LFS 6.8: Problem in Sanity Check in Chroot (chap 6.10)


I've just installed the first three packages after getting into the chroot (which are the kernel, man pages, and glibc). Then completed re-adjusting the chainlink.
The problem is when I try the sanity check, the cc dummy.c -v -Wl,--verbose &> dummy.log command, to be exact. This command doesn't seem to be creating any 'a.out' file as the book says. This can be shown as when I run the readelf -l a.out | grep ': /lib' command, the output is:
Code:
readelf: Error: 'a.out: No such file
What confuses me more is that when I run just the cc dummy.c command without the rest, it seems to be working normally.
Anyone got solution or the same matter? Thx

Hi,

Info generated during the compilation is inside dummy.log. Did you notice anything interesting?

oh, yes! I notice that there is this message:
Code:
collect2: ld returned 1 exit status
Does this mean anything? Thanks!

This only shows an error occurred, not which one. That info should also be in the before mentioned log file. If you cannot find/determine the error, post the complete contents of dummy.log.

Hope this helps.

I do notice that there are some error, though I don't really understand, mostly are related to the 'ld'.

Hi,

You made a typo:
Code:
/tools/lib/gcc/i686-pc-linux-gnu/4.5.2/../../../../i686-pc-linux-gnu/bin/ld: unrecognized option '--verbrose'
That should be --verbose and not --verbrose

Hope this helps.

yeah, that helps quite a lot; but still not generating the a.out file.
thanks, though

Then you need to recheck the new dummy.log file, it should have gone one (or more) steps further and show a new error.

Hi,

looking at the above output I see some success entries on /tools/lib/...... which is very suspicious.

The point of the 6.10. Re-adjusting the Toolchain chapter is to switch back from /tools/lib to /lib (and /tools/lib to /usr/lib). I can only assume that something went wrong with one of the previous 2 steps (probably the gcc -dumpspecs | sed -e .... step).

Hope this helps.

Hey, I think you're right! The problem seems to be that I forgot to put a symlink.

So then, the case is closed!
Conclusion: misspelling, missing symlink
Moral story: be more careful!

I don't know if i could start a new thread but i'm having the same problem here and i issued the commands of the book correctly...

The thing is i can't post the dummy.log here because i'm using the live cd on that particular machine , if anyone could tell me how to do it i'd like that

Inside dummy.log certain libs are unable to open such as libgcc_s.so and libgcc_s.a and in the end error messages appear

ld : cannot find -lggc_s
ld : cannot find -lc


i would appreciate any help i'm stuck here...
thanks in advance!

@eliadk: Hi and welcome to LQ

If the information given in the above answers doesn't help: Please start a new thread, this one has the SOLVED status.

When you do start a new thread provide the following information:

- Which LFS version are you trying to build,
- Which chapter are you working on,
- Which step and what is the exact error message.

You do mention you cannot post the dummy.log, but we do need exact messages in order to help you. Can't you put the log file on a USB stick?

Hope this helps.
