-GNU `tar' 1.12.lfs.6 is an unofficial port of GNU `tar' 1.12 to Large
-File Summit (LFS) environments like Solaris 2.6 that rely on integer
-system types longer than `long'. Ordinary GNU `tar' 1.12 cannot handle
-files larger than 2 GB when compiled in such environments. This port
-addresses that problem, and fixes some other well-known bugs in GNU tar 1.12.
-Please send bug reports specific to this unofficial version of GNU `tar'
-to <eggert@twinsun.com>.
-
-This is not intended to be a forked release for GNU tar; it's
-just an interim experimental release, mostly intended for
-Large File Summit hosts like Solaris 2.6. The patches of this
-release have all been submitted via the usual channels and
-they should no longer be needed once the next official release
-of GNU tar is out.

Please glance through *all* sections of this
`README' file before starting configuration. Also make sure you read files
`ABOUT-NLS' and `INSTALL' if you are not familiar with them already.

GNU `tar' saves many files together into a single tape or disk
archive, and can restore individual files from the archive. It includes

Besides those configure options documented in files `INSTALL' and
-`ABOUT-NLS', a few extra options may be accepted after `./configure':
-
-* `--with-included-malloc' or `--without-included-malloc' may override
-the automatic choice made by `configure' about using included GNU malloc.
+`ABOUT-NLS', an extra option may be accepted after `./configure':
-* `--with-dmalloc' is a debugging option for looking at memory management
-problems, it prerequires Gray Watson's package, which is available as
-`ftp://ftp.letters.com/src/dmalloc/dmalloc.tar.gz'.
+* `--disable-largefile' omits support for large files, even if the
+operating system supports large files. Typically, large files are
+those larger on 2 GB on a 32-bit host.
The default archive device is now `stdin' on read and `stdout' on write.
The installer can still override this by presetting `DEFAULT_ARCHIVE'
For comprehensive modifications to GNU tar, you might need tools beyond
those used in simple installations. Fully install GNU m4 1.4 first,
-and only then, Autoconf 2.12 with officious patches held in `AC-PATCHES'.
-Install Perl, then Automake 1.1n with officious patches in `AM-PATCHES'.
-You might need Bison 1.25 with officious patches in `BI-PATCHES' (but yacc
-and byacc may be OK for you), and GNU tar itself. All are available on
-GNU archive sites, like in ftp://prep.ai.mit.edu/pub/gnu/, but Automake
-is still ftp://ftp.cygnus.com/pub/tromey/automake-1.1n.tar.gz.

+In an NFS environment, lack of synchronization between machine clocks
+might create difficulties to any tool comparing dates and file time stamps,
like `tar' in incremental dumps. This has been a recurrent problem in
GNU Makefiles for the last few years. We would like a general solution.
* BSD compatibility matters.
Set LIBS to `-lbsd' before configuration (see `INSTALL') if the linker
-complains about undefined `valloc' (AIX) or `bsd_ioctl' (Slackware).
-Also set CPPFLAGS to `-I/usr/include/bsd/sys' before configuration to
-solve dirent problems (NeXT), or to `-I/usr/include/bsd' if <sgtty.h>
-is not found (Slackware).
-
-* `union wait' problems.
-
-Configuration of `union wait' does not always take the best decision.
-If you have this problem, edit file `config.cache' after configuration,
-find the line about `tar_cv_header_union_wait', change `yes' by `no'
-or vice-versa, execute `./config.status', then launch `make'.
-
-* `%lld' unsupported in `printf'.
-
-GNU C has `long long', but the underneath C library might not support
-the `%lld' format. If you have this problem, edit file `config.cache'
-after configuration, find the line about `ac_cv_sizeof_long_long, change
-`8' by `0', execute `./config.status', then launch `make'.
-
-* FreeBSD users -- `configure' fails.
-
-It has been reported that `configure' does not run on FreeBSD 2.1.7,
-because of a buggy `sh'. It works using `bash', however.
-
-* ISC users -- `S_*' symbols undefined.
-
-On ISC 4.1mu, POSIX environment, set CFLAGS to `-posix' and CPPFLAGS to
-`-D_SYSV3' before configuration (see `INSTALL'). This will trigger the
-definition of a few `S_' prefixed symbols from <sys/stat.h>.
+complains about `bsd_ioctl' (Slackware). Also set CPPFLAGS to

-* Ultrix users -- broken `make'.
+* OPENStep 4.2 swap files
-It seems that Ultrix make does not correctly handle shell commands
-having logical connectives in them. Use `s5make' if you have it, try
-`PROG_ENV=SYSTEM_FIVE make' (works on Ultrix 4.4), or install GNU Make.
+Tar cannot read the file /private/vm/swapfile.front (even as root).
+This file is not a real file, but some kind of uncompressed view of
+the real compressed swap file; there is no reason to back it up, so
+the simplest workaround is to avoid tarring this file.
