My build model has a common link line which contains a number of -z
options (-z is a way of passing keywords to the linker on Linux and
Solaris). For instance:
$(CC) -o program -z combreloc -z noversion -z defs ...
The problem is that occasionally a target will need one of these
removed as a special case. But of course using $(filter-out -z
foo,...) will remove *all* the -z flags, leaving the other keywords
hanging there alone, while quoting the string like $(filter-out "-z
foo",...) doesn't match anything. Does anybody know a reasonable way
to remove a whitespace-containing string? I can think of ways
involving $(shell) with but would prefer to do it all within the make
process. Another complication is that, because this needs to be
compatible with clearmake's GNU-compatibility mode, I'm limited to
those features available since GNU make 3.76 or so.
Thanks,
David Boyce
