./stdio.h:477:1: error: 'gets' undeclared here (not in a function)解决
今天编译一个bsp包时，出现如下错误，简直不知道为嘛，按理说官方给的bsp包没什么问吧，但在ubuntu 13.4下编译，出现如标题的错误，于是只能google,问题是解决了
I hope you are all well.
Glibc-2.16.0 has been released
http://ftp.gnu.org/gnu/glibc/glibc-2.16.0.tar.xz
The good news is that it no longer needs the patches that are in
current LFS. However, there are still some problems with it. Firstly,
the libgcc_s.so
issue:
/mnt/lfs/tools/bin/../lib/gcc/x86_64-lfs-linux-gnu/4.7.1/../../../../x86_64-lfs-linux-gnu/bin/ld:
cannot find -lgcc_s
collect2: error: ld returned 1 exit status
make[2]: *** [/mnt/lfs/sources/glibc-build/iconv/iconv_prog] Error 1

make[2]: Leaving directory `/mnt/lfs/sources/glibc-2.16.0/iconv'
make[1]: *** [iconv/others] Error 2
make[1]: Leaving directory `/mnt/lfs/sources/glibc-2.16.0'
make: *** [all] Error 2
Fixed by:
sed -i 's# -lgcc_s##' Makeconfig
(We won't hit the libgcc_s.so problem with Gcc until we start using
Gcc-4.7.2)
Then an error due to a problem with gcc:
/mnt/lfs/sources/glibc-build/resolv/libresolv_pic.a(gethnamaddr.os): In function `getanswer':
/mnt/lfs/sources/glibc-2.16.0/resolv/gethnamaddr.c:180: undefined reference to `__stack_chk_guard'

make[1]: Leaving directory `/mnt/lfs/sources/glibc-2.16.0'
make: *** [all] Error 2
Fixed by this sed in the gcc source before the first pass of gcc:
sed -i '/k prot/agcc_cv_libc_provides_ssp=yes' gcc/configure
Then a simple problem with the rpc headers:
glibc-build/config.h rpc_tblout.c /
-o /mnt/lfs/sources/glibc-build/sunrpc/cross-rpc_tblout.o -MMD -MP -MF
/mnt/lfs/sources/glibc-build/sunrpc/cross-rpc_tblout.o.dt -MT
/mnt/lfs/sources/glibc-build/sunrpc/cross-rpc_tblout.o -c
rpc_clntout.c:34:23: fatal error: rpc/types.h: No such file or directory
compilation terminated.

make[1]: *** [sunrpc/others] Error 2
make[1]: Leaving directory `/mnt/lfs/sources/glibc-2.16.0'
make: *** [all] Error 2
Fixed by:
sed -i 's#<rpc/types.h>#"rpc/types.h"#' sunrpc/rpc_clntout.c
There's lots of gets removal breakage.

make: *** [all] Error 2
Fixed with a sed:
sed -i '/gets is a security hole/d' gnu/stdio.in.h
And so into chroot.
Glibc fails with the rpc/types.h error again. It seems crazy to me that
it tries to use the system header not the in-tree one but what do I
know?:
sed -i 's#<rpc/types.h>#"rpc/types.h"#' sunrpc/rpc_clntout.c
Again, the glibc patches are not needed.
test-installation.pl failed with an error:
test ! -x /sources/glibc-build/elf/ldconfig || LC_ALL=C LANGUAGE=C /
/sources/glibc-build/elf/ldconfig /
/lib64 /usr/lib64

$(abi-64-ld-soname),$(abi-64-ld-soname),ld/ at scripts/test-installation.pl line 172, <LDD>
line 1.
make[1]: *** [install] Error 29
make[1]: Leaving directory `/sources/glibc-2.16.0'
make: *** [install] Error 2
root:/sources/glibc-build# cd /sources/glibc-2.16.0

$(abi-64-ld-soname),$(abi-64-ld-soname),ld/ at scripts/test-installation.pl line 172, <LDD>
line 1.
So I disabled running test-installation.pl:
sed -i '/test-installation.pl/d' Makefile
I'm sure there is a more subtle fix for this but I don't have time just
now.
And speaking of time; timezones. Timezone data are not part of glibc
anymore:
cp: cannot stat '/usr/share/zoneinfo/Europe/London': No such file or directory
I have to install a new package tzdata2012c
http://www.iana.org/time-zones:
for thing in etcetera southamerica northamerica europe africa antarctica /
asia australasia backward pacificnew solar87 solar88 solar89 systemv
do zic -L /tmp/tzdata/leapseconds -d /share/zoneinfo /
-y "sh ~/tzdata/yearistype.sh" /tmp/tzdata/${thing}
done
cp /usr/share/zoneinfo/Europe/London /etc/localtime
And then we're back to the gets breakage grind. M4, inetutils,
diffutils, gettext, grub, libpipeline, man-db and Tar all need
variations on the gets sed. Eg,for Gettext in chroot it's now:
sed -i '/gets is a security hole/d' /
gettext-{runtime/gnulib-lib,tools/{gnulib-lib,libgettextpo}}/stdio.in.h
I should confess that (as I'm a devotee of the Klingon School of
Programming) I didn't run any of the tests, so there may be some more
bugs under those rocks.
