Compilation error #264

Closed jbrepogmailcom closed 4 years ago

jbrepogmailcom commented 4 years ago

Hello, I have commented in other issue, but that has been closed, so I repeat here. I am getting following error during compiling for esp8266 and esp32:

/home/janbenes/Dropbox/Apps-180116/Arduino/libraries/IBM_LMIC_framework/src/hal/hal.cpp: In function 'void hal_printf_init()': /home/janbenes/Dropbox/Apps-180116/Arduino/libraries/IBM_LMIC_framework/src/hal/hal.cpp:223:54: error: '_FDEV_SETUP_WRITE' was not declared in this scope fdev_setup_stream (&uartout, uart_putchar, NULL, _FDEV_SETUP_WRITE); ^ /home/janbenes/Dropbox/Apps-180116/Arduino/libraries/IBM_LMIC_framework/src/hal/hal.cpp:223:71: error: 'fdev_setup_stream' was not declared in this scope fdev_setup_stream (&uartout, uart_putchar, NULL, _FDEV_SETUP_WRITE); ^ Multiple libraries were found for "lmic.h" Used: /home/janbenes/Dropbox/Apps-180116/Arduino/libraries/IBM_LMIC_framework Multiple libraries were found for "SPI.h" Used: /home/janbenes/.arduino15/packages/esp8266/hardware/esp8266/2.5.2/libraries/SPI Using library IBM_LMIC_framework at version 1.5.0 arduino-0 in folder: /home/janbenes/Dropbox/Apps-180116/Arduino/libraries/IBM_LMIC_framework Using library SPI at version 1.0 in folder: /home/janbenes/.arduino15/packages/esp8266/hardware/esp8266/2.5.2/libraries/SPI exit status 1 Error compiling for board Generic ESP8266 Module.

You're using an older version:

Using library IBM_LMIC_framework at version 1.5.0 arduino-0 in folder: /home/janbenes/Dropbox/Apps-180116/Arduino/libraries/IBM_LMIC_framework

The latest is 1.5.0-arduino-3, but I just remembered that the Arduino IDE mis-sorts these version numbers, so it probably installs the wrong version by default...

You were right, I had to manually select version in the Library manager. Latest available was arduino-2, which gives compilation error "This example requires DISABLE_INVERT_IQ_ON_RX to be set. Update config.h in the lmic library"

Is this error fixed in version arduino-3? I have uncommented that line in config.h, but the explanation says that uncommenting will cause that gateway is not seen but the nodes are. For LoRaWAN we want to see the gateway but not nodes, is that right?

Then maybe the newest version is not index by Arduino yet, I have only just pushed it yesterday.

No, this error should be resolvd by changing the config as instructed. However, the example you are using is intended for raw node-to-node LoRa communication that is completely unrelated to LoRaWAN. If you worry about gateways, I suspect you're using the wrong example.
