# audacity_checklib_widgetextra.m4 serial 1
|
|
|
|
dnl A function to check for the correct presence of lib-widget-extra in the
|
|
dnl lib-src tree. Note that this is a mandatory library, and
|
|
dnl that because we maintain it, we don't support system copies.
|
|
|
|
dnl You would have thought you could use pkg-config for this. But the
|
|
dnl pkg-config file doesn't exist until configure has been run for
|
|
dnl lib-widget-extra. Using AC_CONFIG_SUBDIRS, that doesn't happen until
|
|
dnl after everything in the main configure script has happened, so
|
|
dnl we can't detect anything about the configured library, because it isn't
|
|
dnl configured when this runs.
|
|
dnl To get round this we have created our own subdirectory configuration
|
|
dnl function, AX_CONFIG_DIR based on a subset of the code that implements
|
|
dnl AC_CONFIG_SUBDIRS.
|
|
|
|
AC_DEFUN([AUDACITY_CHECKLIB_WIDGETEXTRA], [
|
|
dnl we always need to configure libwidgetextra, so just call the script
|
|
dnl regardless.

|
|
dnl having done that we get a pkg-config file we can use
|
|
dnl add the directory with lib-widget-extra in to the pkg-config search path
