@@ -10,55 +10,7 @@ for doing incremental dumps has been significantly changed.
|
||||
This distribution also includes rmt, the remote tape server (which
|
||||
must reside in /etc). The mt program is in the GNU cpio distribution.
|
||||
|
||||
To compile tar (and rmt, if your system has the needed features) on
|
||||
Unix-like systems:
|
||||
|
||||
1. Type `./configure'. This shell script attempts to guess correct
|
||||
values for various system-dependent variables used during compilation,
|
||||
and creates the file `Makefile'. This takes a couple of minutes.
|
||||
|
||||
If you want to compile in a different directory from the one
|
||||
containing the source code, `cd' to that directory and run `configure'
|
||||
with the option `+srcdir=DIR', where DIR is the directory that
|
||||
contains the source code. The object files and executables will be
|
||||
put in the current directory. This option only works with versions of
|
||||
`make' that support the VPATH variable. `configure' ignores any other
|
||||
arguments you give it.
|
||||
|
||||
If your system requires unusual options for compilation or linking
|
||||
that `configure' doesn't know about, you can give `configure' initial
|
||||
values for variables by setting them in the environment; in
|
||||
Bourne-compatible shells, you can do that on the command line like
|
||||
this:
|
||||
$ CC='gcc -traditional' LIBS=-lposix ./configure
|
||||
|
||||
2. If you want to change the directories where the programs will be
|
||||
installed, or the optimization options, edit `Makefile' and change
|
||||
those values. If you have an unusual system that needs special
|
||||
compilation options that `configure' doesn't know about, and you
|
||||
didn't pass them in the environment when running `configure', you
|
||||
should add them to `Makefile' now. Alternately, teach `configure' how
|
||||
to figure out that it is being run on a system where they are needed,
|
||||
and mail the diffs to the address listed at the top of this file so we
|
||||
can include them in the next release.
|
||||
|
||||
3. Type `make'.
|
||||
|
||||
4. If your system needs to link with -lPW to get alloca, but has
|
||||
rename in the C library (so WANT_RENAME is not used), -lPW might give
|
||||
you an incorrect version of rename. On HP-UX this manifests itself as
|
||||
an undefined data symbol called "Error" when linking tar. If this
|
||||
happens, use `ar x' to extract alloca.o from libPW.a and `ar rc' to
|
||||
put it in a library liballoca.a, and put that in LIBS instead of -lPW.
|
||||
This problem does not occur when using gcc, which has alloca built in.
|
||||
|
||||
5. If the programs compile successfully, type `make install' to
|
||||
install them.
|
||||
|
||||
6. After you have installed the programs, you can remove the binaries
|
||||
from the source directory by typing `make clean'. Type `make
|
||||
distclean' if you also want to remove `Makefile', for instance if you
|
||||
are going to recompile tar next on another type of machine.
|
||||
