c++ uses system to give commands to bash

hi
I want to use system (or any method that works

to call the following chroot command in bash.

Code:

chroot "$LFS" /tools/bin/env -i \ HOME=/root TERM="$TERM" PS1='\u:\w\$ ' \ PATH=/bin:/usr/bin:/sbin:/usr/sbin:/tools/bin \ /tools/bin/bash --login +h

the 'PS1='\u:\w\$ ' ' gave me lots of problems so i exported it as a variable = $PSNEW

i just cant seem to get the syntax right in c++ to pass the command, i tried plenty of variations and the code below is as correct as i've got . .

Code:

exitStatus = system("chroot \"$LFS\"" 
" /tools/bin/env -i"
" HOME=/root TERM=\"$TERM\" \"$PSNEW\"" 
" PATH=/bin:/usr/bin:/sbin:/usr/sbin:/tools/bin"
" /tools/bin/bash --login +h");

any ideas please ?

Whatever your end goal is with this, there has to be a better way than using c++/system.

What, exactly, is your end goal?

The end goal is simply to create an automated build of LFS, i think you're right, c++ isn't really suited for this.

I'm gonna go use make, i think it'll do the job a lot better
