hs-temporary: fails to build on current Macports

[J.Gilbey@…]

I just tried installing pandoc on a fresh macports installation. One of the dependencies which failed to build was hs-temporary; the build log says:

:info:configure Configuring temporary-1.1.2.4...
:info:configure Setup: At least the following dependencies are missing:
:info:configure unix >=2.3 && <2.7
:info:configure Command failed:  cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_devel_hs-temporary/hs-temporary/work/temporary-1.1.2.4" && runhaskell Setup configure --prefix=/opt/local --with-compiler=/opt/local/bin/ghc -v --enable-library-profiling --with-gcc=/usr/bin/clang 
:info:configure Exit code: 1

I tried upgrading to ​http://hackage.haskell.org/package/temporary-1.2.0.3/temporary-1.2.0.3.tar.gz but that also fails:

:info:configure Configuring temporary-1.2.0.3...
:info:configure Setup: At least the following dependencies are missing:
:info:configure exceptions >=0.6
:info:configure Command failed:  cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_devel_hs-temporary/hs-temporary/work/temporary-1.2.0.3" && runhaskell Setup configure --prefix=/opt/local --with-compiler=/opt/local/bin/ghc -v --enable-library-profiling --with-gcc=/usr/bin/clang 
:info:configure Exit code: 1

The exceptions package ​http://hackage.haskell.org/package/exceptions-0.6.1/exceptions-0.6.1.tar.gz has not yet been packaged as a port.

I've just packaged it for my local machine, which seems to have done the trick, but I don't know how to (a) specify in the hs-temporary Portfile that hs-exceptions is needed, or (b) upload the port somewhere useful where others can make use of it. I can attach it to this ticket if that is of use to someone.

The hs-temporary Portfile diff is as follows:

and the hs-exceptions Portfile is attached.

hs-exceptions Portfile

[neverpanic (Clemens Lang)]

Thanks, I'll take a look once I'm back at my Mac.

[J.Gilbey@…]

I guess that query (a) is answered by appending the following to the end of the hs-temporary Portfile:

depends_lib-append port:hs-exceptions

and then rebuilding the index.

[J.Gilbey@…]

Thanks Cal!

I think there may well be a few more of these to come - there are lots of hs-* packages which aren't correctly building since I updated MacPorts for OS X Yosemite. :-(

[neverpanic (Clemens Lang)]

Yes, I'm aware of that. This is mostly related to the recent GHC and Haskell Platform update.

I could have delayed that update until I finished a test build of all Haskell ports, but that would have kept others waiting that are not relying on any Haskell packages other than GHC from MacPorts, so I decided to commit the GHC update and fix the fallout on the fly. As you've noticed, it isn't very hard to fix most of them, but it needs a little time and testing.

Patches such as yours are very helpful in getting the problems fixed quickly, so keep 'em coming -- I'll commit them ASAP.

[joelfrederico@…]

Cal- could you not do that again? Has it really caused a problem keeping others waiting? Because this indirectly broke h5py, which reads/writes HDF files in Python, which is a pretty popular data type AFAIK. Personally, I'm losing a day of work to this.

[neverpanic (Clemens Lang)]

This is a best effort project. I've received multiple requests and inquiries on newer versions of GHC, but as a one man show, I just don't have enough time to test each and every possible haskell package in MacPorts before I upgrade anything. I do welcome helping hands, though, so if you'd like to maintain some of the haskell ports or can provide patches to get stuff fixed that would be awesome.

As a word of warning: If you depend on software in MacPorts for your day-to-day work, please check port outdated for any packages that might break before actually upgrading. Note that you can always go back to older versions by reactivating them, unless you explicitly uninstalled them or ran upgrade with the -u flag.

Bottom line is: We're not Debian, we lack the manpower to pull a large update like this one off in a single step.

[neverpanic (Clemens Lang)]

Turns out I already had the hs-exceptions port locally, but not yet committed, so I did that in r131298.

hs-temporary is updated in r131299, which should fix the build issues.

Please file bugs for any further packages that are broken and you need fixed.
