How to install on Linux

Download the latest Debian install file(s) for your system from the release section of this repository. If you just want to use a binary that depend on this library there is no need to download the dev version. If you, on the other hand, expect to use the library for development you should download and install both (the dev version holds header files etc).

> sudo apt install ./libvscphelper14_14.0.0-1_amd64.deb
> ./libvscphelper14-dev_14.0.0-1_amd64.deb

If you get

couldn't be accessed by user '_apt'. - pkgAcquire::Run (13: Permission denied)

it is good to know that it is a known apt problem that you safely can ignore. If it feels bad use apt-get to install instead.

or

> sudo dpkg -i ./libvscphelper14_14.0.0-1_amd64.deb
> sudo dpkg -i ./libvscphelper14-dev_14.0.0-1_amd64.deb

How to install on Windows

Install using the windows installation script available in the release section och this repository.

How to build on Linux

The VSCP helper lib is built using a standard cmake build.

  git clone https://github.com/grodansparadis/vscp.git
  git clone https://github.com/grodansparadis/vscp-helper-lib.git

The two projects should be cloned on the same directory level. vscp-helper-lib is the main project and use code from the main VSCP project. If you absolutely want to have them installed on separate places you can use the -DVSCP_PATH="path to vscp" .. option to set the path to the VSCP project.

For the ssl build, additional openssl is necessary:

apt-get install libssl-dev

Now do

  cd vscp-helper-lib
  mkdir build
  cd build
  cmake ..
  make
  make install

How to build on Windows

Install Visual Studio 2022 Buildtools

You can install them from: https://visualstudio.microsoft.com/en/downloads. You find them in the Tools for Visual Studio 2022 on the lower part of the page.

In the Visual Studio Installer, select:

• Tab "Workloads": Buildtools for the universal windows platform

Install the latest cmake

You find it here https://cmake.org/install/

Install git

You find it here https://gitforwindows.org/

Install the vcpkg package manager

Open a Visual Studio 2022 command prompt (x64 Native Tools Command Prompt) window and type:

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

Integrate vcpkg with Visual Studio

  vcpkg integrate install

Install needed vspkg packages

  vcpkg install dlfcn-win32:x64-windows
  vcpkg install expat:x64-windows
  vcpkg install openssl:x64-windows
  vcpkg install pthreads:x64-windows

Clone needed VSCP code

  git clone https://github.com/grodansparadis/vscp.git
  git clone https://github.com/grodansparadis/vscp-helper-lib.git

The two projects should be cloned on the same directory level. vscp-helper-lib is the main project and use code from the main VSCP project. If you absolutely want to have them installed on separate places you can use the -DVSCP_PATH="path to vscp" .. option to set the path to the VSCP project.

Build vscp-helper-lib

  cd vscp-helper-lib
  mkdir build
  cd build
  cmake .. -G "Visual Studio 17 2022" -DVCPKG_TARGET_TRIPLET=x64-windows  -DCMAKE_TOOLCHAIN_FILE=E:\vcpkg\scripts\buildsystems\vcpkg.cmake

The path to the vspkg build script (E:\vcpkg\scripts\buildsystems..) is obviously different in your case.

Now use

  cmake --build . --config Release

to build the dynamic library (Relase or Debug). An alternative is to use

  msbuild libvscphelper.sln /p:Configuration=Release

You can also open the vscphelper.sln in Visual Studio 2019 and work with it there.

Now you can use

cpack

to build an installation package for windows.
