linking SDL in Visual C++ 2005
Author
Hello, I just download Visual C++ 2005 Express Edition Beta. I'm not sure how to setup the linker for SDL and OpenGL. Anyone have experiance with this product?
In the older versions of visual studio (specifically VS.NET 2003) you would do this.
Now you can include SDL specific headers and call on them without getting link errors.
g/l
Click: Tools->OptionsSelect: Projects->VC++ DirectoriesAdd an entry for the SDL installation location (add for src, lib, header dirs etc..)Now after you create your project:Right click your project icon (after you open it in the right hand scrollable box) and select properties.Select the tab called "Librarian" or "Linker" and add an entry for your specific SDL dll file (usualy the dll name + ".lib") in the "Additional Dependancies" box.Now you can include SDL specific headers and call on them without getting link errors.

Now I'm getting:
main.obj : error LNK2005: _SDL_main already defined in game.obj
LINK : fatal error LNK1104: cannot open file 'uuid.lib'
main.obj : error LNK2005: _SDL_main already defined in game.obj
LINK : fatal error LNK1104: cannot open file 'uuid.lib'
Quote:main.obj : error LNK2005: _SDL_main already defined in game.obj
LINK : fatal error LNK1104: cannot open file 'uuid.lib'
LINK : fatal error LNK1104: cannot open file 'uuid.lib'
This means your compiler cant find/open uuid.lib.
Already defined means you don't have your files correctly setup and its getting redefined or something. Most likely its defined in game.cpp or whatever object that points to.
Guys, it's Beta. I had the same issues. I think SDL just doesn't work under VC8 yet. But in the future it'll be great. Like You can download custom templates and packs, like Dev-C++, but under the wide spread usability of VC. I only got VC7 becasue SDL_gfx had problems with Mingw and ahted it at first becasue I was hooked on DevPaks.
1. Download SDL 1.2.8 and extract it to a location for it to stay in. (C:\Program Files\SDL 1.2.8).
2. Since VC++ is still beta, you are not able to set directories yet. Instead, you must include the header file from the complete path:
4. Now go to "Project->Properties", "Linker->Input", and type in "uuid.lib" in the field that says "Ignore Specific Library".
5. Copy the SDL.DLL into your Debug/Release folders so it can be found when you run it. Everything should work fine now. Here's my code that I made for this test:
If anyone needs any help with what's been gone over feel free to ask [wink]. Good luck!

how'd u figure out that uuid.lib thing, the rest seems obvious.
edit: nvrnmd, in errors. When I was trying, I tried to do it the same way they say to do the Platform SDK

Visual C++ 2005 Beta 2 works just fine with setting directories up, its under Tools | Options...
and then the Projects and Solutions item on the left, VC++ Directories, as for linking you just need to goto project options, the linker, then input, and add SDL.lib and SDLmain.lib to the additional dependies box.

The OP and I are using the express ediitons [wink] I checked back here to post this quote for anyone else using the express edition on how to fix this:
Quote:Note: For Beta 2, you cannot set the Visual C++ Directories in the Options dialog of Visual C++ Express Edition. To work around this issue, you can update the Visual C++ Directories by modifying the VCProjectEngine.dll.express.config file located in the \vc\vcpackages subdirectory of the Visual C++ Express Edition install location. Please make sure that you also delete the file "vccomponents.dat" located in the "%USERPROFILE%\Local Settings\Application Data\Microsoft\VCExpress\8.0" if it exists before restarting Visual C++ Express Edition.

I did that VCProjectEngine.dll.express.config with SDL and it didn't seem to work...
