MATLAB: Is the ‘rtlibsrc.h’ file not included in the current path of the generated code in Real-Time Workshop Embedded Coder

Embedded Coderfileheaderpackngopathsimulink

The generated code for my model contains the following line:

 #include "rtlibsrc.h"

However, this file is not located in the same path as the generated code. When I compile the code outside of Real-Time Workshop Embedded Coder, I need to copy the file every time. I would like this file to be placed in the same path as the generated code.

The ability to automatically include the 'rtlibsrc.h' header file in the same path as the generated code is not available in Real-Time Workshop Embedded Coder.

To workaround this issue from R2006b onwards, please use the command 'packNGo' to pack all the generated files. Using this command will automatically pick the file 'rtlibsrc.h'.

For previous product releases, read below for any possible workarounds:

To work around this issue, manually copy $MATLABROOT\rtw\c\libsrc\rtlibsrc.h file to the same directory as the generated code, where $MATLABROOT is the MATLAB installation directory on your machine which can be obtained by typing

matlabroot

at the MATLAB Command prompt.

MATLAB: Is the ‘rtw_shared_utils.h’ file included in the code when I generate code for the model using Real-Time Workshop Embedded Coder 5.2 (R2008b)

The 'rtw_shared_utils.h' file is generated and included when a shared utilities directory is created during the Real-Time Workshop build process. The shared utilities directory is created when the model being built contains Model blocks, or when the 'Utility Function Generation' option has been explicitly set to 'Shared Location'. This option is available on the 'Interface' pane in the Configuration Parameters window.

If generated, the 'rtw_shared_utils.h' file is located in the following directory:

 slprj/target/_sharedutils

For more information on Shared Utility Generation, refer to the documentation link below.

MATLAB: Do I receive an error when I manually compile code generated by Real-Time Workshop Embedded Coder 4.2 (R14SP2)

This bug has been fixed in Release 14 Service Pack 3 (R14SP3). For previous product releases, read below for any possible workarounds:

The documentation of Real-Time Workshop Embedded Coder 4.2 (R14SP2) is missing information about setting macro definitions when manually compiling generated code.

In particular, for fixed-point-only code, use the macro definition "-DINTEGER_CODE=1" when compiling code manually.
