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:
/usr/lib/gcc/arm-linux-gnueabihf/8/include/arm_neon.h:
In member function 'virtual void
__convert_fc32_1_sc16_item32_le_1_PRIORITY_SIMD::operator()(const
input_type&, const output_type&,
size_t)': /usr/lib/gcc/arm-linux-gnueabihf/8/include/arm_neon.h:6740:1:
error: inlining failed in call to always_inline 'float32x4_t
vdupq_n_f32(float32_t)': target specific option mismatch vdupq_n_f32
(float32_t __a)
^~~~~~~~~~~ /home/pi/gr38/src/uhd/host/lib/convert/convert_with_neon.cpp:26:33:
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)
Regards and vy73

going qrt for some family activities :-)
