Good morning, I am trying to backport GCC 4.8 to precise as some daily builds that I maintain [1] fails as the compiler miss the '-std=c++11' flag for g++. So, I tried to backport gcc-4.8; I found out some packages are required, so I got: - eglibc - gcc-4.8 - gcc-defaults - gccgo-4.9 I usually try to build them with pbuilder-dist (pbuilder-dist precise build DSC_FILE), but I found out that each of the above packages requires some binary package generated from another of the source ones. The verbose error plus comments (preceded by '->' or wrapped as '-> COMMENT <-'): - eglibc ... The following packages have unmet dependencies: Depends: linux-libc-dev (>= 3.2.1) but 3.2.0-94.134 is installed. -> can backport, I think Depends: linux-libc-dev (>= 3.4) but 3.2.0-94.134 is installed. -> can backport, I think Depends: libaudit-dev but it is not going to be installed. -> for next errors Depends: libcap-dev but it is not going to be installed. -> for next errors Depends: libselinux-dev which is a virtual package. -> can backport, I think Depends: g++-4.8 which is a virtual package. -> is in the packages to backport above! (gcc-4.8 + gcc-defaults) <- Depends: g++-4.8-multilib which is a virtual package. -> kinda the same of previous line <- Unable to resolve dependencies! Giving up... ... - gcc-4.8 ... Depends: libc6-dev-x32 which is a virtual package. -> is in the packages to backport above! (eglibc) <- Depends: libx32gcc1 which is a virtual package. -> is in the packages to backport above! (gccgo-4.9) <- -> all the packages below can be installed but they won't as previous dependencies are missing... <- Depends: libc6-dbg but it is not going to be installed. Depends: m4 but it is not going to be installed. Depends: libtool but it is not going to be installed. ... - gcc-defaults ... Depends: gcc-4.8-base (>= 4.8.1-6~) which is a virtual package. -> is in the packages to backport above! (gcc-4.8) <- -> all the packages below can be installed but they won't as previous dependencies are missing... <- Depends: lsb-release but it is not going to be installed. Depends: ca-certificates but it is not going to be installed. ... - gccgo-4.9 ... Depends: libc6-dev-x32 which is a virtual package. -> is in the packages to backport above! (eglibc) <- Depends: libx32gcc1 which is a virtual package. -> is in the packages to backport above! (gccgo-4.9), also is the same package! <- -> all the packages below can be installed but they won't as previous dependencies are missing... <- Depends: libc6-dbg but it is not going to be installed. Depends: m4 but it is not going to be installed. Depends: libtool but it is not going to be installed. ... Some ideas to escape this hell?
