@wajlh please build the esp-at project according to https://docs.espressif.com/projects/esp-at/en/latest/Compile_and_Develop/How_to_clone_project_and_compile_it.html

[wajlh]

@ustccw thank you for your reply . I used "ESP-IDF Tools Installer" to install the windows environment and executed step 1: install python>=3.8 step 2: install pip step 3: install the following python packages with pip: python -m pip install pyyaml xlrd The test "esp-idf\examples\ethernet\eth2ap" project compiles normally. But the ESP-AT project cannot be compiled normally, and the log is the same as before. Do I have any other issues that I need to pay attention to?

[ustccw]

@wajlh esp-at uses ./build.py build, other than idf.py build. please try again and provide the compile log.

I have exactly the same problem. I think the problem is about the IDF_PATH but I don't undestand where I have the problem. the command :

build.py menuconfig work fine and i can set the platform etc...

but when I call :

build.py build the log is:

D:\Progetti\ESP32\Progetti_ESP\Progetti_ESP\ESP_AT_from_git\esp-at>build.py menuconfig module_name WROOM-32 platform_name=ESP32,module_name=WROOM-32 Usage: esp-idf\tools\idf.py [OPTIONS] COMMAND1 [ARGS]... [COMMAND2 [ARGS]...]...

ESP-IDF CLI build management tool. For commands that are not known to idf.py an attempt to execute it as a build system target will be made.

Options: --version Show IDF version and exit. --list-targets Print list of supported targets and exit. -C, --project-dir PATH Project directory. -B, --build-dir PATH Build directory. -w, --cmake-warn-uninitialized / -n, --no-warnings Enable CMake uninitialized variable warnings for CMake files inside the project directory. (--no- warnings is now the default, and doesn't need to be specified.)

-v, --verbose Verbose build output. --ccache / --no-ccache Use ccache in build. Disabled by default, unless IDF_CCACHE_ENABLE environment variable is set to a non- zero value.

-G, --generator [Ninja|MinGW Makefiles] CMake generator. -D, --define-cache-entry TEXT Create a cmake cache entry. This option can be used at most once either globally, or for one subcommand. -b, --baud INTEGER Baud rate for flashing. The default value can be set with the ESPBAUD environment variable. This option can be used at most once either globally, or for one subcommand.

-p, --port TEXT Serial port. The default value can be set with the ESPPORT environment variable. This option can be used at most once either globally, or for one subcommand.

--help Show this message and exit.

Can you help me ?

[wajlh]

@riccardobritti82 I gave up the windows OS method,because using"./build.py build" method was also unsuccessful. and used Ubuntu OS is ok

[riccardobritti82]

I have solved the problem on windows... The guide is not clear, but now with the correct sequence, it work correctly Thanks

[MaJerle]

@riccardobritti82 can you share the sequence?

[moltonim]

@riccardobritti82 please share the sequence- Dai Riccardo condividi!!!

[ustccw]

@wajlh @riccardobritti82 docs updated. esp-at release/v2.4.0.0 and master branch simplfied the compile workflow. just run python build.py install and python build.py build to build the esp-at project, could you please have a try? see this doc for more details: https://docs.espressif.com/projects/esp-at/en/latest/esp32/Compile_and_Develop/How_to_clone_project_and_compile_it.html
