Hello Friends,

I am trying to compile my LFS using RHEL 5, so when i try to compile the glibc the make command throws the following error :

/mnt/lfs/build/glibc-build/glibc-2.8-20080929/nscd/nscd_helper.c:406: undefined reference to `__sync_val_compare_and_swap_4'
/mnt/lfs/build/libc_pic.os: In function `*__GI___libc_freeres':

collect2: ld returned 1 exit status
make[1]: *** [/mnt/lfs/build/libc.so] Error 1
make[1]: Leaving directory `/mnt/lfs/build/glibc-build/glibc-2.8-20080929'
make: *** [all] Error 2

Friends would really appreciate your help.

Hi,

Please give us the info needed:

- which LFS are you trying to build,
- which chapter (5 or 6),
- is RHEL 5 suitable as base for LFS,
- did the previous steps build without problems.

Hello drunna,

appreciate ur quick response below is my answer for ur questions :

- which LFS are you trying to build,
Am not sure abt this question but am using LFS book ver 6.4 and using rhel 5 as a host OS not using livecd.

- which chapter (5 or 6),
its for chapter 5 section 5.7. Glibc-2.8-20080929.

- is RHEL 5 suitable as base for LFS,
I think it should be it does below is a line from LFS book :

"The LFS system will be built by using a previously installed Linux distribution (such as Debian, Mandriva, Red Hat, or
SUSE)."

- did the previous steps build without problems
Yes i was able to complete following sections in the book :

5.4. Binutils-2.18 - Pass 1
5.5. GCC-4.3.2 - Pass 1
5.6. Linux-2.6.27.4 API Headers

But am stuck on this section 5.7.

Youe help will be appreciated.

Thanks
Sammy

Hi,

First of all: Use regular english, not text/sms/whatever speak! It's annoying and not needed, your not limited to 140 chars per message.....

I hope you also use the packets that belong to 6.4 (did you use chapter 3.2 to download all?).
Before you continue make sure you have the correct package versions that go with the book version you are using.

So I can safely assume that you did not do chapter iv. Host System Requirements......
Make sure rhel is suitable before you continue.

Another thing I noticed: The LFS books suggest using $LFS/sources for storage and starting point for the builds. Is there a particular reason you use $LFS/build?

Hello drunna,

I apologies for my language will ensure in future.

Coming back to the issue here below is my answer :

I did download all the packages and patches from the links mentioned in the book 6.4 and even patched it with the one mentioned in the book and they are the version mentioned in the book.

And as per the book my rhel is perfect because the only thing they have mentioned is RHEL is suitable host OS provided you install all development packages during installation of it please check the line from the book and i have done complete installation of the OS :

"The LFS system will be built by using a previously installed Linux distribution (such as Debian, Mandriva, Red Hat, or
SUSE). This existing Linux system (the host) will be used as a starting point to provide necessary programs, including
a compiler, linker, and shell, to build the new system. Select the “development” option during the distribution
installation to be able to access these tools."

And there is no specific reason to use $LFS/build directory what i believe according to the book is that we can use any build directory so i just created that one for me for easier understanding what i thought $LFS/sources is used to keep all the packages and patches.

Please correct me if am wrong as i am a newbie for Linux.

Again appreciate your help buddy.

Thanks
Sammy

Hi again,

Did or did you not check all the packages mentioned in iv. Host System Requirements? I still think you did not and you should.

In general just about all the distro's are basically suitable as base for LFS. But... some need extra packages, some packet versions are incorrect (too low or too high) etc etc.

The $LFS/build dir is ok, as long as it is a choice by you.

Hello drunna,

issue is fixed once i used the $LFS/sources as the build directory issue is resolved.

it was my fault i did not read it properly again thanks for your help and support.

Thanks
Sammy
