RE: Using $(eval) to get information at the time a target is invoked

[Hsu, Shihchieh IAS]

I am new to $(eval) and can only present my wishful thinking:

When "all" is invoked, it will go through $(eval) , $(wildcard), etc and save 
the information, but apparently, the information is also saved when makefile 
was scanned (???)

Any suggestion to dump cache information on Linux?  I vaguely remember there is 
some debugging/trace capabilities in make.

Maybe I don't understand something, but $(eval) calls
$(PROGRAM_template), which calls $(wildcard).  So $(wildcard) is still
involved.  And in GNU Make, $(wildcard) uses a cache that stores the
contents of directories.
