Hi all, The build went well on all architectures not missing build dependencies. The current implementation injects no compiler optimisation in the state updater steps, so by playing safe the package proved to be rather portable.  https://buildd.debian.org/status/package.php?p=brian I feel like I generated a lot of noise while the issue could be solved with little change actually, I apologize for this but am grateful for your time. Thanks Nilesh for having beaten me at closing the request for removal! :) Michael Crusoe, on 2021-01-30 19:31:42 +0100: > If it is truly for local use, then -march=native is great, but not every > architecture supports "-march=native", so you may need to add work arounds > for archs that don't have that gcc option. > > Here is the result of some reading of the gcc manual page > > -march=native & -mtune=native is valid in gcc for the following Debian > archs: > > arm* > mips* > s390x > i386/amd64/x32 > > but not these > > HPPA > M68k > riscv64 > power*/ppc* (no -march at all, but does have -mcpu=native and -mtune=native) > alpha (no -march at all, but does have -mcpu=native and -mtune=native) > sh4 (no -march at all, no -mcpu either) > sparc64 (no -march at all, but does have -mcpu=native and -mtune=native) > ia64 (no -march, has -mtune but not -mtune=native) Thanks Michael for this precious information, I will use it to bring back some performance to these brian functions, at cost of complexity perhaps, once brian is back to Testing, in the coming week hopefully. Have a nice Sunday everyone, :) -- Étienne Mollier <firstname.lastname@example.org> Fingerprint: 8f91 b227 c7d6 f2b1 948c 8236 793c f67e 8f0d 11da Sent from /dev/pts/2, please excuse my verbosity.
