             Bug #: 13835
           Summary: Build fails on SLES 10 (PPC)
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: build
        AssignedTo: unassigned@sourceware.org
        ReportedBy: chris.january@allinea.com
    Classification: Unclassified


Building today's HEAD on SLES 10 SP1 (PPC970) host fails due to missing
prototypes for some yy* functions in ada-lex.c.

Target: powerpc64-suse-linux
gcc version 4.1.2 20070115 (prerelease) (SUSE Linux)
bison (GNU Bison) 2.1

Removing -Wmissing-prototypes from WARN_CFLAGS in Makefile allows the build to
continue.

rm -f ada-exp.c ada-exp.c.tmp
/bin/sh ./../ylwrap ada-exp.y y.tab.c ada-exp.c -- bison -y  && mv ada-exp.c

Confirmed, I see this as well.  Can this be fixed please?

You can always configure with --disable-werror.

I also confirm this is still happening on upstream gdb. This seems to be due to
an old version of flex on SLES10 (flex 2.5.31), and is not reproducible if
you're using 2.5.35.
As suggested by Andreas, './configure --disable-werror' also avoids the
problem.
