[Buildroot] LZMA in Buldroot.

[Buildroot] LZMA in Buldroot.

[Thomas Lundquist]

Hi folks.


Since I have patches for lzma compressed initrds (ext2 root filesystem)
I added BR2_PACKAGE_LZMA_HOST and moved the package/lzma/ to
toolchain/lzma and made it just as sstrip.  (and tmake, which I've also
added).

about initrd kernel patches; I've attached one for 2.6.15.4 but if there
are interest I'll maintain patches for newer versions aswell.

I also have patches for lzma compressed kernel but only for i386 (I need it
for ARM but have met some challenges.).

Thanks to Ming-Ching Tiew for making the kernel patches.

I wasn't sure about that myself but sstrip was done like this, so I
moved it.

I have no problems with making a patch that does not move it but why was
sstrip done this way? 

the libraries are done from the package directory but they are the same
in staging and target (except for stripping) but here we are talking
about two sifferent binaries, one compiled for the host and one for the
target.

this was at least my guess on the reason behind putting sstrip in in the
toolchain part.

(my sstrip, or rather elfkickers package, which was never included in
buildroot was in the package directory but then sstrip showed up in
toolchain.)

I've kept building of lzma-host in toolchain since we have to build two
different sets.

patch attached.

We only have to make sure that we don't pickup the wrong objects, that
should be all.

reminds me that we may want to lzma the other filesystems too, later on.

there are patches for lzma compressed squashfs around. I haven't found
any for 3.0 tho.

as snipped out from the original lzma.mk, it's commented out which is
why I removed it.

do you still want it?

Yes, i left it commented out. I had (and still have) trouble with c++
due to an alleged bug with libtool on my ubuntu devel host. Probably i'll
ditch that install and go back to what i usually run as a sensible base
to work on.

Yes, i do and will add it too when i have verified and applied your
diff. No timeframe on checking it, though.

If you find the time to add the rule for the header(s), then i'll
blindly apply your take 3 patch see if i need any additional changes.
I don't know if anybody except me does currently use lzma via buildroot
on their targets, so i do not feel obligued to be exceptionally stable
at that end..

What do you think?

I don't think you're the only one.

BTW; we should have uClibc++ available in buildroot. maybe I'll look at
it. (I haven't seen it, maybe I'm just blind?)

I use LZMA on my target (ARM9 but also floppyfw, which is intel and buld
using a devkit build by buildroot...), so you're not the only one :=)

BTW, I had lzma in buildroot some time ago but I've been using the SDK
directly and not the lzma-utils, which are a derivative. I have to admit
I am a bit unsure if lzma-utils is the right thing altho it's more
compatible option wise. (which could be fixed by a wrapper script).

but now we use lzma-utils and I am digressing alot.

You can, if you want to, wait with applying the patch and I'll verify it 
myself (have to admit I havent after moving it from toolchain to package.) 
and also add the lzma-headers back in.

I think that you are right, there is no uClibc++ in buildroot yet.
Until now, i hesitated to look at adding it since i do not know how
intrusive it is wrt using it for the toolchain..

That would be great, please do so :)

It took me a while to figure out what libtool was for, but one of my coworkers 
explained that the purpose of the thing is to make sure that shared libraries 
work as well on Sun and AIX and Hurd and such as they do on Linux.

You'd think that they'd do this by improving library support on other 
platforms rather than breaking Linux's shared library support (at least if 
you use libtool) until the other platforms don't look so bad in comparison.  
But that's not the FSF way.  In the land of the blind, the one-eyed must have 
that eye poked out in the name of fairness and equality.

There is absolutely no reason to use libtool on Linux, and it regularly breaks 
when you're cross-compiling from Linux to Linux on different processors.

Just to clarify, i'm talking about the gcc internal copy of libtool that
seems to misbehave for me. I'm _not_ using libtool to create a library
for use in buildroot.

I'm sorry, but i now see that i almost forgot to check your patch in.
Applied as r16495, thanks!
