ghostscript fails to cross build from source for a number of reasons. The immediate reason is that it configures for the build architecture. It actually attempts to configure twice and the second pass would configure for the host architecture if the first one weren't failing. The first one is completely unnecessary and should be dropped. All that needs to be done here is telling autogen.sh not to call configure. The second issue is that it fails finding zlib. It's a build dependency, so it should be there, no? Almost. ghostscript is quite clever and calls a subconfigure for auxiliary tools with the host architecture set to the build architecture. It actually needs zlib for the build architecture. That's achieved using a :native annotation. It then fails running cups-config. It correctly depends on libcups2-dev, which contains cups-config. Unfortunately, that's a host architecture executable and cannot be run during cross builds. The attached patch solves the first two of these issues. For cups-config there are multiple options. One is fixing cups the other is using pkg-config instead of cups-config if possible. Please consider applying my patch. When doing so, please close this bug even though ghostscript will not be cross buildable. It does hoever make the cups-config issue more visible and easier to talk about. Helmut
