Created attachment 501988 [details] dev-haskell/aeson-1.0.2.1-r1:20171103-134452.log I use the haskle overlay, quickcheck-2.10 is not in Gentoo yet. The ebuild in Gentoo looks like it would behave the same way though. >>> Configuring source in /var/tmp/portage/dev-haskell/aeson-1.0.2.1-r1/work/aeson-1.0.2.1 ... * Using cabal-1.24.2.0. * Prepending /usr/lib64/ghc-8.0.2 to LD_LIBRARY_PATH /usr/bin/ghc -package Cabal-1.24.2.0 --make /var/tmp/portage/dev-haskell/aeson-1.0.2.1-r1/work/aeson-1.0.2.1/Setup.lhs -j4 +RTS -A256M -qb0 -RTS -threaded -dynamic -o setup [1 of 1] Compiling Main ( /var/tmp/portage/dev-haskell/aeson-1.0.2.1-r1/work/aeson-1.0.2.1/Setup.lhs, /var/tmp/portage/dev-haskell/aeson-1.0.2.1-r1/work/aeson-1.0.2.1/Setup.o ) Linking setup ... ./setup configure --ghc --prefix=/usr --with-compiler=/usr/bin/ghc --with-hc-pkg=/usr/bin/ghc-pkg --prefix=/usr --libdir=/usr/lib64 --libsubdir=aeson-1.0.2.1/ghc-8.0.2 --datadir=/usr/share/ --datasubdir=aeson-1.0.2.1/ghc-8.0.2 --enable-tests --ghc-options=-j4 +RTS -A256M -qb0 -RTS --with-ar=gcc-ar --ghc-option=-optc-march=corei7-avx --ghc-option=-optc-pipe --ghc-option=-optc-Og --ghc-option=-optc-g --ghc-option=-optc-gdwarf-4 --ghc-option=-optl-Wl,-O1 --ghc-option=-optl-Wl,--as-needed --ghc-option=-optl-Wl,--hash-style=gnu --disable-executable-stripping --docdir=/usr/share/doc/aeson-1.0.2.1-r1 --verbose --enable-shared --enable-executable-dynamic --sysconfdir=/etc --disable-library-stripping --flag=-developer --flag=-fast Configuring aeson-1.0.2.1... setup: Encountered missing dependencies: QuickCheck >=2.7 && <2.9.3 * ghc-pkg check: 'checking for other broken packages:' * ERROR: dev-haskell/aeson-1.0.2.1-r1::haskell failed (configure phase): * setup configure failed * * Call stack: * ebuild.sh, line 124: Called src_configure * environment, line 2981: Called haskell-cabal_src_configure '--flag=-developer' '--flag=-fast' * environment, line 2081: Called cabal-configure '--flag=-developer' '--flag=-fast' * environment, line 615: Called cabal-show-brokens-and-die 'setup configure failed' * environment, line 713: Called die * The specific snippet of code: * die "$@"
Looking closer at this, it appears that the quickcheck deps in aeson ebuild are lacking a :2 slot operator.
Yeah, hackport needs a fix to pink quickcheck to proper slot. Pushed as: https://github.com/gentoo-haskell/gentoo-haskell/commit/555cbd1bc7464a280774da641be960c2bc368c6e Thanks for the report!
