AX_PKG_CHECK_MODULES(PREFIX, PUBLIC-MODULES, PRIVATE-MODULES, [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND], [PUBLIC-VARIABLE], [PRIVATE-VARIABLE])
A wrapper around PKG_CHECK_MODULES which splits the list of modules into public and private dependencies, and produces two variables listing the dependencies across all invocations of AX_PKG_CHECK_MODULES. These two variables are exposed via AC_SUBST, and should be used in a pkg-config file as the substituted values for Requires and Requires.private.
The PREFIX, PUBLIC-MODULES and PRIVATE-MODULES arguments should be specified as for PKG_CHECK_MODULES, with the concatenation of PUBLIC-MODULES and PRIVATE-MODULES equaling the LIST-OF-MODULES from PKG_CHECK_MODULES. The ACTION-IF-FOUND and ACTION-IF-NOT-FOUND arguments are optional, and should also be specified as for PKG_CHECK_MODULES. ACTION-IF-FOUND is evaluated if the full LIST-OF-MODULES is found; ACTION-IF-NOT-FOUND similarly.
PUBLIC-VARIABLE defaults to AX_PACKAGE_REQUIRES, and PRIVATE-VARIABLE defaults to AX_PACKAGE_REQUIRES_PRIVATE. Both variables are AC_SUBST-ed by this macro.
For example:
AX_PKG_CHECK_MODULES([GLIB],[glib-2.0 gio-2.0],[gthread-2.0]) AX_PKG_CHECK_MODULES([DBUS],[],[dbus-glib-1 >= 0.98 dbus-1])
results in the substitutions:
AX_PACKAGE_REQUIRES="glib-2.0 gio-2.0" AX_PACKAGE_REQUIRES_PRIVATE="gthread-2.0 dbus-glib-1 >= 0.98 dbus-1"
and can be used with a template pkg-config file (.pc.in) using:
Requires: @AX_PACKAGE_REQUIRES@ Requires.private: @AX_PACKAGE_REQUIRES_PRIVATE@
