# LIBUNIXODBC_CHECK_CONFIG ([DEFAULT-ACTION])
|
||
|
|
# ----------------------------------------------------------
|
||
|
|
#
|
||
|
|
# Checks for unixodbc. DEFAULT-ACTION is the string yes or no to
|
||
|
|
# specify whether to default to --with-unixodbc
|
||
|
|
# If not supplied, DEFAULT-ACTION is no.
|
||
|
|
#
|
||
|
|
# This macro #defines HAVE_UNIXODBC if required header files are
|
||
|
|
# found, and sets @UNIXODBC_LDFLAGS@ and @UNIXODBC_CFLAGS@ to the necessary
|
||
|
|
# values.
|
||
|
|
#
|
||
|
|
# Users may override the detected values by doing something like:
|
||
|
|
# UNIXODBC_LDFLAGS="-lunixodbc" UNIXODBC_CFLAGS="-I/usr/myinclude" ./configure
|
||
|
|
#
