These autoconf helper macros come from various sources:

- ax_*.m4: autoconf-archive, version 2017.09.28 (copied)
|

- pkg.m4: pkg-config, version 0.29.2 (run configure, then copy)
|

- gettext.m4, iconv.m4, intlmacosx.m4, nls.m4: gettext 0.19.8

# 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])
