Installation of cpio

Install cpio by running the following commands:

sed -i "s/invalid_arg/argmatch_invalid/" src/mt.c &&
patch -Np1 -i ../cpio-2.6-security_fixes-1.patch &&
./configure CPIO_MT_PROG=mt --prefix=/usr \
    --bindir=/bin --libexecdir=/tmp \
    --with-rmt=/usr/sbin/rmt &&
echo "#define HAVE_SETLOCALE 1" >> config.h &&
echo "#define HAVE_LSTAT 1" >> config.h &&

If you have teTeX-3.0 installed and wish to create alternate forms of the documentation, issue the any or all of the following commands:

make -C doc pdf &&
make -C doc ps &&
texi2html -o doc/cpio.html doc/cpio.texi &&
makeinfo --plaintext -o doc/cpio.txt doc/cpio.texi

To test the results, issue:

sed -i 's/static const char/const char/' tests/genfile.c &&
make check

Now, as the root user:

make install

If you built any of the alternate forms of documentation, install it by issuing the following commands as the root user:

install -v -m755 -d /usr/share/doc/cpio-2.6 &&
install -v -m644 doc/cpio.{pdf,ps,dvi,html,txt} \

Command Explanations

sed -i "s/invalid_arg/argmatch_invalid/" src/mt.c: This command fixes a build problem with the mt program.

CPIO_MT_PROG=mt: This parameter forces the building and installation of the mt program.

--bindir=/bin: This parameter installs cpio to /bin instead of /usr/bin as recommended by the FHS guidelines.

--libexecdir=/tmp: This parameter is used so that /usr/libexec is not created.

--with-rmt=/usr/sbin/rmt: This parameter inhibits building the rmt program as it is already installed by the Tar package in LFS.

echo "#define HAVE_SETLOCALE 1" >> config.h: This command specifies that the system Libc implements the setlocale function since it is not detected by configure.

echo "#define HAVE_LSTAT 1" >> config.h: This define fixes a bug that causes cpio to convert symlinks into regular files during archive creation.

sed -i 's/static const ...: This command fixes a build problem when compiling the tests with GCC-4.0.3.
