Building chainblocks

Windows

Requirements

• msys2 - https://www.msys2.org/

Instructions

We use gcc and clang a lot, MSVC might work but it's uncharted territory.

Make sure you pull this repository with dependencies git submodule update --init --recursive

1. Open mingw prompt (use mingw64.exe from msys2 folder), run those commands:
   1. pacman -Syu --noconfirm - to do a full update, you might have to reopen the prompt window
   2. pacman -S --needed --noconfirm base-devel mingw-w64-x86_64-toolchain mingw-w64-x86_64-cmake mingw-w64-x86_64-boost mingw-w64-x86_64-ninja mingw-w64-x86_64-clang mingw-w64-x86_64-lld - to install dependencies
2. Add mingw bin to your system environment PATH variable (the windows one, control panel), in otder to run from powershell, vscode, etc
   • Usually C:\msys64\mingw64\bin
3. Open your favorite terminal (could be within visual studio code) pointing to this repo folder
4. Run those commands:

   mkdir build
   cd build
   cmake -G Ninja -DCMAKE_BUILD_TYPE=Debug -DCMAKE_EXPORT_COMPILE_COMMANDS=1 ..
   ninja format; ninja cbl
   

WASM build

Use a mingw64.exe terminal for this.

1. Clone: https://github.com/emscripten-core/emsdk.git

2. Run:

   ./emsdk install latest
   ./emsdk activate latest
   source emsdk_env.sh
   

3. Go back to chainblocks directory and run:

   mkdir build-wasm
   cd build-wasm
   cmake -G Ninja -DCMAKE_BUILD_TYPE=Debug -DCMAKE_TOOLCHAIN_FILE=$EMSDK/upstream/emscripten/cmake/Modules/Platform/Emscripten.cmake ..
   ninja format; ninja cbl
