Hi,
a while ago, Adrian made ghc barely cross buildable. It still builds
something quite different from the regular ghc package, but it crosses
and the crossed thing seems to be able to build a native ghc.
One aspect that didnd't work out at all back then was the dependency on
haskell-devscripts-minimal. We told him, that no, we cannot mark it
Multi-Arch: foreign and we haven't moved forward on that aspect yet.
Therefore Adrian annotatd it "<!cross>". cross builds now need to supply
some haskell-devscripts-minimal to work. What changed since then is that
the apt and dpkg now allow annotating Architecture: all packages with
":native". I think doing so is a better workaround than "<!cross>".
It's a drop in the bucket. Can you apply it anyway?
Helmut

GHC depends on haskell-devscripts-minimal in order to run
'dh_haskell_provides', which lists the libraries GHC provides (it runs
ghc-pkg) and generates the control file.
During cross compilation, we are not able to run the final ghc-pkg
binary and calculate the list of libraries GHC provides. As such, I
believe it doesn't make sense for us to run 'dh_haskell_provides' when
cross compiling GHC. This of course means that the final Debian package
will not have a correct "Provides" field, but as you already mentioned,
the final package of a cross compilation is quite different from the
regular ghc package, so this is acceptable.
I have made the above change in version 9.4.7-1 (i.e., we now don't run
'dh_haskell_provides' when cross compiling) so I will close this bug
report. Feel free to re-open it if there is a better way to handle this.
Best,
