If you don't want to use prebuilt binary packaged with embit you can build it yourself.

We are using libsecp256k1 fork - secp256k1-zkp.

To build the library run:

make

To clean build directory use:

make clean

In the console type:

sudo apt-get install gcc-mingw-w64-x86-64 g++-mingw-w64-x86-64 wine64

Assuming that Homebrew package manager is installed, in the console type:

brew install mingw-w64
brew install --cask xquartz
brew install --cask wine-stable

Assuming that Chocolatey package manager is installed, in the Powershell type:

choco install mingw make

To build the Windows DLL and the companion library from other platforms run:

make CROSS_DLL=1
