[zeromq-dev] Implementing zeromq security

[Riskybiz]

Thanks for the suggestions on how to build zeromq-4.0.4 with libsodium curve
security on Windows using the Visual Studio 2013 solution file.  

 

Getting warmer but there are still some issues...

 

I've made this modification;

 

builds/msvc/platform.hpp  added: #define HAVE_LIBSODIUM 1

 

And also set the added these configuration options in the Visual Studio 2013
zeromq solution for the libzmq project;

 

Set to 'Release' mode.

 

C/C++ -> General-> Additional Include Directories ->
C:\libsodium\src\libsodium\include

 

Linker -> General -> Additional Library Directories ->
C:\libsodium\bin\Win32\Release\v120\static  N.B. Also tried the \dynamic
folder but without luck.

 

Linker -> Input -> AdditionalDependencies -> libsodium.lib

 

The zeromq build is now looking for the libsodium files but gives the build
errors:

 

Error      4              error LNK1120: 3 unresolved externals
C:\zeromq-4.0.4\bin\Win32\libzmq.dll   libzmq

__imp__crypto_box_keypair
C:\zeromq-4.0.4\builds\msvc\libzmq\zmq_utils.obj               libzmq

 

 

I'm not really sure of which build options to set there is the choice of:
Debug, Release, Static Debug, Static Release, WithOpenPGM in the zeromq
build and then the dynamic, static or ltcg folders to link against in the
libsodium structure.  I've tried various options which seem sensible but am
really just pressing the buttons without understanding the implications of
the differences!

 

Anyone have any further suggestions?

 

Thanks,

 

Riskybiz.

 

P.S. I've also considered the suggested options at
http://lists.zeromq.org/pipermail/zeromq-dev/2014-November/027804.html but
am unable to find any project or solution configuration setting relating to;

 

(1) Properties->Configuration Properties->ZMQ Options->sodium->Enable

Sodium value to 'No'

(2) Properties->Configuration Properties->Local

Dependencies->libsodium->Linkage to 'Not Linked'
