lto-wrapper: fatal error: /usr/bin/avr-gcc returned 1 exit status compilation terminated.

Trying to compile the u8x8 sketch in the u8g2 library and get lto-wrapper: fatal error: /usr/bin/avr-gcc returned 1 exit status
compilation terminated. Researched it and installed board manager 1.6.21; installed
http://downloads.arduino.cc/packages/package_avr_7.3.0_index.json; and installed arduino-Makefile (yay -S arduino-mk ). Still get the error.

U8x8 is part of u8g2. U8g2 can be installed from Arduino IDE

[Gudzys]

It's installed but the full buffer u8g2 programs said there wasn't enough RAM for the local variables. Some of the u8x8 programs compile fine; this one did not. Is there a way to get around the memory limitation of the full buffer u8g2 programs? Thanks.

Use page buffer mode of u8g2 or get a uC with more RAM.

this one did not.

You mean, one of the u8x8 examples does not compile? Can you name the failing u8x8 example?

[Gudzys]

GraphicsTest gives me /usr/bin/avr-ld: error: lto-wrapper failed Also get that on some other programs outside of u8g2. Did the solutions mentioned but they did not work. Am running Arduino IDE on Manjaro Linux: that may be the problem, not your program. Some have said this is a linux bug. Thanks, Brent Sent with [Proton Mail](https://proton.me/) secure email.

u8x8 GraphicsTest compiles nicely for Arduino Uno with Arduino 1.8.4 on my system (Ubuntu Linux).

[Gudzys]

Appears to be an Arch/Manjaro linux bug.

Oh, ok
