The professional versions of VS2010 and VS2012 both worked fine. Make sure you have a copy of Visual Studio 2010 or 2012.I got my copy of octave-3.6.2-vs2010-setup.exe at the SourceForge download page and installed with the default options. Make sure you install the Visual Studio version of Octave.Compilation of C source code requires a C compiler, and we will use the compiler in Microsoft’s Visual Studio. mex files are available, we will have to put them somewhere Octave will know to look for them in. mex file built for use in Matlab, for example, will not work Octave.Īt this point it should be clear that to invoke LIBSVM from Octave, we will have to compile C source code to. x86 or 圆4), and whether they are intended for use by Matlab or Octave. mex files are highly dependent on the operating system, the processor architecture of Matlab/Octave (e.g. mex file (or files), which Matlab and Octave know how to deal with. Neither Matlab nor Octave can invoke C code directly. LIBSVM itself was compiled from C source code, available elsewhere in the LIBSVM folder structure. This folder includes 5 C source files and 1 header file that together define an interface for Matlab and Octave to invoke LIBSVM. The LIBSVM distribution includes a matlab subfolder.
There are instructions on building ‘x’, ‘x’, ‘x’, and ‘x’, but those didn’t work for me right out of the box, and it wasn’t clear what to do with the. The README file in the LIBSVM matlab subfolder adds that prebuilt binaries are included only for 64-bit Matlab on Windows. Your mileage may vary.Īccording to the LIBSVM FAQ, Octave support has been available since version 2.86 (of LIBSVM), and all you have to do was type make inside Octave. I did this with an 圆4 build of Windows 8, Octave 3.6.2 圆4, and LIBSVM 3.13.
This post will help you get to the point where you can invoke LIBSVM commands from Octave, on Windows.
