RE: Tricky suffix rule problem for Corba

[CARTER-HITCHIN, David, FM]

Hi Paul,

Thanks for replying.  Sorry I didn't really finish my account of what
happens:  The .cc and .h files get created in the source dirs w,x,y or z,
and so when we rerun make it tries to find ../idl/a.cc or ../idl/a.h and of
course never finds them, so it rebuilds.

>     %.h ../idl/%.cc : ../idl/%.idl
>             $(IDL_COMMAND) $(IDL_OPTIONS) $<

I tried a few things like this.  The variation you give means the target is
still '../idl/gds_server.h' which is not where the header needs to live and
the pre-requisite is '../idl/../idl/gds_svc_man.idl' which looks broken but
we're just making make skip between dirs and is the same as what we've
started with.

Any other ideas?  I could hard code specific rules for these files but I'd
prefer to have a suffix rule if possible.

Thanks, 

David Carter-Hitchin.
