Building OpenHantek from source
You need the following software, to build OpenHantek from source:
- CMake 3.5+
- Qt 5.4+
- FFTW 3+ (prebuild files will be downloaded on windows)
- libusb 1.x (prebuild files will be used on windows)
- A compiler that supports C++11
We have build instructions available for Linux, Apple MacOSX and Microsoft Windows.
Run OpenHantek
You need an OpenGL 3.2+ or OpenGL ES 2.0+ capable graphics hardware for OpenHantek.
OpenGL is prefered, if available. Overwrite this behaviour by starting OpenHantek
from the command line like this: OpenHantek --useGLES.
USB access for the device is required:
- As seen on the Microsoft Windows build instructions page, you need a special driver for Windows systems.
- On Linux, you need to copy the file
firmware/60-hantek.rulesto/lib/udev/rules.d/and replug your device.

Contribute
We welcome any reported Github Issue if you have a problem with this software. Send us a pull request for enhancements and fixes. Some random notes:
- Read how to properly contribute to open source projects on GitHub.
- Create a separate branch other than master for your changes. It is not possible to directly commit to master on this repository.
- Write good commit messages.
- Use the same coding style and spacing
(install clang-format. Use make target:
make formator execute directly from the openhantek directory:clang-format -style=file src/*). - Open a pull request with a clear title and description.
- Read Add a new device if you want to know how to add a device.
- We recommend QtCreator as IDE on all platforms. It comes with CMake support, a decent compiler, and Qt out of the box.
