itk-wasm VS dockcross

This is an example to demonstrate browser-based debugging of C++-generated WebAssembly. For more information, please see the target="_blank" href="https://wasm.itk.org/examples/debugging.html">associated documentation.

Effective debugging results in effective programming; itk-wasm makes effective debugging of WebAssembly possible. In this tutorial, adapted from the itk-wasm documentation, we walk through how to debug a C++ data processing pipeline with the mature, native binary debugging tools that are comfortable for developers. This is a fully featured way to ensure the base correctness of a processing pipeline. Next, we will walk through an interactive debugging experience for WASI WebAssembly. With itk-wasm, we can debug the same source code in either context with an interactive debugger. We also have a convenvient way to pass data from our local filesystem into a WebAssembly (Wasm) processing pipeline.

In this post, adapted from itk-wasm's documentation, we provide a C++ Wasm processing pipeline tutorial that demonstrates how we can write elegant processing pipelines in C++ via itk-wasm's CLI11 command line parser, which provides a rich feature set with a simple and intuitive interface. At the end of this tutorial, you will have built and executed C++ code to Wasm for standalone execution on the command line and in the browser.

While we recommend following along step-by-step, the complete example can also be found in the examples/ directory of the project repository.

We use the add_executable command to build executables with itk-wasm. The Emscripten and WASI toolchains along with itk-wasm build and execution configurations are contained in itk-wasm dockcross Docker images invoked by the itk-wasm command line interface (CLI). Note that the same code can also be built and tested with native operating system toolchains. This is useful for development and debugging.

Docker is great for self-contained build environments, no risk of them breaking each other. Eg. https://github.com/dockcross/dockcross

It is C ++ 11 compatible, I recommend C ++ 17, it is cross-platform (x86, ARMv7, ARMv8, PowerPC, windows, Linux...), Thanks to [dockcross](https://github.com/dockcross/dockcross) .

First of all, I learned basic instructions of AArch64 and how to use cross compile COOL codes into AArch64 assembly codes via dockcross.

It is C ++ 11 compatible, I recommend C ++ 17, with OpenMP (For better multi-core performance), it is cross-platform (x86, ARMv7, ARMv8, PowerPC, windows, Linux...), Thanks to dockcross .

I would not say it easy, but checkout this setup: https://github.com/dockcross/dockcross

I still maintain a single LXC container for each service. So far I'm doing this to run Nginx Proxy Manager and Vaultwarden, as well as a development container where I use Docker to run cross-platform builds with dockcross.

xcross provides Docker images with toolchains for a wide variety of different architectures, C and C++ standard libraries, and both bare-metal and Linux-based systems. A complete list of supported targets can be found here. This differs from dockcross in that it supports numerous more architectures and C runtimes.
