Facing error when running this code :-

Code:

CC="gcc -isystem $GCC_INCDIR -isystem /usr/include" \
../configure --prefix=/usr \
--disable-werror \
--enable-kernel=3.2 \
--enable-stack-protector=strong \
libc_cv_slibdir=/lib
unset GCC_INCDIR

The error that i am facing is :-

Quote:

checking if gcc -isystem -isystem /usr/include is sufficient to build libc... yes
checking for nm... nm
checking for python3... no
checking for python... no
configure: error:
*** These critical programs are missing or too old: python
*** Check the INSTALL file for required versions.

Can anybody help me on this?
Thanks in Advance.

Either you don't have Python3 on your host system or your Python3 is too old. The error message tells you what to do. Section 2.2 lists what you need to have on your build host and how to check if you have it.

Oops! I didn't notice that this is a Chapter 6 build. In that case, the Python3 you should be using is the one you built in Chapter 5. The command should be in /tools/bin, which is at the end of your command path if you have chrooted properly.

I have had that same error ( I made a post about it here)

You have made a mistake along the way somewhere. I suggest you do it over again.

I have created a text file with everything I will/have entered for the build so I have it all in front of me, and in sections for easy readibility
Going over it a few times, I have seen some minor problems.

If he simply forgot to build Python3, he can at this stage still recover. Remember, this is the glibc build, so his binutils and gcc are still the unadjusted ones that will correctly build anything in Chapter 5. And the build order in most of Chapter 5 is irrelevant (in practice, things are built in alphabetical order). Whereas in Chapter 6, of course, the correct order is essential.

So this is one of the rare places where you can actually make a correction.
