MATLAB: Are Ada S-functions supported on Linux64 and Windows64 in Simulink 6.5 (R2006b)

64adalinuxsimulinksupportedwindows

I would like to know if Ada S-functions are supported on Linux64 and Windows64 in Simulink 6.5 (R2006b).

This bug has been fixed in Release 2007b (R2007b). For previous product releases, read below for any possible workarounds:

Ada S-Functions are not supported on GLNXA64 and WIN64 platforms. Ada S-Functions are only supported on WIN32, GLNX86 and SOL2 platforms in MATLAB 7.2 (R2006a) and MATLAB 7.3 (R2006b)

MATLAB: Do I receive an error about gcc version when executing a MEX-file or an executable generated by MATLAB Compiler on Linux

This error may occur when you use MATLAB or MATLAB Compiler in combination with GNU gcc 3.3.x, with gcc 3.2.3 that is distributed by Red Hat, or with another unsupported version of gcc. For the list of supported compilers, consult the following document:

http://www.mathworks.com/support/compilers/current_release/

See the related solution to compile and install a fully compatible GNU gcc. While installing the supported version of gcc is strongly recommended, some of our customers have reported the following workarounds are successful. These workarounds have not been tested and are not supported by MathWorks.

Workaround 1:

Before starting MATLAB (if executing a MEX-file) or before executing a file generated by MATLAB Compiler, set the LD_PRELOAD environment variable to /lib/libgcc_s.so.1

For bash users:

 export LD_PRELOAD=/lib/libgcc_s.so.1

For csh users:

 setenv LD_PRELOAD /lib/libgcc_s.so.1

Workaround 2:

Another workaround is to replace some library files in the MATLAB installation with the corresponding libraries from the version of GCC you are using. Be sure to create backup copies of any libraries you replace, since you may have errors in MATLAB after replacing the libraries. For example in MATLAB 7.1 (R14SP3) you could replace the following files:

libg2c.so.0.0.0 
libgcc_s.so.1 
libstdc++.so.5.0.3

and the symbolic links associated with these files with newer libraries from your gcc release. The files to be replaced are in the following directory:

$MATLABROOT/sys/os/$ARCH

(where $MATLABROOT is the MATLAB root directory on your machine, as returned by typing:

matlabroot

at the MATLAB command prompt and $ARCH is your architecture "glnx86" for 32-bit Linux and "glnxa64" for 64-bit Linux.)

MATLAB: How to add or remove specific S-function block ports in Simulink 6.5 (R2006b)

The ability to add or remove specific S-function block ports is not available in Simulink 6.5 (R2006b).

To work around this issue, you can put your S-function block inside a masked Subsystem block. This creates another hierarchical layer for your S-function block, such that it connects to the rest of the model through the Subsystem block's inports and outports. Within the context of that Subsystem, you can use a mask callback function to implement logic that allows the block to maintain its wiring. For example, use the:

1. ADD_LINE and DELETE_LINE functions to create and remove signal lines

2. SET_PARAM function to change the port number of a specific port
