Bug 603632 – dev-lang/ghc[binary] - /usr/lib64/libncursesw.so.5 used by /usr/lib64/ghc-7.10.3/termi_6iVf4EBnOgfIaaOCLRs8jl/libHSterminfo-0.4.0.1-6iVf4EBnOgfIaaOCLRs8jl-ghc7.10.3.so (preserved)

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Chris Henhawke 2016-12-24 09:46:50 UTC]

Upgrading to ncurses-6.0 and uninstalling 5.9 results in the following message:

!!! existing preserved libs: 
>>> package: sys-libs/ncurses-5.9-r101  
 *  - /usr/lib64/libncursesw.so.5  
 *      used by /usr/lib64/ghc-7.10.3/termi_6iVf4EBnOgfIaaOCLRs8jl/libHSterminfo-0.4.0.1-6iVf4EBnOgfIaaOCLRs8jl-ghc7.10.3.so (preserved)
Use emerge @preserved-rebuild to rebuild packages using these libraries  

Running @preserved-rebuild as suggested does not make the message go away, but installing 5.9 alongside 6.0 does.  Uninstalling ghc, removing /usr/lib64/ghc-7.10.3/termi_6iVf4EBnOgfIaaOCLRs8jl/, and reinstalling ghc also results in this message returning.  Doesn't seem related to dev-haskell/terminfo, but rather ghc itself.

Thanks

Which USE flags you are using to build ghc? 'emerge --info ghc' should show it.

dev-lang/ghc-7.10.3::gentoo was built with the following:
USE="binary gmp -doc -ghcbootstrap -ghcmakebinary" ABI_X86="64"
CFLAGS="-O2 -pipe -march=nehalem -march=nehalem -march=nehalem -nopie -fno-stack-protector"
LDFLAGS="-Wl,-O1 -Wl,--as-needed -Wl,-O1 -Wl,--as-needed -nopie"

Ok, USE=binary is special here. Missing dependency should be fixed as:

Thanks for the report!
