Hi

Can you post the output of version-script

hazel · 04-24-2016, 10:58 AM

Why are you using sudo? Everything in chapter 5 should be carried out as the lfs user.

Happen to me once, although not in LFS project.

Probably in your host system, you upgraded C compiler, but not for the C++ compiler.
Try to upgrade C and C++ compiler, then try re-building LFS from the start.

Hope that will work for you too.
