 |

Hello,
I try to compile the glibc-2.6.1, but i have an error and i don't find any solution:
| Code: | ...
bcopy.c:21:1: warning: "memmove" redefined

Yes, but first you need to post more of the output, just as it says "post the topmost error".
It means scroll up using shift+pgup to Error 1 and post from a few lines above that all the way to the bottom.
If you have difficulty with copy/paste, then you can use the following method:
Take a note of the location of the location of the complete build.log of the failed glibc emerge, then run: | Code: | emerge wgetpaste
wgetpaste <path-to-build.log> |
And also post the output of this please:
Like this: | Code: | | emerge --info | wgetpaste |
Then paste the URLs here, and we'll have a look.

| Is there a reason you are trying to build glibc-2.6.1 (which is very old at this point)? The error you might be facing is because it won't compile with more modern versions of gcc, etc. |

Oops, missed that, thanks mikegpitt. 
Just post your emerge --info then. |

| Downgrading glibc will kill your system. Better tell us what are you trying to achieve? |

But when i've done the 'emerge --info', I had to remove an option behind the cflags. I had previously:
| Code: |
CFLAGS="-o2 -d_fortify_source=2 -march=i686 -pipe" ../glibc-2.6.1/configure --prefix=/usr
|
| Jaglover wrote: | | Downgrading glibc will kill your system. Better tell us what are you trying to achieve? |
I don't try to downgrading glibc, I'm trying to create a minimal system based on gentoo, so I downloaded the kernel, etc., and so I have to compile glibc to put on my new system. The idea is to create uen gentoo bootable image on a USB key.
To create this, I previously installed the latest gentoo in order to use the compiler, fdisk, etc..
Thank you for your help |

That's -O2 (uppercase o), -o2 is something completely different that you don't want in your CFLAGS. And what did you try to accomplish with the configure command in make.conf? |

So basically you installed a Gentoo system, and you are trying to build a minimal environment inside a chroot jail, correct? I'm still not exactly sure why you would be using an old version of glibc instead of using all the latest stable packages. I apologize for not answering your question, but I think it's a good idea to first ensure you are trying to build your environment in the most sane way possible. |

I will try with an upper O. To be honest, I do not understand why I have to put ' ../glibc-2.6.1/configure --prefix=/usr ' behind the CFLAGS, but it was recommended to me by the teacher. I searched and I realized that the file which I referred, I must call previously with this option before typing the command 'make'

The version of glibc was given to me by Professor |

What your trying to do is use gentoo to build a "Linux From Scratch" system. For info "emerge linuxfromscratch" which is the bible for doing something like this.

You are right... this is nonsense. If you want to run configure options on a package, the proper place to do this is inside the ebuild. From the look of where glibc installs it assumes the prefix /usr by default.
Now that you mention that a professor wants you to do this everything makes sense... professors never know what they are doing 
Without understanding more about your project I don't understand why you are doing things the way you are, but I'm guessing that your prof gave you an older snapshot of a bunch of packages which would be compatible with each other... is that true? If not, I would ask your professor if you need to do things with his exact packages, or if you can just move to their modern equivalents. The latter option will give you less headaches, but might defeat the purpose of your project. |

I find on a french web site (http://www.fr.linuxfromscratch.org/view/clfs-1.1-fr/x86_64-64/final-system/glibc.html)
equivalent parameters for CFLAGS ...
| Code: |
CFLAGS="-mtune=generic -g -O2" \
../glibc-2.7/configure --prefix=/usr \
--disable-profile --enable-add-ons --enable-kernel=2.6.0 \
--libexecdir=/usr/lib/glibc --libdir=/usr/lib
|
The problem is that the author of the tutorial does not seem reachable .... Can you watch?
In advance thank you

Your post should goes to unsupport software as it's about linuxfromscratch and not installing gentoo.
What you've done wrong is that they told you
| Quote: | CFLAGS="-mtune=generic -g -O2" \
../glibc-2.7/configure --prefix=/usr \
--disable-profile --enable-add-ons --enable-kernel=2.6.0 \
--libexecdir=/usr/lib/glibc --libdir=/usr/lib
|
The \ are there because for long lines to type, you just end the line with \ and keep writing your long line and last time you will hit the enter key without an ending \ the whole line will be taken as
| Code: |
echo this \
is a stupid \
example
|
you should type it as : echo this \[return key push] is a stupid \[return key push]example[return key push]
and gave you result :
| Code: | | this is a stupid example |
If you understood it, it's exactly the same as "echo this is a stupid example" but easier to read if you have a real long line to show or type
So that command is not to set your CFLAGS as-is, but it's one to be type & execute.
The purpose is to run the configure script of your glibc (the ../glibc-2.7/configure program) while CFLAGS is set to some values so the program will run with that CFLAGS in its context.
As example check your cflags value if you type that
| Code: | | CFLAGS="this is a stupid example" emerge --info |
as you'll see CFLAGS will be report as "this is a stupid example" but if you rerun "emerge --info" you'll see your cflags will be normal (well, as it should in its normal context)
Same for the parameters pass to glibc configure (--prefix=/usr)... for linuxfromscratch point of view i suppose their tools aren't yet in /usr to build the distro, so it's necessary to told the configure script where the final product should goes.
If you want to do like them you need to download the glibc version source file and unpack it by hands and follow what they said, but you can't emerge glibc like that.
You might just emerge -f glibcverisonyouwish" to ask gentoo to download the source file and pickup the file from your distfiles directory.
But as you seems really to lack knowledge for doing something like that, i suggest you 1/ use a linuxfromscratch and follow their instructions blindly or 2/ gave up and explain your teacher you shouldn't sleep in class or 3/ if you want cross compling with gentoo that doc might help http://www.gentoo.org/doc/en/cross-compiling-distcc.xml (it's about cross compilation in gentoo WITH DISTCC, but you'll find the info about crossdev tools and howto build a glibc for another arch) or just emerge crossdev and read the doc or google for it |

I don't know for glibc, but every package I have ever had the unfortune to be forced to compile manually, defaulted to "/usr/local" as the prefix, so normal users are able to install a local system without being root. (If the system administrator allowed them to install into /usr/local of course.)
So from that point prefixing to /usr surely makes sense.
