Seems so.. binutils-2.43 gcc-14.2.0 newlib-.4.0.20231231 ..no patches required for arm/riscv32 with bleeding edge newlib. foo@sdu:~/usr/src/QT$ /usr/local/QT/6500r/xgcc/arm-none-eabi/bin/arm-none- eabi-gcc -v Using built-in specs.

An actual arm cross is different. You can't build an rpi executable with the above: only for the pico (ie: embedded). For actual arm cross executables I use.. binutils-2.26.1 linux-4.19.66 gcc-14.2.0 glibc-2.28 ..but I don''t really have a use for it: whilst it builds, it may not work. I've not tested it in a long time and even when I did, it was little more than "Hello World".
