# emerge –ask rasqal raptor

These are the pack­ages that would be merged, in order:

Cal­cu­lat­ing depend­en­cies… done!
[ebuild N ] media-libs/raptor-1.4.18 USE=“unicode –curl –xml“
[ebuild N ] dev-libs/rasqal-0.9.16 USE=“pcre –gmp –test –xml”

…

Then I down­loaded and unpaked the 4store from http://​4store​.org/, then when run­ning configure…

# ./​configure
[OK ] pkg-​config installed
[OK ] rap­tor installed
[OK ] rasqal installed
[OK ] glib2 installed
[OK ] pcre installed
[OK ] read­line installed
[OK ] ncurses installed
[FAIL] no ter­m­cap devel system

I installed sys-​libs/​libtermcap-​compat but did not helped, after a quick chat on #gentoo (irc​.freen​ode​.net), I down­loaded and installed the GNU ter­m­cap from http://​ftp​.gnu​.org/​g​n​u​/​t​e​r​m​c​ap/ (ver­sion 1.3.1 dated 2002!) and all went fine:

# ./​configure
[OK ] pkg-​config installed
[OK ] rap­tor installed
[OK ] rasqal installed
[OK ] glib2 installed
[OK ] pcre installed
[OK ] read­line installed
[OK ] ncurses installed
[OK ] ter­m­cap installed
[OPT ] no avahi, will build without cluster support

# make

The com­pil­a­tion is quite fast, hmmm, I remem­ber 3store was tak­ing longer…but those were dif­fer­ent hard­ware times.

# mkdir /​var/​lib/​4store/​
