Section 5.11.1 in book 6.3 calls for gcc to be patched with gcc-4.1.2.specs-1.patch to correct the location of the dynamic linker and to remove /usr/include from the search path.

Trying to apply this patch, however, yields every patch attempt failing with Hunk #x FAILED at xx.

Any ideas on why this might be?

EDIT: In some patched files the dynamic linker is presently listed as LINUX_DYNAMIC_LINKER, not /lib/ld-linux.so.2. Should i edit the patch file to look for this instead of ld-linux.so.2? Also, why would this be in place of the literal file name?

Are you actually trying to compile the same version of GCC or are you trying to use a different version of GCC?

Nope, at this point, you are using the previously compiled 4.1.2 version to recompile itself independent of the host system.

I should also note that some other files contain the exact lines to be replaced and still fail. I am logged in as lfs and have ownership of all of these files, so it shouldn't be a permissions issue.

Odd, I just the SVN version with full opts and the only problem is I had to replace perl with 5.9.10 not a huge problem.
I'm running kernel 6.25.10 as well and I am also using it's headers as well.

All I say is retry? A couple of time when i tryied to get 6.3 running I got a load sed syntax errors even though i copyed and pasted the syntax into the terminal.
