Windows build

Build curl

1. Download curl from https://github.com/curl/curl/releases
2. cd curl_directory\winbuild
3. Read BUILD_WINDOWS.txt for building instructions
4. In VC command prompt execute:

   nmake /f Makefile.vc VC=15 MACHINE=x64 ENABLE_WINSSL=yes MODE=dll
   

   (replace VC and MACHINE with your actual version / platform)
5. If you get the error U1073 or U1077 - execute curl_directory\buildconf.bat first and repeat the nmake command
6. Your curl build directory will be in sub directory builds\

Build NetLicensing C++ client

1. Download the latest release and unpack to NetLicensingClient-cpp (or checkout master to build the latest development version)
2. In the NetLicensingClient-cpp directory create build\ subdirectory
3. Specify curl location using CMAKE_PREFIX_PATH=your_curl_build_directory. curl build directory must contain bin, include, and lib subdirs.
4. In VC command prompt execute:

    cd NetLicensingClient-cpp\build
    cmake .. -G "Visual Studio 15 2017 Win64" -DCMAKE_PREFIX_PATH=your_curl_build_directory
   

   (replace -G argument with your actual version / platform, see cmake documentation)
5. Open solution created in NetLicensingClient-cpp\build directory in Visual Studio and build the library and demo client.

Linux build

Build NetLincesing-cpp

1. Download the latest release and unpack to NetLicensingClient-cpp (or checkout master to build the latest development version)
2. Install libcurl (for development, including C headers and libraries). E.g. in Ubuntu: sudo apt-get install libcurl4-openssl-dev
3. Install boost: sudo apt-get install libboost-all-dev
4. In the NetLicensingClient-cpp directory create build/ subdirectory
5. Execute:

    cd NetLicensingClient-cpp/build
    cmake ..
    make
   

Unit tests

Unit tests require Boost Unit Test Framework. To build project with the unit tests activated add cmake option -DBUILD_TESTS=yes. The tests must be executed from tests/ subdirectory on Linux or tests\Debug\ on Windows in order to properly locate the JSON files with test data.

Linux build using docker

TODO: full description

1. Prepare container

   • Image: ubuntu:22.04
   • apt-get update
   • apt-get install cmake g++ libcurl4-openssl-dev libboost-all-dev

2. Map NetLicensingClient-cpp or clone it inside the container

3. Build as described in Linux Build

MacOS build

TODO: full description

1. Prepare environment:

   • Install XCode 10.1+
   • Install homebrew
   • libcurl is provided
   • brew install cmake boost

2. Build as described in Linux Build

Execution environment

libcurl dynamic library should be either installed system-wide or otherwise available for the loading at run-time (typically located in the same directory as your executable)
