• Download Windows build

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 forLinux,Apple MacOSX andMicrosoft Windows.

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 OpenHantekfrom the command line like this:OpenHantek --useGLES.

USB access for the device is required:

• As seen on theMicrosoft Windows build instructions page, you need aspecial driver for Windows systems.
• On Linux, you need to copy the filefirmware/60-hantek.rules to/lib/udev/rules.d/ and replug your device.

Please refer to theSpecifications, Features, Limitations page.

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:

• Readhow to properly contribute to open source projects on GitHub.
• Create a separate branch other thanmaster for your changes. It is not possible to directly commit to master on this repository.
• Writegood commit messages.
• Use the samecoding style and spacing(install clang-format. Use make target:make format or execute directly from the openhantek directory:clang-format -style=file src/*).
• Open apull request with a clear title and description.
• ReadAdd 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.
