Please see below. I hope that helps. I am also using gcc.
Just in case this is helpful. To build and correctly run my app, I
needed to add the following configuration variables to my
Nothing else is needed because everything is defined with the
Adding CONFIG_NEWLIB_LIBC_FLOAT_PRINTF=y would enable float

Thanks for your help.
Have recently joined project community and am looking for any info
on linking to
existing arm math/dsp library for an embedded arm m4 project. If
this is the wrong
group to address this question to, please advise.
Am using recent (1.1.2) zephyr release and can build and execute c
target hardware with GCC on debian stretch. Would like to use the
arm-published math/dsp library
and have hit a few snags....any suggestions would be appreciated.
I believe this works
on IAR, but am committed to GCC at the moment. First, one of the
arm_math.h, includes <math.h>. Although that file, and other
required files, are in
/usr/include, the zephyr build cannot find them. Is there a way
to add additional include
directories to the build - in particular those specified w/angled
I did a brute force hack to sidestep that issue, but then
encountered problems during the
link phase. Followed the samples example to include external
libraries but linker complained
that the existing arm gcc library and zephyr libraries did not
share the same call formats (CMSIS?). Do I
need to specify that the OS use CMSIS or is that the default?
Appreciate any pointers.
