I'm trying to build cross-compiler under Cygwin. I started with your LFS
book. I got as far as the headers-install and got a make error, trying to
compile relocs.c. I'm in section 5.6.1 right before build/install of
GLibc. As you know, I'm unable to use mntfs with cygwin without converting
part of the disk to NTFS. Even then, a lot of the sections in LFS book
prior to the actual build/install processes won't work. So I'm wondering
if that's the root cause of the problem. Has anyone tried doing this under
Cygwin?
