Description Richard Biener 2012-12-04 13:24:27 UTC

> gcc -o libt1.so -shared -lm
> gcc -o libt2.so -shared -Wl,--copy-dt-needed-entries -L. -lt1

libt1.so is as expected:

> readelf -d libt1.so

Dynamic section at offset 0xe48 contains 22 entries:
  Tag        Type                         Name/Value
 0x0000000000000001 (NEEDED)             Shared library: [libm.so.6]
 0x0000000000000001 (NEEDED)             Shared library: [libc.so.6]
 0x000000000000000c (INIT)               0x480
...

but libt2.so does not have a NEEDED entry for libm.so.6:

> readelf -d libt2.so 

Dynamic section at offset 0xe48 contains 22 entries:
  Tag        Type                         Name/Value
 0x0000000000000001 (NEEDED)             Shared library: [libt1.so]
 0x0000000000000001 (NEEDED)             Shared library: [libc.so.6]
 0x000000000000000c (INIT)               0x480
...

(trying to come up with a testcase where --[no-]copy-dt-needed-entries matters)

Same behavior with ld 2.18 (and --[no-]add-needed) btw.  Same behavior
if libt2.so is not a shared object.

Comment 1 Michael Matz 2012-12-04 14:06:26 UTC

Behaviour also doesn't change if we include objects that refer to stuff from libm or libt1 into libt2.  I tried to debug ld a bit to see where this is supposed to be handled but got lost after two hours.  It seems that some
handling of dt_needed entries in elf32.xm:gld*_after_open is only done
for executables, but even creating an executable doesn't help.

In any case, I couldn't find any code that really tries to add DT_NEEDED
entries from referred libraries to the output file.  The code in elflink.c:elf_link_add_object_symbols at least only adds to the htab->needed
list on those entries (and 'libm.so.6' is included there), but doesn't actually call elf_add_dt_needed_tag on those entries (and nobody else does
either).

It certainly doesn't work as documented or expected (with my expectations).

Comment 2 H.J. Lu 2012-12-04 14:07:56 UTC

Please show the output of

gcc -o libt2.so -shared -Wl,--copy-dt-needed-entries -L. -lt1 -v

We need to see all command-line options passed to
linker.

/usr/lib64/gcc/x86_64-suse-linux/4.5/collect2 --build-id --eh-frame-hdr -m elf_x86_64 -shared -o libt2.so /usr/lib64/gcc/x86_64-suse-linux/4.5/../../../../lib64/crti.o /usr/lib64/gcc/x86_64-suse-linux/4.5/crtbeginS.o -L. -L/usr/lib64/gcc/x86_64-suse-linux/4.5 -L/usr/lib64/gcc/x86_64-suse-linux/4.5/../../../../lib64 -L/lib/../lib64 -L/usr/lib/../lib64 -L/usr/lib64/gcc/x86_64-suse-linux/4.5/../../../../x86_64-suse-linux/lib -L/usr/lib64/gcc/x86_64-suse-linux/4.5/../../.. --copy-dt-needed-entries -lt1 -lgcc --as-needed -lgcc_s --no-as-needed -lc -lgcc --as-needed -lgcc_s --no-as-needed /usr/lib64/gcc/x86_64-suse-linux/4.5/crtendS.o /usr/lib64/gcc/x86_64-suse-linux/4.5/../../../../lib64/crtn.o

So, the --copy-dt-needed-entries argument is at the right place, right before
-lt1.  During my debugging I of course used this cmdline (well, substed
collect2 with the right ld).  Changing various options like removing libs
or the --as-needed doesn't make a difference for the behaviour we expect.

Comment 4 H.J. Lu 2012-12-04 14:30:28 UTC

This option is renamed from --add-needed:

Yes, but why are you mentioning that?

Btw, I explicitely stated that even before the rename, with ld 2.18,
it did not work as expected (using --[no-]add-needed).

In particular, from that thread is referred the GCC problem that you wanted
to fix with adding --no-add-needed: http://gcc.gnu.org/ml/gcc/2004-04/msg01130.html

The problem specifically was that libunwind was added to DT_NEEDED because
it was itself DT_NEEDED by libgcc_s, and it was said that this was how the linker is supposed to work.  Now, meanwhile the default got switched, i.e.
--no-copy-dt-needed-entries is the default, but we're supposed to be able
to switch back with --copy-dt-needed-entries.  And this bug report is about
the fact, that this doesn't work.

Comment 8 Michael Matz 2012-12-04 14:56:09 UTC

Let's create a different testcase showing also similar symptoms of not correctly adding DT_NEEDED entries as documented, this time to search scopes:

% cat bla.c
extern double sin (double);
double f (double i) { return sin (i); }
% gcc -c -fPIC bla.c
% ./ld/ld-new -shared -o libt1.so bla.o -lm -zdefs
% readelf -d libt1.so | grep NEEDED
 0x0000000000000001 (NEEDED)             Shared library: [libm.so.6]

Everything fine so far.  Now we want to generate libt2 also referring
to a libm function, want to link it only with libt1 and expect that
there's some way to include libm into the search scopes with some option to ld.  The documented option is --copy-dt-needed-entries, so:

% cat bla2.c
extern double f (double);
extern double sin (double);
double g (double i) { return f(i) + sin (i); }
% gcc -c -fPIC bla2.c

So, bla2 refers to functions of libt1 and to libm, but still:

% ./ld/ld-new -shared -o libt2.so bla.o --copy-dt-needed-entries -L. -lt1 -z defs
bla2.o: In function `g':
bla2.c:(.text+0x22): undefined reference to `sin'

Comment 9 H.J. Lu 2012-12-04 18:21:46 UTC

--copy-dt-needed-entries doesn't work when -shared is used.
