How to call matlab generated function from c program?

1 次查看(过去 30 天)
Hi,
I am new to Matlab coder and would like to use generated functions in a project. I wrote few function implementations, say
objects = fuse_detections(frame_r, frame_c, ldr, ts)
in matlab and generated c code using Matlab coder. C code for the function implementations are generated successfully. I want to call the generated functions, by passing arguments and get values, from an other c program (which is a normal c program). I am aware that I should link generated object files (.o files) with the c program in order to use those functions. I did link .o files and .c files using ninja. How do I call those generated functions from my c program?

You have to include the appropriate header files which contains the generated function declaration. Then you can directly call those functions from your other C/C++ coder. While compiling the entire application, you need to link the library appropriately.
Below document explains how to use the generated dll in Visual Studio and how to call it in a new C/C++ coder :
You can also generate a sample example main file and take a look at it on how to use the generated functions :
Hope this will be helpful

Thanks for your reply.
I followed the instructions for generating code as dll and used with VS 2019. It did worked as expected. Unfortunately, our deployement system is linux. So I tried to generate code using Matlab coder for library along with main file. I also assigned generate and compile option in order to create output for the generated main file. When I tried to run the complied main file, i.e., main.o, in the terminal, it returned permission denied, then tried execute as superuser, it returned command not found. I also tried chmod +x but it returned cannot execute binary file, exec format error.
I used the following configuration for code generation
cnfig = coder.config('lib');
cnfig.GenerateExampleMain = 'GenerateCodeAndCompile';
cnfig.GenerateReport = true;
codegen -config cnfig function_x1 -args params
May I know what went wrong here?
How do I solve this issue?
