Summary: error in compiling libstdc++ with -std=gnu++0x
Product: gcc
Version: 4.6.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: vincenzo.innoce...@cern.ch
I tried to compile gcc with a subset of the CXXFLAGS I use in my project
echo $CXXFLAGS
-O2 -std=gnu++0x -ftree-vectorize -Wall -fvisibility-inlines-hidden
-fpermissive
I got this compilation error that may be worth fixing
