The reason the ports system can't detect that you've already got mysql-cl=
ient
software installed is because you haven't got libmysqlclient.so in your l=
oader
cache. Try this command -- you should get similar output:
lack-of-gravitas:~:% ldconfig -r | grep mysqlclient
441:-lmysqlclient_r.14 =3D> /usr/local/lib/mysql/libmysqlclient_r=
=2Eso.14
442:-lmysqlclient.14 =3D> /usr/local/lib/mysql/libmysqlclient.so.=
14
ldconfig(8) needs to be told to scan /usr/local/lib/mysql for shared libr=
aries,
as that's not one of the default directories. This is generally handled =
through
the ldconfig_compat port which installs precisely one file:
sisyphus:~:% pkg_info -L ldconfig_compat-1.0_7=20
Information for ldconfig_compat-1.0_7:
Files:
//etc/rc.d/ldconfig_compat
although you can also add /usr/local/lib/mysql to the set of stuff scanne=
d by
ldconfig by modifying variables in /etc/rc.conf (but that's the old and
unfashionable way of doing this...). Re-installing that port and running=
/etc/rc.d/ldconfig_compat start
should sort out the problem you're seeing.=20
Note that mergemaster(1) will ask you to delete that file because it's in=
/etc/rc.d and it's not one of the one installed by the system. You shou=
ld
resist the suggestion to do that, or put up with various MySQL (and certa=
in
other port) related things not working in the way you might expect.
Note too: this is system version number dependant -- recent 6.1-STABLE or=
above
will have the ldconfig_compat script installed in /usr/local/etc/rc.d
Cheers,
Matthew
