I apologise in advance for the poor formatting of this post this is new to me

I am currently trying to build LFS 7.8 using gentoo as the host system, unfortunately I can’t figure out how to fix this compiling error on GCC pass 1

The only theory i have is that it would come from the fact that the packages specified in the Host Requirements are newer versions on gentoo

here is the output of the version check script in Host Requirements :

Apart from that I am lost

(Yes i am aware this is an old version of LFS and if i could do the latest one i would)

Thank you!
