Hi,

I am new to ST platform, i am facing an issue as below.

C:/Users/Yuvaraj/Desktop/Test/1/Middlewares/Third_Party/LwIP/src/apps/http/fs.c', needed by 'Middlewares/LwIP/apps/http/fs.o'. Stop

I am opened the project from examples codes.

Can anyone help ? How to resolve this?

I don't know how you did that copy.

You need to be sure you have the complete project folder structures including Middlewares/Third_Party/LwIP/ 

Go to your project folder and check if you have that Middlewares/Third_Party/LwIP folder.

If not that means there is something wrong with your project.

As I said previously you need to clone with the --recursive option from Github, otherwise it won't work.

Hello @Yuvi89 and welcome to the ST community,;

From which link you've downloaded the source code? from this link? or from Github in this link?

If you've downloaded it from the from Github did you clone with the recursive option --recursive?

Please refer to this knowledge base article: Downloading STM32Cube packages from GitHub correctly

    I'm not quite sure what you mean here exactly.

    But when copying it to another PC, you most probably need to adapt the project location / paths.

    Check if this path / pathes are correct.

    Alternatively clone it via git on you second PC, instead of copying it.
