This project is part of ASP.NET Core. You can find samples, documentation and getting started instructions for ASP.NET Core at https://github.com/aspnet/AspNetCore.
Use https://github.com/aspnet/AspNetCore/issues for issues with this project.
There are multiple ways to build this library
- Use vcpkg and install the library with
vcpkg install microsoft-signalr
- Build from command line
- Build in Visual Studio (must have the "Desktop Development with C++" workload) by selecting the "Open a local folder" option and selecting the repository root folder
Below are instructions to build on different OS's. You can also use the following options to customize the build:
Command line | Description | Default value |
---|---|---|
-DBUILD_SAMPLES | Build the included sample project | false |
-DBUILD_TESTING | Builds the test project | true |
-DUSE_CPPRESTSDK | Includes the CppRestSDK (default http stack) (requires cpprestsdk to be installed) | false |
-DUSE_MSGPACK | Adds an option to use the MessagePack Hub Protocol (requires msgpack-c to be installed) | false |
-DINCLUDE_JSONCPP | Builds jsoncpp source code as part of the output binary | true |
-DWERROR | Enables warnings as errors | true |
-DWALL | Enables all warnings | true |
-DINJECT_HEADER_AFTER_STDAFX=<header path> |
Adds the provided header to the library compilation in stdafx.cpp, intended to allow "new" and "delete" to be replaced. | <none> |
