Source: libgpiod Version: 2.1.3-1 Tags: patch User: [email protected] Usertags: ftcbfs
libgpiod fails to cross build from source, because the Python extension is built for the build architecture. There is a tricky environment variable one has to set and when using the pybuild debhelper buildsystem, this is handled automatically, but not when building a Python extension inside autoconf. Thus it needs to be set explicitly. Then it fails for non-default Python versions as only libpython3-dev is included in build dependencies and libpython3-all-dev is missing. The <!cross> annotation on help2man is a lie, because debian/*.install fails when skipping help2man. I have no good answer to help2man unfortunately and that's what makes it continue failing for now. The attached patch fixes the other mentioned issues. Helmut
