[Buildroot] "make menuconfig" possibly broken in git master

[Bjørn Forsman]

Hi all,

My buildroot git master tree fails to "make menuconfig" because of
"zconf.tab.c:181: error: conflicting types for ?symbol_hash?":

Is anyone else seeing this?

I "git bisected'ed" until I found the bad commit:

commit 52a142a6314905422f14f05fccafdce35bea7f08
Author: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
Date:   Sat Aug 21 17:00:49 2010 +0200

    Bump package/config to 2.6.36-rc1

    The goal is to be able to use savedefconfig to generate minimal
    defconfig files.

    Four of our patches are removed since the modifications have been
    merged upstream. The new nconf configuration utility has appeared.

I briefly looked at the commit diff but I didn't understand what
caused the breakage.
Any suggestions?

Best regards,
Bj?rn Forsman

Strange - Could you try the the same with a recent linux kernel
(E.G. 2.6.36-rc5)?

I had this too. You have to clean your repository well.

[Buildroot] "make menuconfig" possibly broken in git master

As the commands "make distclean && make defconfig/menuconfig" fail
I don't know how to specify another kernel version. So I assume you mean
the kernel on build host. I'm on Ubuntu 10.04 and the last time I tried my
own kernel on a Ubuntu system it barely booted. So no, I dare not try a
recent kernel just yet :-)

No, I actually meant go and download a Linux kernel tarball (E.G. from
kernel.org), extract it and run make menuconfig. The menuconfig stuff in
buildroot comes from the Linux kernel.

But looking at Lionel's mail it seems to be an issue about certain files
not getting rebuilt. Could you do a fresh git clone and try in that dir
or alternatively run make O=output2 menuconfig?

You are correct. "make distclean" apparently doesn't clean the
repository enough,
because it wasn't until I did a fresh git clone that the issue went away.

Oh, I see :-)

I tried a fresh git clone and it worked fine.

I think I've found the exact issue: package/config/zconf.tab.c wasn't
being rebuilt.
I removed that file, it got rebuilt and the issue was gone.
I think 'make distclean' should clean package/config/zconf.tab.c (and
all *.o files in
package/config/) or this issue may appear next time package/config/ is
synced with upstream.

The distclean does clean everything currently used, but the problem is
that these files used to exist in package/config, but are now in
output/build/buildroot-config, and the original makefile gets a bit
confused when there's old files in package/config.

Ok, so it's already fixed. Good :-)
