Description Denis Kaganovich 2009-08-10 14:20:25 UTC 
sys-libs/libstdc++-v3-3.3.6 build failed: trying to use unfiltered system-wide CPPFLAGS with self-compiled xgcc (gcc 3.3.6).

To reproduce just add any "new" gcc flag into CPPFLAGS (-msse4.1 or -fivopts or -ftree-loop-linear):
CPPFLAGS="-ftree-loop-linear" emerge -1 libstdc++-v3

Solution: add 'CPPFLAGS=""' or 'CPPFLAGS="${CFLAGS}"' into "emake" commandline.
(attaching in patch form)


Reproducible: Always

Comment 2 Ryan Hill (RETIRED) gentoo-dev 2009-08-15 17:34:28 UTC 
Why are you putting those flags in there in the first place?  CPPFLAGS are flags that are passed to the preprocessor.  Those flags aren't preprocessor flags.  Are you mixing it up with CXXFLAGS?
