Can't compile AT firmware

[Aeroman66]

Hello,

I'm having lots of trouble trying to compile the AT firmware in order to use the A2DP commands with a ESP32 WROOM board.
My computer is a Windows 10 machine, and after following the procedure at https://docs.espressif.com/projects/esp ... le_it.html , I had the first failure on the log below, that I found to be related to the IDF_PATH variable being set, so I've delete it and after trying to compile again, I got lots of double definitions errors.
There was a previous idf installation, that was used to thest the A2DP example, but it was uninstalled previously. I've reinstalled idf and everything went fine up to the project configuration part, with menuconfig, but unfortunately I was not able to build it
Can you help me to make this work? The log output is listed below...

Thanks in advance,

Checking if Python packages are up to date...
Python requirements from C:\Work\Nodemcu\esp\esp-idf\requirements.txt are satisfied.

Done! You can now compile ESP-IDF projects.
Go to the project directory and run:

The following three methods are recommended for compiling AT firmware on windows platform：
1. Install ubuntu virtual machine
2. Use WSL
3. Use the Windows platform tools launched by Espressif

From your log, you are using IDF v4.3. So you can refer to https://dl.espressif.com/dl/esp-idf/?idf=4.3 to download tool. Run after installation, switch to AT root directory in DOS environment and follow the steps below to compile:

1. delete build directory and sdkconfig file
2. build.py menuconfig. This command will automatically download the IDF corresponding to AT.
3. enter esp-idf directory and execute install.bat and export.bat
4. back to the AT root directory and execute build.py build command

I Have the same issue on a Linux server with Ubuntu VERSION="20.04.3 LTS (Focal Fossa)"

within 3 files the type is not found , i assume a Header is missing ?

../esp-idf/components/efuse/src/esp_efuse_api.c:35:8: error: unknown type name '_lock_t'
../esp-idf/components/mbedtls/port/esp32/bignum.c:31:8: error: unknown type name '_lock_t'
../esp-idf/components/spi_flash/partition.c:65:8: error: unknown type name '_lock_t'



if someone have a hint for me , i will not dive into this project i will only use it.
After a successful build i will only change the Setup to have ethernet aktivated for the esp32,
so i can not use the prebuilded ones.

Thanks Joachim

It is recommended that you execute the git submodule update --init --recursive command in the esp-idf directory in ESP-AT root directory. If it can't be solved, you can post your compilation steps for a look.
