Bug#1003813: libghc-lzma-dev: static C library missing as a prerequisite

[Felix Lechner]

Package: libghc-lzma-dev
Severity: normal

Hi,

I am new to Debian's ecosystem for Haskell, so please forgive me if
this filing is perhaps not entirely justified.

When building my new package 'kickoff' [1] using sbuild in a fresh
'unstable' chroot, I received the build error below. It looks to me
like the linker could not find the static LZMA library.

I believe the library is available in the installable 'liblzma-dev'.
(Your package [2] only pulls in the shared version via liblzma5.) Are
consuming sources supposed to depend on the C library separately?

The full build log was attached to this message. Thank you for your guidance!

Kind regards
Felix Lechner
