Build

Microsoft Visual Studio 2022 is required to build this library. Simply open the solution file (nip24Library.sln) in the IDE and build the Release version. You can also build it from the Developer Command Prompt for Visual Studio:

git clone https://github.com/nip24pl/nip24-c-client.git
cd nip24-c-client

msbuild nip24Library.sln /t:Rebuild /p:Configuration=Release /p:Platform=x86
msbuild nip24Library.sln /t:Rebuild /p:Configuration=Release /p:Platform=x64

How to use

All required header files are in nip24-c-client/include. Add this path to your project's include directories. Then include nip24.h in your source code — it provides all API definitions.

#include "nip24.h"
