Hi LinuxQuestions, thanks for resolving my previous question.
But...i have a new question.

I have to unzip the following package in Linux From Scratch:
I try as it says on the official website:
But I get the following error message:
Try it with "j" tiny, and says:
Then I happened to install:
Install it and try to unzip as follows:
but ... flashing dash appears ... and so remains ...

I can do to decompress the tar.xz?

try
Kind regards

Hi , thanks for answering, but...try it with-xvf, and i get:

Hi

I am guessing you are at chapter 5.5?

Have you downloaded GMP to /mnt/lfs/sources?
Then you have to untar gcc-4.61 cd into gcc dir then run the tar command from within the gcc dir.

/mnt/lfs/sources/gcc-4.6.1 then run command tar -jxf ../gmp-5.0.2.tar.bz2.

Gmp-5.0.2 is a bz2
http://ftp.gnu.org/gnu/gmp/gmp-5.0.2.tar.bz2

Ps

I did look at the website and found gmp-5.0.4.bz2
Not sure if it,s a good idea to use it, It might be a good idea to stick to the book

xz is relatively new. Afaik, it is not integrated in the tar command like gzip and bzip2 are.

First decompress the file with the appropriate xz command (I _think_ it's unxz.)

unxz foo.tar.xz

then untar the resulting foo.tar file

tar -xvf foo.tar

This is just a guess, but your posts consistently show that you allow no space between your "tar" command and the options. You installed the proper software, i.e., XZ. Thus "tar -xvf" should now work for everything left in the book. Tar will select the necessary tool for you. If the syntax is wrong, nothing will work. Try again with a space between the "tar" and the "-".

That might work for gz and bz2, depending on the host distro. There are some weird customized tar commands out there. But standard tar requires that the compression type dependant switch (z for gzip and j for bzip2) be given. (I assume you know the x switch is 'extract'). The Xz compression is so new it's unlikely his tar knows about it. Anyway, I just build lfs7.0 and I had the same problem. The only solution I found was the one I gave. Btw, you can do the same with tar.gz and tar.bz2 files, using gunzip and bunzip2 respectively.

XZ support in tar is now 3 years old, but I know some still rely on tar-1.13. I use 2 versions, relying on 1.13 only for pkgtool. My point was really more about syntax than anything.

No problem. I didn't know that the newest versions of tar had Xz support. I'll have to check into that. I don't think that the op was having syntax problems, as I had a very similar experience and I was copy and pasting commands right out of the lfs 7.0 book.

I was using a package of the latest version, I did not realize. Now download the correct version and was able to decompress!
Thank you!
