Hi

Found a similar problem have a look here

esornep · 07-04-2012, 12:19 PM

yeah removed all the build libraries and started from the first but same error ....... and yes viewed the link u posted ............... any help ..... thanks

spiky0011 · 07-04-2012, 01:24 PM

Hi

Did you run the checks at the bottom of glibc

Code:

echo 'main(){}' > dummy.c
$LFS_TGT-gcc dummy.c
readelf -l a.out | grep ': /tools'

And get the correct output

esornep · 07-04-2012, 01:29 PM

yep got the output right ... it is giving the same error on ubuntu 11.04 (using LFS 7.1) any help ???

Did you forget this step (done from within the gcc source directory):

Code:

tar -jxf ../mpfr-3.1.0.tar.bz2
mv -v mpfr-3.1.0 mpfr

One of the build instruction steps: http://www.linuxfromscratch.org/lfs/...gcc-pass2.html

Do remember to completely remove the gcc source and build dir before redoing this chapter!

esornep · 07-04-2012, 01:41 PM

no .. i checked it had the library .... removed everything and started from first but the same error....

druuna · 07-04-2012, 01:51 PM

I noticed you do not use the $LFS/sources directory, why? (make[1]: Leaving directory `/mnt/lfs/gcc-build'). This chapter: http://www.linuxfromscratch.org/lfs/...roduction.html and one related command here: http://www.linuxfromscratch.org/lfs/...ddinguser.html

Please follow the books instructions......

Just in case, can you post the output of the following command:

Code:

ls -l $LFS/gcc-4.7.1/

The GCC documentation recommends building GCC outside of the source directory in a dedicated build directory:

You misunderstood that. It means:

Untar the gcc package in $LFS/sources (as usual), enter the created directory ($LFS/sources/gcc-4.7.1). This is your reference when you start reading the gcc (or any other) chapter. All the commands in a chapter are done from within the package source directory.

Why are all these files and directories owned by strings? You are doing these steps as user lfs and these files and dirs should be owned by lfs.

reread chapter 5.3

Code:

Important

To re-emphasize the build process:

    Place all the sources and patches in a directory that will be accessible from the chroot environment such as /mnt/lfs/sources/. Do not put sources in /mnt/lfs/tools/.

    Change to the sources directory.

    For each package:

        Using the tar program, extract the package to be built. In Chapter 5, ensure you are the lfs user when extracting the package.

        Change to the directory created when the package was extracted.

        Follow the book's instructions for building the package.

        Change back to the sources directory.

        Delete the extracted source directory and any <package>-build directories that were created in the build process unless instructed otherwise.

in other words cd gcc-4.7.1 mkdir ../gcc-build which will make a dir in /mnt/lfs/sources/gcc-build

I did notice the same here http://www.linuxquestions.org/questi...ml#post4718088

esornep · 07-04-2012, 02:37 PM

okay understood never to be smart ...... but can u help me how can i understand all that is going ....... and strings was the name of the user i gave instead of lfs ......

spiky0011 · 07-04-2012, 02:41 PM

Ok

I think you need to rebuild because gcc pass1 is wrong that is why you was having all that trouble. Sorry for the ad news.

Thanks druuna for spotting the mistake You cant beat experiance
