Re: [HELP] PHONY pattern rule makes the file w/ the same name

[Bahman Movaqar]

Hit "Send" too soon.


To make matters more complicated, in the previous snippet, if I declare
`echo.%' as below (w/o any pattern-rule prerequisite) then Make behaves
as expected.

—————————————————————————————————————————————————————————————————

####################################################
# ./mk/echo.mk
####################################################

.PHONY : echo.%

echo.% :
        @echo 'echo invoked with "$(*)"'

####################################################
# shell
####################################################

$ make echo.hello-there

echo invoked with "hello-there"

—————————————————————————————————————————————————————————————————

🤯
