Compilation error: conflicting declaration 'USBCDC USBSerial'

[Exryz]

I had problems with running the compile.sh script where I get this error:

bugUtils.h: No such file or directory
 #include "Arduino_DebugUtils.h"
          ^~~~~~~~~~~~~~~~~~~~~~
compilation terminated.bugUtils.h: No such file or directory
 #include "Arduino_DebugUtils.h"
          ^~~~~~~~~~~~~~~~~~~~~~
compilation terminated.

but when I tried compiling through the Arduino IDE, it goes through the error but I end up with a new one

Compilation error: conflicting declaration 'USBCDC USBSerial'

here's the full error error.txt

Update, after redoing everything and applying the patch manually to my packages folder where my platforms are installed. Im now having an entirely new problem. This error is being made through the compile.sh script. The same error above persists when trying to compile through the Arduino IDE.

The error is specific to Windows. The problem is that when compiling on a Windows machine the "esp32" platform is configured to use the executable tools/gen_esp32part.exe instead of tools/gen_esp32part.py (which is used on Linux and macOS machines):

https://github.com/arduino/arduino-esp32/blob/8ef25a73ff8cc175836b0f65a6b276d8aed324bd/platform.txt#L27

tools.gen_esp32part.cmd=python3 "{runtime.platform.path}/tools/gen_esp32part.py"
tools.gen_esp32part.cmd.windows="{runtime.platform.path}/tools/gen_esp32part.exe"

The espressif/arduino-esp32 repository maintainers did not keep tools/gen_esp32part.exe in sync with changes to the tools/gen_esp32part.py script source code so the tools/gen_esp32part.exe at the submodule's https://github.com/arduino/arduino-esp32/commit/8ef25a73ff8cc175836b0f65a6b276d8aed324bd was generated from the antiquated version of the script at https://github.com/arduino/arduino-esp32/commit/5502879a5b25e5fff84a7058f448be481c0a1f73, which was prior to the addition to the tools/gen_esp32part.py script of support for the undefined partition type keyword:

https://github.com/arduino/arduino-esp32/blob/5502879a5b25e5fff84a7058f448be481c0a1f73/tools/gen_esp32part.py#L51-L68

SUBTYPES = {
    APP_TYPE: {
        'factory': 0x00,
        'test': 0x20,
    },
    DATA_TYPE: {
        'ota': 0x00,
        'phy': 0x01,
        'nvs': 0x02,
        'coredump': 0x03,
        'nvs_keys': 0x04,
        'efuse': 0x05,
        'esphttpd': 0x80,
        'fat': 0x81,
        'spiffs': 0x82,
    },
}

tools/gen_esp32part.exe was recently rebuilt from the up-to-date script code in https://github.com/espressif/arduino-esp32/commit/86040af7540b1e4688faeceba3063d894a88a52c so the best solution would probably be to just update the submodule.

Update: fixed the current problem and was able to run the compile.sh script without any errors. Went to the unor4wifi.csv file and left the subtype blank instead of 'undefined'

Im Stuck at the exit status 2 error, also on windows. Cant compile.

Also what csv file are you referring too? i dont see any csv files.

i managed to compile on my windows machine after doing what per1234 suggested. Thanks!
