libsvm.cpp编译错误MATLAB

Question

我已经下载了libsvm for MATLAB从official site （我使用MATLAB，2010年b） 但每当我运行make文件，我得到：

>> make 
Error svm.cpp: 13 syntax error; found `<' expecting `;' 
Error svm.cpp: 13 skipping `<' 
Error svm.cpp: 13 syntax error; found `T' expecting `;'

Error svm.cpp: 16 too many errors 

    C:\MATLAB\R2010B\BIN\MEX.PL: Error: Compile of 'svm.cpp' failed. 

??? Error using ==> mex at 208 
Unable to complete successfully. 

Error in ==> make at 5 
mex -O -c svm.cpp 

即使像执行每一条指令： MEX -O -​​c svm.cpp

我得到了同样的错误，我究竟做错了

PD

我已经验证编译器的问题：

>> mex -setup 
Please choose your compiler for building external interface (MEX) files: 

Would you like mex to locate installed compilers [y]/n? y 

Select a compiler: 
[1] Lcc-win32 C 2.4.1 in C:\MATLAB\R2010b\sys\lcc 

[0] None 

Compiler: 1 

Please verify your choices: 

Compiler: Lcc-win32 C 2.4.1 
Location: C:\MATLAB\R2010b\sys\lcc 

Are these correct [y]/n? y 

Trying to update options file: C:\AppData\Roaming\MathWorks\MATLAB\R2010b\mexopts.bat 
From template:    C:\MATLAB\R2010b\bin\win32\mexopts\lccopts.bat 

Done . . .

内置的编译器附带的Matlab是LCC：http://www.cs.virginia.edu/~lcc-win32/，这是一个C语言编译器，所以它不能编译CPP代码。看到这里：http://www.mathworks.com/support/tech-notes/1600/1605.html#C_compiling

你必须安装另一个编译器，并配置Matlab使用它，要么通过mex -setup，要么自己编辑mexopts.bat。
