Why do I receive an error message about missing pre-compiled libraries when I build my model for Embedded Target for Motorola MPC555 2.0.5 (R2006b)?

My model contains blocks from the Signal Processing Blockset, like the Digital Filter block. When I try to build my model for the Embedded Target for Motorola MPC555 I get the following error message and the build process aborts:

 ??? Error using ==> rtw_c.p>locMissingPrecompMsg

 There are pre-compiled libraries missing from the TargetPreCompLibLocation:

 C:\Program Files\MATLAB\R2006b\toolbox\rtw\targets\mpc555dk\drivers\lib\DIAB

 missing libraries:

 C:\Program Files\MATLAB\R2006b\toolbox\rtw\targets\mpc555dk\drivers\lib\DIAB\dsp_rt.a

The Signal Processing Blockset is configured to use a pre-compiled library that contains the functionality for all blocks in this blockset.

The pre-compiled library is target dependent and for the Embedded Target for Motorola MPC555 2.0.5 (R2006b), there is no library shipped with the product.

You can easily create the library once and then use it with different models. Open the model you want to build for MPC555. execute the following commands at MATLAB prompt:

buildSpec.rtwmakecfgDirs = {[matlabroot '\toolbox\dspblks\dspmex']};

rtw_precompile_libs(bdroot,buildSpec);

clear buildSpec

Note: Compiling and linking this library might take a couple of minutes, as there are a lot of functions included in the library.
