Octave on MSVC is essentially best effort and no work has been done on it since version 3.6.4. This bug report stands as good documentation of what to update to get this problem resolved, but nothing needs to be fixed in Octave itself.

I left out one piece of info. Sorry about that!

The math .h file is in
C:\Software\Octave-3.6.4\include

Top of file is:

*

  • This file is part of msvcmath library.
  • Author: Michael Goffioul

*/
#ifndef _MSVCMATHLIB_H_
#define _MSVCMATHLIB_H_

#ifndef _MSC_VER
# error "this header can only be used with Visual C++ compiler"
#endif

/* Make sure math constants are defined */
#ifndef _USE_MATH_DEFINES
# define _USE_MATH_DEFINES
#endif

math.h isn't an Octave file.

What do we need to change in Octave?

This applies to the Ocatve Version configured for WIndows install -- Microsoft Visual Studio 2010 version

The Dynamically Linked Function example Oct-File example in the manual at page 669 (685 of PDF) will not compile.

The compiler indicates that the mkoctfile compiler is not available -- actually it is a broken link to the Microsoft Visual Studio C compiler.

The following is a simple change that will allow compiling an oct file in Windows 7 and Windows Vista 64

Line 74 of math.h needs to be changed to compile if a 32 bit compiler is used -- like the C Express compilers.

Note that the only change is to add "(x86)" to line 74 as indicated.

/* Include VC++ original math.h */
#include <c:/Program Files (x86)/Microsoft Visual Studio 10.0/VC/include/math.h>

Using this batch file from a command prompt in the home directory appears to start Octane 3.6 correctly. This assumes that the Microsoft Visual Studio Express 2010 C++ compiler is installed.

call vcvarsall.bat x86
