Legato Nested Component

Legato Application Framework
1

Hi,

Can somebody please help me understand what is Legato Nested Component in Legato Application Framework? When Do I create Legato Component and when should I create Legato Nested Component?

Should I create my static/shared library separately and import to Legato Application Framework or should I go for creating a component in Legato which can be used my other Legato application? Which one is a better approach? Please correct me if my understanding is wrong because I am a novice in Legato.

Thanks,
Yogesh

Hi,

In an legato application, you can create several components by right click the project → New → Legato Nested Component.
BTW, how are you going to create static/shared library separately ? I don’t see such option in Develop studio.

Hi @daav

I am getting Unresolved Inclusion error when I include in Legato Application source file.

Please take a look at my “Preprocessor Include Paths” below.

Thanks,
Yogesh

Even by using nested components, if you’re not using the api files mechanism, you need to specify where are your headers from one component to another, by using cflags sections.

Hi @daav

I am getting Unresolved Inclusion error for “iostream”. Do I need to use cflags mechanism even for C++ Built-in library?

Thanks,

Hi @yogesh.tyagi

iostream is a C++ header.
It will get resolved only if you include it from a .cpp file.

Thanks @daav. It’s working now.
