guile-cairo fails to cross build from source for two distinct reasons. The first reason is that configure fails running guile-3.0 and gives up. guile-3.0 is M-A:allowed and it occurs twice in the dependency chain. One of them is annotated :any and the one via guile-library is not. As a result, apt picks the host one and that happens to not be runnable. It is guile-library that forces the host one. I believe that its dependency is correct, because guile-library provides shared objects to be loaded into guile-3.0. The question really becomes whether guile-cairo needs to load those libraries. After some digging, I figured that yes it does, but only for running tests. So annotating the dependency <!nocheck> makes the dependency go away for cross builds (as apt can then use the build's guile-3.0) and a nocheck build still exactly reproduces a regular build. What fails next is guile-snarf. I've see than for guile-gnutls already and the cause is that guile-snarf defaults to using the build architecture cpp. Basically whenever using guile-snarf in a build, we must export CPP. I'm attaching a patch addressing both for your convenience. The cross.patch part should be upstreamable. Helmut
