I am praticing LFS 5.5, compile gcc for the fist time.
But got the following errors:
configure: error: in `/mnt/lfs/sources/gcc-build/i686-lfs-linux-gnu/libatomic':
configure: error: C compiler cannot create executables
See `config.log' for more details.
make[1]: *** [configure-target-libatomic] Error 1
make[1]: Leaving directory `/mnt/lfs/sources/gcc-build'
make: *** [all] Error 2

The config.log is :

I have configure gcc successfully by the following cmd:
../gcc-4.8.1/configure \
--target=$LFS_TGT \
--prefix=/tools \
--with-sysroot=$LFS \
--with-newlib \
--without-headers \
--with-local-prefix=/tools \

Is there anything wrong with my enironment?
B.R.

First, if its any consolation, this is a well crafted problem report providing a wealth of good information that I took the liberty of trimming. It's very specific and the title is appropriate.

My initial thoughts are:

1). Double check that you're functioning in the role of the LFS user.

2). Since the start and end object files (crt?.o) aren't found, examine your host system to ensure they're present. Typically they'll be in one of /lib, lib32 or /lib64. Use the command locate crt1.o to identify their presence. Likewise locate libc.so should be executed to verify that the C library is available to the linker.

3). Can I presume that 5.4. Binutils-2.23.2 - Pass 1 yielded no errors?

$ locale crt1.o : EDIT ..
EDIT typo to : $ locate crt1.o : /usr/lib/i386-linux-gnu/crt1.o
$ dpkg -L libc6-dev | grep crt1.o : /usr/lib/i386-linux-gnu/crt1.o
-lc : That's libc.so : Same location.

I.e. Debian / Ubuntu are now now using "a hideaway location" for a lot of files.

Configuring gcc can be like :

$ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/i386-linux-gnu/ && ../gcc-4.8.1/configure -- .......

@knudfl: That info might come in handy!

BTW: Typo -> locale crt1.o should be locate crt1.o has been fixed

Thanks for all your replies.
But I get the same problem after I doing the following action.
Yet, I totoally clean my envirmont and repeat the binutils compiling again, but it doesn't work.

Is there any other solutions?

The bold/red parts look suspicious.

The g++ part shouldn't be there, and looking at the compilation part it seems to be using g++ instead of gcc.

I'm not sure what you did to make Ubuntu 12.04 compliant, but you might have done something wrong. Maybe this will help (specifically the Preparing Ubuntu steps):
- LFS 7.1 on Ubuntu 12.04

BTW: knudfl's post deals with the latest Debian/Ubuntu versions, which would not include Ubuntu 12.04 (which you can check yourself).

Thanks for you help. Following the steps in your blog, I have successfully compiled gcc pass 1.

You're welcome
