Memory usage display after compile

Willem43 · June 17, 2022, 3:35pm

When compiling, with verbose enabled, using the following nightly:

Version: 2.0.0-rc7-nightly-20220610 Date: 2022-06-10T03:28:34.636Z CLI Version: 0.23.0 [899dc91b] Copyright © 2022 Arduino SA

the IDE displays the following at the end of the compile (two separate compiles)

Using library SPI at version 1.0 in folder: C:\Users\Willem\AppData\Local\Arduino15\packages\MiniCore\hardware\avr\2.1.3\libraries\SPI Using library LiquidCrystal_I2C-master at version 1.1.4 in folder: C:\Users\Willem\Documents\Arduino\libraries\LiquidCrystal_I2C-master Using library Wire at version 1.0 in folder: C:\Users\Willem\AppData\Local\Arduino15\packages\MiniCore\hardware\avr\2.1.3\libraries\Wire "C:\\Users\\Willem\\AppData\\Local\\Arduino15\\packages\\arduino\\tools\\avr-gcc\\7.3.0-atmel3.6.1-arduino7/bin/avr-size" -A "C:\\Users\\Willem\\AppData\\Local\\Temp\\arduino-sketch-290FF54C0C4263285D3AA5E61335C346/1614_UNO_SPI.ino.elf" Sketch uses 7226 bytes (22%) of program storage space.

Maximum is 16384 bytes. Global variables use 211 bytes (10%) of dynamic memory, leaving 1837 bytes for local variables. Maximum is 2048 bytes. -------------------------- Compilation complete.

However, when using the latest nightly:

Version: 2.0.0-rc7-nightly-20220617 Date: 2022-06-17T03:30:29.334Z CLI Version: 0.23.0 [899dc91b] Copyright © 2022 Arduino SA

we get the following at the end of the same compiles

Using library SPI at version 1.0 in folder: C:\Users\Willem\AppData\Local\Arduino15\packages\MiniCore\hardware\avr\2.1.3\libraries\SPI Using library LiquidCrystal_I2C-master at version 1.1.4 in folder: C:\Users\Willem\Documents\Arduino\libraries\LiquidCrystal_I2C-master Using library Wire at version 1.0 in folder: C:\Users\Willem\AppData\Local\Arduino15\packages\MiniCore\hardware\avr\2.1.3\libraries\Wire "C:\\Users\\Willem\\AppData\\Local\\Arduino15\\packages\\arduino\\tools\\avr-gcc\\7.3.0-atmel3.6.1-arduino7/bin/avr-size" -A "C:\\Users\\Willem\\AppData\\Local\\Temp\\arduino-sketch-290FF54C0C4263285D3AA5E61335C346/1614_UNO_SPI.ino.elf" -------------------------- Compilation complete.

No memory usage information. Can we please have the previous memory usage information displayed again. (Or am I doing something funny?)

Thanks so much for your report @Willem43. I am able to reproduce the bug and have submitted a formal report to the Arduino IDE developers:

github.com/arduino/arduino-ide

Last lines of compilation output are not printed

conclusion: resolved status: in progress topic: code type: imperfection topic: CLI criticality: high

### Describe the problem 🐛 The last lines of compilation output are not shown… in Output panel ### To reproduce 1. Select **File > Preferences...** from the Arduino IDE menus. 1. Uncheck the box next to **Show verbose output during > `☑` compile**. **ⓘ** The issue occurs with the verbose output as well. This is done only to produce more simple output for the demo. 1. Click the <kbd>**OK**</kbd> button. 1. Select **Tools > Board > Arduino AVR Boards > Arduino Uno** from the Arduino IDE menus. **ⓘ** The issue is not specific to this board. A board selection is specified only to ensure the output described here in the demo will be consistent with that seen by those who are reproducing it. 1. Select **Sketch > Verify/Compile** from the Arduino IDE menus. 1. Wait for the compilation process to finish. 1. If the issue does not occur, repeat the process from step 5 until it does occur. 🐛 The memory usage output is not shown: ```text -------------------------- Compilation complete. ``` The output should be: ```text Sketch uses 444 bytes (1%) of program storage space. Maximum is 32256 bytes. Global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes for local variables. Maximum is 2048 bytes. -------------------------- Compilation complete. ``` ### Expected behavior All lines of compilation output ### Arduino IDE version 2.0.0-rc7-snapshot-94ceefd ### Operating system Windows, Linux ### Operating system version Windows 10, Ubuntu 20.04 ### Additional context I bisected the issue to https://github.com/arduino/arduino-ide/commit/4c6243176ca5e66635fde4107e217f1b9666eb62 (does not occur when using the build for https://github.com/arduino/arduino-ide/commit/a8047660a6e23fa41bc42457cf27e53bfe5798d8). --- The number of missing lines varies. This is easier to observe with verbose compilation output enabled. Sometimes the line showing the `avr-size` command that would be expected immediately before the memory usage lines is printed: ```text [...] "C:\\Users\\per\\AppData\\Local\\Arduino15\\packages\\arduino\\tools\\avr-gcc\\7.3.0-atmel3.6.1-arduino7/bin/avr-objcopy" -O ihex -R .eeprom "C:\\Users\\per\\AppData\\Local\\Temp\\arduino-sketch-13926962AEE9C72B0EB120253E6668CD/sketch_jun17a.ino.elf" "C:\\Users\\per\\AppData\\Local\\Temp\\arduino-sketch-13926962AEE9C72B0EB120253E6668CD/sketch_jun17a.ino.hex" "C:\\Users\\per\\AppData\\Local\\Arduino15\\packages\\arduino\\tools\\avr-gcc\\7.3.0-atmel3.6.1-arduino7/bin/avr-size" -A "C:\\Users\\per\\AppData\\Local\\Temp\\arduino-sketch-13926962AEE9C72B0EB120253E6668CD/sketch_jun17a.ino.elf" -------------------------- Compilation complete. ``` Other times it is not: ```text [...] "C:\\Users\\per\\AppData\\Local\\Arduino15\\packages\\arduino\\tools\\avr-gcc\\7.3.0-atmel3.6.1-arduino7/bin/avr-objcopy" -O ihex -R .eeprom "C:\\Users\\per\\AppData\\Local\\Temp\\arduino-sketch-13926962AEE9C72B0EB120253E6668CD/sketch_jun17a.ino.elf" "C:\\Users\\per\\AppData\\Local\\Temp\\arduino-sketch-13926962AEE9C72B0EB120253E6668CD/sketch_jun17a.ino.hex" -------------------------- Compilation complete. ``` More rarely, one or two of the memory usage lines are shown. --- Originally reported at https://forum.arduino.cc/t/memory-usage-display-after-compile/1003909 ### Issue checklist - [X] I searched for previous reports in [the issue tracker](https://github.com/arduino/arduino-ide/issues?q=) - [X] I verified the problem still occurs when using the latest [nightly build](https://github.com/arduino/arduino-ide#nightly-builds) - [X] My report contains all necessary details
