IDE name: Eclipse/console make + esp-idf 3.0.2
Computer OS: Linux 4.9.0-9-rt-amd64 #1 SMP PREEMPT RT Debian 4.9.168-1+deb9u5 (2019-08-11) x86_64 GNU/Linux

Description:

when i 'make' i getting next error:

when i comments line "long random(long, long);" in arduino.h, i got another error:

editing BLEDevice.cpp

        esp_err_t errRc = esp_ble_gap_update_whitelist(true, *address.getNative()), BLE_WL_ADDR_TYPE_PUBLIC);  // True to add an entry.

next same with _update_blacklist (below this function in same file). editing - same (add ", BLE_WL_ADDR_TYPE_PUBLIC")

next:

/usr/media/Programming/esp/Projects/homeauto/components/arduino/libraries/BLE/src/BLEAdvertisedDevice.cpp:` In member function 'std::__cxx11::string BLEAdvertisedDevice::toString()':
/usr/media/Programming/esp/Projects/homeauto/components/arduino/libraries/BLE/src/BLEAdvertisedDevice.cpp:509:30: error: 'snprintf' output may be truncated before the last format character [-Werror=format-truncation=]
   snprintf(val, sizeof(val), "%d", getTXPower());

modifing BLEAdvertisedDevice.cpp:
adding

#ifndef snprintf_nowarn(...)
#define snprintf_nowarn(...) (snprintf(__VA_ARGS__) < 0 ? abort() : (void)0)
#endif

adding _nowarn to all snprintf

Next:

CXX build/arduino/libraries/BLE/src//BLEUUID.o
/usr/media/Programming/esp/Projects/homeauto/components/arduino/libraries/BLE/src/BLEUUID.cpp: In member function 'std::__cxx11::string BLEUUID::toString()':

doing same as last? but getting next... (not helped)

/usr/media/Programming/esp/Projects/homeauto/components/arduino/libraries/BLE/src/BLEUUID.cpp:19:39: error: '%02x' directive output truncated writing 2 bytes into a region of size 1 [-Werror=format-truncation=]

and now i'm stuck
i know that downgrade of gcc and removing some flags will fix issue, but, realy, let prepare code to above vertions of compillers. how to fix last issue, who knows?

The newest supported version of esp-idf is v3.2.3. This uses the older gcc toolchain. Once v4.0 gets to stable, the new toolchain will be supported. This is a downstream, community project. We do not support experimental builds.

where to get toolchain for v3.2.3? espressif have link only for latest (that i have), and it makes many errors :(

sorry, found on github. goin to make install script

[lbernstone]

There already is a script:

thanks

now making script to automate full installation with esp-idf and adding lib TFT_eSPI (later will be edited copy)

here link

[lbernstone]

There's a script for that too 😄

There's a script for that too smile

im late ((((((
XD

but in my script you can choose version (tag-list) of idf before installing it %)
