Hi,

I'm not able to find what the problem might be with the above info.

A few pointers/questions:

- Did you remove the gcc source and build dir before starting with pass 2 (the leftovers from pass 1). You should.
- Are you sure you did not make any mistakes with the given commands in chapter 5.10 (copy/paste those if at all possible).
- Did you unpack the GMP, MPFR and MPC packages in the gcc source directory (and _not_ the gcc-build directory).

I would suggest removing the source and build dir and try chapter 5.10 from the beginning.

Hope this helps.

hi,
1. Yes I did.
2. Actually rather than typing, I use shell script and pasted below. My PC is i686 32 bit so 64bit operations are omitted. I compared with book and didn't found any difference.
3. Yes.

Thanks for any further help!

Hi,

If this is your first LFS build I would strongly suggest not using scripts. Especially the one in post #3!! I do not see _any_ error checking whatsoever on the successful completion of the commands, if one of the commands fails, the script will keep running and you won't have any idea what will happen in that scenario. The LFS book does contain the occasional mistake (wrong version number, tarring a tar.gz instead of a tar.bz2 file etc).

If at all possible copy and paste the individual sections. If all is ok, do the next section.

I also noticed the following: You are building gcc 4.5.1, the 6.7 stable book points to gcc 4.5.2.......

I can only assume you also used scripts for the previous parts, which makes it all but impossible to determine if and where things could have gone wrong.

2 questions:

- What does the LFS_TGT variable hold?
- What file-system are you building LFS on?

hi

As I am building lfs, the current stable version move on to 6.8, which will build gcc 4.5.2. The 6.7 version still points to gcc 4.5.1

reply to your questions
1. LFS_TGT=i686-lfs-linux-gnu
2. the file system is ext3 type, i followed lfs book to create a separate partition and format it to ext3, then mount it.

I understand your points about scripts. Yes I created all scripts and run them by
bash gcc2.sh 2> errlog

and check the errlog and try to save the typing and typo error when I have to do it multiple times.

Anyway I will have to try to remake the gcc 4.5.1 pass 2 by typing and typing...
