Embedded coder for simulink model does not link libraries in the right order

Hello,

I am trying to generate an executable using a simple SImulink project using Embedded Coder for C code.

This model is calling some specific function defined into an external library let us call it libOne.a

When Embedded Coder is about to link the C code generated from my Simulink model, the order of the libraries to use is the following one:

gcc -o someExecutable libOne.a rtwshared.lib

With this wrong order, the link failed because a function called into rtwshared.lib which is defined into libOne.a is not found (which is normal error with this library order)

the right command to link should be the following:

gcc -o rtwshared.lib libOne.a

How can I configure my very very simple Simulink model so that libraires ar linked in the right order and not in the wrong reverse order ?

Thank you in advance for your help.

best regads.

Hi Didier,

I understand you are facing an issue while linking external libraries in embedded coder.

You can try to go through the documentation of “coder.EmbeddedCoderConfig”:

• Configuration parameters for C/C++ code generation from MATLAB code with Embedded Coder - MATLAB - MathWorks India

In this there’s a function called “CustomLibrary” which might help you in linking static library files with the generated code.

hello,

thank you very much for your response, I will try as soon as I can go back to my old project.

I am very happy to see someone has read my question because I did not hope to get any information for this.

As you can see, it took more than 3 years between question and answer which may seem quite long.

Nevertheless I appreciate you answering my question, I didn’t expect it anymore.

Best regards.
