botan cannot be cross built from source for a number of reasons. For starters, it build depends on python3-all-dev, which means that it requires a host architecture python interpreter, which cannot be installed. It really needs python for running configure.py, so the development files are entirely unused. python3-all is more than sufficient. Beyond that, it doesn't need all python interpreters, just one. So we can further reduce that to just python3. And then it can be annotated :any to get a build architecture one. At that point, a cross build can be attempted. Given that botan uses an idiosyncratic build system, it is not covered by debhelper. A look into the documentation reveals that one should pass --cpu, --os, --cc-bin and --ar-command. And then it fails running tests despite DEB_BUILD_OPTIONS containing nocheck. Unless bumped to compat level 13 or higher, the override needs to be conditionalized. The attached patch fixes all of that. Please consider applying it. Helmut
