sys-devel/libtool-2.2.4: When creating shared libraries libtool adds dependencies of specified libraries which causes needless linking against additional libraries.

sys-devel/libtool-1.5.26 works correctly.

(In reply to comment #1 and comment #2)

There should be:
$ scanelf -qF "%F: %n" .libs/libtool_test.so.0.0.0

Instead of:
$ scanelf -qF %F: %n .libs/libtool_test.so.0.0.0

Maybe this is related to the following patch applied in debian:

Comment 8 Opportunist 2009-06-28 09:02:52 UTC

any news?

Comment 9 Yaroslav Isakov 2016-02-14 20:25:54 UTC

I'm here from 2016 :) It seems that it is fixed for sys-devel/libtool-2.4.6, sys-devel/gcc-4.9.3 and x86_64 arch. Please confirm on other platforms.

$ scanelf -qF "%F: %n" .libs/libtool_test.so.0.0.0
.libs/libtool_test.so.0.0.0: libapr-1.so.0,libaprutil-1.so.0,libc.so.6

make sure you aren't using the gold linker or --as-needed.  both of those will fix up the excess linkage.

Comment 11 Yaroslav Isakov 2016-02-14 20:56:38 UTC

Yeah, you're right, I'm using LDFLAGS="-Wl,-O1 -Wl,--as-needed"

But it's in default profile, so probably it's fixed on every installation (besides of custom LDFLAGS users)
