Description Reinis Danne 2013-02-27 13:20:36 UTC
Trying to build ocaml with ncurses[tinfo] fails at configure. It should use pkg-config to find ncurses.

Reproducible: Always

Steps to Reproduce:
1. USE=tinfo emerge -1 ncurses
2. emerge -1 dev-lang/ocaml

Comment 2 Mark Wright gentoo-dev 2013-09-15 07:42:54 UTC
ocaml-4.01.0 also fails with ncurses use flag on amd64, a workaround is to add this sed in src_prepare():

sed -e 's@"-lcurses"@"-lncurses -ltinfo"@' -e 's@hasgot $libs@hasgot "$libs"@' -i "${S}/configure" || die "sed to fix ncurses failed"
Comment 3 Mark Wright gentoo-dev 2013-09-15 08:07:32 UTC
The 2nd chunk of the previous sed is unnecessary, this works:

sed -e 's@"-lcurses"@"-lncurses -ltinfo"@' -i "${S}/configure" || die "sed to fix ncurses failed"

Comment 5 David Mohr 2013-11-15 23:55:55 UTC
For anyone trying to use this for the 3.12.1 version: the sed needs to go into src_unpack() since src_prepare() isn't used in that ebuild.

Patch (by me) to configure to call:
pkg-config --libs ncurses
to link to the correct libraries, which is -lncurse -ltinfo when ncurses is
built with the tinfo use flag and ocaml is built with the ncurses use flag.

I am applying the same patch to all versions currently in portage:

i hope you plan to submit it upstream first
Comment 8 Jeroen Roovers (RETIRED) gentoo-dev 2014-10-31 10:24:23 UTC
The build system wants a termcap library. With sys-libs/ncurses[-tinfo] that's libncurses but with sys-libs/ncurses[tinfo] it's libtinfo, so the configure check should try to find a termcap library and rely on `pkg-config --libs ncurses'.

Additionally, pkg-config should be called canonically (i.e. inherit toolchain-funcs.eclass and call `tc-export PKG_CONFIG' or a similar solution.

/not/ rely on*
Comment 11 Jeroen Roovers (RETIRED) gentoo-dev 2014-10-31 10:36:45 UTC
Also, why is that patch called *-config-ncurses.patch when it's about tinfo? :)
