Can't make the built

[Muhammadmudassir180]

Hi, i am trying to built Px4flow, when i try to run "make" command for built. I get the following error. i think there is a conflict between the "gcc-arm-none-eabi" with the source repository. I am new to this. Need your guidance. the links are not working that are provided in repository. if there is a problem with version of "gcc-arm-none-eabi", kindly do tell me. I am using windows 11.
Thanks in advance.

1. the main problem is here, compiler grabbed std library along:

-nostdlib or -nostartfiles flag would probably help.

2. the repo is in a rather dead state, so... best of luck.
