Selected processor does not support 'yield' in ARM mode

[doraemon96]

Explanation

Trying to make hpx for my Raspberry Pi 3b+ (ARMv7l) it throws an error of:
/tmp/ccplVcGc.s:1123 : Error: selected processor does not support 'yield' in ARM mode

Build info

DEVICE => Raspberry Pi 3b+ with ARMv7l
OS >= Running Raspbian 9 (Stretch)
COMPILERS => gcc/g++/c++ version 6.3.0 , cmake version 3.7.2
DEPENDENCIES =>
Hpx downloaded from git (checkout 1.2.1)
Boost libraries (built from source) version 1.69.0
Hwloc libraries (from aptitude repository)
CMAKE COMMAND => (tried lots of combinations) cmake -DCMAKE_BUILD_TYPE=Release -DBOOST_ROOT=/home/pi/boost_1_69_0 -DHPX_WITH_CXX11=ON -DHPX_WITH_MALLOC=jemalloc ../hpx

Already tried

-DCMAKE_CROSSCOMPILING -DCMAKE_CXX_COMPILER=arm-linux-gnueabihf-g++ -DCMAKE_C_COMPILER=arm-linux-gnueabihf-gcc -DHPX_WITH_GENERIC_COROUTINES=ON
(following the cmake toolchain example for crosscompilation)

Extra info

I believe the error could be located in the HPX_SMT_PAUSE definition for ARM directive, and maybe a solution could be found in this boost issue but I'm currently unavailable to fix it.

@diehlpk @biddisco did either of you ever bump into something like this? @doraemon96 thanks for the report and the links. This looks like something we could use.

I had a look at the fiber implementation and we can certainly copy that. I haven't had that problem, but I've not tested the pi3 for some time, so I'd need to have a look when I get home. My x-Compile tool chain is certainly not working without some maintenance as I've not touched it in ages.

I will try to build 1.3.0-rc1 this weekend as maybe this merge: #3591 can solve some problems. Also upgrading cmake to 3.14.4 (because before 3.12 it cannot detect boost_context well). Will keep you updated

Did anything come of this? has anyone tested on Raspberry Pi recently. I have a pi 4 at home and might try a build, but need to setup a toolchain for it (which might be a job for the christmas break).

For future folks viewing - try below. Solved the same error for me on another project:
export CXXFLAG="-march=native -mcpu=native"

[x37v]

CXXFLAG="-march=native -mcpu=native"

shouldn't it be CXXFLAGS plural?
