I tried running this if that helps: The /usr/local/include folder on my pi is empty (it's pretty fresh) |

I tried sourcing /etc/environment and running with the minimal PATH: I am running my host on archlinux, do you think that could be related ? |

thanks, copying the .o from sysroot/usr/lib/arm-linux-gnueabihf to sysroot/usr/lib seems to work for this case. but this means that the compiler does not liook into |

sudo ln -sf /usr/lib/arm-linux-gnueabihf/crti.o /usr/lib/crti.oHonestly speaking sysroot is extremely complicate to handle. I might need someone from community to help here handling sysroot while compiling properly. |
