Details:
Using a simple makefile under Windows 7, it became apparent that the wildcard
function does not reflect the existence of a library created when the first
object was added to it.
This is make 3.81, as downloaded from gnuwin32:
GNU Make 3.81

C:\Users\admin\dev\lib\ll
The attached listing shows both the GNUmakefile, and the resulting output
showing that $(wildcard ll.lib) does not recognize the existence of the
library after it was created.
However, my workaround $(mywildcard) gives the correct results one would
expect from the wildcard function. This is consistent with the mention that a
cache is probably used to avoid actually checking the filesystem and can
therefore cause inconsistent results. Curiously, repeated tests showed that
occasionally the wildcard function would begin showing the existence of the
library file in the middle of building and adding the eight object files. But
usually it would not recognize the file until the make was run a second time.
Thank you,
Harry Clauson
