Vcpkg Library Manager

vcpkg is a C++ library manager for Windows, Linux and MacOS. Consider its prerequisites before going further.

The vcpkg library manager has preconfigured building procedures for OpenSSL and pthreads libraries. They can be easily built and further used as dependencies of SRT library.

Note! vcpkg does not support LibreSSL or MbedTLS libraries.

1. Configure vcpkg

Clone vcpkg using git, and build it.

git clone https://github.com/microsoft/vcpkg.git
cd vcpkg
.\bootstrap-vcpkg.bat

The current working directory will further be referenced as VCPKG_ROOT.

set VCPKG_ROOT=%cd%

2. Build SRT

There are two options to build SRT using vcpkg: by vcpkg itself (Section 2.1) or use vcpkg to build openssl and pthreads, and then build SRT from sources (Section 2.2). The second case makes it possible to build the latest SRT version, while the first case builds only the version included in vcpkg.

2.1. Build with vcpkg

SRT is included in vcpkg (PR 8712). Therefore, Vcpkg can build it with a single command.

vcpkg install libsrt

2.2. Build SRT from sources

2.2.1. Build openssl and pthreads

Then build openssl and pthreads libraries using x64 toolset:

vcpkg install pthreads --triplet x64-windows
vcpkg install openssl --triplet x64-windows

The next step is to integrate vcpkg with the build system, so that CMake can locate openssl and pthreads libraries.

vcpkg integrate install

2.2.2. Build SRT library

Clone the source code of srt.

git clone https://github.com/Haivision/srt.git srt

The current working directory will further be referenced as SRT_ROOT.

set SRT_ROOT=%cd%

From the srt cloned folder SRT_ROOT run cmake to generate build configuration files.

cd %SRT_ROOT%
md _build && cd _build
cmake ../ -G "Visual Studio 16 2019" -A x64
          -DCMAKE_TOOLCHAIN_FILE=%VCPKG_ROOT%\scripts\buildsystems\vcpkg.cmake

where SRT_ROOT and VCPKG_ROOT were defined above.

To build the project go to %SRT_ROOT%\_build and run:

cmake --build ./ --config Release

Alternatively Visual Studio IDE can be used by opening the generated solution file SRT.sln in the _build folder.
