# SYNOPSIS
|
|
#
|
|
# AX_EXT_HAVE_LIB(<directories>, <library>, <function>, <extra libraries>)
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# AX_EXT_HAVE_LIB is identical to AC_SEARCH_LIBS with the exception that
|
|
# will add -L<directory> when looking, and use a different variable for
|
|
# each directory.
|
|
#
|
|
# Any required -L<directory> flags are added to LDFLAGS and located
|
|
# libraies are added to LIBS
|
|
#
|
|
# Some libraries are unlinkable without other extra libraries, which can
|
|
# be specified in the 4th argument. The mysql client library needs -lz,
|
|
# for example.
|
|
#
|
|
# Example:
|
|
#
|
|
# AX_EXT_HAVE_LIB(/lib /usr/lib /usr/local/lib /usr/lib/mysql /usr/local/mysql/lib, mysqlclient, mysql_init, [-lz])
|
|
#
|
|
# which finds the mysql client library if succeds system when it tries
|
|
# with -L/usr/lib/mysql then it adds -lmysqlclient to LIBS and
|
|
# -L/usr/lib/mysql to LDFLAGS.
|
|
#
|
|
# The test itself is based on the autoconf 2.53 version of AC_SEARCH_LIBS.
