Problems packaging ghc-hgettext
by Philip Withnall 03 Jul '14

03 Jul '14

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, dist/build/Text/I18N/GetText.o ) [1 of 2] Compiling Distribution.Simple.I18N.GetText ( src/Distribution/Simple/I18N/GetText.hs, dist/build/Distribution/Simple/I18N/GetText.p_o ) [2 of 2] Compiling Text.I18N.GetText ( src/Text/I18N/GetText.hs, dist/build/Text/I18N/GetText.p_o ) [1 of 2] Compiling Distribution.Simple.I18N.GetText ( src/Distribution/Simple/I18N/GetText.hs, dist/build/Distribution/Simple/I18N/GetText.dyn_o ) [2 of 2] Compiling Text.I18N.GetText ( src/Text/I18N/GetText.hs, dist/build/Text/I18N/GetText.dyn_o ) /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!

news and updates

Hi, It's been quiet here again. I thought I would share a few bits of news and updates. 1) F21 Mass Rebuild Mass Rebuild happened and apart from a hiccup with network which got bumped "accidentally" just before the mass rebuild causing a lot of build failures there were no big surprises. If you maintain packages and haven't already then please check through http://ausil.fedorapeople.org/f21-need-rebuild.html. For network library failures you should be able to run "fedpkg build" now and they should just build. I will try to avoid parking version updates in pkg git in the future - ghc-7.8 preparations have been taking a lot longer than I expected. 2) ghc-7.8 Progress has been a little slow on ghc-7.8 for F21, but assuming 7.8.3 comes out soon I think we can still make it before Alpha/Feature Freeze at the beginning of July. I have written a new build tool(s) [1], finally porting my shell scripts to Haskell for more consistent building and maintainability. (They still need to be parallelized though for more speed up.) Unless the Feature Freeze moves a lot after 2014-07-08 haskell-platform may be get released in time but we already have a good idea of the versions it is expected to ship. 3) Packaging changes for ghc-7.8 With ghc-7.8 we have shared libs and dynamic linking finally on all Linux archs! And I think ghc/ghci support shared only libraries too. (Note also that ghc-7.8 builds static and dyn object files simultaneously to save build time.) So I am considering whether to subpackage static libs and static devel files to save bandwidth and diskspace. Any opinions? At the same time we could also consider bringing back doc subpackages perhaps. One way to keep backward compatibility would be to make -devel a meta package pulling in -static and -doc (we could even have -prof too but I would like to keep the number of subpackages vaguely sane;). I will do some experiments to see how well it might work and report back. Also I have been thinking to drop the generated filelists from the packaging and just list %files lists explicitly. Though since time is short now we might delay this until F22. 4) Package updating for F21 We also have a lot of package updating still to do for F21/ghc-7.8. If you can help with updating your packages in git that would be welcome but please test version changes first with cblrepo using the cblrepo data in haskell-sig.git. [2] I have added some cblrepo output to some of the URM bugs last month and planning to update the bugs and help with more updating soon. 5) I pushed a docker image of Fedora Haskell https://registry.hub.docker.com/u/juhp/fedora-haskell-ghc/ Please give it a try and let me know if you have any feedback. The name is a little long so I might rename it again in the future. At the moment it contains ghc, cabal-install, most of haskell-platform, and some of the most used libraries. I don't remember exactly but I think it is about a ~300MB download once you have the "official" fedora:20 image it is built on top of. 6) Secondary archs Also ghc got bootstrapped recently for ppc64le and aarch64 (arm64). :-) So they should be available for F21 too. Thanks, Jens [1] https://github.com/fedora-haskell/fedora-haskell-tools [2] https://git.fedorahosted.org/cgit/haskell-sig.git/tree/cblrepo/f21
