[Buildroot] bash instead of busybox

[Buildroot] bash instead of busybox

[Charles Krinke]

Gentlemen:

I have a request to build a rootfs.jffs2 for an MPC8323 with bash
instead of busybox. So, ... I unset busybox in buildroot's make
xconfig and set bash. Then do a "make clean && make". At the end of
this, I see the two lines from makedevs. And, of course, to make it
worse, after I load it into the flash and boot from it, I do get a
shell of the form "sh-4.1#", so at least the file system boots. I
*think* at this point that a number of packages need to be added
starting with say, "ls" which I *think* is in the fileutils package.

I dont see fileutils as a package option in the buildroot xconfig.

Can someone offer a suggestion or two to a naive programmer to help
find some of the essential packages that are now missing?

I have something similar but did not uncheck busybox.  After bash has
built, it overwrites the /bin/sh symlink to busybox with a (IIRC) hard
link to bash.  That should work for you and keep you from having to
build other packages.

I don't recall, but I may have modified the busybox config to not build
the 'sh' parts, but I do not remember and my git repo is not convenient
at this time.

[Buildroot] bash instead of busybox

[Charles Krinke]

Dear Robin:

I considered that, but am caught in one of the old "the customer says
he doesnt want busybox", so I am trying to find the various packages.
I have gotten some working and am now at the point where the sysvinit
package needs getty. I also havent figured out how to get the
fileutils package into buildroot so I can get things like "ls", but as
I find packages that seem appropriate to buildroot, I can add them and
still boot the rootfilesystem albeit with erros of "cannot execute"
here and there.

Charles

As you have found, the buildroot rfs is conventionally used with busybox 
for most of the common utilities, you may want to push back on the 
customer requirement of "no busybox" and get clarification on whether 
they truly want it completely purged or just wanted bash for their shell.

You want coreutils for ls & friends.
Probably also util-linux for mount and other friends.
Sysvinit for some nice init otherwise you'll have a hard time too.
There are other packages you might want too, like some dev manager now 
that you'll lack mdev, udev maybe? Or a static /dev tree.
You see, if they really don't want busybox the filesystem footprint 
will grow considerably, maybe that's not an issue.
If it's a license thing, well, good luck, most of the other tools 
busybox replaces are GPL too.
Regards.
