C++ API Now Supports 64-Bit Default

In Release R2007b, the MX_COMPAT_32_OFF variable allowed for 64-bit support. In this release, 64-bit is the default setting. If you still require explicit 32-bit execution, see Addressing mwArrays Above the 2 GB Limit for more information.

Support Added for Microsoft® Visual Studio 2008 Compiler

Support has been added for the compiler included with Microsoft Visual Studio 2008. See System Requirements in the MATLAB® Compiler User's Guide documentation for more details.

Replacement of mclmcr Header File

Starting with release R2008a, replace all occurrences of #include mclmcr.h with #include mclmcrrt.h.

If the library header created by MATLAB^® Compiler is included in the external code, neither of these files need to be included, since the library header includes the correct file

Run-time Libraries Required for Applications Built with Microsoft^® Visual Studio^® 2008 Compiler

If you distribute a MEX-file, an engine application, or a MAT-file application built with the Visual Studio^® 2008 compiler, you must provide the Visual C++^® run-time libraries. These files are required to run applications developed with Visual C++ on a computer that does not have Visual C++ 2008 installed. For information on locating the Microsoft^® Visual C++^® 2008 Redistributable Package (x86), containing vcredist_x86.exe and vcredist_x64.exe, consult your Microsoft^® documentation.

Large Array Support Now Default For C and C++ Code

In R2008a, the default definition of MX_COMPAT_32 has been removed, and large array support is now the default for both C and C++ code. This new default may, in some cases, cause compiler warnings and errors. You can define MX_COMPAT_32 in your mbuild step to return to the previously default behavior.

Code compiled with MX_COMPAT_32 is not 64-bit aware. In addition, MX_COMPAT_32 controls the behavior of some type definitions. For instance, when MX_COMPAT_32 is defined, mwSize and mwIndex are defined to ints. When MX_COMPAT_32 is not defined, mwSize and mwIndex are defined to size_t. This can lead to compiler warnings and errors with respect to signed and unsigned mismatches.

For information about expected behavior of this feature in R2007b, see Addressing MWArrays Above the 2 GB Limit.

This feature changes how the MWArray C++ Library functions are implemented. For more details, see Addressing mwArrays Above the 2 GB Limit in the MATLAB^® Compiler™ User's Guide documentation.

Support Dropped for Borland Compilers

Borland compilers are no longer supported as of this release.

MATLAB^® Component Runtime Renamed

The MATLAB Component Runtime has been renamed to the MATLAB Compiler Runtime.

MATLAB^® Application Deployment Web Example Guide Available

A new publication, the MATLAB Application Deployment Web Example Guide, is now available from the MATLAB® Compiler™, MATLAB® Builder™ NE, and MATLAB® Builder™ JA roadmap pages.

The guide provides full examples of common tasks performed by the MATLAB programmer, IT specialist, and others who play significant roles in deploying MATLAB applications to the Web.
