Build error on Fedora 35

[bfnserra]

Hello Proxmark team !

I'm trying to build proxmark on fedora 35 (arm-none-eabi-gcc 11.1.0) and got the following error:

How did you manage to come that far? I am already stuck at compiling version.c:

arm-none-eabi-gcc -c -I../include -I../common -I. -Wall -Werror -pedantic -std=c99 -I. -Os -mthumb -mthumb-interwork -o obj/version.o version.c 
In file included from ../include/usb_cmd.h:21,
                 from ../include/proxmark3.h:17,
                 from version.c:1:

@pwpiwi - looks like you have a different error, probably related to some dependencies... ?
I googled "stdint.h: No such file or directory" and found some interesting things, hope it helps !

[pwpiwi]

@bnfserra: sudo dnf install arm-none-eabi-newlib fixed my issue on Fedora. I now can confirm your issue. Looking into it..

[bfnserra]

In the meantime, I was able to start playing via docker : docker run -it --device="/dev/ttyACM0" --privileged -v /tmp/share:/opt/proxmark3/Data iceman1001/proxmark3:1.7.0
Hope it helps.

I made these changes to have it compile:

[AndreKR]

Same issue (array subscript 'uint32_t {aka long unsigned int}[0]' is partly outside array bounds of 'char[1]') on Windows following these instructions.

[iceman1001]

you can also try https://github.com/rfidresearchgroup/proxmark3 which is a more up-to-date client / firmware for your proxmark3

[AndreKR]

The changes from @crazyquark's commit solved the issue.

[nyetwurk]

This is not the way you're supposed to use linker defined symbols.
It should be

extern uint8_t _bootrom_start[], _bootrom_end[], _flash_start[], _flash_end[];

[nyetwurk]

https://github.com/rfidresearchgroup/proxmark3 has

extern uint32_t _bootrom_start[], _bootrom_end[], _flash_start[], _flash_end[], _osimage_entry[];

that makes a ton more sense. thanks.
