Hi all, [Re-sent as I think something went wrong the first time, the mail did not appear in the archive.]
I'm working on a new feature for QCanBus to enumerate all available CAN interfaces and query more information about them [0].
As it turns out, the Linux SocketCAN API allows a lot, but exactly this task is a bit complicated, see mailing list thread [1].
In this thread, Kurt Van Dijck proposed his network interface enumeration library [2], licensed under LGPL V3, which perfectly allows to query all SocketCAN devices. QNetworkInterface::allInterfaces() lists them too, but there is for now no way to find out which of them are SocketCAN interfaces.
Now I really don't know how to proceed. I already saw some libs like pcre included in the Qt source tree, but I don't know if this is possible with libenumif too, and which technical and legal requirements are needed.
The same problem may occur with libsocketcan [3] which provides more low-level function like CAN controller hardware reset. But this library is more widely used and really stable, so dynamically loading with QLibrary may be enough here.
Thanks for any pointers!
