# AC_CHECK_FRAMEWORK(FRAMEWORK, FUNCTION,

# ------------------------------------------------------

#
|
|
# Use a cache variable name containing both the framework and function name,
|
|
# because the test really is for framework $1 defining function $2, not
|
|
# just for framework $1. Separate tests with the same $1 and different $2s
|
|
# may have different results.
|
|
#
|
|
# Note that using directly AS_VAR_PUSHDEF([ac_Framework], [ac_cv_framework_$1_$2])
|
|
# is asking for troubles, since AC_CHECK_FRAMEWORK($framework, fun) would give
|
|
# ac_cv_framework_$framework_fun, which is definitely not what was meant. Hence
|
|
# the AS_LITERAL_IF indirection.
|
|
#
|
|
# FIXME: This macro is extremely suspicious. It DEFINEs unconditionally,
|
|
# whatever the FUNCTION, in addition to not being a *S macro. Note
|
|
# that the cache does depend upon the function we are looking for.
|
|
#
|
|
# It is on purpose we used `ac_check_framework_save_LIBS' and not just
|
|
# `ac_save_LIBS': there are many macros which don't want to see `LIBS'
|
|
# changed but still want to use AC_CHECK_FRAMEWORK, so they save `LIBS'.
|
|
# And ``ac_save_LIBS' is too tempting a name, so let's leave them some
|
|
# freedom.
