Hello,

gr-osmosdr currently doesn't build on macOS (probably not with clang in general), because C++17 does not allow the "register storage class specifier".

The fix is quite trivial:

--- a/lib/hackrf/hackrf_sink_c.cc +++ b/lib/hackrf/hackrf_sink_c.cc @@ -299,7 +299,7 @@ void convert_avx(const float* inbuf, int8_t* outbuf,const unsigned int count) #elif USE_SSE2 void convert_sse2(const float* inbuf, int8_t* outbuf,const unsigned int count) { - const register __m128 mulme = _mm_set_ps( 127.0f, 127.0f, 127.0f, 127.0f ); + __m128 mulme = _mm_set_ps( 127.0f, 127.0f, 127.0f, 127.0f ); __m128 itmp1,itmp2,itmp3,itmp4; __m128i otmp1,otmp2,otmp3,otmp4;

Could you please apply that patch and also create a new release? Unfortunately gr-osmosdr was thrown out of the homebrew package earlier this year, because it didn't build. I would like to get it back in, because that would make things on mac a lot easier (and GNURadio tutorials for mac would be correct again and not cause frustration).

I assume the easiest way to get it back in is to have a new official release that builds again correctly.

Best regards Stefan
