Name
confLIBSEARCH
Synopsis
The
Build script automatically searches for critical
(to sendmail) libraries and, if it finds any,
automatically enables specific compile-time options. The list of
libraries searched is in the internal
confLIBSEARCH
macro, which defaults to the
following list:
db bind resolv 44bsd
The logic is: if a libdb.a or a
libdb.so library is found in any of the
directories listed with the confLIBSEARCHPATH
macro (confLIBSEARCHPATH), -DNEWDB is
automatically[20] defined for
confENVDEF
(confENVDEF and conf_prog_ENVDEF).
Then the library that is found first (libbind.a,
libbind.so, libresolv.a, or
libresolv.so) is added to the list of libraries
in the confLIBS
macro (confLIBS and conf_prog_LIBS). If lib44bsd is found,
and if libresolv was the first found,
44bsd is also added to the
confLIBS
macro.
In the rare instance that this automatic search misconfigures for
your site or particular build, you can carefully[21] redefine
confLIBSEARCH
. For example, suppose
db has been installed at your site, but it is
broken and you don’t have the time to fix it. You
might do this:
dnl ********** Note, removed db until we fix it, bob ********** define(`confLIBSEARCH', `bind resolv 44bsd')
Note that you must use the dnl
(delete to newline)
directive to form a comment in m4(1).
