Cabal-1.22 keyed library filepaths
by Jens Petersen 24 Feb '15

24 Feb '15

Hi, I see that with Cabal-1.22, library paths are now of the form: /usr/lib64/ghc-7.10.0.20141222/direc_3m6Ew9I164U5MIkATLCdb8/ libHSdirec_3m6Ew9I164U5MIkATLCdb8-ghc7.10.0.20141222.so etc. Is the 5 character truncation of package names (and no version) necessary? It makes it pretty hard to see at a glance what package a particular directory or file belongs to and seems there is no easy way to work out the package version without referring to the package.conf file/dir. If possible I would prefer a filepath format like: /usr/lib64/ghc-7.10.0.20141222/directory-1.2.1.1_3m6Ew9I164U5MIkATLCdb8/ libHSdirectory-1.2.1.1_3m6Ew9I164U5MIkATLCdb8-ghc7.10.0.20141222.so Would that be feasible/make sense?

making cabal-install into a library?
by Jens Petersen 21 Jan '15

21 Jan '15

Hi, For a while I have been thinking cabal-install should really be a library. Has anyone considered or thought about this? I am wondering how much work it may be? Best wishes, Jens

I have an draft rewrite of bootstrap.sh in haskell. I've tried to improve the maintainability of the code and reliability of running the bootstrap. https://github.com/JakeWheat/cabal/blob/bootstrap-hs/cabal-install/Bootstra… Any feedback is appreciated!

Pre-built binaries should be available with a week or so. Non-exhaustive list of changes: * Support GHC 7.10. * Experimental DWARF debug info output on GHC 7.10 (--enable-debug-info). * Preliminary support for relocatable packages. * Cabal can now be used inside a cabal exec environment. * Fix solver bug where the user's manual flag choice was ignored. * Add GHCJS support. * Improved command line documentation. * Build C sources with -fPIC when GHC is using dynamic libraries. * Preliminary support for package keys (a step on the way to NixOS-like packages). * Add a 'user-config' command to help users manage ~/.cabal/config. * HPC support improved.

I'm pretty sure we just need to update the submodule.

The bootstrap.sh script has to go
by Johan Tibell 02 Jan '15

02 Jan '15

Hi all, I've spent more time on the bootstrap.sh script than anything else, making it emulate cabal flag resolution for the network-uri split and make it deal with the fact that network-uri makes Haddock choke. this release. That feels like a somewhat wasteful activity and I'm tired of maintain a stinking pile of shell script. Unless someone is willing to rewrite it as a Haskell program (that could be run using runhaskell), I vote we dump it and instead encourage users to bootstrap using e.g. the Haskell Platform. -- Johan
