[SOLVED] compiling gcc-4.9.1 failed

michanux · 01-03-2015, 01:37 PM

Hello
on debian wheezy as root I start to install a LFS. For help I use LFS book. But gcc failed with this message:

Code:

checking for C compiler default output file name... 
configure: error: in `/lfs/gcc-builds/gcc-4.9.1/host-i686-pc-linux-gnu/lto-plugin':
configure: error: C compiler cannot create executables
See `config.log' for more details.
make[2]: *** [configure-stage2-lto-plugin] Fehler 77
make[2]: Leaving directory `/lfs/gcc-builds/gcc-4.9.1'
make[1]: *** [stage2-bubble] Fehler 2
make[1]: Leaving directory `/lfs/gcc-builds/gcc-4.9.1'
make: *** [all] Fehler 2

Wheezy has the path:

Code:

/usr/lib/gcc/i486-linux-gnu/4.7/liblto_plugin.so.0.0.0

There is no description of the break in config.log

What was going wrong?

I thing your gcc toolchain is not installed fully. Try compiling a dummy c file. Have you installed gcc, binutils and it's devel packages.

Keith Hedger · 01-04-2015, 08:14 AM

To start off, what chapter are you on?, what is the output of the version script?
If you are building the tool chain you should NOT be using root, as per the instructions in the LFS book.

This:

Code:

..configure: error: in `/lfs/gcc-builds/gcc-4.9.1/host-i686-pc-linux-gnu/lto-plugin':...

Looks like you are in the wrong directory, if you have been following the book you should be somewhere like /mnt/lfs/sources/gcc-build.

What configure/make options are you using? have you deviated from the LFS book in ANY way?

Please supply some more info otherwise we can't really help much except with general advice.

Login as user the compiling of binutils-2.24 failed too.

Code:

It was created by configure, which was

The path is

Code:

/mnt/lfs/binutils-build/binutils-2.24

I use LFS Book Chapter 5.4.1
There is a link from /bin/sh --> /bin/bash

Hi

You should be in dir binutils-build when you run the commands.

Code:

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

If you untar the source package then cd in unpacked dir then follow book

michanux · 01-06-2015, 02:32 PM

Sorry I don't understand your answer. Should I build the path:

Code:

/binutils-build/binutils-2.24

or

Code:

mnt/lfs/sources/binutils-build/binutils-2.24

spiky0011 · 01-06-2015, 03:11 PM

Hi

You should be in /mnt/lfs/sources/binutils-build, Then follow the book

re read chapter 5.3 the last "IMPOPRTANT NOTE"

start off in /mnt/lfs/sources
untar binutils-2.24.tar.bz2
cd into binutils-2.24 (untared directory)
then follow book

michanux · 01-09-2015, 02:02 PM

I changed the directionary but the mistake did not disappear. So I think it is not caused by a missing file because in the root mode the compiling runs well.

spiky0011 · 01-09-2015, 02:24 PM

Hi

Can you post the output of the version script from the book you are using.

michanux · 01-10-2015, 12:06 PM

Hello,
the recommendation of the book version 7.6 is binutils-2.24.

Hi, Checks your processor is 32bit or 64bit.
In my case I had to switch from a Debian 7.7 i386 for a Debian 7.8 x86-64.

michanux · 02-01-2015, 10:54 AM

Okay I started to install LFS from the beginning. In the book version 7.6 GCC-4.9.1 -(Pass 1) on page 38 is a for-do operation searching for "gcc/config/linux.h". But the path on Wheezy is "/usr/lib/i486-linux-gnu/4.7/plugin/include/config/linux.h". Should I replace the path or do I misunderstand the meaning?

Keith Hedger · 02-01-2015, 11:01 AM

By the time you run the for loop you should be in the gcc-4.9.1 folder ( /mnt/lfs/sources/gcc-4.9.1 probably ) the path to the find command does not start with a foward slash so is a relative path not absolute so find gcc/config would be, with the above path would be /mnt/lfs/sources/gcc-4.9.1/gcc/config.

michanux · 02-07-2015, 10:24 AM

Now I am on page 41 of "Linux from Scratch". It deals of installing the API Headers. I am confused about the steps to do. First I extract linux-3.16.2 into "/mnt/lfs/sources/linux-3.2.16" and changed into this path. Should I start with "make menuconfig" than "make" and "make mproper" and and at last "make INSTALL_HDR_PATH....." ?
