[07:13] <dholbach> good morning
[21:15] <ia> Hello. Probably this channel not for my question, but I take a chance. Let's say I have a hardware with cpu CPUNAME; If I want to compile C/C++ app for this, then I'm doing something like gcc -march=CPUNAME and it works. But how can I do cross recompilation of some existing deb package [from official ubuntu repo] for such CPUNAME? I guess, that should exist some [auto] tools for this, so when ubuntu dev team preparing packages for arm,x86 and x86-64 from
[21:15] <ia>  the same sources/packages, they probably don't do all those stuff by hands. So I will be very appreciate for pointing me to any relevant direction for solution of this issue. Thanks.
[21:53] <JanC> ia: the Ubuntu dev teams have build daemons running on different hardware
[21:54] <JanC> actually, to some degree you have them too if you have PPA on launchpad
[21:55] <JanC> there is also dpkg-cross
[21:56] <JanC> and pdebuild-cross
[21:58] <JanC> oh, and apt-build of course, if you want to build for a specific CPU within an architecture
[22:01] <JanC> and if you want to set up your own build daemons, have a look at the buildd & rebuildd packages
[22:01] <JanC> oh, and there is mini-buildd too apparently  ☺
[22:07] <JanC> you can also use qemu to run e.g. ARM software on an x86 system
