Compiling Binutils 2.20.1

Hello everybody

I try to compile binutils 2.20.1 with the LFS Manual 6.7. I use a UBUNTU 11.10 as a host system. I use the following configure:

Code:

../binutils-2.20.1/configure --target=$LFS_TGT --prefix=/tools --disable-nls --disable-werror

I get the following error:

First at all i search with help from google if anybody had a similar problem but i couldn't find anything.
Secondly, how can I solve such problems by myself? the config.log file has no further information about the error above. How can I narrow down the problem?
Can anybody give me some advice about the error above?

Greetings

Did you make sure the host system is compliant by running the version check script

I am using the LFS Manual more as a guideline to prepare my own toolchain.

So there are a few problems there these need to be fixed 1st. Apt get can get the packages you require then check version check again restart build fromscratch

you still have some errors in the output.

These need to be fixed

sorry i post the last one too early... i saw that too... at the moment the output looks like this:

The following error "/lib/libc.so.6: No such file or directory" is due to the fact, that the library is under /lib/i386-linux-gnu/libc.so.6. What should I do about that?

I had to make a symlink for it to work on mine

Code:

sudo ln -s /lib/i386-linux-gnu/libc-2.13.so /lib/libc.so.6

Ok now everything is fine with the symlink. But i'm stuck again until I compile the binutils 2.20.1. It is the same error as above. Any further suggestions? The error is mentioning something about that two declarations of malloc are found isn't it? Do I have to exclude a specific path for the make command for further progress?

what is the output of echo $LFS

echo $LFS => /media/lfs

this is another harddrive. The lfs has the /tools & /sources folders.
Just 2 minutes before i tried to compile binutils with the root rights and i did work... something with my lfs user is quite not right... ???

What isz the output of

Code:

ls -l /lib/libc.*

on host system mine is
lrwxrwxrwx 1 root root 32 2011-10-10 19:16 /lib/libc.so.6 -> /lib/i386-linux-gnu/libc-2.13.so

lfs@marius-HP-Pavilion-dv9500-Notebook-PC:~$ ls -l /lib/libc.*
lrwxrwxrwx 1 root root 29 Nov 8 23:15 /lib/libc.so.6 -> /lib/i386-linux-gnu/libc.so.6

The same output as yours.

No yours is different mine points to i386-linux-gnu/libc-2.13.so yours is /libc.so.6. did you pass the version check

yes, i thought that i take the same static library as from the test output:

Code:

I did found the trouble maker...

In the root directory... i had already a /tools folder which had some crap in it. I removed this folder and created a simlink to $LFS/tools. Now it worked.

Thanks for other the help! Hope i get further tomorrow with compiling gcc 4.5.1.
Just as question: I only want to work the CHAPTER 5 of the LFS Manual to get a functional toolchain. After that can I copy the toolchain to a already compiled linux kernel? Will the toolchain be able to compile further tools?

Hi,

Before you start you need to correct this:

The link should point to bash and not dash.

Although I'm not 100% sure what it is you want to do, at the end of chapter 5 there is a caution note (5.35. Changing Ownership - Caution) which indicates that you can re-use the temporary environment. It does assume that this is done to build another LFS system. It also is partially machine depended, the temporary environment does use parts of the host system (the kernel being one).

Hope this helps.

Ok i'll correct that.

Maybe I misunderstand the LFS manual.. I thought that the Toolchain will be prepared that it is host independent. I refer to section 5.2:

Quote:

The overall goal of Chapter 5 is to produce a temporary area that contains a known-good set of tools that can be
isolated from the host system.

My main goal is to prepare the toolchain on my laptop and afterwoods i'd like to copy the toolchain to our embedded device which runs with an ATOM processor (x86). We already compiled a kernel (2.6.39) there. This toolchain should help to compile further tools for the embedded device. The embedded device have enough cpu power so we thought that such a toolchain would be a huge relieve. Is there a main problem in this goal ?

Hi,

That is basically true. But, as you might have noticed, no kernel is installed in chapter 5 (only the API headers are). Once you reach chapter 6 you chroot into the environment you just created in chapter 5. The hosts kernel is still used, but the sane environment is used to build a fully functional LFS (which chapter 5 does not. It is a limited, sane environment).

Quote:

I don't have any experience building LFS/Linux on embedded devices, but the first thing that does come to mind: Are both platforms the same? You mention that the embedded platform is x86, how about the host you are building the temporary environment on? What you are building now is based on the hosts architecture, which might not (or might) be the same as your embedded system.

I do wonder if this is going to work. You might want to keep us updated on your progress, it could be of value for others that want to try this.

Hope this helps.

I will keep you posted to my progress with the toolchain. I approached the section "5.8 Adjusting the Toolchain". Everything else worked well.
The exact kernel version of the embedded device is 2.6.39.1. I downloaded it on my host system into the sources folder. I used this for the section "5.6 Linux-2.6.35.4 API Headers" to expose the API to my kernel version (2.6.39.1).
Further information will follow or further questions will be asked.
