Re: [Machinekit] Usespace component with C++?

[schoone...@gmail.com]

Hi Boris, There is nothing to prevent the use of C++ in userspace components, I do it all the time with Qt. When we were writing the multicore changes and instantiated components, I originally wrote C++ instantiated components, which worked. When we re-visited them recently, I could not remember the build and linkage options I used and was unable to get them built.  Can't remember the exact details. Others tried too with the same result, so maybe something changed in the interim? C++ for a RT component is at best psuedo C++, because several functions have to be declared as static to get the callback references to work and you have to use 'extern "C"' to link to rtapi_app_main()' and 'rtapi_app_exit()'. There would be no compelling reason to use C++ in RT components, but userspace ones allow the full use of GUIs and other useerspace libs and are very useful. regards On 07/02/19 08:51, 'Boris Skegin' via Machinekit wrote: Hallo.
