link failure with LDFLAGS="-Wl,--as-needed"

[Robin H. Johnson]

The order of items being presented for linking needs to be fixed to work with -Wl,--as-needed.

Is there a patch to this? I get the same error on Solaris 10 Sparc 64bit machine.

[Sandy (sandeeptt)]

If I configure libmemcached with "--disable-sasl --disable-dtrace", I see a different error when compiling a product dependent on libmemcached.

"/opt/libmemcached-0.44/inst/include/libmemcached/server.h", line 54: undefined symbol: NI_MAXHOST
"/opt/libmemcached-0.44/inst/include/libmemcached/server.h", line 54: can not declare variably modified type at file scope

[Trond Norbye (trond-norbye)]

I'll try to get around to look at this bug this weekend...

[Sandy (sandeeptt)]

Sure. Thanks Trond. Is the missing symbol appeared because I disabled sasl while configuring? Or?

[Trond Norbye (trond-norbye)]

I pushed a fix for the compile problems on Solaris to https://code.launchpad.net/~trond-norbye/libmemcached/compile-fixes (they are unrelated to the original bug).

[Trond Norbye (trond-norbye)]

I tried to reproduce this on Debian with gcc 4.4.5, and it compiles without problems after:

./configure --enable-sasl --without-memcached LDFLAGS=-Wl,--as-needed

I guess that this has been fixed at some time.. Please reopen the bug if you're unable to compile libmemcached with --as-needed to the linker..

Hi!

No one has provided a patch.

Cheers,
