Package: dh-haskell
Version: 0.1
Severity: important
Tags: patch
I'm packaging a utility written in Haskell that doesn't provide any libraries,
just executables. The build fails with:
> debian/haskellbuild.setup register --builddir=dist-ghc --gen-pkg-config
> Package contains no library to register: blah-1.0.0.0...
> dh_auto_install: More than one pkg-config file:
although the problem is actually that there are *no* pkg-config files.
I was able to work around it with:
override_dh_auto_install:
touch foo.conf
dh_auto_install $(DH_INTERNAL_OPTIONS)
This is ugly, of course, and I'd prefer not to have to do it.
I've looked at the code in install_pkg_config(), and it seems that if there
are no .conf files, the rest of the function should be skipped. However, at
the call site in install(), a conf file name has to be provided, but providing
"/dev/null" seems to work OK. I've tested this change and it seems to work OK,
so I've attached a patch.
