Before Gzip is installed, the patch file may need to be applied. This patch file is necessary to avoid a conflict of variable names with Glibc-2.0 systems when compiling and linking statically and so is only required if your base system runs Glibc-2.0. It is however safe to apply the patch even if you are running a different glibc version, so if you aren't sure, it's best to apply it.
Apply the patch by running the following command:
patch -Np1 -i ../gzip-1.2.4a.patch
Install Gzip by running the following commands:
./configure --prefix=$LFS/usr && make LDFLAGS=-static && make install && cp $LFS/usr/bin/gunzip $LFS/usr/bin/gzip $LFS/bin && rm $LFS/usr/bin/gunzip $LFS/usr/bin/gzip |
The Gzip package contains the compress, gunzip, gzexe, gzip, uncompress, zcat, zcmp, zdiff, zforce, zgrep, zmore and znew programs.
gunzip decompresses files that are compressed with gzip.
gzexe allows you to compress executables in place and have them automatically uncompress and execute when they are run (at a penalty in performance).
gzip reduces the size of the named files using Lempel-Ziv coding (LZ77).
zcat uncompresses either a list of files on the command line or its standard input and writes the uncompressed data on standard output
zcmp invokes the cmp program on compressed files.
zdiff invokes the diff program on compressed files.
zforce forces a .gz extension on all gzip files so that gzip will not compress them twice. This can be useful for files with names truncated after a file transfer.
zgrep invokes the grep program on compressed files.
zmore is a filter which allows examination of compressed or plain text files one screen at a time on a soft-copy terminal (similar to the more program).
znew re-compresses files from .Z (compress) format to .gz (gzip) format.
