Bug #: 13835
Summary: Build fails on SLES 10 (PPC)
Product: gdb
Version: HEAD
Status: NEW
Severity: normal
Priority: P2
Component: build
AssignedTo: ***@sourceware.org
ReportedBy: ***@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
ada-exp.c.tmp \

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.

I'm going to close this on account of age and also because there
is a workaround.
Please reopen if is still relevant.
