component include problem

[Stomper]

Hi,

I try to setup a big project with lots of components but I got stuck at component 2 - my own http_server helper component.
My plan is to setup my own project related components to keep it clean and managable.

The first component to connect the wifi was easy going and is working like expected, I built a Kconfig file to setup the wifi credetials with menuconfig and the connection is working.

After that I started to build up the http_server helper component exact the same way, but the esp_http_server.h cannot be found if I include it in my component. See the screenshot here:

As you can see, the esp_wifi.h can be included and there is no error, but the esp_http_server.h does throw an error. The error is real, not only a display problem of eclipse. I get the same error in the command line too. fullclean was run before. Also with <> instead of "" it is not working.

On the other side... if I include in the main.c - the file is found:

Why is it possible to include the esp_wifi.h in my sub component but not the esp_http_server.h ?

Am I missing something?

Best regards

It is still not working... I found in the Build Console, that the esp_http_server is registered as a component.

Every other component header file I try to include is working, but not the esp_http_server.h file.

Can somebody please cross check this?
Is it a bug in the component?

Best regards

[Stomper]

Another interesing thing is, that if I include the "old" http_server.h" file with the compiler warning, the build environment does find the file and throws the error:

CompileErro3.png (68.13 KiB) Viewed 9241 times

So the file is found by the build environment in general.

Finally I solved it!!!

This module depends on the esp_http_server but this was not stated by the idf_component register.
After adding REQUIRES statement, it compiles without errors.

160+ Views and no one saw the mistake ...

Don´t know what this means for the coding community arround here...

And it is not finally clear, why this is no problem with the wifi component.
The same compile error should have been thrown in the wifi module before...

Nobody saw the mistake because nothing obvious is known about your build/configuration files.

Don´t know what this means for the coding community arround here...

Don't think it means anything, other than people are busy and picking through another's build output isn't high on the "free" list.

And it is not finally clear, why this is no problem with the wifi component.
The same compile error should have been thrown in the wifi module before...

What I do see after sifting through the output.

1. I do see esp_http_server referenced for your main component.
2. During the compilation of your mm_http_server component, there is no reference to esp_http_server.
3. Your mm_wifi component is not in the build log other than its a dependency of main; so, can’t say.

I can only conclude that your main and/or mm_wifi components have an explicit or implicit dependency on esp_https_server. But your mm_http_server component did not (until you added it).
