Heh.
Ok, I confess, I wasn't complete.
Here's something closer to what I have to do (the actual
code is much more complicated):
define some_func
target: $$($(1))
echo '$$' > $$@
endef
my_func = $(eval $(call some_func,$(1)))
The $$' gets evaluated by the eval and thus disappears, causing a shell parse
error:
cd make -f test.mk target
Done!
echo ' > target
/bin/sh: -c: line 0: unexpected EOF while looking for matching `''
/bin/sh: -c: line 1: syntax error: unexpected end of file
make: *** [target] Error 2
Is there a way to protect the evaluation of $ in a define section?
