Introduction

Camel is a generic Windows^� / Linux CPU detection class which can display details about the hardware installed within the computer. It can display items such as the CPU manufacturer, CPU model and name, clock speed and other hardware details.

What Do I Get With This?

Well a complete CPU identification and capabilities class. Also there is a complete Windows version detection algorithm included in the demo source. The demo (including pre-compiled binary) provides a replacement for WCPUID and similar applications and as the binary is < 150 kb, it is nice and small.

How Can I Use It?

1. E-Mail me for permission to use/include (always given). I just want to know what purpose it is being used for. It is provided completely for "Non-Commercial Usage."
2. Include the files in your C++ project.
3. Compile!
4. Play!

Other notes:

The 2nd generation CPU speed test is "loosely" based on code from Pavlos Touboulidis. It is far enough removed to be no-longer copyright to him. I think. Anyway this is the obligatory mention.

Known Bugs And Problems:

CAM_00000001: Last Tree Node Fails To Display '+' Icon Properly.
CAM_00000002: CPU Speed Detection Results With +/- 10MHz Deviation. (FIXED: Version 1.2)
CAM_00000003: Fails To Detect APIC ID Properly With < Intel P4 Processors.

NOTE:

Some of the functionality is missing. Some of the menu items do not yet work nor some of the benchmarks. None of these missing features affect the CPU identification code! I apologize and will implement these in time. Or you can.....

Did "New Win32 App" (NOT console) and added all files to the respective folders ("Header Files", "Source Files", "Resource Files"). Then changed the "C Code generation" option: for Debug, set it to "Debug Multithreaded DLL"; for Release, set it to "Multithreaded DLL". Saved the project and hit "Rebuild All" with the default configuration, which is Debug; everything works and I end up with an executable that can be run without any problems. If I now quit MSVC, restart it, reload my newly created project and hit "Rebuild All", everything compiles but the linker complains (the error code is LNK2001) that it cannot find "WinMain@16". What the hell? I have made ZERO changes to the source files or the project files! Any hints are more than welcome. Thanks and best regards.

I add a reference to the DLL and I can declare a new variable with the type of CPUInfo, but it has no methods, only a few array methods...
