Variables within Pattern Rules

[Barry Clarkson]

Hi,

How do you create a variable on the fly within a
pattern rule?

If I have two files called 'myfile.c' and
'anotherfile.c', a pattern rule for '(%.o) : %.c' I
want to be able to pass 'MYFILE_DEFS' and
'ANOTHERFILE_DEFS' as a define to $(CC) along the
lines of...

DEF=`echo $(basename $<) | tr '[a-z]' '[A-Z]'`_DEFS

...so that I can perform...

gcc -DMYFILE_DEFS myfile.c ...
gcc -DANOTHERFILE_DEFS anotherfile.c ...

...for each prerequisite.

Thanks in advance,

Barry
