Make error: processor does not support ARM mode `sbfx r11,r1,#2,#1'

Fail to install on RPi3 (Debian):

See this blog post:

The raspberry pi OS is built with all kinds of strange flags that make detection hard.

Thank you, but this link doesn't work =(

I've pushed 'make' to go forward by 'make -B -i' and there is some other warnings:

Are they related to flag detection?

[MiBatu]

Direct settings hepled to install VOLK =)
Command:

cmake cmake -Dhave_mfpu_neon=0 -DCMAKE_CXX_FLAGS:STRING="-march=armv6 -mfpu=vfp -mfloat-abi=hard" -DCMAKE_C_FLAGS:STRING="-march=armv6 -mfpu=vfp -mfloat-abi=hard" ..

BUT gnuradio still can't find it:

-- Configuring VOLK support...
-- VOLK submodule is not checked out.
-- To check out the VOLK submodule, use:
-- git pull --recurse-submodules=on
-- git submodule update
-- External VOLK disabled.
-- Override with -DENABLE_INTERNAL_VOLK=ON/OFF

CMake Error at CMakeLists.txt:362 (message):
VOLK required but not found.

[n-west]

The message indicates that the volk submodule in gnuradio is not checked out, which indicates you have built VOLK outside of GNU Radio. Have you tried using the cmake flag that the error message suggests, -DENABLE_INTERNAL_VOLK=OFF?

[MiBatu]

Yes, and it was helpful to make GNU Radio without VOLK. But after make install I do not see it correctly placed in X, as it usually happen when I use $ apt-get install gnuradio... so now looking how to run GNU Radio I've installed...

PS: will try to rebuild VOLK inside gnuradio dir. Thank you for your prompt.
