#89: Sharing of object files between executable builds? ---------------------------------+------------------------------------------ Reporter: bjorn(a)bringert.net | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Cabal-1.8 Component: Cabal library | Version: Severity: minor | Resolution: Keywords: | Difficulty: normal Ghcversion: 6.4.2 | Platform: Linux ---------------------------------+------------------------------------------ Comment (by EricKow): As requested by Duncan, I am noting here why this would be useful for the darcs team: we plan to introduce some sort of libcabal at some point, but without sharing object files we would have to recompile either 130+ modules between libdarcs and darcs. To make matters worse, we also have a make_authors and a preproc program which compiles our AUTHORS file and helps build our user manual respectively. We also used to have a make_changelog program. All of these programs re-use a good chunk of what will soon be libdarcs, so without proper sharing of object files, we would be compiling the same files at least 4 times.

Maybe a cabal flag to turn it on for developers? Or maybe file a > wishlist with cabal to have all the warnings appear again at the end of the > compile run? What would you think, Duncan? People sometimes suggest we should have a feature flag we turn on in devel vs release builds for this kind of thing. One nice thing about the way cabal files currently work is that they encode the decisions that developers need to make on behalf of users, but that then user choices are not in the .cabal file but expressed as configure flags (eg to build with profiling, optimisation or docs). Sometimes of course devs need to various combinations of configure flags for their standard development / debugging / testing builds. One way to do that would not involve encoding all that stuff into the .cabal file would be to have optional build configuration files that the developers use. Basically it'd consist of a set of flags that are passed to cabal configure (though with a more config-file-like syntax). Indeed it'd be pretty similar to the ~/.cabal/config file but it would apply just to that package. That would let you add things to the local config file like: ghc-options: -Werror and there's no reason why such files could not be put into a darcs repo. Though obviously they cannot be included into a distribution tarball (cabal sdist and cabal/hackage check would enforce that). Sound reasonable? Should we file a cabal-install feature request?

"latest" links to API docs on HackageDB?
by Malcolm Wallace 11 Nov '08

11 Nov '08

HackageDB documentation links for the "latest" version of packages appears to be missing. For instance, the haskell.org wiki at http://www.haskell.org/haskellwiki/Opengl points to Haddock'ed API documentation at http://hackage.haskell.org/packages/archive/OpenGL/latest/doc/html/ http://hackage.haskell.org/packages/archive/GLUT/latest/doc/html/ but there is nothing there (404 not found). Searching around, I eventually discovered documentation for specific versions (2.1 and 2.2.1.1), but having a simple "latest" link that always works would be very useful. Regards, Malcolm

Haskell source packages in Hackage

Hi guys, I am having an hard time installing the haskell-src and haskell-src-exts packages, since both seem to have problems with happy. I have installed happy 1.18.2 successfully, but it does not seem to be visible (although the happy executable is in my path). I get the errors: $ cabal install haskell-src Resolving dependencies... 'haskell-src-1.0.1.3' is cached. Configuring haskell-src-1.0.1.3... Preprocessing library haskell-src-1.0.1.3... cabal: The program happy is required but it could not be found cabal: Error: some packages failed to install: haskell-src-1.0.1.3 failed during the building phase. The exception was: exit: ExitFailure 1 $ cabal install haskell-src-exts Resolving dependencies... 'haskell-src-exts-0.3.9' is cached. Configuring haskell-src-exts-0.3.9... cabal: happy version >=1.17 is required but it could not be found. cabal: Error: some packages failed to install: haskell-src-exts-0.3.9 failed during the configure step. The exception was: exit: ExitFailure 1 Is this some kind of bug in cabal, or in the packages themselves? Thanks, hugo -- www.di.uminho.pt/~hpacheco

bootstrapping cabal-install on windows..
by Claus Reinke 11 Nov '08

11 Nov '08

using the cabal.exe linked from http://ghcmutterings.wordpress.com/2008/11/10/bootstrapping-cabal-install/ I set out to try cabal update; cabal install cabal-install. Since the executable doesn't seem to be linked from anywhere else, I assume you are still testing this? The first thing I noticed is that cabal.exe is somewhat stingy about providing information: there doesn't seem to be a "query" or "info" command and, usually, the only way to get information is to look at the "-v" output of doing something (where is the config file? cabal --help should point to it; what are the dependencies for a given package? we can only ask what cabal --install --dry-run -v is going to do with the dependencies; where do packages get unpacked temporarily, for building?..). Querying should be supported, not just doing. Am I missing something? Having found the config file by looking at the -v output of cabal update.., I tried to enable documentation and to change every path so that cabal would use D: instead of C: (often crowded). That seemed to work, only that I missed that installs seem to be global by default, not user (also, build logs still end up on C:)? (btw, I get lots of warnings about deprecated -ffi) Then I tried cabal install cabal-install (ghc-6.11.20081004, cygwin), and failed. 1. cabal.exe prefers network-2.2.0.0 (installed) over network-2.2.0.1, and building that fails with a Data.Generics issue (wasn't that why the version number was bumped in the first place? and why is it built when it is installed?) 2. trying cabal install network explicitly does install network.2.2.0.1.. 3. cabal install cabal-install still fails, see below build.log attached.

#209: Implement "package()" configurations predicate ----------------------------+----------------------------------------------- Reporter: duncan | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: Cabal library | Version: 1.2.3.0 Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.8.2 Platform: Linux | ----------------------------+----------------------------------------------- We often have to write things like: {{{ flag splitBase description: Choose the new smaller, split-up base package. library if flag(splitBase) build-depends: base >= 3, containers else build-depends: base < 3 }}} Which is verbose and annoying. It would be nicer to say: {{{ library build-depends: base if package(base >= 3) build-depends: containers }}} This is syntactic sugar only. It translates into the existing constructs so no new behaviour is being introduced. It would translate into: {{{ flag _1 library build-depends: base if flag(_1) build-depends: base >= 3 build-depends: containers else build-depends: base < 3 }}} It is described in more detail in this thread: http://www.haskell.org/pipermail/cabal-devel/2007-October/001189.html http://www.haskell.org/pipermail/cabal-devel/2007-November/001336.html -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/209> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

#397: make cabal --cabal-lib-version="" take a dependency or a specific number ---------------------------------+------------------------------------------ Reporter: duncan | Owner: Type: enhancement | Status: new Priority: low | Milestone: Component: cabal-install tool | Version: 1.2.3.0 Severity: minor | Keywords: Difficulty: normal | Ghcversion: 6.8.3 Platform: | ---------------------------------+------------------------------------------ The `--cabal-lib-version=` flag currently takes a specific version number. It could easily be like `--constraint=` or like `cabal install "foo < 2"` and take a dependency or a specific version number. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/397> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects
