Below are two tables showing the two problem classes that prevent cross compilation on the dependency level. This example tries to satisfy the crossbuild dependencies of all source packages on amd64 as the build architecture for a dummy architecture generated from amd64 (called armhf here) as the host architecture in current Debian sid.

A machine parsable version can be retrieved in dose yaml format

Bugs are associated with packages on this page if they carry the usertag "cross-satisfiability" of the user "debian-cross@lists.debian.org".

You can get an overview of all bugs tagged like that in the Debian bts

Hover over a package name with your cursor for architecture and version information. Hovering over the arrows in the depchain columns will show the dependency that led from one package in the chain to the next.

The following is a summary of the full "missing" and "conflict" tables below. It only shows the first and last columns of the full tables and only displays the top 10 rows.

missing

The packages in the third column cannot satisfy their (possibly transitive) dependencies because of the unsatisfied dependency in the last column. This is mostly because the binary package providing the dependency in the last column is Multi-Arch:no. Some of these packages need to be Multi-Arch:foreign instead. In some other cases, Build-Depends can be annotated with :native. The depchains column shows the dependency chain(s) from the packages in the third column to the unsatisfied dependency in the last column. The "(*)" placeholder in the depchains column represents any package in the third column. Hovering over the arrows in the depchains column with your cursor will show the dependency that led from one package in the chain to the next.

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 packages missing the dependency in the last column. Within each group, the output is sorted by the number of packages sharing the same dependency chain.

conflict

The packages in the third column cannot satisfy their (possibly transitive) dependencies because the last package(s) in the first depchain have an unsatisfied conflict which is shown in the last column. The second depchain column shows the dependency chain(s) to the package which the last package(s) in the first depchain conflict with. Sometimes, multiple dependency chains sharing the same conflict exist. Hovering over the arrows in the depchains column with your cursor will show the dependency that led from one package in the chain to the next.

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 packages sharing the conflict in the last column. Within each group, the output is sorted by the number of packages sharing the same dependency chains.
