The libsvm license ("the modified BSD license") is compatible with many free software licenses such as GPL. Hence, it is very easy to use libsvm in your software. Please check the COPYRIGHT file in detail. Basically you need to

1. Clearly indicate that LIBSVM is used.
2. Retain the LIBSVM COPYRIGHT file in your software.

[Go Top]

Yes, see libsvm tools

[Go Top]

This usually happens if you compile the code on one machine and run it on another which has incompatible libraries. Try to recompile the program on that machine or use static linking.

[Go Top]

Build it as a project by choosing "Win32 Project." On the other hand, for "svm-train" and "svm-predict" you want to choose "Win32 Console Project." After libsvm 2.5, you can also use the file Makefile.win. See details in README.

If you are not using Makefile.win and see the following link error

LIBCMTD.lib(wwincrt0.obj) : error LNK2001: unresolved external symbol
_wWinMain@16

[Go Top]

You need to open a command window and type svmtrain.exe to see all options. Some examples are in README file.

[Go Top]

"." means every 1,000 iterations (or every #data iterations is your #data is less than 1,000). "*" means that after iterations of using a smaller shrunk problem, we reset to use the whole set. See the implementation document for details.

[Go Top]

Very likely the program consumes too much memory than what the operating system can provide. Try a smaller data and see if the program still crashes.

[Go Top]

The easiest way is to use Makefile.win. See details in README. Alternatively, you can use Visual C++. Here is the example using Visual Studio .Net 2008:

1. Create a Win32 empty DLL project and set (in Project->$Project_Name Properties...->Configuration) to "Release." About how to create a new dynamic link library, please refer to http://msdn2.microsoft.com/en-us/library/ms235636(VS.80).aspx
2. Add svm.cpp, svm.h to your project.
3. Add __WIN32__ and _CRT_SECURE_NO_DEPRECATE to Preprocessor definitions (in Project->$Project_Name Properties...->C/C++->Preprocessor)
4. Set Create/Use Precompiled Header to Not Using Precompiled Headers (in Project->$Project_Name Properties...->C/C++->Precompiled Headers)
5. Set the path for the Modulation Definition File svm.def (in Project->$Project_Name Properties...->Linker->input
6. Build the DLL.
7. Rename the dll file to libsvm.dll and move it to the correct path.
