Re: Compiling NetSNMP for x64 Windows

Hi,
We have recently successfully built net-snmp5.6.1 and netsnmp 5.5.1
on windows x64 systems when working on our SNMP API products.

No special things need to be done. You just need to build net-snmp
in a x64 build environment. For example, if you use Microsoft platform
SDK 7,  you would do :

Click "Start->Microsoft Windows SDK v7.0->CMD shell"
setenv /x64 /release
and then use  build.pl  or build.bat like you do normally for 32-bit 
Windows.

For a "dynamic" build, if you use openssl, you need to get openssl build 
for
x64 windows from slproweb. You need to copy the 64-bit openssl lib version:
from:
C:\OpenSSL-1.0.0.c-Win64\lib\VC\libeay32MT.lib and
C:\OpenSSL-1.0.0.c-Win64\lib\VC\libeay32MD.lib

into

C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\lib\amd64,

Also copy the "openssl" header files folder as you would do for 32-bit 
builds.
After that the build should work.

For a  "static" build,  unless you add linking with "Gdi32.lib", the build
will fail  with link errors.  For a "static" build, NETSNMP-5.5 is 
linked with
Gdi32.lib but netsnmp-5.6.1 and 5.5.1 are NOT! This appears to be a bug.

If needed we can share our Windows Net-SNMP binary with the community.
We can post it on our website so anyone  can download it freely.

Hope this helps.
