This is fixed in gcc 4.7.2 or later. For the workaround, see: http://www.tilera.com/scm/source.html#feedback_h Essentially, you just have to create a dummy <feedback.h> header, e.g. for 4.7.1: cat > $install/lib/gcc/tilegx-unknown-linux-gnu/4.7.1/include/feedback.h #define FEEDBACK_ENTER_EXPLICIT(FUNCNAME, SECNAME, SIZE) #define FEEDBACK_ENTER(FUNCNAME) #define FEEDBACK_REENTER(FUNCNAME) #define FEEDBACK_ENTRY(FUNCNAME, SECNAME, SIZE) ^D -- Chris Metcalf, Tilera Corp. http://www.tilera.com -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
