Mex and compiler setting

How to set up mex compiler on a 64-bit Matlab using Visual Studio 2008 Professional

Go to http://www.mathworks.com/matlabcentral/fileexchange/loadFile.do?objectId=18508&objectType=file and copy the x64 mex option files under the MATLABROOT\bin\win64\mexopts.
Do a mex -setup. Let Matlab locate the installed compiler. Select "Microsoft Visual C++ 2008".
Use mex command to compile a simple file. You get the following error

  
C:\PROGRA~1\MATLAB\R2007B\BIN\MEX.PL:  
Error: Using options file: 
         C:\Users\deancool\AppData\Roaming\MathWorks\MATLAB\R2007b\mexopts.bat 
         You cannot use this file with the WIN64 architecture because it enables 
         a compiler for a different architecture. 
         Running mex -setup may resolve this problem.

Now locate your mexopts.bat file. Edit the following lines:
1. Line 17 (set PATH): add '\amd64' after set PATH=%VCINSTALLDIR%\BIN\
2. Line 19 (set LIB): add '\amd64' after set LIB=%VCINSTALLDIR%\ATLMFC\LIB and %VCINSTALLDIR%\LIB. Add '\x64' after C:\Program Files\Microsoft SDKs\Windows\v6.0A\lib
3. Line 20: set MW_TARGET_ARCH=win64
4. Line 34: set LIBLOC=%MATLAB%\extern\lib\win64\microsoft
5. Line 36: /MACHINE:X64

How to set up the C compiler from Visual Studio 2008 on a 64-bit Windows system

Go to control->system->environmental variables. Edit 'path' and add the following dir: C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin\amd64
Go to control->system->environmental variables. Edit 'LIB' and add the following dir: C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\lib\amd64

Or go to C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin\amd64 and run vcvarsamd64.bat

== How to compile cvOdesGenMod5.c

Windows

1. Enter COMKATROOT\CVODESserial-2.3.0-2005\sundials\cvodes\source. Run:

cl /c /I..\include /I..\..\shared\include *.c
lib /out:cvodes.lib *.obj

Copy cvodes.lib to the COMKATROOT\lib\win64 folder (change win64 according to your system) 2. Enter COMKATROOT\CVODESserial-2.3.0-2005\sundials\shared\source. Run:

cl /c /I..\include  *.c
lib /out:sundials.lib *.obj

Copy sundials.lib to the COMKATROOT\lib\win64 folder (change win64 according to your system) 3. Enter COMKATROOT\CVODESserial-2.3.0-2005\sundials\nvec_ser. Run

cl /c /I..\shared\include  *.c
lib /out:nvec_ser.lib *.obj

Copy nvec_ser.lib to the COMKATROOT\lib\win64 folder (change win64 according to your system) 4.
