No that would only be for i586, gmpxx-devel is a virtual provide that is 
arch agnostic.

We always try to use pkgconfig(gmpxx) in preference rather than any 
other in .spec files if they are available, which is why I was so upset 
when you dropped the .pc's from these packages.

I just found my mistake, I had edited the wrong version of the .spec /o\ 
and thanks to your comment I double checked. The gmp* -devels were 
missing from the requires.

gqrx is now building against gnuradio-3.8 (with .pc files) and gr-iqbal 
and gr-osmosdr without.

Thanks again for your help explanations.

Will the 3.8 updates be merged and released soon?
