Control Build Process Compiling and Linking
After generating code for a model, the build process determines whether to compile and link an executable program. Various factors guide this determination:
Generate code only option
When you select this option, the code generator produces code for the model, including a makefile.
Generate makefile option
When you clear this option, the code generator does not produce a makefile for the model. You must specify post code generation processing, including compilation and linking, as a user-defined command, as explained in Customize Post-Code-Generation Build Processing.
The Microsoft® Visual C++® Project Makefile versions of the
grtand Embedded Coder® target configurations generate a Visual C++ project makefile (
). To build an executable, you must open
in the Visual C++ IDE and compile and link the model code.
HOSTtemplate makefile variable
The template makefile variable
HOSTidentifies the type of system upon which your executable is intended to run. The variable can be set to one of three possible values:
HOSTis set to
UNIXin template makefiles designed for use with The Open Group UNIX® platforms (such as
grt_unix.tmf), and to
PCin the template makefiles designed for use with development systems for the PC (such as
If the Simulink® software is running on the same type of system as the system specified by the
HOSTvariable, then the executable is built. Otherwise,
HOST = ANY, an executable is still built. This option is useful when you want to cross-compile a program for a system other than the one that the Simulink software is running on.
Otherwise, processing stops after generating the model code and the makefile; the following message is displayed on the MATLAB® command line.
### Make will not be invoked - template makefile is for a different host
