How to create "complex" project structures ?

Hi,

I am practically a newbie in the esp32 world and i am starting with esp-idf.

I am trying to learn make, cmake and esp-idf projects structure at least 2 weeks and i couldn't make the "complex structure" project compile yet.

The hello_world and sdio/host example compile just fine, and i was even able to integrate esp-idf into visual studio code.
Until jtag, openocd, gdb i managed to make it work inside the visual studio code and in my hardware.
All "process" below are working fine:
"build app"
"clean app"
"flash app"
"monitor"
"menuconfig"
"openocd"

At the beginning off all these learning curve, i was mixing document version, because i download the stable version v3.2.2 and i was searching by googling, which led me to different espressif documentation pages in each new search(latest idf version for example).
So i was mixing component.mk with CMakeLists.txt.

After the penny has dropped(i understant), i uninstalled all the old files of version v3.2.2 and all other tools and started a new installation from scratch with the latest version: v4.1-dev-141-ga7e8d87d3.

I am only using now the latest documentation on espressif site link: https://docs.espressif.com/projects/esp ... ystem.html, and trying to follow the project structure, but the documentation is complicated to me, because dont have examples.
I dont know what write inside the CMakeLists.txt(beyond the minimum) or in component.mk if i need yet this file.
The link site show "commands" but dont show command sintax with examples and where applicable, etc.
The hello_world example has a CMakeLists.txt in the main directory, but in the link above don't exists this file in project structure.
I am very confused.

I download a third party component and i am trying to adapter the component inside the espressif suggested structure.
The third party component has a "little long" subdirectory structure that makes sense to me.

How to tell the compiler the path or files to add to the compiling ?
There is a simple command like: add all subdirectory from "x" path ?

I need component.mk files yet or only CMakeLists.txt or i need both files in the project(dir and/or subdir) ?
Where to put this files and what write on them ?

Attached follows my entire project without the build directory.
I hope someone gives me a light at the end of the tunnel.

PS:
Why espressif doesn't adopt any open platform like netbeans and does everything "graphical" like MPLAB from microchip for example.
When i need to add a new file, the ide does all the work of adding whatever is needed to build files like makefile,
from what i understand, without the user having to understand the whole complex compilation process.
I know that understanding compilation tools is very powerful learning but it is a pain.

It is almost getting easier to program in assembly :).


Thank's.

Hi,

Now i have problems with the linkage process i think.

I would like to know how to link external libs with esp-idf, step by step if possible.


Thank's.

Hello Esp-idf team,

I need help please.
I am lost.

Give me a hand / tip.

I can update the project with the includes path corrected.

I'm pretty sure that the only problem is linking now, but i dont know how to link the external lib with the esp-idf using cmake.

Thank's.

Hi Baldhead,

Sorry to hear you've had problems making everything work. We have some improvements coming soon in the build system docs, and a major restructure is planned in the future.

You may find it helpful to look at some of the examples included with IDF, some of these have multiple components. For example, the iperf example includes "iperf" as a component:
https://github.com/espressif/esp-idf/tr ... wifi/iperf

If you will build the project with "make", you need component.mk files. This is the default method in IDF v3.x and earlier, and it is supported as the "Legacy" method in v4.x.

If you build the project with "cmake" or "idf.py" then you need CMakeLists.txt files. This is the default method in IDF v4.x, ie master branch.

We have some better IDE support coming, I know it's limited compared to some other options. One of the advantages of the build systems that ESP-IDF has is that they're very flexible, once you get the hang of them then it's possible to do a lot of different things. But I agree there is a learning curve!

I took a quick look at your project and it looks like you've made a good start. The CMakeLists.txt file in components/drv/CMakeLists.txt should be something like this:

Code: Select all

idf_component_register(SRCS "disp_spi.c"
                            "ili9341.c"
                            "tp_spi.c"
                            "xpt2046.c"
                      INCLUDE_DIRS "include"
                      REQUIRES driver
                )
Very close to what you had.

You will need to add two more similar CMakeLists.txt files in the components/lv_examples directory and the components/lvgl directory if you want these files to be compiled as part of your ESP-IDF project.

If any of the components include headers from the other components (for example if "lvgl" includes headers from "drv") then you need to put something like "REQUIRES drv" in the lvgl CMakeLists.txt file.

The file main/CMakeLists.txt needs to be a "component cmakelists" file, right now it's a copy of the top-level project CMakeLists. So try something like this:

Code: Select all

idf_component_register(SRCS "main.c"
                                     )
("main" doesn't need any REQUIRES list, it automatically includes all the other components.)

If you're still getting errors, please post the full output from the build and any other relevant details.

Hi ESP_Angus,

I am using this version: v4.1-dev-141-ga7e8d87d3.
I think this is the latest version, because i downloaded in a few days ago.

I would like to use only CMAKE for building the project, and i hope that i can build/compile in the nexts esp-idf updates.

I think i am on the right track, but..........

Attached follows the full project.

Below follows the log:

Usually undefined symbol errors in the linker output mean that some source files were not added into the build.

These two lines in the CMake output are useful because they show which components are included in the build:

... I don't see any of your project's components here are apart from "main" so probably this is a clue.

When I download your new zip file, I see that you've moved all your components from the "components" directory to a "components/ui/..." subdirectory. This means the build system can no longer see them.

You have two options:
  • Move them back. By default, the build system will only see project components where the path looks like "components/<component name>/CMakeLists.txt". Any CMakeLists file in a subdirectory under this will not be seen.
  • Set the EXTRA_COMPONENT_DIRS variable in your project CMakeLists.txt file to the path to "components/ui". This will cause the build system to also search in this directory for components. See more info here: https://docs.espressif.com/projects/esp ... -variables . Some IDF examples do this, for example: https://github.com/espressif/esp-idf/bl ... sts.txt#L5 (note that they use IDF_PATH but you will want your path to be relative to CMAKE_SOURCE_DIR)

Hi ESP_Angus,

I tried your suggestion(Set the EXTRA_COMPONENT_DIRS) and i still have the same problem.
The first suggestion i didn't even try because i need to change many include paths.

In annex follow the project.

Thank's.

Hi,

Now i am trying like the project in annex, and not build yet.
I followed some tips from techtoys on littlevgl forum.

Code: Select all

Checking Python dependencies...
Python requirements from c:\esp-idf\requirements.txt are satisfied.
Executing action: all (aliases: build)
Running ninja in directory c:\esp32projects\esp32_ili9341-master\build
Executing "ninja all"...

Re: How to create "complex" project structures ?

You shouldn't have to make this kind of change in your code:

Code: Select all

 #include "../components/ui/lvgl/lvgl.h"
The way the build system is designed, if one component REQUIRES the other component, you can just #include their headers without needing any special paths. The exact location in the filesystem should be irrelevant.

If this kind of path hacking is needed to include a header, it means that component isn't being found by the build system properly (see previous post) or one component doesn't REQUIRE the other component (probably not the case here as this looks like this is in the "main" component which automatically REQUIRES all the other component).

And because the component isn't actually included in the build, linking fails.

Sorry I don't have the time to go through the rest of the zip file. Suggest first making sure that all components are listed in the build output (see previous post), then remove all these path hacks and add REQUIRES for any component that needs to include headers from another component, and then work on any additional build failures from there.

If confused, checking the examples (like the ones I've linked above) may help.
