Problems packaging ghc-hgettext

[Philip Withnall]

Hi all,

I'm trying to package Bustle[1], and so I first need to package
ghc-hgettext and ghc-setlocale as dependencies.

I can generate a ghc-setlocale package[2] easily enough using cabal-rpm,
but when I try to package ghc-hgettext[3], I get:

+ ./Setup build
        Building hgettext-0.1.30...
        Preprocessing library hgettext-0.1.30...
        [1 of 2] Compiling Distribution.Simple.I18N.GetText
        ( src/Distribution/Simple/I18N/GetText.hs,
        dist/build/Distribution/Simple/I18N/GetText.o )
        [2 of 2] Compiling Text.I18N.GetText ( src/Text/I18N/GetText.hs,

        [2 of 2] Compiling Text.I18N.GetText ( src/Text/I18N/GetText.hs,

        /usr/bin/ld: cannot find -lHSsetlocale-0.0.3-ghc7.4.2
        collect2: error: ld returned 1 exit status

That's with my ghc-setlocale package installed:

$ ls -l /usr/lib64/ghc-7.4.2/setlocale-0.0.3/
        total 500
        -rw-r--r--. 1 root root 152134 Jun 28 10:44
        libHSsetlocale-0.0.3.a
        -rwxr-xr-x. 1 root root  91384 Jun 28 10:44
        libHSsetlocale-0.0.3-ghc7.4.2.so
        -rw-r--r--. 1 root root 259548 Jun 28 10:44
        libHSsetlocale-0.0.3_p.a
        drwxr-xr-x. 1 root root     12 Jun 28 10:47 System

I'm stumped. If I rebuild ghc-hgettext with shared libraries disabled,
it works, but that's not really acceptable. I'm afraid I don't know
enough about the Cabal/rpmbuild/Haskell build and linking process to be
able to diagnose this without spending too much time on it. Hopefully
the answer is obvious to someone else!

Thanks,
Philip

Great!

Maybe you have a user install of setlocale too?

What does "ghc-pkg list setlocale" say?

You can try  "ghc-pkg unregister setlocale" to uninstall the user library.

Ideally Cabal should prefer the system library in this case but I think it doesn't.

Hope that helps, Jens

Reproduced on F19 with:

$ cabal install setlocale
$ cblrpm local setlocale
$ sudo rpm -ivh $(arch)/ghc-setlocale*
$ cblrpm local hgettext
> You can try  "ghc-pkg unregister setlocale" to uninstall the user library.

That fixed it for me.

I think this is fixed with the Cabal in ghc-7.6.3.
So upgrading to F20 should also fix this issue.

I am happy to help review the packages.

Right. I need to set aside a weekend for doing that. This is my work
laptop, so there are very few windows of opportunity to upgrade.

ghc-setlocale: https://bugzilla.redhat.com/show_bug.cgi?id=1115885
ghc-hgettext: https://bugzilla.redhat.com/show_bug.cgi?id=1115894

The Bustle package itself is waiting on two upstream branches to be
merged, and a point release made.

Thanks!
Philip
