Jonathan Wakely <redi at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution|--- |INVALID --- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to zosrothko from comment #0) > $ gcc -xc++ -std=gnu++11 -o foo foo.c To link a C++ program you should explicitly link to the C++ runtime library, using -lstdc++, or use g++ which does that automatically. (If your source file is C++ why is your file called foo.c instead of having a C++ file extension?)
