Hi, I have an "arch: all" package "python3-pyraf" (source package: "pyraf"), that has a dependency on the package "iraf", but no build dependency on that.
"iraf" exists only on selected architectures due to some required assembler code for each arch and problems with big endian. python3-pyraf is however buildable on all architectures. In the first version of pyraf, I specified: Package: python3-pyraf Architecture: all Depends: iraf and iraf has: Package: iraf Architecture: arm64 armel armhf hurd-i386 linux-amd64 linux-i386 Multi-Arch: foreign >From the description of "Multi-Arch: foreign" I would expect that this allows the dependency resolved by using another architecture. However, piuparts (and the migration excuses) claim a missing dependency on the archs not supported by IRAF. My first thought was to limit the possible archs for python3-pyraf (by explicitly setting the arch list and/or build-depending on iraf), but this would not require the removal of the packages already build. And, in principle the dependency should work across archs (f.e. for x32). But why does it not work with the specification above? Best regards Ole
