Hi,<div><br></div><div>My name is Alex Sicoe and I'm currently investigating RRDTool to decide if I can use it for my final year University project. I'm trying it out on Windows. I've followed the instructions at the website <a href="http://oss.oetiker.ch/rrdtool/download.en.html">http://oss.oetiker.ch/rrdtool/download.en.html</a> and downloaded the Binary distribution for windows. Then I've followed the instructions in the "WIN32-BUILD-TIPS" file. Everything ok until I reached step 4. When I build the solution containing the 2 projects <b>rrdlib</b> and <b>rrdtool</b> (with Microsoft C++ in Microsoft Studio 2008 - Professional Edition) it comes up with 3 errors in the rrdlib project and 1 error in the rrdtool project (See below).</div>
<div><div><br></div><div>Question 1: Is it necessary to build rrdtool on my machine? I saw that there are some bindings for Python for example. Do those bindings just work without the need to build the entire thing? Rephrasing this, if I install Python can I just import a .dll for the whole RRDTool that allows me to benefit the entire functionality without building from scratch?</div>
<div><br></div><div>Question 2: What do I need to do about these errors I get?</div></div><div><br></div><div><div>For the <b>rrdlib</b> project the build log shows:</div><div>----------------------------------------------------------------------------------------------------------------------------------------------------------------------------</div>

<div><br></div><div>I apologise for the very boring and noob questions. I hope somebody can help me out solve this problem as fast as possible, I need to start getting the feel for RRDTool because my project is starting in January!</div>
<div><br></div><div>Thank you,</div><div>Alex</div><div><br></div><div>P.S. I spent time searching through the forum and the mailing list archives but I couldn't find any similar issue from before. </div>
