Re: Compiling NetSNMP for x64 Windows

Hi Dave,
There is another issue with the “openssl” in Net-snmp windows 5.6.1 and 
5.5.1 builds I thought I should bring it up to your attention: It seems 
Net-snmp 5.6.1 (and 5.5.1) windows build depend on the Openssl 
distribution from slproweb.

However in net-snmp readme.win32 it says:

===============================================================
OpenSSL is required to support the encryption capabilities in SNMPv3
(or SHA authentication). The win32 version of OpenSSL can be built
from the sources or you can download a pre-compiled version.

Building from source: … (instructions skipped...)
===============================================================


With NETSNMP 5.5 and older releases we can either use slproweb's openssl 
or our own openssl build.

NetSNMP 5.6.1 and 5.5.1 require libeay32MT.lib and libeay32MD.lib in 
their build processes. However it seems these files are only available 
from the openssl1.0.0x binary packages distributed by "slproweb". If we 
build Openssl 1.0.x from source, it does NOT produce those files, but 
only “libeay32.lib” as with its older openssl 0.9.x releases. In the 
Openssl's nmake file from its source release, it uses “/MD” compiler 
option if you build “DLL”; If you build a “static” library then it uses 
“MT” compiler option. It seems to me Slproweb made their changes without 
giving any real good reasons/explanations. However this does create a 
new problem for our net-snmp Windows build. That is --by using 
libeay32MT etc. we did make Net-snmp 5.6.1 (and 5.5.1) windows build 
DEPEND on the Openssl distribution from slproweb. In our case we don't 
use slproweb's openssl build so I actually have to change NOT to use 
libeay32MT.lib and libeay32MD.lib, etc.

At least I think the readme.win32 needs to be updated.

BR,
