Bugzilla Bug 114719

configure thinks something has changed in the environment, namely a space added
in CFLAGS (as defined in /etc/make.conf)

Reproducible: Always
Steps to Reproduce:
1.emerge kdebase
2.
3.

Actual Results:  
configure: loading cache .././config.cache
configure: error: `CFLAGS' has changed since the previous run:
configure:   former value:  -march=pentium4 -O3 -pipe -fomit-frame-pointer
-ffast-math  -mfpmath=sse
configure:   current value: -march=pentium4 -O3 -pipe -fomit-frame-pointer
-ffast-math -mfpmath=sse
configure: error: changes in the environment can compromise the build
configure: error: run `make distclean' and/or `rm .././config.cache' and start over
configure: error: /bin/sh './configure' failed for saslauthd


I think google shows few hits on this issue, but non in gentoo related sites.

if you change:
CFLAGS="-march=athlon-xp -O3 -pipe -fomit-frame-pointer"
in your make.conf and then emerge does it work?

Sorry Sorry Sorry.
I got emerge info from the wrong host...
this is the correct one

and did you try emerging with the CFLAGS i posted before?

> and did you try emerging with the CFLAGS i posted before?

yes,
with
CFLAGS="-march=pentium4 -O3 -pipe -fomit-frame-pointer -ffast-math -mfpmath=sse"

shortened to 
CFLAGS="-march=pentium4 -O3 -pipe -fomit-frame-pointer"

It emerged sucessfully.

The strange thing is that 'emerge info' reported double space between
-ffast-math and -mfpmath=sse in CFLAGS, while in make.conf there was only a
single space between them.

While it shouldn't break, cyrus-sasl is known to have a problem with double
spaces in CFLAGS. In this case i'm going to mark this as invalid and just ask
you to ensure that your CFLAGS is correct formatted. There was a belief that the
CFLAGS manipulation we were doing in the ebuild should have fixed this problem,
but obviously it hasn't. We will remove it shortly after verifying its not used
for anything else.

Reopen to dupe.
