[Hyperic-hq-discuss] amd64 lib appears to be missing in distributable and unable to compile

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

I'm trying to access this library from my C/C++ codebase and have been unsuccessful so far.

Environment:
Visual Studio 2008 Professional
Windows 7 x64

1. I see `unresolved external symbols` while compiling with my project [1]. I will take a guess at the issue - the following files are included in the package:

sigar-amd64-winnt.dll
sigar-x86-winnt.dll
sigar-x86-winnt.lib

Shouldn't there be a `sigar-amd64-winnt.lib`?

2. I tried to build from the source. I am stuck with the errors listed in [2]. I see the declarations and use of those 2 functions in the codebase, but I do not see their implementations!

3. I tried building the project with Ant. I have no experience with Java or Ant, so please forgive me if I'm doing something very stupid here. I see the error in [3].
