Re: Coexistence of Gnuradio 3.7 and 3.8 on one PC

[Harald Fritzsche (DD0VS)]

Hello Barry and all Readers,

unfortunately the compiler stops again with:

[  3%] Building CXX object
lib/CMakeFiles/uhd.dir/convert/convert_with_neon.cpp.o In file included
from /home/pi/gr38/src/uhd/host/lib/convert/convert_with_neon.cpp:10:

error: inlining failed in call to always_inline 'float32x4_t

note: called from here float32x4_t Q0 =
vdupq_n_f32(float(scale_factor));

I will not be able to remove gnuradio 3.7 from the system. If a fresh
one is needed, i may use a fresh sd-card (but requires some extra time
for configuration)
