Needs updates to work with future libiio 1.0

[nmaster2042]

I built last libiio (v1.0) and libad9361 (v0.2).

Now I got errors liking SoapyPlutoSDR

Any issue with these lib versions ?

[zuckschwerdt]

libiio is at 0.25 (there is no 1.0) and the errors look like the lib is not present.

[nmaster2042]

OK, I understand my mistake:

Here is what we can read on the gihub of libiio:

Since August 22th 2023, the "master" branch of libiio contains what will eventually become libiio v1.0. It features a brand new API, which is incompatible with libiio v0.25 and older. Have a look at the wiki for a description of the API changes.

The old v0.x API can still be found in the libiio-v0 branch. Libiio v0.x is now considered legacy, and as such, only important bug fixes will be accepted into this branch.

Old programs compiled against libiio v0.x will still be able to run with libiio v1.0 and newer, as it provides a compatibility layer.

So there is a new V1 but seems to be very early stage for now.

[zuckschwerdt]

Interesting! Let's keep this open as tracker until there is a stable libiio 1.0 to upgrade to.
