# SYNOPSIS
|
|
#
|
|
# AX_APPEND_LINK_FLAGS([FLAG1 FLAG2 ...], [FLAGS-VARIABLE], [EXTRA-FLAGS], [INPUT])
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# For every FLAG1, FLAG2 it is checked whether the linker works with the
|
|
# flag. If it does, the flag is added FLAGS-VARIABLE
|
|
#
|
|
# If FLAGS-VARIABLE is not specified, the linker's flags (LDFLAGS) is
|
|
# used. During the check the flag is always added to the linker's flags.
|
|
#
|
|
# If EXTRA-FLAGS is defined, it is added to the linker's default flags
|
|
# when the check is done. The check is thus made with the flags: "LDFLAGS
|
|
# EXTRA-FLAGS FLAG". This can for example be used to force the linker to
|
|
# issue an error when a bad flag is given.
|
|
#
|
|
# INPUT gives an alternative input source to AC_COMPILE_IFELSE.
|
|
#
|
|
# NOTE: This macro depends on the AX_APPEND_FLAG and AX_CHECK_LINK_FLAG.
|
|
# Please keep this macro in sync with AX_APPEND_COMPILE_FLAGS.
