Relocate Code Generated from MATLAB Code to Another Development Environment
Once you generate code from your MATLAB® algorithm, you can relocate the code to another development environment,
such as a system or an integrated development environment (IDE) that does not include
MATLAB. You can package the files into a compressed file using the
packNGo function at the command line or the
Package option in the MATLAB
Coder™ app. Once you create the zip file, you can relocate and unpack the
compressed zip file using a standard zip utility.
Package the Code
This example shows how to package the executable generated from the Generate C Code from MATLAB Code example using the
packNGo function. You can also generate and package a
static library file or a dynamic library file. You cannot package a C-MEX file since
a MEX file requires MATLAB to run. For more information on
packNGo in RTW.BuildInfo Methods (MATLAB Coder).
The files needed to generate the executable are
GenerateSignalWithHighEnergyFFTCoeffs.m, and the
reconstructSignalTestbench_Main.c files from the Generate C Code from MATLAB Code example. Copy all these files into the
current working folder. To generate the executable, run the following commands in
the MATLAB command prompt:
cfg = coder.config('exe'); cfg.CustomSource = 'reconstructSignalTestbench_Main.c'; cfg.CustomInclude = ['"',pwd,'"']; codegen -config cfg -report reconstructSignalTestbench
If you are using Windows, you can see that
reconstructSignalTestbench.exe is generated in the current
folder. If you are using a Linux machine, the generated executable is
codegen function generates the dependency source code and
buildinfo.mat file in the
Package the code in a
.zip file using the
packNGo function creates a zip file,
reconstructSignalWithHighEnergyFFTCoeffs.zip in the current
working folder. In this example, you specify only the file name. Optionally, you can
specify additional packaging options. See Specify packNGo Options (MATLAB Coder).
.zip file contains the C code, header files,
.dll files, and the executable that needs to run on the
external environment. Relocate the
.zip file to the destination
development environment and unpack the file to run the executable.
Prebuilt Dynamic Library Files (.dll)
If you compare the contents of the
codegen\exe\reconstructSignalTestbench folder and the
reconstructSignalWithHighEnergyFFTCoeffs.zip folder, you
can see that there are additional
.dll files that appear in the
zip folder. These
.dll files are prebuilt dynamic library files
that are shipped with MATLAB. Executables generated from certain System objects require these
.dll files. The Generate C Code from MATLAB Code example uses
dsp.IFFT System objects whose
'FFTImplementation' is set to
the FFTW mode, the executables generated from these objects depend on the prebuilt
.dll files. To package code that runs on an environment with
no MATLAB installed, MATLAB
Coder packages these
.dll files in the zip folder. For a
list of all the System objects in DSP System Toolbox™ that require prebuilt
.dll files, see How To Run a Generated Executable Outside MATLAB.
To identify the prebuilt
.dll files your executable requires,
run the following command in the MATLAB command prompt.
files = getNonBuildFiles(buildInfo,'true','true');
For more details, see
getNonBuildFiles in Build Process Customization (MATLAB Coder).
