust2Juce to convert faust.dsp to Jucer Project? - signal-processing

How do I use Faust2Juce to convert faust.dsp to Jucer Project?
Faust creates its code and UI from its own functional language , how do I continuously integrate to JUCE project?

After installing the faust compiler you can use within terminal:
faust2juce -standalone "Example.dsp"
...to get a standalone project.
faust2juce --help
Will give you a more extensive list of commands.
Alternatively use the online compiler, set the architecture to JUCE and then you can download the exec file (a producer project) from there.
Here is a github link to the architecture for more info.

How to include libsignal-protocol-c in my Swift iOS app?

I would like to write something like import SignalProtocol at the top of one of my Swift files and then be able to call the C functions from libsignal-protocol-c.
libsignal-protocol-c's README says: "When integrating into actual applications, you should not need anything beyond CMake. Alternatively, you may integrate the code using a build system of your choice."
I think I'd like to use the Swift Package Manager to integrate libsignal-protocol-c into my Swift iOS app. Is there a way to automatically generate a manifest file, ie, Package.swift, and a module map, ie, a module.modulemap file, from libsignal-protocol-c's CMake files? Or if I need to create these files manually, what should they include? Otherwise, how would I do this with CMake?
How to import and use libsignal-protocol-c in an existing .xcodeProj? is a similar question but for Objective-C projects.
I'm not sure its an answer but I'm going to start using https://github.com/christophhagen/LibSignalProtocolSwift. Seems like a good start.

How to generate Dart code from json structure

The code_build (https://pub.dartlang.org/packages/code_builde) package provides a solution to generate classes and constructors, field and methods for that class.
My ultimate goal is to generate Flutter (https://flutter.io) Widgets based on the json structure given, but I don't know how to do this with the code_build or another package.
So help would be appreciated!
The general way to write something which outputs Dart code is to wrap up the functionality in a Builder and to perform the code generation with build_runner
At a high level you'd write a Builder that:
Has buildExtensions of {".json": [".dart"]}.
Reads in the buildStep.inputId asset and parses the json.
Uses code_builder to build up a String and then write it to the output asset.
Then you'd configure the builder in build.yaml. And either apply it manually to your package, or if you'd like to publish it as a utility it can apply to dependencies.
Your package would have a dev_dependency on build_runner and then you can execute builds with flutter packages run build_runner build.
There are more docs at https://github.com/dart-lang/build/tree/master/docs
You can see an example of a package which does something similar - starts with yaml files and outputs Dart files using code_builder at https://github.com/natebosch/message_builder
There is now an online tool which will generate the Dart classes from a JSON payload if you're only looking to structure your model classes. It won't do it dynamically at runtime, but it's super helpful when you're first building your program.

Linking Header File with Main.Cpp file in Codeblocks

I am trying to use codeblocks to compile the code available here
The thing is every time I try to build and run, I run into the following error:
|/.../head_pose_estimation/opencv2/core/core.hpp|48|fatal error: opencv2/core.hpp: No such file or directory
Does anyone know how I can fix this? Thank you!
You do not have the pre-built (compiled) version of OpenCV, what you currently have are the source files. If you want to do something special with OpenCV (Target/GPU SUpport etc) then you will need to build the framework using an appropriate guide.
If however you simply want to use OpenCV in the most common way then download the pre-built libraries from the OpenCV.org website.
NOTE:
If you are using OpenCV with MinGW compiler, I do not remember if the pre-built is actually pre-built for MinGW. (I dont think they do) In this case you will HAVE to built the libraries. You can find a guide here

Integrate Tesseract OCR engine in iOS?

I am integrated Tessertact Engine in iOS. I used the following tutorial for integration. My code having no error use-tesseract
but i am getting the following error when i run the application
According with your error.
The file is being compiled instead of being copied to output bundle.
Therefore, make sure that in project settings file just copied, not compiled.
Also select that file & make its property as text file, or pure data - in such case it wouldn't be processed by external tool.

Turning XCode command line C++ program into a Cocoa Mac App OSX program

So I have a program that I have been developing for a while (for fun) on XCode written in C++ as a command line tool program. However I just recently had the idea to turn it into a Mac OSX application. The idea would be to use cocoa/objective-c to create the UI and keep the C++ backend. However, I don't know how to add this in to a project that has already been created as a command line program. Would I have to create a brand new project as a cocoa application and copy/paste my existing code over? Or is there a simpler way to achieve what it is I'm looking to do?
A project can contain multiple targets. You can probably do what you want by creating a target that matches the app type you want and then adding existing files as necessary to that target.
