Use the code generator packNGo option to generate code in one location. After code generation, collect the compiler command-line options, move the generated code to another location, and compile the generated code in combination with custom code.
For this example, you must have the gcc toolchain running on a Linux® platform. After verifying this platform, this example sets up the path, folders, and files.
When you rerun the example, to ease clean up of generated files, the work folders (code_generation_area_dir and build_area_dir) are separate from the source files (models_dir and hand_code_dir).
All locations of source file and folders use paths that are relative to the folder containing the example .M file.
if ismac % Code to run on Mac platform disp('Platform (Macintosh) not supported.') elseif ispc % Code to run on Windows platform disp('Platform (Windows) not supported.') elseif isunix
originalFolder = pwd; thisFilesFullName = mfilename( 'fullpath' ); thisFilesAbsolutePath = fileparts( thisFilesFullName ); modelsFolder = fullfile( thisFilesAbsolutePath, 'models_dir' ); codeGenerationRootFolder = ... fullfile( thisFilesAbsolutePath, 'code_generation_area_dir' ); buildAreaRootFolder = ... fullfile( thisFilesAbsolutePath, 'build_area_dir' ); handCodeFolder = ... fullfile( thisFilesAbsolutePath, 'hand_code_dir' );
To eliminate build artifacts from previously running the example, this example searches for and eliminates folders containing these by-products of previous runs.
if( 0 < exist( codeGenerationRootFolder, 'dir' ) ) clear mex; rmdir( codeGenerationRootFolder, 's' ); else % No previous codeGenerationRootFolder. end mkdir( codeGenerationRootFolder ); if( 0 < exist( buildAreaRootFolder, 'dir' ) ) clear mex; rmdir( buildAreaRootFolder, 's' ); else % No previous buildAreaRootFolder. end mkdir( buildAreaRootFolder ); if( 0 < exist( modelsFolder, 'dir' ) ) clear mex; rmdir( modelsFolder, 's' ); else % No previous modelsFolder. end mkdir( modelsFolder ); copyfile((fullfile(matlabroot,'toolbox','rtw','rtwdemos','rtwdemo_packngo.slx')), ... (fullfile(modelsFolder,'rtwdemo_packngo.slx')),'f'); if( 0 < exist( handCodeFolder, 'dir' ) ) clear mex; rmdir( handCodeFolder, 's' ); else % No previous handCodeFolder. end mkdir( handCodeFolder ); copyfile((fullfile(matlabroot,'toolbox','rtw','rtwdemos','rtwdemo_packngo','main.c')), ... (fullfile(handCodeFolder,'main.c')),'f'); copyfile((fullfile(matlabroot,'toolbox','rtw','rtwdemos','rtwdemo_packngo','main.h')), ... (fullfile(handCodeFolder,'main.h')),'f'); directoriesToAddToMatlabPathCellStr = ... { ... thisFilesAbsolutePath, ... modelsFolder ... }; for directoryIndex = 1 : numel( directoriesToAddToMatlabPathCellStr ) currentDirectory = directoriesToAddToMatlabPathCellStr{ directoryIndex }; addpath( currentDirectory ); end
In this example, the code generation configuration for the rtwdemo_packngo model enables the Generate code only parameter (GenCodeOnly) and enables the Package code and artifacts parameter (PackageGeneratedCodeAndArtifacts). These options direct the code generator to create a packNGo archive (.zip file) and stop the build process without compiling the generated code. Compilation occurs later with integrated custom code that replaces the generated main.c file.
cd( codeGenerationRootFolder );
modelBaseName = 'rtwdemo_packngo';
open_system( modelBaseName );
slbuild( modelBaseName );
close_system( modelBaseName );

When using the toolchain approach for the build process, you can extract build information from the generated makefile. The information includes source files, dependency files, and macro definitions and values that appear in the makefile. With current working folder set to the folder containing the generated makefile, rtwdemo_packngo.mk, in the Command Window, type:
cd( 'rtwdemo_packngo_grt_rtw' ); system('gmake -f rtwdemo_packngo.mk info')

For information about performing a similar operation on Windows® platforms, see the model.bat description in Manage Build Process Files (Simulink Coder).
To integrate the generated code and custom code, this example moves the files to a common location for the build process. The archive from the packNGo option is unzipped.
cd( buildAreaRootFolder ); generatedPackNGoArchiveShortName = ... [ modelBaseName, '.zip' ]; filesToCopyCellStr = ... { ... fullfile( codeGenerationRootFolder, generatedPackNGoArchiveShortName ), ... fullfile( handCodeFolder, 'main.h' ), ... fullfile( handCodeFolder, 'main.c' ) ... }; fileCopyFunctionHandle = ... @( sourceFileFullName )copyfile( sourceFileFullName, buildAreaRootFolder ); for sourceFileIndex = 1 : numel( filesToCopyCellStr ) currentSourceFile = filesToCopyCellStr{ sourceFileIndex }; fileCopyFunctionHandle( currentSourceFile ); end generatedPackNGoArchiveDestinationFullName = ... fullfile( buildAreaRootFolder, generatedPackNGoArchiveShortName ); unzip( generatedPackNGoArchiveDestinationFullName );
To compile the generated code and integrated custom code, this example constructs a build command for the gcc compiler and tools that:
Compiles the generated and custom source files
Specifies the required folders where the preprocessor can locate included header files
Provides the correct -D arguments for preprocessor macros that the generated code requires
The generated source files are in a folder extracted from the packNGo archive (.zip file). The file name combines the:
Model name
System target file (selected in the model configuration set)
Original code generation folder
generatedCodeSubFolderName = ... [ modelBaseName, '_grt_rtw' ]; generatedCodeFolderFullName = ... fullfile( buildAreaRootFolder, 'code_generation_area_dir', generatedCodeSubFolderName ); sharedCodeFolderFullName = fullfile( buildAreaRootFolder, 'code_generation_area_dir', 'slprj', 'grt', '_sharedutils'); sourceFileFullNamesCellStr = ... { ... fullfile( buildAreaRootFolder, 'main.c' ), ... fullfile( generatedCodeFolderFullName, 'rtwdemo_packngo.c' ) ... };
The required header file folders include:
Custom header file locations
Generated header file locations
Locations that contain files that the packNGo operation copied from the MATLAB installation folders to the packNGo archive
[ ~, matlabReleaseFolderName ] = fileparts( matlabroot() ); headerFileDirectoriesCellStr = ... { ... buildAreaRootFolder, ... generatedCodeFolderFullName, ... sharedCodeFolderFullName, ... fullfile( buildAreaRootFolder, matlabReleaseFolderName, 'extern', 'include' ), ... fullfile( buildAreaRootFolder, matlabReleaseFolderName, 'simulink', 'include' ) ... };
There are a number of preprocessor macros that must be defined to guide conditional compilation in the code. The macro names and values can be copied from the defines.txt file in the generated code folder.
commandLineDefinesCellStr = ... { ... 'MODEL=rtwdemo_packngo', ... 'NUMST=1', ... 'NCSTATES=0', ... 'HAVESTDIO', ... 'RT', ... 'USE_RTMODEL', ... 'UNIX', ... 'MAT_FILE=0', ... 'INTEGER_CODE=0', ... 'MT=0', ... 'CLASSIC_INTERFACE=0', ... 'ALLOCATIONFCN=0', ... 'ONESTEPFCN=1', ... 'TERMFCN=1', ... 'MULTI_INSTANCE_CODE=0', ... 'TID01EQ=0' ... };
After gathering the source, header, folder, and macro information for the build command into cell array data, this example constructs the build command by reorganizing this data as properly-formed strings. The strings serve as part of a compilation command.
commandLineDefinesCompilerArgumentString = ... strjoin( strcat( '-D', commandLineDefinesCellStr ), ' ' ); sourceFilesCompilerArgumentString = ... ['"' strjoin( sourceFileFullNamesCellStr, '" "' ) '"']; inclusionDirectoriesCompilerArgumentString = ... ['-I"' strjoin(headerFileDirectoriesCellStr, '" -I"') '"']; compilationCommandString = ... [ ... 'gcc', ' ', ... '-v', ' ', ... sourceFilesCompilerArgumentString, ' ', ... commandLineDefinesCompilerArgumentString, ' ', ... inclusionDirectoriesCompilerArgumentString ... ];
The compilation command is:
[ compilationResult, compilationOutput ] = ...
system( compilationCommandString );
The results use operating system conventions for the return values because "system(...)" returns the results from the operating system. As a result, "0" indicates success, instead of "1"/"true.
assert( ( 0 == compilationResult ), compilationOutput ); disp( compilationOutput );

This example shows how to use packNGo to relocate code and integrate custom code with generated code. These techniques ease relocating generated code to other platforms (for example, Linux® to Windows®). The sections of this example that show how to construct the build command provide information that supports code relocation.
The build command on the target platform (for example, Microsoft Visual C/C++ MSVC on Windows®) is as close as possible to the build tool flags and definitions in the build command on the source platform (for example, gcc on Linux®). Some flags and definitions are required (for example, list of source and dependency files). Other flags are optional (for example, compiler optimizations vary among compilers).
