Strange errors when compiling using mex

Hi,

I'm compiling with mex and I'm getting a few strange errors. I'm sure that there aren’t any errors in my cpp code (when opening the code in Visual Studio for example, I get no errors) so I really don't understand what's wrong with my code.

I'm compiling using the following line:

mex mexDenseSIFT.cpp Matrix.cpp Vector.cpp

and I'm getting the following errors (those are only the first few errors):

Error C:\FACERE~1\SIFTFL~1\MEXDEN~1\mexDenseSIFT.cpp: C:\FACERE~1\SIFTFL~1\MEXDEN~1\project.h: 8  syntax error; found `<' expecting `;' 
Error C:\FACERE~1\SIFTFL~1\MEXDEN~1\mexDenseSIFT.cpp: C:\FACERE~1\SIFTFL~1\MEXDEN~1\project.h: 8  skipping `<' 
Error C:\FACERE~1\SIFTFL~1\MEXDEN~1\mexDenseSIFT.cpp: C:\FACERE~1\SIFTFL~1\MEXDEN~1\project.h: 8  syntax error; found `T' expecting `;' 
Error C:\FACERE~1\SIFTFL~1\MEXDEN~1\mexDenseSIFT.cpp: C:\FACERE~1\SIFTFL~1\MEXDEN~1\project.h: 8  syntax error; found `>' expecting `;' 
Error C:\FACERE~1\SIFTFL~1\MEXDEN~1\mexDenseSIFT.cpp: C:\FACERE~1\SIFTFL~1\MEXDEN~1\project.h: 8  skipping `>' 
Error C:\FACERE~1\SIFTFL~1\MEXDEN~1\mexDenseSIFT.cpp: C:\FACERE~1\SIFTFL~1\MEXDEN~1\project.h: 9  syntax error; found `*' expecting `)' 
Error C:\FACERE~1\SIFTFL~1\MEXDEN~1\mexDenseSIFT.cpp: C:\FACERE~1\SIFTFL~1\MEXDEN~1\project.h: 9  skipping `*' `pBuffer'

Here is the file project.h:

#pragma once
#include "stdio.h"

// if the files are compiled in linux or mac os then uncomment the following line, otherwise comment it if you compile using visual studio in windows
 //#define _LINUX_MAC
#define _OPENCV

template  <class T>
void _Release1DBuffer(T* pBuffer)
{
    if(pBuffer!=NULL)
        delete []pBuffer;
    pBuffer=NULL;
}

template <class T>
void _Rlease2DBuffer(T** pBuffer,size_t nElements)
{
    for(size_t i=0;i<nElements;i++)
        delete [](pBuffer[i]);
    delete []pBuffer;
    pBuffer=NULL;
}

#define _MATLAB

#ifdef _MATLAB
#include "mex.h"
#endif

#ifdef _LINUX_MAC

template <class T1,class T2>
T1 __min(T1 a, T2 b)
{
  return (a>b)?b:a;
}

template <class T1,class T2>
T1 __max(T1 a, T2 b)
{
  return (a<b)?b:a;
}

#endif

Now, if I'm not missing anything, I can't see no problem with project.h. Moreover, the first few errors (which I quoted above) relate to line 8, which is:

template  <class T>

And I really can't see any error here.

Can someone please tell me what am I missing here?

Thanks!

Gil.

Which compiler are you using?

[Gil]

Hi, I'm using the following compiler:

Lcc-win32 C 2.4.1

Location: C:\PROGRA~2\MATLAB\R2008B~1\sys\lcc

Thanks!

Gil.

When you have MSVC installed on your computer, it would be a good idea to use it to compile MEX files also.

lcc is a C compiler which cannot be used to compile C++.

[Jan]

Exactly.
