Hi Rey + Robert, I've just also been hit by a bug that was already filed some 5 months ago in the osmocom.org bug tracker: http://osmocom.org/issues/3512 It seems that the bladerf support to gr-osmosdr added in 2018 unconditionally accepts any libbladerf version installed and subseequently enables the support for it, only then to fails to compile as it actually appears to require a minimum version of 2.0.0 for which it doesn't check during the cmake step. I don't know much about Cmake and hence it would be great if you as the authors of the related code could find a minute to ensure that gr-osmosdr will simply not try to build bladerf support if the version of libbladerf is too old. I'm aware that I can of course manually disable bladerf support, but that's more a work-around than a proper solution, IMHO. Thanks in advance!
