#
|

# 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.

# SYNOPSIS
|

#
|
||||
# AX_REQUIRE_DEFINED(MACRO)
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# AX_REQUIRE_DEFINED is a simple helper for making sure other macros have
|
||||
# been defined and thus are available for use. This avoids random issues
|
||||
# where a macro isn't expanded. Instead the configure script emits a
|
||||
# non-fatal:
|
||||
#
|
||||
# ./configure: line 1673: AX_CFLAGS_WARN_ALL: command not found
|
||||
#
|
||||
# It's like AC_REQUIRE except it doesn't expand the required macro.
|
||||
#
|
||||
# Here's an example:
|
||||
#
|
||||
# AX_REQUIRE_DEFINED([AX_CHECK_LINK_FLAG])
