[Yann E. MORIN]

From: "Yann E. MORIN" <yann.morin.1998@free.fr>

Instead of over-writing the nsswitch.conf file (which may already
contain user's specific configuration if it comes from a rootfs
overlay, or a custom skeleton), just replace the 'hosts' line.

Remove now-useless custom nsswitch.conf file.

[Buildroot] [PATCH 4/4] toolchain: instrument external toolchain wrapper

[Thomas Petazzoni]

Dear Yann E. MORIN,

I like the feature, but it would be nice if the coding was more
consistent with the rest of the code, see below:

Dirro.

Variable declaration in the middle of the code. I know it's C99 ok, but
I'd prefer not to have that (just like the kernel).

Ditto space before ).

Sure! :-)

It initially was a quick'n'dirty hack, and I eventually thought it might
be useful upstream too. I'll re-read my code better next time... :-/

Doh. Right.

gcc also whines about this (which was my original code):
	for( int i=0; args[i]; i++ ) {

> > +		for( i=0; args[i]; i++ ) {
> 		for (i = 0; args[i]; i++)

Ack.

Atta! I'll fix and respin. Thanks! :-)

It's only an issue for custom skeletons, not overlays as they are only
added after all the packages are built.

That's still not really the code style used elsewhere in this file.

You could argue that this feature isn't really needed as you can just
run 'strace -s 1000 -e execve <wrapper>' for basically the same
information, but OK - This is perhaps a bit more user friendly.

With that in mind, I think a more sensible output format is something
you can directly cut'n'paste and execute in the shell (after perhaps
tweaking something), so I've changed it to simply print the args space
seperated like this:

BR_DEBUG_WRAPPER=1 ./output/host/usr/bin/arm-none-linux-gnueabi-gcc --version

Doh. What happenned? I've just looked at my tree here, adn the style
fixes are applied.

OK. All sorted. I did 'git commit --amend'. I should forgot to pass '-a'
also (or run 'git add' first).

Doh, too bad. Sorry for the inconvenience... :-(

My use-case was to see how the kernel build-system was calling the
wrapper. So I just ran:
    BR_DEBUG_WRAPPER=1 make
in my Buildroot build dir.

Yet, one of the motivation behind the \n-separated args was to easily

The Linux kernel is passing something like 40+ args to the wrapper, so
the line is getting rather long, and difficult to grok visually, while
the one-arg per line output made it very easy.

But OK, that's sane, too.

> Committed with these changes, thanks.

Again, sorry for the inconvenience. :-(

I already owed you one ${BEVERAGE} in Edimburgh; you can make that two,
now! ;-)

So you are only interested in the arguments to the wrapper, or do you
want to see the final arguments to the real compiler?

Ok, but a kernel build with 40+ lines per gcc invocation is presumably
also quite overwhelming?

No, I'm interested in the final, complete argv[*].
