I've been trying everything i found on internet and still having this problem

Answer 1

[julianh]

I fixed it like this:

At it is said is not a problem you just need to close and launch matlab from its location for that you make:

1. go to the instalation folder and search the bin folder normally in the root of your terminal you enter this: cd /usr/local/MATLAB/R2020b/bin
2. Then you wiil need to lauch activate matlab.sh in the terminal you do this: sudo ./activate_matlab.sh
3. Better activate using a file_license the activation wizard will help you to do that you will need to create an activation file using your host ID and the user name that is your ubuntu name online, then download and then activate.
4. launch matlab that is located in the same directory using: ./matlab

Enjoy

worked for me and Im enjoying it:)

This isn't a report of a problem. It states that if you want to take advantage of "simulation acceleration, model reference, and MATLAB Function Block capabilities" there is an additional step you will need to complete, one that the MathWorks installer cannot complete on its own because it would require installing a non-MathWorks product.

If you have no intention of taking advantage of those capabilities, you don't need to take action.

If you do intend to take advantage of those capabilities, you should install a supported C compiler to enable them.

Thanks for your clarification

[Shashank Rayaprolu]

But matlab doesnt get installed/ doesnt run after this message. FYI I faced this problem while installing Matlab R2020a with ubuntu 19.04

@Shashank, please start a new question as it doesn't sound like you're facing the same problem at all.

In your question, give us the full text of the error message(s) you receive.

[Nikolett Tolnay]

Hello @Shashank, I'm facing the exact same problem right now. Could you find a solution? Thanks in advance

[Zhicheng Ouyang]

Same problem. Intallation completes with the info"1. Simulink requires a C compiler for simulation acceleration, model reference, and MATLAB Function Block capabilities. It is recommended that you install a supported compiler on your machine."

MATLAB2020a is not successfully installed and cannot open.

I'm ubuntu18 user. This issue is solved after running installation again in ubuntu store.

[Lukas Schulth]

I just installed Gnu Compiler Collection using

sudo apt-get install build-essential

and restarted the Matlab installtion. The installation finished.

When I try to start Matlab I get a licensing error.

Running activare_matlab.sh throws the error: "Failed to install file: not supported".

Im using Ubuntu 20.04.1 LTS on a dual boot besides Windows 10.

[julianh]

well yes is a problem i have the compiler GCC required in my pc and still having this message. Simulink requires a C compiler for simulation acceleration, model reference, and MATLAB Function Block capabilities. It is recommended that you install a supported compiler on your machine."
