[Qemu-devel] undefined symbol _nettle_cast5_set_key

[Programmingkid]

Noticed this bug after a 'git pull'. My repo is at commit 65603e2fc18b48e6e55a3dd693669413141694ec - 
tci: do not include exec/exec-all.h

I am building QEMU on Mac OS 10.6 with GCC 4.9.
Here is the full message:

What version of nettle are you compiling against? Obviously it's an
older version, but is it one that we need to work around at configure
time, or one that you should just update locally?

I'm not sure how to find the version of nettle. Would you have a simple program that could tell me this information?

On Fedora, it's:

# rpm -q nettle-devel
nettle-devel-3.2-1.fc23.x86_64
# pkg-config --modversion nettle
3.2

I don't use MacOS, so I have no clue how to query your package manager
about what version of a given package is installed, but the pkg-config
command might work.

$pkg-config --modversion nettle
3.2

Hope this helps.

I think in general if we can't build against a version of
a library dependency we should always disable the relevant
optional feature at compile time -- this just makes life easier
for users, since updating a library (or removing it) isn't always
possible.

I like that idea.

Absolutely, I'll be looking into this issue now I'm back from vacation.

So we already have compatibility code to allow us to build with older
versions of nettle that I've tested right back to nettle 2.4.

The "cast5_set_key" method is present in the nettle 3.2 version that
Programmingkid has installed. The nettle headers mangle the name
'cast5_set_key' into 'nettle_cast5_set_key', but I'm not sure where
the extra leading '_' is coming from in either _nettle_cast5_set_key
or _qcrypto_cipher_new. Presumably that is something specific to
Os-X linking.

So I don't think this is a question of incompatible older versions of
nettle. Rather than is some problem with linking going on here.


I'd like to see the output of 'configure' as well as the config.log
and config-host.mak files that it generates when showing this error.

Also I'd like the output of 'make V=1' so we see the full linker
command line, not just the summary.

Regards,
Daniel

I think that's just that the osx linker doesn't bother to unmangle
the names when it prints them, and it has the common convention of
prefixing C function names with an '_' for the symbol.

Ok, that shows we've detected your nettle 3.2 install. The
support for 'kdf' also shows we successfully compiled and
linked against that. This is shows your 3.2 install of nettle
is present & correct which is good.

This is the link line where configure tested for the KDF function and it looks normal and

This linker line again looks basically sound. It is still passing the
correct -lnettle arg, and the -I and -L args to point to the nettle
3.2 installation.

Given that we found the "KDF" support in nettle, we know that it is
new enough to support the "nettle_cast5_set_key" function too so
we ought to link correctly.

The only thing that occurs to me is that we have a number of other
-L args present - eg -L/opt/local/lib.

I wonder if one of those  other search paths has a differnet version
of nettle installed in it, causing gcc to link to the wrong one.

Regards,
Daniel

I did a search and found libnettle.4.7.dylib in /opt/local/lib. I also found libnettle.6.2.dylib in /usr/local/Cellar/nettle/3.2/lib.

Ah ha, that sounds like it could well be the cause of the problems.

I'm not sure if there's a reason you have nettle in both /opt/local/lib
and /usr/local/Cellar/nettle/3.2/lib.  The -L/opt/local/lib arg appears
before the -L/usr/loca/Cellar/nettle/3.2/lib arg, so I expect that means
it will be picking up the older libnettle.4.7.dylib first :-(

Changing the order of the -L arg that QEMU uses is not exactly a
straightforward / practical thing todo. If its possible for you
to get rid of the older 4.7.dylib file i expect that would fix
the QEMU build, but not sure if that'll break something else on
your OS-X system.

I'm not really sure there's much we can do to detect this problem
in QEMU's configure script either. The config.log file seems to
show that at the time we probe for nettle & test linking with it,
we've not yet detected the later that uses -L/opt/local/lib.

Daniel

Maybe we can change things so that we only use the highest version of nettle detected. 

Nettle is a library that deals with cryptography which I don't need or use. Is there a way to turn off its inclusion into QEMU?

AFAIK, it is the linker that would have todo that, not something under
our direct control. We just tell the linker what directories to look
in and in your case you have different copies of the same lib in multiple
places and the linker picks the first that it finds.

Of course, you can always use the --disable-nettle flag to configure
or force use of gcrypt instead with --enable-gcrypt
