I'm seeing the same problem with gcc 4.6 trunk (r168937) for building a cross
compiler with target arm-unknown-eabi configured with newlib in tree.  The
crucial bit is --enable-multilib, without this option the problem is not
reproducible.

It looks like the --enable-multilib enables building the multilibs of the host
(instead of the target) for zlib.  In my case the host is (on Ubuntu 10.04):

$ gcc -dumpmachine
x86_64-linux-gnu
$ gcc -print-multi-lib
.;
32;@m32

I've attached my buildlog and the full content of gcc builddir subdirectories
'zlib' and '32/zlib' (the latter not present when --enable-multilib is
omitted).

Also like the original bug reporter is saying: I can avoid this problem by
specifying --with-system-zlib.

You shouldn't ever need to pass --enable-multilib explicitly to toplevel
configure, as multilib is enabled by default.  On top of that, there is a bug
currently in that explicit --enable-multilib is handled wrongly, see PR 43328.

I found that there is a problem with the gcc compiler that shipps with
Ubuntu. If you build the gcc compiler from scratch for Linux, then the
build for the arm works.

[Bug bootstrap/45174] New: Make fails in zlib

[dschlic1 at gmail dot com]

Cross compiler to arm bare metal fails during make in zlib. If configured with
--with-system-zlib, make succeeds. I have an automated script which allows
easier detection.

The first compile of GCC should be with only C and configured with
--with-newlib. And then a normal make instead of a make all-gcc. And a normal
make install.

config.log excerpt from zlib:

configure:7903: result: yes
configure:7936: checking whether the gcc  -m64 linker (ld) supports shared
libraries
configure:9020: result: yes
configure:9265: checking dynamic linker characteristics
configure:9710: error: Link tests are not allowed after GCC_NO_EXECUTABLES.

which corresponds to this code in zlib/configure, from AC_PROG_LIBTOOL:

  lt_cv_shlibpath_overrides_runpath=no
    save_LDFLAGS=$LDFLAGS
    save_libdir=$libdir
    eval "libdir=/foo; wl=\"$lt_prog_compiler_wl\"; \
         LDFLAGS=\"\$LDFLAGS $hardcode_libdir_flag_spec\""
    if test x$gcc_no_link = xyes; then
  as_fn_error "Link tests are not allowed after GCC_NO_EXECUTABLES." "$LINENO"
5


Either GCC or the user needs to prime cache variables in the way this test
shows:
<http://git.savannah.gnu.org/cgit/libtool.git/tree/tests/no-executables.at>
(There is currently one item missing there for AIX, which is relevant for GCC
but irrelevant to this particular PR).

This same issue supposedly holds for other GCC directories in which
GCC_NO_EXECUTABLES is used; it might just be latent.

Question is, what values the variables should be primed with.  In general,
tough one.  In this specific case: find out whether your linker sets DT_RUNPATH
upon -Wl,-rpath ("yes") or only DT_RPATH ("no").  Pass
lt_cv_shlibpath_overrides_runpath=no or =yes to configure accordingly.  Hmm. 
How can I ensure this primes the cache for host directories only?

>      Can you put that in layman's terms?

Yes; sorry for the complicated and technical response.  As far as I can see,
there is at the moment no simple way to avoid this issue with a configure
command-line switch, so I'll describe an approach that hopefully works around
the issue for now:

In the build tree where the error occurred, there should be an empty file named
something like:

  arm-unknown-elf/zlib/config.cache

Please open that file with a text editor and add the line

  lt_cv_shlibpath_overrides_runpath=no

Then rerun make.  Please report back if that works or not; if it doesn't, then
find the first error message in the output and cut and paste 50 lines of output
from a few lines above that error message. Thanks.

I'll write to the gcc list about how to improve configury so that this
hopefully becomes easier or unnecessary in the future.

------- Comment #16 from dschlic1 at gmail dot com  2010-08-07 00:18 -------
Subject: Re:  Make fails in zlib

Hello;
        I changed the value of lt_cv_shlibpath_overrides_runpath (it was set to
the result of an equality statement). No joy. The log is attached.
Results from the terminal are:

donald@donald-desktop:~$  sh Try15.sh /home/donald arm-elf 5
Found Linux OS.
******************************************************************
* Building gcc-4.5.1-boot
******************************************************************
make[3]: *** No rule to make target `all'.  Stop.
make[2]: *** [multi-do] Error 1
make[1]: *** [all-multi] Error 2
make: *** [all-zlib] Error 2
make: *** Waiting for unfinished jobs....
donald@donald-desktop:~$ 

        Previously to placing this bug report, I tried to find the source of
the error. The error occurs in this piece of code from configure in the
zlib source directory:

if test "${lt_cv_ld_exported_symbols_list+set}" = set; then :
  $as_echo_n "(cached) " >&6
else
  lt_cv_ld_exported_symbols_list=no
      save_LDFLAGS=$LDFLAGS
      echo "_main" > conftest.sym
      LDFLAGS="$LDFLAGS -Wl,-exported_symbols_list,conftest.sym"
      if test x$gcc_no_link = xyes; then
  as_fn_error "Link tests are not allowed after GCC_NO_EXECUTABLES."
"$LINENO" 5
fi

This piece of code is executed twice, first with
lt_cv_ld_exported_symbols_list set to blank, and gcc_no_link set to
blank. lt_cv_ld_exported_symbols_list is set to no because the else part
of the if statement is executed. Because gcc_no_link is not set, no
error is triggered.

However on the second pass, lt_cv_ld_exported_symbols_list has lost its
value (is blank), however gcc_no_link is set to yes. Result error. I
have not found out why lt_cv_ld_exported_symbols_list loses its value on
the second pass. LDFLAGS also loses its value on the second pass.

Thank You,
Donald Schlicht

Hello;
        I am afraid I messed up my system. I was playing around trying to
install the latest versions of binutils and gcc on my linux system
(native, not cross compile), and now I am getting a different error. In

It looks like configure is trying to compile sources to 64 bit. I am
running a 32 bit system. Any ideas on how to tell configure to compile
for a 32 bit linux box?

You are not cross-building for arm-unknown-elf any more, so the error you are
getting has nothing to do with this PR any more.  Please get your system in
order first, I cannot help you with that, and I'm afraid people working on GCC
PRs don't really have the resources to help with that.  Their primary interest
is in fixing GCC.  I think this PR is probably valid but don't have the
resources to confirm myself.

If you want to create a native compiler on x86-linux, try disabling multilibs
as documented in the installation manual (and please follow up on the gcc-help
list if you have questions regarding that).

the latest native binutils and gcc-4.5.1 on my linux installation. The

        However it appears that using the supplied binutils and compilers from

I've just read this thread and am now unsure as to whether there is a bug with
GCC or not.  It sounds like your initial troubles have gone away and now there
is a new problem.  Would it make sense to close this bug and raise a new bug to
cover the new issue?

I've just read this thread and am now unsure as to whether there is a bug with
GCC or not.  It sounds like your initial troubles have gone away and now there
is a new problem.  Would it make sense to close this bug and raise a new bug to
cover the new issue?

It would make sense to treat any issues that Donald has in a new PR (after
making sure they are not setup problems).

However, I am fairly sure that comment #13 describes a real issue, as it has
been reported to Libtool before, and there is a Libtool testsuite addition that
exposes link tests in AC_PROG_LIBTOOL that are not guarded by a cache variable.

The issue described by #13 may be latent in GCC.  I haven't tried to reproduce
it there yet.
