Question about mex compilation on 64bit machine in Windoze

Jim Rockford — Mon, 24 Nov 2008 10:32:19 -0500

I have recently installed Matlab R2008b. I understand that there is
no default lcc compiler for 64 bit, and that a free compiler can be
used:

Microsoft Platform SDK for Windows Server 2003 R2

I have this SDK platform installed, but when I run "mex -setup" in
Matlab, I see absolutely zero [0] options for choices of compiler, so
Matlab simply does not recognize the existence of this installation.

What do I have to do to use the SDK platform to compile with mex? Why
doesn't Matlab recognize it? Is it a matter of setting an environment
variable?

Thanks,
Jim

That's not a compiler. It's a software development kit containing
mainly lib and include files. You may be interested in looking at
Visual Studio Express Editions or gcc products.

The last time I look, Express Edition doesn't seem to support 64-bits executable builder:

http://www.microsoft.com/downloads/details.aspx?FamilyId=727BCFB0-B575-47AB-9FD8-4EE067BB3A37&displaylang=en

Is there any additional package that should download separately to accomplish it?

You're right. But there exists some support for mexing on Win64:
http://www.mathworks.com/support/compilers/current_release/win64.html
Perhaps it's only 32-bit image; I have no access to such system to
verify it.

I know it's a software development kit, but apparently it's got
sufficient muscle to act as the compiler one would need for mex'ing
64bit applications in Matlab. I am simply responding to the
information from Mathworks support:

http://www.mathworks.com/support/solutions/data/1-36NJ5U.html?solution=3D1-=
36NJ5U

Note that there is also a link on that page addressing the problem I'm
having with mex -setup, but my manual path setting failed and I'm
curious as to why Matlab doesn't recognize my SDK installation by
default.

Jim,

Yes you need to have MSSdk environment variable defined.

The only reference to this in the documentation seems to be:
http://www.mathworks.com/access/helpdesk/help/techdoc/index.html?/access/helpdesk/help/techdoc/rn/f34-998197.html#f34-1011313
"The environment variable MSSdk must be defined. The value of this
environment variable is the path to the installation directory for Microsoft
Platform SDK for Windows Server 2003. This environment variable is not
commonly defined by the Microsoft Platform SDK installation program."

Hope that helps.

Jim,

I think there is some information missing from the solution you mentioned.
I am working with technical support to improve that solution.

Let us know if defininf MSSdk worked for you.

Thanks,
Gadi
