gcc: error: unrecognized command line option '-V'

No, you have to start again from the beginning, from Chapter 5. Make a completely new toolkit using the correct shell.

I've noticed something else which might be relevant to your problem. Both binutils and gcc are to be built "--with-system-zlib". This means that the package's internal zlib doesn't get built. Apparently libisl is needed for building it as well as for building graphite. Please check that you included this essential parameter in your gcc build, and that zlib has actually been built and installed.

I downloaded the zlib package and successfully installed it. I also added the argument "--with-system-zlib" into my command binutilis and gcc but got the same error.
When i feed my system the following commands

Code:

for file in gcc-6.3.0/config/{linux,i386/linux{,64}}.h
do
cp -uv $file{,.orig}
sed -e 's@/lib\(64\)\?\(32\)\?/ld@/tools&@g' \
-e 's@/usr@/tools@g' $file.orig > $file
echo '
#undef STANDARD_STARTFILE_PREFIX_1
#undef STANDARD_STARTFILE_PREFIX_2
#define STANDARD_STARTFILE_PREFIX_1 "/tools/lib/"
#define STANDARD_STARTFILE_PREFIX_2 ""' >> $file
touch $file.orig
done

I get the following output

Code:

cp: cannot stat 'gcc-6.3.0/config/i386/linux.h': No such file or directory
-bash: gcc-6.3.0/config/i386/linux.h: No such file or directory
-bash: gcc-6.3.0/config/i386/linux.h: No such file or directory
touch: cannot touch 'gcc-6.3.0/config/i386/linux.h.orig': No such file or directory
cp: cannot stat 'gcc-6.3.0/config/i386/linux64.h': No such file or directory
-bash: gcc-6.3.0/config/i386/linux64.h: No such file or directory
-bash: gcc-6.3.0/config/i386/linux64.h: No such file or directory
touch: cannot touch 'gcc-6.3.0/config/i386/linux64.h.orig': No such file or directory

i checked in my config folder and i don't have an i386 folder, any ideas on how i can resolve this? I thought when i extracted my gcc.tar folder all the necessary libraries would be created for me.
Also i'm running an x86_64 machine. From research on the Internet it looks like the i386 is for 32bit machines, i could be wrong.

? Why ? The Ubuntu system zlib is completed with : sudo apt install zlib1g-dev

Some misunderstanding here! We are talking about building Linux From Scratch. Ubuntu is merely the build host and, by this stage of the proceedings, should be providing only the kernel and dynamic directories. All the userland software is on the new partition, either in the /tools tree or in the standard locations. And the build should not be asking for headers for this library.

When? It needs to be installed in the correct sequence, i.e. before binutils.

That's a chapter 5 sequence. I thought we were on chapter 6 now.

Well, this is a mix-up. You really do need to scrub everything and start again. One of the most basic requirements for building LFS is to know what your system architecture is.

The fact that your computer is 64-bit is not conclusive; what matters is the architecture of your host system. A 32-bit computer only runs 32-bit code (and yes, i386 (or i686) is the symbol for that). A 64-bit computer can run both 32-bit and 64-bit systems. Almost certainly your Ubuntu is 64-bit because most people run that now. LFS must follow the architecture of your host.

The command uname -r run in Ubuntu will tell you what architecture you have.

Scrub all the $LFS directories except /sources and start again at chapter 5. Put it down to experience!
