Re: OOT Porting from gnuradio v3.7 to v3.8

[Marcus Müller]

Sadly, it's really the issue as shown by your output that your linker can't 
find the itpp
library. Since you've said you've installed it, please check whether it's 
installed where
your toolchain expects it. *how* you've installed it, specifically, might be 
helpful. Was
it also using macports?

Best regards,
Marcus
