The following patch fixes this behavior for all architectures: patch -Np1 -i ../&coreutils-uname-patch; The following command updates the timestamps on the uname and hostname man pages so that the Makefile does not attempt to regenerate them: touch man/uname.1 man/hostname.1 Coreutils attempts to use the install program it just built to perform the install. This will not work if the target architecture is incompatible with the host architecture. The following command causes the Makefile to use the host's install to perform the install: cp -v src/Makefile.in{,.orig} sed -e "/binPROGRAMS_INSTALL=/s:./ginstall:install:" src/Makefile.in.orig > src/Makefile.in Configure can not properly determine how to get free space when cross-compiling - as a result, the df program will not be built. Add the following entry to config.cache to correct this: cat > config.cache << EOF fu_cv_sys_stat_statfs2_bsize=yes gl_cv_func_mbrtowc_incomplete_state=yes gl_cv_func_mbrtowc_nul_retval=yes gl_cv_func_mbrtowc_null_arg=yes gl_cv_func_mbrtowc_retval=yes gl_cv_func_btowc_eof=yes gl_cv_func_wcrtomb_retval=yes gl_cv_func_wctob_works=yes EOF Now prepare Coreutils for compilation: ./configure --build=${CLFS_HOST} --host=${CLFS_TARGET} \ --prefix=/usr --cache-file=config.cache \ --enable-no-install-program=kill,uptime \ --enable-install-program=hostname Compile the package: make Install the package: make DESTDIR=${CLFS} install Move programs to the locations specified by the FHS: mv -v ${CLFS}/usr/bin/{cat,chgrp,chmod,chown,cp,date} ${CLFS}/bin mv -v ${CLFS}/usr/bin/{dd,df,echo,false,hostname,ln,ls,mkdir} ${CLFS}/bin mv -v ${CLFS}/usr/bin/{mv,pwd,rm,rmdir,stty,true,uname} ${CLFS}/bin mv -v ${CLFS}/usr/bin/chroot ${CLFS}/usr/sbin Other Coreutils programs are used by some of the scripts in the CLFS-Bootscripts package. As /usr may not be available during the early stages of booting, those binaries need to be on the root partition: mv -v ${CLFS}/usr/bin/{[,basename,head,install,nice} ${CLFS}/bin mv -v ${CLFS}/usr/bin/{readlink,sleep,sync,test,touch} ${CLFS}/bin ln -sfv ../../bin/install ${CLFS}/usr/bin Contents of Coreutils Installed programs [, base64, basename, cat, chcon, chgrp, chmod, chown, chroot, cksum, comm, cp, csplit, cut, date, dd, df, dir, dircolors, dirname, du, echo, env, expand, expr, factor, false, fmt, fold, groups, head, hostid, hostname, id, install, join, link, ln, logname, ls, md5sum, mkdir, mkfifo, mknod, mktemp, mv, nice, nl, nohup, od, paste, pathchk, pinky, pr, printenv, printf, ptx, pwd, readlink, rm, rmdir, runcon, seq, sha1sum, sha224sum, sha256sum, sha384sum, sha512sum, shred, shuf, sleep, sort, split, stat, stty, sum, sync, tac, tail, tee, test, timeout, touch, tr, true, truncate, tsort, tty, uname, unexpand, uniq, unlink, users, vdir, wc, who, whoami, and yes Short Descriptions base64 Base64 encode/decode data and print to standard output base64 basename Strips any path and a given suffix from a file name basename cat Concatenates files to standard output cat chcon Changes security context for files and directories chcon chgrp Changes the group ownership of files and directories chgrp chmod Changes the permissions of each file to the given mode; the mode can be either a symbolic representation of the changes to make or an octal number representing the new permissions chmod chown Changes the user and/or group ownership of files and directories chown chroot Runs a command with the specified directory as the / directory chroot cksum Prints the Cyclic Redundancy Check (CRC) checksum and the byte counts of each specified file cksum comm Compares two sorted files, outputting in three columns the lines that are unique and the lines that are common comm cp Copies files cp csplit Splits a given file into several new files, separating them according to given patterns or line numbers and outputting the byte count of each new file csplit cut Prints sections of lines, selecting the parts according to given fields or positions cut date Displays the current time in the given format, or sets the system date date dd Copies a file using the given block size and count, while optionally performing conversions on it dd df Reports the amount of disk space available (and used) on all mounted file systems, or only on the file systems holding the selected files df dir Lists the contents of each given directory (the same as the ls command) dir dircolors Outputs commands to set the LS_COLOR environment variable to change the color scheme used by ls dircolors dirname Strips the non-directory suffix from a file name dirname du Reports the amount of disk space used by the current directory, by each of the given directories (including all subdirectories) or by each of the given files du echo Displays the given strings echo env Runs a command in a modified environment env expand Converts tabs to spaces expand expr Evaluates expressions expr factor Prints the prime factors of all specified integer numbers factor false Does nothing, unsuccessfully;
