Dear Cfarm users, thank you very much for too much responses.

I did not know what is it. My first question contained this link: https://launchpadlibrarian.net/802217984/buildlog_ubuntu-questing-armhf.wp2latex_4.15~ds-1 _BUILDIN > G.txt.gz > Ubuntu-Bug: https://bugs.launchpad.net/ubuntu/+source/wp2latex/+bug/2115809 It is clear that it is meant UBUNTU. -------- I hope that I do not need this platform anymore. First answer from Paul was helpful. #I am not aware of any armhf hardware. #However, at least some of the aarch64 systems have the necessary #cross-compilers to build armhf executables, and can execute them natively. #A trivial demo on cfarm117 appears below. I has been traced defines and it seems that main problem was unalligned access. Ability to access unalligned variables is signelized by this macro: __ARM_FEATURE_UNALIGNED #if !defined(NATIVE_ACCESS) && !defined(HI_ENDIAN) && !defined(__ARM_FEATURE_UNALIGNED) #define NATIVE_ACCESS #endif It is all I need. thanks again Jara > If instead you mean Raspberry Pi, their hardware baseline is ARM v6 > > and someone had to recompile all of Debian as armv6 VFP to make Raspbian, > > all because someone wanted an extra 20% of speed in the cryptography > > code and in long integer divisions by using the count-leading-zeroes > instructions. > > Cheers.
