//代码就是Clanlib说明里的自带代码
#include <ClanLib/core.h>
#include <ClanLib/application.h>

{
public:
virtual int main(int argc, char **argv)
{
CL_SetupCore setup_init;
// Insert game code here

}
} app;
编译出现以下错误，我实在不知道该怎么解决了，请高人指点。

应该是连接Clanlib库的问题
我编译使用Clanlib库的步骤如下
一、下载ClanLib-0.8.1,编译ClanLib-0.8.1需要的扩展库
libogg-1.1.3.zip
libvorbis-1.2.0.zip
SDL-devel-1.2.13-VC6.zip
。。。。。。。。。等等
二、运行ClanLib-0.8.1目录下的configure.dsw工程编译配置文件，编译完成后选择生成的库目录。
我选择的是C:\Program Files\Clanlib\include C:\Program Files\Clanlib\lib目录。
三、解压libogg等库，放在配置的目录中。
四、运行ClanLib.dsw编译Clanlib库，所有库我都编译了，无论是Debug还是Release版本。
五、在VC6.0中引入了include和lib，然后就直接新建工程测试Clanlib程序了，可一运行就一大堆错误。
也按照说明进行以下配置
Select the 'C/C++' tab, and then Category 'Code Generation'
5a. For Release version, change the 'Use run-time library' to Multithreaded.
5b. For Debug version, change the 'Use run-time library' to Debug Multithreaded.

这是怎么会回事呢？Clanlib库的英文使用说明如下，我是否是少了点什么?

Readme file for ClanLib 0.8.x under Win32
---------------------------------------------------------------------------
This readme will guide you with installing, compiling ClanLib and creating
your first ClanLib application.
If you have downloaded the binaries, you can skip section 3 and 4.
1. Getting started
2. Preparing installation
3. Configuring ClanLib
4. Compiling ClanLib
5. Testing ClanLib
6. Creating applications with ClanLib
7. Creating a workspace for your application
8. Problems ?
1. Getting started
---------------------------------------------------------------------------
Microsoft Developer Studio 7.x or 8.x is the recommended versions
to use with ClanLib. Visual Studio Express will also work, but it requires
a bit more manual configuration for each ClanLib project.
Microsoft Developer Studio 6.0 might also work, but we don't provide
precompiled binaries for external libraries for that.
Go to http://clanlib.org/download.html and download the precompiled binaries,
at least libjpeg and libpng multithreaded libraries. If you need more
functionality in ClanLib, you can download those other libraries you need.
Install these libraries in a directory - remember which one, because you
need to enter that information in the next section.
If you are using VC6, You MUST install service pack 5 from
http://msdn.microsoft.com/vstudio/downloads/updates/sp/vs6/sp5/
It is also recommended to install latest Microsoft Platform SDK, which
will give you a much newer set of include files and libraries, making it
possible to use things Microsoft invented since 1998. If you are using
VS.Net Express, then you will HAVE to do this.
The Microsoft Platform SDK is available at:
http://www.microsoft.com/msdownload/platformsdk/sdkupdate/
Windows builds of ClanLib use DirectX's DirectInput8 for input, so you'll
also need to install a recent version (8+) of the DirectX SDK.
DirectX SDK Downloads

2. Preparing installation
---------------------------------------------------------------------------
The first step in using ClanLib under Windows is to setup a sane build
environment. This involves two things:
1. ClanLib must be able to locate the libraries it uses.
2. ClanLib must know where to install itself.
My personal build environment is setup as follows using "c:\My Documents"
as base path. (You don't need to follow the same scheme, put your libraries
where it fits you).
"c:\My Documents\lib" contains all .lib files that didn't come along with
msvc++ and that are needed by ClanLib.
"c:\My Documents\include" contains all include files needed by the libs.
Here is how it looks like after I've installed Zlib:
c:\My Documents\lib\zlib.lib
c:\My Documents\include\zlib.h
c:\My Documents\include\zconf.h
You must configure Visual C++ so it knows where to find the include and
library files. This is done through the Tools -> Options -> Projects
-> VC++ Directories. Fill in the include directory
("c:\My Documents\include") under the Include Files listbox,
and the library directory ("c:\My Documents\lib") under the Library Files
listbox.
IMPORTANT: Put the new include and library paths on the TOP of the lists
(to avoid it using dx3 for instance) UNLESS you are using VS.Net 2005.
In that case, make sure the PlatformSDK include folder is at the top of
the list.
3. Configuring ClanLib
---------------------------------------------------------------------------
A freshly downloaded ClanLib source package will include a workspace/solution
and project for either MSVC6 (configure.dsw), or Visual Studio .NET 2005
(configure-vs80.sln). This is a configuration tool that
will generate the real ClanLib workspace and project files. If you are using
Visual Studio .NET below 2005, use the configure.dsw file and answer yes
to the conversion.
You have to compile and run this wizard and answer its questions carefully.
Incorrect information will give you problems during the compilation.
After you've compiled the app, just run it from inside of the compiler.
When the configure wizard asks me where to install the header and library
files, I specify those paths from section 2 (C:\My Documents\include and
C:\My Documents\lib).
When this is done, open the ClanLib.dsw file if you are using Developer
Studio 6, or the ClanLib.sln file if you are using .NET version. Answer
Yes to convert the file to your MSVC version if prompted.
4. Compiling ClanLib
---------------------------------------------------------------------------
After loading the ClanLib workspace, the project view will show many
different projects; clanApp, clanCore, clanDisplay etc...
Start with making clanCore the active project, if its not active already.
You do this by right-clicking it, and select 'Set as Active Project'.
Select Debug or Release in the toolbar. If you can't find this option
anywhere, right click on the toolbar, and make sure Build is selected,
and deselect the Build Minibar. Press F7 to compile the active project.
You need to compile at least these projects:
- ClanApp
- ClanCore
- ClanDisplay
- ClanGL
Optionally, you can compile the others if you need them. Batch Build is
handy here.
You'll get some warnings for the different projects, similar to:
ddraw.lib(DDRAW.dll) : warning LNK4006: __NULL_IMPORT_DESCRIPTOR already
defined in winmm.lib(WINMM.dll); second definition ignored
GLU32.lib(GLU32.dll) : warning LNK4006: __NULL_IMPORT_DESCRIPTOR already
defined in OpenGL32.lib(OPENGL32.dll); second definition ignored
LINK : warning LNK4098: defaultlib "LIBCMT" conflicts with use of other
libs; use /NODEFAULTLIB:library
Ignore these warnings, they are not important.
For each library in ClanLib, we produce two .lib files, eg clanCore.lib and
clanCored.lib. The first one is for release versions of your game, and the
second is for debug versions.
The debug version includes debugging information in the library itself (so
if the lib crashes, you can see where in the source code it crashed).
After a successful compilation of ClanLib, it will automatically run a batch
file that will install all headers and lib files in the path you specified
in the wizard. In my case, that is "c:\My Documents\lib" and
"c:\My Documents\include". So the following files will be added:
c:\My Documents\lib\clanCore.lib (release lib)
c:\My Documents\lib\clanCored.lib (debug lib)
c:\My Documents\lib\clanGL.lib
c:\My Documents\lib\clanGLd.lib
c:\My Documents\include\ClanLib\core.h
c:\My Documents\include\ClanLib\gl.h
...
5. Testing ClanLib
---------------------------------------------------------------------------
To have a look at some examples of various parts of ClanLib, open the
Examples.dsw/.sln file in your ClanLib root directory. This was created after
you ran the Configure application.
Select any example, and compile it. You'll find examples covering most
parts of the ClanLib API.
Once you're done and ready for some coding, proceed to next section.
6. Creating applications with ClanLib
---------------------------------------------------------------------------
Note that MSVC will know what .lib file to link into your application, based
upon the ClanLib headers you include in your application.
Example:
If you include <ClanLib/core.h> then depending on whether you are
building release or debug binaries the clanCore.lib or clanCored.lib
library will be automatically linked into your executable.
If you use Visual Studio Express, you need to include some additional libraries,
user32.lib gdi32.lib and ole32.lib. Put them in the Additional Dependencies
under the Linker setting in your project settings.
7. Creating a workspace for your application
---------------------------------------------------------------------------
1. Select File->New...
2. Select Projects->Win32 Application, and specify where you want it located.
3. Select "An empty project", and press OK till you're finished with the wizard.
4. Select Project->Settings...
Notice there are several configurations in which you can modify settings.
Normally, these are 'Win32 Debug' and 'Win32 Release'. You switch between
these in the 'Settings for:' droplist.
In section 5 and 6 below, you need to modify both these settings
(sections a for release setting, and sections b for debug settings).
5. Select the 'C/C++' tab, and then Category 'Code Generation'
5a. For Release version, change the 'Use run-time library' to Multithreaded.
5b. For Debug version, change the 'Use run-time library' to Debug Multithreaded.
6. Select Project->Add To Project->New...
7. Select C++ Source File, and enter a name for the file, for example 'app.cpp'
8. Enter a skeleton for your code:
#include <ClanLib/core.h>
#include <ClanLib/application.h>
#include <ClanLib/display.h>
#include <ClanLib/gl.h>
class MyApp : public CL_ClanApplication
{
public:
virtual int main(int argc, char **argv)
{
// Create a console window for text-output if not available
// Use printf or cout to display some text in your program
CL_ConsoleWindow console("Console");
console.redirect_stdio();
try
{
// Initialize ClanLib base components
CL_SetupCore setup_core;
// Initialize the ClanLib display component
CL_SetupDisplay setup_display;
// Initialize the ClanLib GL component
CL_SetupGL setup_gl;
// Create a display window
CL_DisplayWindow window("ClanLib application", 640, 480);
// Run until someone presses escape
while (!CL_Keyboard::get_keycode(CL_KEY_ESCAPE))
{
// Clear the display in a dark blue nuance
// The four arguments are red, green, blue and alpha (defaults to 255)
// All color nuances in ClanLib are measured in the interval 0->255
CL_Display::clear(CL_Color(0, 0, 50));
// Flip the display (using a double-buffer),
// showing on the screen what we have drawed
// since last call to flip()
CL_Display::flip();
// This call updates input and performs other "housekeeping"
// Call this each frame
// Also, gives the CPU a rest for 10 milliseconds to catch up
CL_System::keep_alive(10);
}
}
// Catch any errors from ClanLib
catch (CL_Error err)
{
// Display the error message
std::cout << err.message.c_str() << std::endl;
}
// Display console close message and wait for a key
console.display_close_message();
return 0;
}
} app;
