ghc-mtl currently does not build with mtl-2.1.2 which is currently marked as stable for amd64 in Gentoo itself. See log below, seems like an issue in the package itself (Update the ebuild to a newer version?), not in the ebuild

The changes made between v0.5.2.1 and v0.7.0.2 (current version in repo at time of writing) break some packages that don't set an upper bound on the version of optparse-applicative that they require.

The packages I've found broken after doing a equery d -a and emerge were:

Latest haskell-platform fails to build due to following error: array-0.4 is bundled with ghc-7.4.1, but dev-haskell/parallel-3.1.0.1 requires array >=0.1 && <0.4. The problem seems to be fixed in dev-haskell/parallel-3.2.

It's essential to have this flag enabled if you want to distribute executables that don't weight a ton.
It's already default on Arch and I see no downsides in enabling it for Gentoo.

Configuring vty-4.7.0.4...
setup: At least the following dependencies are missing:
parallel >=2.2 && <3.2

build.log: http://ompldr.org/vYWUydg
emerge -pqv =dev-haskell/vty-4.7.0.4: [ebuild N ] dev-haskell/vty-4.7.0.4 USE="profile -doc -hscolour"
emerge --info =dev-haskell/vty-4.7.0.4: http://ompldr.org/vYWUyeg

In my experience the process for using the gentoo haskell overlay is:

emerge dev-haskell/foo

wait for setup to fail, revealing the packages that foo depends on that need to be installed, and repeat until finally you've managed to install all the (transitive) dependencies.

Aren't package managers supposed to obviate that stuff?

Packages graphalyze, th-lift and gf feature BSD2 and BSD3 licenses, which don't seem to be valid.

``!!! All ebuilds that could satisfy "gf" have been masked.
!!! One of the following masked packages is required to complete your request:

I just tried fresh install cabal-install package and found a problem of circular dependency.

My emerge output can be found here

Seems cabal-1.18.1.1 required dev-haskell/deepseq-1.3.0.1, which required dev-haskell/cabal-1.18.1.1 in turn and the dependency ended up in a circle.

I have a workaround to emerge an earilier version of cabal-install dev-haskell/cabal-install-1.16.0.2 and then update to get the latest version.

GHC 7.0.2, built with the ebuild in this overlay, fails to build Yesod. Turning on FEATURES="nostrip" and rebuilding GHC allows Yesod to build successfully. The error message is the same as the one in this issue:

Current Manifest data misses the information for ghc-7.4.2 making compilation impossible

The problem is in app-text/pandoc/files/pandoc-1.9.4.2-ghc76.patch, since it introduced Data.Default into Setup.hs: GHC 7.4.2 (the version on my machine) does not provide builtin Data.Default, while dev-haskell/data-default is not set as a dependency in the ebuild.

I'm trying to run the latest and greatest with ghc-7.2.0.20110720 and cabal-1.11.1.20110721 and all the dev-haskell packages unmasked. But a few low level packages are dying with this error:

Implicit import declaration:
Ambiguous module name `Prelude':
it was found in multiple packages: base haskell98-2.0.0.0

The packages are:

dev-haskell/glib-0.12.0
dev-haskell/cairo-0.12.0

Some other packages died but mostly due to missing dependencies which had these packages as dependencies.

I think I'm going to re-mask everything I unmasked and downgrade a little bit, but I thought it might be worth reporting anyway.

Hi,
leskah is using ~/.leksah-0.13 as config directory, while the first run wizard is defaulting to ~/.leksah-0.12/packageSources

It makes the system metadata generation fail.

workaround : change to ~/.leksah-0.13/packageSources

Henri

Hi. I recently added the haskell overlay to my home PC, and then upgraded to GHC 7.0.4 from 6.12.(3?), which went pretty well. However, when I try to rebuild dev-vcs/darcs-2.4.4-r1, I die on this error:

Distribution/ShellHarness.hs:106:37:
Not in scope: data constructor `Permissions'

I dug into the code a bit: A see that ShellHarness imports Permissions(..) from System.Directory. However, then I went into the System/Directory.hs in the ghc-7.0.4 code, and it looks to me like the Permissions data type is exported, but the actual constructor is hidden. (Line 58. I'm fairly new to Haskell, so could be wrong...) Presumably then, either the GHC devs did this by accident, or somebody forgot to tell the darc devs that they aren't supposed to use the constructor directly anymore.

It stops with a:
make[1]: *** [utils/ghc-cabal/dist/build/tmp/ghc-cabal] Segmentation fault
make: *** [all] Error 2

See the full build log for details.

after the last happstack-* bumb the versions needed by www-apps/gitit are gone. paludis wants to downgrade to 0.5.0.x:

When I try to build with ghc using the -dynamic flag, the compiler tells me that dyn libraries are not available, and when I look in the package directories under /usr/lib I see *.o and *.a files but not *.so. Why are the shared libraries not built by default, or available to be built via a "dynamic" use flag or something like that?

I've just built HEAD, and, at least on x86, dynamic-by-default is not yet enabled, so this line is extraneous
https://github.com/gentoo-haskell/gentoo-haskell/blob/master/eclass/haskell-cabal.eclass#L342

Test framework 0.8 contains a bug, we need smth to do with it, either add previous version or such.

The current agda-nightly requires unordered containers as dependency

lens-3.0.6 builds and works fine for me on ghc-7.4.1.

A user has reported that the git-annex ebuild here does not include the git-annex-shell symlink to git-annex. This is necessary to use git-annex on a server. Installing git-annex with either "make install" or "cabal install" should create the symlink, or creating it manually in the ebuild is ok (I suppose).

See: http://git-annex.branchable.com/bugs/make_install_doesn__39__t_create_git-annex-shell/

I notice that the overlay has hdbc, hdbc-odbc, hdbc-postresql, and hdbc-sqlite packages, but no hdbc-mysql. Might I suggest you consider adding hdbc-mysql to your tree. Supposedly hdbc-odbc is the "preferred" choice over hdbc-mysql when doing hdbc-based MySQL interaction; however, in my experience hdbc-obdc screws up the Unicode, whereas hdbc-mysql handles it just fine out of the box. I've been working with hdbc-mysql for a month or two now and it has been working great for me.

Thank you for your work.

When building dev-haskell/text-0.11.1.5 with GHC 7.2.0.20110728, the build dies with a cgLookupPanic. Here's the last few paragraphs from the build log:

Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug

Is this really a bug I should report to GHC?

Currently lambdaman reports;

• Invalid entries for files (file changed)
• Files in the Manifest but unknown to git
• Files in FS but not in Manifest

It doesn't report on files that are missing in the FS (still known to git) but exists in the Manifest

Updating binary to 0.7 conflicts with ghc-events and thus with threadscope.

Every time I try to use the interpreter (GHCi, runhaskell, template haskell); I get an error:

/usr/lib64/ghc-7.6.1/base-4.6.0.0/libHSbase-4.6.0.0.o: unknown symbol `stat'

To summarize:

• I only experience this problem on one machine, but not the other
• Both machines use the same architecture (amd64), CHOST (x86_64-pc-linux-gnu), profile (default/linux/amd64/10.0/desktop), gcc ver (4.6.3, only flag difference is USE="graphite" set on the machine that works), ghc ver+flags (7.6.1 with USE="doc"), glibc ver+flags (2.16.0 with default flags), binutils ver+flags (2.23.1 with default flags) and very similar portage options in general.
• I've tried rebuilding glibc, gcc and ghc several times, in various orders
• I experience the problem with (at least) GHC 7.4.2, 7.6.1 and 7.7.2012123
• Using the binary version of 7.4.2 and 7.6.1 works. (I haven't tested a binary of 7.7.x, mainly because none are provided)

The problem seems to be described here: http://haskell.1045720.n5.nabble.com/unable-to-run-ghci-7-4-1-td5683681.html with no solution given

The same problem seems to be described here: https://www.linux.org.ru/forum/development/8001637 with, from what I can decipher, no solution given

Both pages vehemently insist it's a problem with gentoo-haskell's packaging, which is why I'm raising the issue here.

I wasn't able to find a solution in #Gentoo-Haskell, but from the debugging in there, here is some left-over information:

output of readelf -s $(ghc --print-libdir)/base-*/libHSbase* | grep 'stat\>':

Right now hslua pulls in and compiles its own version of lua instead of using library installed from portage; that is utterly unacceptable.

Should ghc-7.4.1 still be hardmasked? The mask comment still says the reason for the mask is that it's the experimental branch, but I think that 7.4.1 is now the stable branch. Or does 7.4.1 still just break a bunch of stuff?

Xmonad doesn't display compile errors without xmessage.
