Hi,

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 executable 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?

Are you generating and compiling the code on linux? If so, you should see a file called function_x1 in your pwd. That's the executable, not main.o. If you don't see that file, please paste the output of !ls -l in the folder from which you ran codegen.
