With ncurses[tinfo] it fails to configure while with ncurses[-tinfo] it configures and builds successfully. Reproducible: Always Steps to Reproduce: 1. USE=tinfo emerge -1 sys-libs/ncurses 2. emerge -1 dev-haskell/terminfo Actual Results: Fails to configure terminfo claiming that curses library could not be found.

Created attachment 338482 [details, diff] fix build against ncurses[tinfo] Proper fix would probably to use pkg-config, but I don't know enough of autofoo to fix it. Also would need to check if the package builds and links correctly, I have just tested that it configures and builds.
Created attachment 338488 [details, diff] fix build and linking against ncurses[tinfo] Updated the patch, now Darcs builds successfully. Still, the proper fix would be to use pkg-config.
[CCed base-system@] In light of USE=tinfo description looks like failure to export the same symbols is ncurses bug? <flag name='tinfo'> Build curses library (libncurses) sep from the low-level terminfo library (libtinfo) -- usually needed only for binary packages -- but it is binary compatible in either mode </flag>
I don't see how pkg-config will help to save the system from breakage when you rebuild from USE=-tinfo ncurses to USE=tinfo ncurses. It does not change .so's ABI on that action, does it?
With ncurses[-tinfo] all the symbols from libtinfo.so are in libncurses.so, so one needs to link just with -lncurses, but with ncurses[tinfo] the symbols are in two libraries and have to link with -lncurses -ltinfo. pkg-config gives needed values: With ncurses[-tinfo] $ pkg-config --libs ncurses -lncurses With ncurses[tinfo] $ pkg-config --libs ncurses -lncurses -ltinfo This way the right libs are linked. Moreover, pkg-config is supposed to be preferred over AC_CHECK_LIB: http://blog.flameeyes.eu/2008/04/i-consider-ac_check_lib-harmful

One state is more fragile for building/distributing binaries, than another. Anyways, picked upstream patch. > 13 Feb 2013; Sergei Trofimovich <slyfox@gentoo.org> > +files/terminfo-0.3.2.5-tinfo.patch, -terminfo-0.3.1.1.ebuild, > -terminfo-0.3.1.3.ebuild, terminfo-0.3.2.5.ebuild: > Fixed build failure against 'USE=tinfo ncurses' in bug #454216 by Reinis > Danne. Thanks for the report and explanation!
