Description Elliott Sales de Andrade 2018-04-04 23:27:27 UTC
With cabal-install 2.0.0, a new scope for executables was added [1]. Private executables are put in a subdirectory of libexec. The default is "$abi/$pkgid" [2].

For example, on x86_64, the result is put in /usr/libexec/x86_64-linux-ghc-8.2.2/pkg_name-pkg_version. The package can own the lower directory, but something should own the ghc one.

The other problem is that I don't know how to generate $abi. I assume 'linux-ghc' is fixed and I can get '8.2.2' from %ghc_version, but I don't know how to get 'x86_64'. I tried to use %{_target}, but that doesn't seem to match what ghc thinks the directory should be on i686 or ppc64le.

Can we have:
a) something to own the libexec subdir (/usr/libexec/x86_64-linux-ghc-8.2.2); and,
b) a macro for this private directory?

Comment 1 Elliott Sales de Andrade 2018-04-04 23:45:34 UTC
See this build for an example [1]. I used '%{_arch}-linux-ghc-%{ghc_version}' instead of '%{_target}-ghc-%{ghc_version}' which fixed it on i686.

However, on ppc64le, ghc thinks the directory should be 'powerpc64le-linux-ghc-8.2.2' while the macros give 'ppc64le-linux-ghc-8.2.2'.

Maybe we should pass `--libexecsubdir='$compiler/$pkgkey'` like is done for `libsubdir`?

Comment 2 Elliott Sales de Andrade 2018-04-05 05:00:30 UTC
So I went with passing `--libexecsubdir='$compiler/$pkgkey'` for cabal-helper, but I'd like to know what we're doing for the future.

Comment 3 Jens Petersen 2018-04-05 07:56:29 UTC
I am not sure which arch/host macro to use, but your approach looks fine to me.

Comment 4 Jens Petersen 2018-04-05 09:36:51 UTC
(You can probably ignore my first cause above.)

I think probably $pkgid would be sufficient for the subdir for now.
Though most dirs in libexec or datadir seem unversioned,
but at least version might avoid any collisions.

I will go with that for now in ghc-rpm-macros.

Can you please test with ghc-rpm-macros-1.8.7-4.fc29 which I built for Rawhide?

Comment 5 Jens Petersen 2018-04-05 10:02:49 UTC
(I didn't add a macro for the libexecdir though but %{_libexecdir}/%{pkgver} should work.)

Comment 6 Jens Petersen 2018-04-05 10:04:59 UTC
In the long term maybe we should change to using the actual base package name
to avoid possible conflicts.

Comment 7 Elliott Sales de Andrade 2018-04-05 23:44:25 UTC
I'm now getting this:

error: Empty %files file /builddir/build/BUILD/cabal-helper-
    Empty %files file /builddir/build/BUILD/cabal-helper-

Comment 8 Jens Petersen 2018-04-06 09:35:44 UTC
Do you have the build.log?

Comment 9 Elliott Sales de Andrade 2018-04-06 09:41:28 UTC
Anything here: https://koji.fedoraproject.org/koji/taskinfo?taskID=26182937
except warp-tls which shouldn't have been in that build.

Comment 10 Jens Petersen 2018-04-07 13:41:32 UTC
Thanks - sorry about that, my bad: this should be fixed by
eclipseo's PR to ghc-rpm-macros:


which I just pushed to Koji

Comment 11 Jens Petersen 2018-04-07 13:51:20 UTC
Looks okay now: https://koji.fedoraproject.org/koji/buildinfo?buildID=1067052
(I built ghc-concurrent-output for you on f29)

Comment 12 Elliott Sales de Andrade 2018-04-10 04:38:46 UTC
Works in what I needed too: https://koji.fedoraproject.org/koji/taskinfo?taskID=26278853

I guess this is also necessary on F28 as well, since that has cabal-install 2?

Comment 13 Jens Petersen 2018-04-10 09:04:23 UTC
Thanks for confirming

Yep, I was meaning to build for f28 - let me do it now.
(I was waiting to add a "fhpkg merge" command but that may take more time.)
