Made it to Binutils building

spiky0011 · 01-29-2011, 11:22 AM

I,m confused, I have unpacked lfs packages 6.7 to sources directory, I have untar binutils ok. It created it's own directory as stated in book, opened the README Do I run ./confiure from within sources/binutils folder, OR as The book sayes outside sources folder

Code:

It is important that Binutils be the first package compiled because both Glibc and GCC perform various tests on the
available linker and assembler to determine which of their own features to enable.
The Binutils documentation recommends building Binutils outside of the source directory in a dedicated build
directory:

Code:

mkdir -v ../binutils-build
cd ../binutils-build

Hi,

The book always assumes that you are standing in the unpacked directory ($LFS/sources/binutils-2.20.1 in the above case).

The following is executed from that directory:

Code:

mkdir -v ../binutils-build
cd ../binutils-build

And the reason why is this:

Code:

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

The actual binutils sources are stored here: $LFS/sources/binutils-2.20.1 and all the work is done from here: $LFS/sources/binutils-build

Hope this helps.

HaHA I see my mistake it was the ../ that I missed I am not 100% in terminal can you tell, but i.m finding this very interesting.

1 Question is it safe to shutdown at any time whilst not building? Then do you log back in to user and just carry on building where you left off

druuna · 01-29-2011, 02:42 PM

Hi,

Yes, you can shut-down and continue later on.

You do have to remount $LFS and become user lfs first before you continue (talking about chapter 5). Once you arrive at chapter 6 other things need to be done, but lets get there first

Hope this helps.

I,m having problems with 5.5.1 I,ve come up with errors so I deleted gcc-build and started again

druuna · 01-29-2011, 03:31 PM

Hi,

Make sure that the source-dir and build-dir are clean before you start again.

Easiest way to do this: Remove them and restart with unpacking the tar file(s).

The error i get is

Code:

errors in '/mnt/lfs/sources/gcc-build/i686-lfs-linux-gnu/libgcc

this is during Make process.

Code:

configure-target-libgcc

error1

Ok if I shutdown I remount lfs ok but I cant login as user lfs unless I carry out section 4.3 again? Also I have 2 colouered prompts as lfs a "green 1" or a "white 1 it changes to white when

Code:

source ~/.bash_profile

You need to post more information, the above won't tell us what went possibly wrong.

If an error occurs that you cannot fix yourself post at least the last 10 lines (Have a look at this chapter, especially 1.5.3).

Are you using the LFS liveCD as hosts? If so you need to recreate the lfs user (I.e: chap. 4.3 and 4.4). If you use another distro as host (which I do suspect): The lfs user should already exist...

The change in colouring isn't important, although it does show you that the .bash_profile file is parsed.

Hope this helps.

This is the error I get from make gcc-4.5.1 pass1

Code:

-TLS _o bid_decimal_globals.o -MT bid_decimal_globals.o -MD -MP -MF bid decimal_globals.dep -c ../ ../gcc-4.5.1/libgcc/config/libbid/bid_decimal_globals.c ../ ../gcc-4.5.1/libgcc/config/libbid_decimal_globals.c:47:18 fatal error: fenv.h No such file or directory
compilation terminated.
make[2]: ***[bid_decimal_globals.o] Error 1
make[2]: Leaving directory '/mnt/lfs/sources/gcc-build/i686-lfs-linux-gnu/libgcc '

make[1]: *** [all-target-libgcc] Error 2
make[1]: Leaving direcyory '/mnt/lfs/sources/gcc-build'
make[2]: *** [all] Error 2

I did start again from a fresh install, I am using lfs live cd 6.3 as host with book 6.7 and sources 6.7.
I hope this is enough information

Hi,

what was the exact configure command that you issued? I am just taking a guess here, but did you use the '--disable-decimal-float' switch? The header 'fenv.h' stands for floating point environment. So I would start checking the corresponding switch. Also double check if mpfr etc. was extracted in the correct directory, i.e. inside gcc's source directory, not the build directory.

Thks crts You pointed me in the right direction it was as simple as a spelling mistake, I have ran make & make install all good. I,m at 5.6. Linux-2.6.35.4 API Headers. The first code

Code:

make mrproper

as it sayes will clean up but in which directory I take it I dont want to run that at lfs:/mnt/sources/gcc-build$ or do I untar the linux-2.6.35.4.tar first? The book dosn,t tell you to go anywhere

spiky0011 · 01-30-2011, 10:34 AM

Have done last part with no errors thks to google,

Hi,

Just in case (and for other searchers):

This is a bit unclear in the book, although there is a hint in the title of that chapter.

You indeed need to unpack the linux kernel package and enter that directory, all the header commands are executed from here.
