Unable to build glibc

quequotion · 2015-06-07 04:44:29

Glibc consistently fails at this point:

checking for .preinit_array/.init_array/.fini_array support... no
configure: error: Need linker with .init_array/.fini_array support.

Both ABS and AUR (git) versions fail in the same place.

I have tried to compile both native (64bit) and lib32 packages.

I have tried this with both ABS and AUR (git) versions of binutils.

I have tried with and without LTO (someone was getting that error related to LTO, but not my case).

I have tried to use the standard linker, ld.bfd but my system seems fixated on ld.gold (even when lto is disabled). My choice of linker is not recognized, and I cannot fathom why ld.gold seems to be default; it would seem I have no say in the matter. In either case, ld.gold should not cause these problems.

I even tried commenting out the error thrown by this section of the configure script (in case the test itself is broken) but the next test also failed:

checking for .preinit_array/.init_array/.fini_array support... no
checking whether to use .ctors/.dtors header and trailer... configure: error: missing __attribute__ ((constructor)) support??

What in the world?

Builds fine here. Can you show us the whole configuration log?

--edit:

Are you using any custom {C, CPP, CXX, MAKE}FLAGS?

Have at it! This log is from a lib32-glibc attempt. There's something seriously weird going on here: "Configured with" shows a configure script and options that are from another package, my custom version for mmug, which are in a completely different directory than this and are not involved in this compilation attempt by any action on my part.

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by GNU C Library configure (see version.h), which was
generated by GNU Autoconf 2.69.  Invocation command line was

  $ /var/tmp/yaourt-tmp-quequotion/abs-lib32-glibc/src/glibc-2.21/configure --prefix=/usr --libdir=/usr/lib32 --libexecdir=/usr/lib32 --with-headers=/usr/include --with-bugurl=https://bugs.archlinux.org/ --enable-add-ons --enable-obsolete-rpc --enable-kernel=2.6.32 --enable-bind-now --disable-profile --enable-stackguard-randomization --enable-lock-elision --enable-multi-arch --disable-werror i686-unknown-linux-gnu

Are you using any custom {C, CPP, CXX, MAKE}FLAGS?

Only -O3 and -fstack-protector-all; both are problem-free 99.9% of the time.

I did a test build with -O2 and without -fstack-protector-all, which fails in a different place:

/var/tmp/yaourt-tmp-quequotion/abs-lib32-glibc/src/glibc-build/elf/librtld.os:rtld.c:function lookup_doit: error: undefined reference to '__stack_chk_fail_local'

/var/tmp/yaourt-tmp-quequotion/abs-lib32-glibc/src/glibc-build/elf/librtld.os:rtld.c:function dl_main: error: undefined reference to '__stack_chk_fail_local'

These errors could not be resolved by:
-fno-stack-protector (in CFLAGS, no change; build failed wtith the same stack-protector related errors)
-lssp (in LDFLAGS, causes build to fail; apparently makes the linker unusable)

Can you try to build it with makepkg instead of yaourt and see if it works?

I did; there was no difference.* Yaourt is not configured to alter makepkg's options.

*The log posted above is from a makepkg build; the files happen to be in yaourt's tmp dir.

Have you done a web search for the errors you are seeing? I get several hits for all of them.

And tried most of the proposed solutions, so I am asking here.

In particular, the error message I got is attributed to LTO, but I get the error with or without LTO.

That is what i did. The above errors were output.

I usually delete src/ and pkg/ before every build; Maybe I forgot after changing to -fno-stack -protector... I've been rebuilding this package continuously all day... ::EDIT:: Nope, not getting that sloppy yet. The "undefined refrence" errors to stack protector functions are still a problem.

Is there a way I can find out why specifying "-lssp" in LDFLAGS kills the linker? (the proposed to solution for this problem) When used during a build, I don't get any output from ld or gcc; configure just says it can't find a compatible linker and dies.

Ok, so the error can be reproduced. That's good news. Now to figure out why the solution doesn't work for me...

The option -lssp should be passed to the compiler through CFLAGS and/or CPPFLAGS and/or CXXFLAGS and not to the linker. However that will be only a workaround and not a solution.

Does the configuration log still say that the configuration was done using your custom version for mmug? Because it seems you are using an experimental version of gcc

I also noticed you are still using 3.19.2-1-ck kernel while current version is 4.0.5-1-ck: is your system fully updated?

The later is what I thought, that it shouldn't be necessary in any case (especially for just the one package), but I will try putting this flag in C{,PP,XX}FLAGS as well...

The mmug version is indeed experimental (git) but the version I have (most recetnly) been trying to build is from ABS. I cannot account for why there would be references to the other package in this one... that's insane....

I also noticed you are still using 3.19.2-1-ck kernel while current version is 4.0.5-1-ck: is your system fully updated?

This has come up during a full upgrade (yaourt -Syub). For now I've installed the binary packages to be able to continue upgrading, but that is not a solution. I need to patch lib32-glibc (for mmug), and I was hoping to try out the "--enable-kernel=" option.

Building lib32-glibc in a clean chroot with hardening-wrapper installed fails

Ah hah! Is there a way to temporarily disable the hardening-wrappers? I could purge the whole package, rebuild glibc, and reinstall it (I'd rather keep the added security); but I have a feeling this could happen again and possibly to other packages.

Since the compilers provided by hardening-wrappers are wrappers, the will override the options you set in makepkg.conf or in the environment variables. In order to change the options globally, you have to edit the file /etc/hardening-wrapper.conf. In particular the stack protector option is controlled by the variable HARDENING_STACK_PROTECTOR:

HARDENING_STACK_PROTECTOR=0 means it will use the compiler default option or the option already passed to the compiler.
HARDENING_STACK_PROTECTOR=1 means -fstack-protector
HARDENING_STACK_PROTECTOR=2 means -fstack-protector-strong
HARDENING_STACK_PROTECTOR=3 means -fstack-protector-all

But if you want override the options only for one package, you can use a command like the following:

HARDENING_STACK_PROTECTOR=0 makepkg

I believe both arch and hardenning wrapper default to -fstack-protector-strong. If you have default settings in your makepkg.conf, it doesn't make sense that you should have a conflict there--unless gcc doesn't like having more than one of these options specified. I had both -fstack-protector-strong and -fstack-protector-all in makepkg for ages with no problems, and later switched to just -fstack-protector-all when I understood the redundancy.

In any case, in the course of attempting to fix this bug and many others, I spent three weeks putting arch back together and then one day it just wouldn't boot anymore. I probably could have scrounged some fix together, but I gave in, backed up my data, and formatted.

mauritiusdadd · 2015-07-20 12:01:12

I think the actual problem here is not the conflict between the two options, but the fact that glibc does not build with any of the stack protector option (there is also an old bug report that has been reopened https://sourceware.org/bugzilla/show_bug.cgi?id=7065). Even if -fstack-protector-strong is set by default in makepkg.conf, that option is passed trough the environment variables CFLAGS and CPPFLAGS but you still have to specify in the Makefile if and how to use that variables. This give you the ability to decide which file can be compiled with custom options and which should be compiled with the default ones. However the gcc wrapper provided by hardening-wrapper will force every file to be compiled with the stack protector option you specified in the configuration file.

For example let's assume that CFLAGS="-fstack-protector-strong". Using the default /usr/bin/gcc compiler,

gcc $CFLAGS -lm file1.c
gcc -lm file2.c

the above code is expanded by the shell to

/usr/bin/gcc -fstack-protector-strong -lm file1.c
/usr/bin/gcc -lm file2.c

and the result is that only file1.c is compiled with -fstack-protector-strong. Now if we use the hardening wrapper, gcc is replaced by /usr/lib/hardening-wrapper/bin/gcc which in turn invokes the compiler with the options specified in /etc/hardeing-wrapper.conf, so the above commands become (assuming the default configuration is used)

/usr/bin/gcc -fPIE -D_FORTIFY_SOURCE=2 -fstack-protector-strong -fstack-protector-strong -lm file1.c
/usr/bin/gcc -fPIE -D_FORTIFY_SOURCE=2 -fstack-protector-strong -lm file2.c

and the effect is that both files are compiled with -fstack-protector-strong (that is the purpose of the wrapper).

Look at the glibc PKGBUILD. It explicitly disables stack protection for part of the build.

True, but it affects only the CFLAGS and CPPFLAGS

  # remove hardening options for building libraries
  CFLAGS=${CFLAGS/-fstack-protector-strong/}
  CPPFLAGS=${CPPFLAGS/-D_FORTIFY_SOURCE=2/}

Doesn't the wrapper still pull in that option as it is enabled in the configuration file?

--edit[0]: yes, it seems it does it: after adding the option --verbose to CFLAGS, the output shows

So the option -fstack-protector-strong is still there.

--edit[1]: just for the record, this issue appears to affect only the multilib version and the x86_64 version builds just fine even using the hardening wrapper
