3 dnl @synopsis AX_ENABLE_DEFAULT_PKGCONFIGDIR [(dirvariable [,defsetting])]
5 dnl print a warning message if the $(datadir)/aclocal directory is not
6 dnl in the dirlist searched by the aclocal tool. This macro is useful
7 dnl if some `make install` would target $(datadir)/aclocal to install
8 dnl an autoconf m4 file of your project to be picked up by other
11 dnl default $1 dirvariable = pkgconfigdir
12 dnl default $2 defsetting = ${libdir}/pkgconfig
13 dnl default $3 action = nothing to do
14 dnl default $4 action = warn the user about mismatch
16 dnl In the _WARNING_ variant, the defsetting is not placed in
17 dnl dirvariable nor is it ac_subst'ed in any way. The default
18 dnl fail-action $4 is to send a warning message to the user, and the
19 dnl default accept-action $3 is nothing. It is expected that a Makefile
20 dnl is generated with pkgconfigdir=${libdir}/pkgconfig
22 dnl The _ENABLE_ variant however will set not only the $pkgconfigdir
23 dnl shell var of the script, but it is also AC-SUBST'ed on default -
24 dnl and furthermore a configure option "--enable-default-pkgconfigdir"
25 dnl is provided. Only if that option is set then $2 default is not set
26 dnl to the canonic default in the a $prefix subpath but instead $2
27 dnl default is set to the primary path where `pkg-config` looks for .pc
28 dnl files. The user may also override the default on the command line.
