When I run that little test code above with
GNU gold (GNU Binutils for Ubuntu 2.22) 1.11
I get:
gcc -Xlinker --no-as-needed -Xlinker

When using gold you need to list the shared libraries that define symbols that
you refer to directly. You do not need to list libraries that define symbols

Please make gold accept and ignore the --no-add-needed switch so there is a
single command line that has the same semantics for both ld implementations.

IMO, ld's automagic searching is a good thing. Asking a program to enumerate
all the indirect dependencies of shared libraries is a burden that they may not
be equipped to carry. How do you envision this be

Pretty common, based on the link in comment #7. The vast majority of those
failures are due to unresolved symbols, and it's possible many (most? virtually
all?) of them are due to programs expecting the old

Comment #7 does not necessarily indicate that there are a lot of packages which
provide a union-of-defined-symbols interface. What is indicates is that a lot
of people think that linking against the KDE or GNOME

I'm confused about whether gold's lack of DT_NEEDED resolution is
intended to affect only pure-indirect or merely mixed-direct-indirect
dependencies. Specifically:
liba { int a() { return b(); } }
libb { int b()

I would like to comment that I appreciate the lack of this feature,
I once had a typo in a makefile variable which was reported to me by a user of
either an old gnu-ld or a proprietary linker which

Reviewing this bug (due to this weekend's new comment), I notice I never
answered the question about why PurifyPlus is using this indirect-link feature.
I spoke with the developer who did the original Linux

I also hit this and I must admit it is slightly confusing at first. We were
linking -lnss3 which works fine with GNU ld, but with GNU gold you suddenly get
lots of unresolved references to PR_ functions. If you know

I haven't tried your test case yet, but in general this is intended behaviour
for gold. The GNU linker goes to considerable effort to replicate the search
path used by the dynamic linker. This leads to issues of the

I should say: thanks for the bug report. I appreciate it.
gold is not intended to be a precise replacement for the GNU linker. The GNU
linker has too much history and is the result of too many odd decisions (many
