Below are two tables showing the two problem classes that prevent generation of a build order for cross compilation. This example tries to build all 5577 base source packages on amd64 for armhf in current Debian sid. The source package selection was made according to the problematic packages found by bootstrap.debian.net
A machine parsable version can be retrieved in json format
The source packages in the third column cannot satisfy their (possibly transitive) cross build dependencies because the binary package in the last column. This is mostly because the binary package in the last column is Multi-Arch:no. Some of these packages need to be Multi-Arch:foreign instead. The depchains column shows the dependency chain from the source package to the binary package where applicable.
The output is first grouped by the shared unsatisfied dependency (last column) and then by shared dependency chain (fourth column). The groups are sorted by the number of source packages missing the dependency in the last column. Within each group, the output is sorted by the number of source packages sharing the same dependency chain.
The source packages in the third column cannot satisfy their cross build dependencies because the binary packages in the last column cannot be installed together. Most of these problems can be fixed by using cross compiler translation through abuild dependency on gcc-for-host. This table often contains false entries of conflicts that are only produced by Multi-Arch:same version skews in Debian unstable. The two depchain columns show the paths from the source package in the third column to each of the conflicting binary packages in the last column, respectively. Sometimes, there exist multiple dependency chains exist.
The output is first grouped by the shared conflicting dependency (last column) and then by the shared dependency chains (fourth and fifth column). The groups are sorted by the number of source packages sharing the conflict in the last column. Within each group, the output is sorted by the number of source packages sharing the same dependency chains.
