LinuxQuestions.org - [SOLVED] trouble with sed at libstdc++.la

Hello

In book LFS-7.6

"sed 's/tools/usr/' /tools/lib/libstdc++.la > /usr/lib/libstdc++.la"
fails with the message:
"sed: -e expression #1, char 11: unterminated `s' command"

/tools/lib/libstdc++.la

Code:

# libstdc++.la - a libtool library file

# Generated by libtool (GNU libtool 1.3134 2009-11-29) 2.2.7a

#

# Please DO NOT delete this file!

# It is necessary for linking the library.



# The name that we can dlopen(3).

dlname='libstdc++.so.6'



# Names of this library.

# The name of the static archive.

old_library='libstdc++.a'



# Linker flags that can not go in dependency_libs.

inherited_linker_flags=''



# Libraries that this one depends upon.

dependency_libs=' -lm'



# Names of additional weak libraries provided by this library

# Version information for libstdc++.

current=6

age=0

revision=20



# Is this an already installed library?

installed=yes



# Should we warn about portability when linking against -modules?

shouldnotlink=no



# Files to dlopen/dlpreopen

dlopen=''

dlpreopen=''



# Directory that this library needs to be installed in:

libdir='/tools/lib'

/usr/lib/libstdc++.la is an empty file

Where is my fault?
