I am trying to get cross compilation working, on a 64 bit system that already has i386 enabled:
$ dpkg --print-architecture amd64 $ dpkg --print-foreign-architectures i386 armhf Only jessie repositories are enabled:
$ apt-cache policy libc6:armhf libc6:armhf: Installed: (none) Candidate: 2.19-18+deb8u1 Version table: 2.19-18+deb8u1 0 700 http://http.debian.net/debian/ jessie/main armhf Packages However, I'm getting a strange conflict I cannot decipher ("libc6:armhf : Breaks: libc6 (!= 2.19-18+deb8u1)"), the full apt-get output is found below.
The i386 libc is living peacefully on this system, but the armhf version (and armel for this matter) fails. What do I make of this apt-get error and how do I fix it?
