Using own custom "rt_main.c" with system target file grt.tlc in Simulink Coder

Hi,

I would like to know whether it is possible to make grt.tlc target to point to my own custom "rt_main.c" in my own project path instead of the predefined "rt_main.c" in Matlab's installation path. Basically the line 181 in the generated makefile should ultimately be:

MAIN_SRC = <my own paht>/rt_main.c

Thanks!

I've managed to find a solution by including makecfg.m in my custom simulink library and utilizing the functions

1. setTargetProvidesMain() and
2. addSourceFiles() for including my rt_main.cpp implementation.

Hi Konstantinos,

I Understood that you want to have custom rt_main.c file in your project. This option is available in the Embedded Coder but not in the Simulink Coder.

Refer this for more information.

Hope this helps!

Hi Shanmukha,

Embedded coder is installed in my system. Could you provide instructions for customizing main in that case?

Thanks!

Refer documentation regarding Embedded Coder.
