Subject: Re: [patch, mips] Fix stubs files for hard float vs. soft float

Message-ID: <20121024172501.AA6E52C0A5@topped-with-meat.com> (raw)
In-Reply-To: Steve Ellcey's message of  Wednesday, 24 October 2012 10:12:41 -0700 <1351098761.15035.52.camel@ubuntu-sellcey>

There is a completely generic pattern rule near the top of Makefile that
handles this.  What must be missing is the dependency on that configure
script.  The config.status target in Makeconfig is where that dependency
should be.  The usual method to debug this sort of thing is to copy
verbatim the text of the dependency list into the ... place in:

foo:=$(shell echo>&2 'XXX ...')

and then look for the XXX on stderr to see the expansion.  If it omits any
configure fragments that are getting run by configure, then figure out
where the expansion is going wrong.  You can slice up the nested variable
expansions to print out intermediate values via debugging hacks as above
to figure out why it's not right.


Thanks,
Roland
