API development
Development Environment
| Operating system | Compiler |
|---|---|
| Windows | Visual C++ Compiler 19.3X / vcvars: 14.4x |
| Linux | GCC version 10 |
Note: If an API manager/driver was compiled using VS 2019 at least VS 2019 Runtime must
be installed on the target system. Otherwise the error "The system cannot execute
the specified program" is shown.
Development Licenses
Due to the direct dependencies between WinCC OA and Qt, an official QT development license is required to develop custom components - custom managers, Ctrl extensions, drivers, EWOs - using the WinCC OA API.
