Description FUCHIGAMI Masachika 2009-10-14 14:30:02 UTC
local variable substitution in dependency source fails when $@ is used in another variable name ( e.g. ${$(@)_SRC} ).

make(1) delayes load-time variable substitution for local variables by expanding local variables to itself ( $@ -> $@ ), but make(1) does not delay variables containing local variables.

How-To-Repeat: -- Makefile
foo=bar
foo: $($@).txt
--
% touch bar.txt
% make foo
make: don't know how to make .txt. Stop
