 $Id: INSTALL,v 1.36 2010/01/18 23:46:09 yaberauneya Exp $

 Requirements
 -------------------

 1. In order to compile ltp you must have make 3.80+ (make 3.81 preferred).
 2. In order to compile and use ltp-scanner (a utility in the pan directory),
    you must have bison/yacc, and flex installed.

 bison can be obtained here:
 - http://ftp.gnu.org/gnu/bison/bison-2.4.1.tar.gz

 Berkeley yacc can be obtained here:
 - ftp://invisible-island.net/byacc/byacc.tar.gz

 flex can be obtained here:
 - http://downloads.sourceforge.net/project/flex/flex/flex-2.5.33/flex-2.5.33.tar.bz2

 make 3.81 can be obtained here:
 - http://ftp.gnu.org/gnu/make/make-3.81.tar.bz2

 If you want to use auto configuration, be sure autoconf-2.61+ & automake-1.10+
 are installed.

 automake-1.10.2's sources can be downloaded from:
 - ftp://ftp.gnu.org/gnu/automake/automake-1.10.2.tar.bz2
 - ftp://ftp.gnu.org/gnu/automake/automake-1.10.2.tar.gz

 autoconf-2.61's sources can be downloaded from:
 - ftp://ftp.gnu.org/gnu/autoconf/autoconf-2.61.tar.bz2
 - ftp://ftp.gnu.org/gnu/autoconf/autoconf-2.61.tar.gz

 autoconf-2.61 also requires m4-1.4.7+ be installed. Its sources can be
 downloaded from:
 - http://ftp.gnu.org/gnu/m4/m4-1.4.7.tar.bz2
 - http://ftp.gnu.org/gnu/m4/m4-1.4.7.tar.gz

 Configuration
 -------------------

 Using autoconf (preferred):
 	$ make autotools # This must be run from "$TOP_SRCDIR"!
 	$ test -d "$TOP_BUILDDIR" || mkdir -p "$TOP_BUILDDIR"
 	$ cd "$TOP_BUILDDIR" && "$TOP_SRCDIR/configure" \
 	  # [configure args go here, e.g. CC=$CC, LDFLAGS=$LDFLAGS, etc]

 Not using autoconf:

 	$ test -d "$TOP_BUILDDIR" || mkdir -p "$TOP_BUILDDIR"
 	$ cp "$TOP_SRCDIR/include/config.h.default" \
 	     "$TOP_BUILDDIR/include/config.h"
 	$ cp "$TOP_SRCDIR/include/mk/config.mk.default" \
 	     "$TOP_BUILDDIR/include/mk/config.mk"
 	$ cp "$TOP_SRCDIR/include/mk/features.mk.default" \
 	     "$TOP_BUILDDIR/include/mk/features.mk"

 	# Fire up your favorite editor and set each value appropriately in
 	# include/mk/config.mk. Uncomment all values commented out, such as
 	# NUMA_LIBS, etc, but only if you're sure that the libraries exist and
 	# can be linked on your system.

 - $TOP_SRCDIR and $TOP_BUILDDIR are the same for in-build-tree scenarios.
 - $TOP_SRCDIR and $TOP_BUILDDIR differ for out-of-build-tree scenarios.

 See the In-build-tree and Out-of-build-tree sections below for more details on
 what to do next...

 Compiling LTP
 -------------------

 "What's in a Path?"
 -------------------

 Before getting started, you should make sure that your build directory and
 source directory are as basic as possible: no commas, colons, semicolons,
 spaces, etc. In fact, this is a relatively good rule of thumb when dealing
 with any [Gnu?] make based opensource project.

 We won't `fix' the `issues' associated with these particular set of build
 errors resulting from non-sane pathnames, because it would introduce unneeded
 complexity into the build system and would require non-trivial effort to fix
 and validate the third-party packages, and thus wouldn't be a sustainable
 model to follow.

 So, we apologize for the inconvenience, but using other characters like
 underscores and dashes should help when disambiguating words between build
 and source pathnames.

 In-build-tree
 -------------------
 In-build-tree support is when you build binaries (applications, binary objects)
 in the same directory where the source files reside.

 	$ make all
 	$ make \
 	  "DESTDIR=$SYSROOT" \
 	  SKIP_IDCHECK=[0|1] \
 	  install

 - Specifying DESTDIR is optional, but required when installing to a non-host
   sysroot, as opposed to the host system's sysroot.
 - Specify SKIP_IDCHECK=1 if and when you don't want to modify /etc/{group,passwd}
   on the target system's sysroot.

 If you get a build error, please report it to ltp@lists.linux.it with
 following information,

  1. The error output before the failure.
  2. If you used configure:
 	i.   include/config.h
 	ii.  include/mk/config.mk
 	iii. config.log

 Out-of-build-tree
 -------------------
 Out-of-build-tree support is when you build binaries (applications, binary
 objects, generated files) outside of the directory where the source files
 reside. This is typically used when cross-compiling for multiple targets.

 NOTE: This is by and large correctly implemented, but there are several corner
 cases, where this isn't implemented properly. Please see TODO for a list of
 items which need fixing in the LTP tree.

 	$ mkdir "$OUT_OF_BUILD_TREE_DIR"
 	$ make \
 	  -C "$OUT_OF_BUILD_TREE_DIR" \
 	  -f "$TOP_SRCDIR/Makefile" \
 	  "top_srcdir=$TOP_SRCDIR" \
 	  "top_builddir=$OUT_OF_BUILD_TREE_DIR"
 	$ make \
 	  -C "$OUT_OF_BUILD_TREE_DIR" \
 	  -f "$TOP_SRCDIR/Makefile" \
 	  "top_srcdir=$TOP_SRCDIR" \
 	  "top_builddir=$OUT_OF_BUILD_TREE_DIR" \
 	  "DESTDIR=$SYSROOT" \
 	  SKIP_IDCHECK=[0|1]
 	  install

 - Specifying DESTDIR is optional, but required when installing to a non-host
   sysroot, as opposed to the host system's sysroot.
 - Specify SKIP_IDCHECK=1 if and when you don't want to modify /etc/{group,passwd}
   on the target system's sysroot.

 Quick Start
 -----------

 1> tar xzf ltp-XXXXXXXX.tar.gz
 2> cd ltp
 3> ./configure
 4> make all
 5> make install
 6> /opt/ltp/runltp

 *NOTE:
 - LTP assumes the existence of the nobody, bin, and daemon users and their
 groups.  If these IDs do not exist, certain tests will fail. The respective
 user and group IDs should be the same, i.e. if `nobody's' user ID is 99, then
 its group ID should also be 99. The names of the groups are irrelevant.
 - The installation directory is /opt/ltp by default. Please see
 "Using autoconf" above and specify the appropriate path via --prefix.
 DESTDIR= is also honored for install and will install into $DESTDIR/$prefix,
 if you want to install into a chroot or a rootfs for instance.

 Detailed Installation
 ---------------------

 Beyond the "Quick Start" instructions, there are only a few other things
 that should be done.  The Linux Test Project build process uses a
 minimalist approach.  There is a lot of room for improvement and
 contributions are welcome.

 1. Log in as root.

 2. Untar the ltp tarball into a spare directory.  There is not a
    standard location for it yet.  We put it in our home directory
    while we're working on it.
    Note that the full path to this location must be accessible for
    unprivileged users, as some tests are run as a different user than root.
    Hence /root is not a good choice on several distributions.

 3. Build and install everything, as described above. Note the minimum software
    requirements above before doing so.

 4. You can run all of the tests sequentially using the example test script
    runalltests.sh.  The script is provided to get you started.
    See ltp-pan(1) for more information on the test driver we have provided.
    It is simple, but it can do a lot of stuff.

    NOTE: The diskio and network tests will NOT be run by the runltp script;
    they are separate from the other tests because of additional required setup
    overhead.

 5. The disk I/O tests can be run by executing the diskio.sh script.  In order
    for these tests to successfully operate a writable high-density 3.5" floppy
    must be in the disk drive and a CD-ROM with more than 100Mb of data must be
    in the CD-ROM drive.  The corresponding tests will fail if either disk is
    missing.

 6. The network tests are executed by running the networktests.sh script. The
    network tests require some configuration for them to work correctly:

      i) First, there MUST be another test machine setup to act as the server
 	to these client side tests.  This machine MUST have the LTP installed
 	in the same exact location, i.e. if the client has /root/ltp, then the
 	server must have /root/ltp.  This is required because certain tests
 	expect to find server files in certain locations.  Make sure to compile
 	the LTP on this server machine also.

     ii) Second, the server must be setup to allow the client to connect using
 	the "r" commands, such as rsh.  This is done by simply creating/editing
 	the ".rhosts" file under /root.  Place the hostname of the client
 	machine in this file to allow root to remotely connect without the use
 	of a password. If server has the PAM system security tool, you need
 	to add the following lines to /etc/securetty:
 		rlogin
 		rsh
 		rexec
 		pts/0
 		pts/1
 		  :
 		pts/9

    iii) Next, certain services must be activated in order for certain tests to
 	execute.  The following services are activated via inetd/xinetd:
 		rlogind
 		ftpd
 		telnetd
 		echo (stream)
 		fingerd
 		rshd
 	 Also, because certain RPC programs are tested, the "portmapper" daemon
 	 MUST be started, as well as NFS server AND lock services.

     iv) Finally, before running the networktests.sh script, two variables must
 	be set within the script file.  The "RHOST" variable should be set to
 	the hostname of the server.  The "PASSWD" variable should be set to
 	root's password on the server machine.  This is necessary for tests
 	such as telnet01 and ftp01.

    You can now successfully execute the networktests.sh script.
    When you would like to run the whole network tests, specify -w option:
 	# ./networktests.sh -w

    When you would like to run the same tests which networktests.sh ran till
    2008, specify no option or -d option:
 	# ./networktests.sh

    You can run the test category which you are interested in, -h option shows
    the list of the test category:
 	# ./netwoktests.sh -h


 Cross compiling
 ---------------

 To cross compile, you must specify the correct variables when running configure.
 e.g. CC, CXX, CXXFLAGS, LDFLAGS, etc...

 After configure has run, it will generate include/mk/config.mk. You can tweak
 settings in there if need be, but you should not specificy settings on the
 command-line when running make.

 uClinux Users
 --------------
 Specify UCLINUX=1 when calling make; -DUCLINUX=1 use is deprecated and highly
 discouraged.

 Variables in Makefile
 ----------------------

 The conventions enforced are standard ones. Here's a quick summary:

 CFLAGS   - used when compiling/linking C code, e.g. -D_GNU_SOURCE (no CPPFLAGS!)

 CXXFLAGS - used when compiling/linking C++ code (no CPPFLAGS!)

 CPPFLAGS - used when preprocessor is run (so C/C++ compiling with $(CPP)
 	   functions, e.g. -I$SYSROOT/usr/include -I$SYSROOT/include -I$SYSROOT

 LDFLAGS  - linker flags, e.g. "-L$SYSROOT/usr/lib" "-L$SYSROOT/lib". DO NOT
 	   PUT LIBRARIES IN THIS LIST (see LDLIBS for that).

 LDLIBS   - libraries listed after objects during link, e.g. -lc, -lpthread,
 	   -lltp.

 See README.mk-devel for a more terse description of what's available.

 Common Issues
 ----------------------

 Issue:    When executing configure it says:

 checking for a BSD-compatible install... /usr/bin/install -c
 checking whether build environment is sane... yes
 checking for gawk... gawk
 checking whether make sets $(MAKE)... yes
 configure: error: cannot run /bin/sh ./config.sub

 Solution: You must upgrade autoconf to 0.10.2+ and m4 to 1.4.7+; config.guess and config.sub aren't necessarily generated with older revisions of the Gnu autotools chain.

 Issue:    When executing make [all] it says:

     " *** No rule to make target `/$*', needed by `pan-all'.  Stop."

 Solution: You must upgrade to make 3.81. Please see the Requirements section above.

 Issue:    When executing make [all] it says something like:

     # ...
     install -m 00644 "/scratch/ltp-dev2/ltp/include/test.h" "/scratch/ltp-install12/include/test.h"
     install -m 00644 "/scratch/ltp-dev2/ltp/include/tlibio.h" "/scratch/ltp-install12/include/tlibio.h"
     install -m 00644 "/scratch/ltp-dev2/ltp/include/usctest.h" "/scratch/ltp-install12/include/usctest.h"
     install -m 00644 "/scratch/ltp-dev2/ltp/include/write_log.h" "/scratch/ltp-install12/include/write_log.h"
     make[1]: Leaving directory `/scratch/ltp-dev2/ltp/include'
     make -C lib -f "/scratch/ltp-dev2/ltp/lib/Makefile" all
     make[1]: Entering directory `/scratch/ltp-dev2/ltp/lib'
     " *** No rule to make target `dataascii.o', needed by `libltp.a'.  Stop." # <-- the error

 Solution: You cannot build LTP with -r / --no-builtin-rules and/or
 	  -R / --no-builtin-variables specified. LTP relies heavily on built-in
 	  implicit rules and variables to function properly.

 Issue:    When executing make (no target, 3.80), it does the following, and doesn't execute all:

     #
     make -C testcases/realtime autotools
     make[1]: Entering directory `/scratch/ltp/testcases/realtime'
     autoheader
     make[1]: Leaving directory `/scratch/ltp/testcases/realtime'

	" *** No rule to make target `/$*', needed by `pan-all'. Stop."

	Solution: You must upgrade to make 3.81. Please see the Requirements section above.

	Issue: When executing make [all] it says something like:

	# ...
	install -m 00644 "/scratch/ltp-dev2/ltp/include/test.h" "/scratch/ltp-install12/include/test.h"
	install -m 00644 "/scratch/ltp-dev2/ltp/include/tlibio.h" "/scratch/ltp-install12/include/tlibio.h"
	install -m 00644 "/scratch/ltp-dev2/ltp/include/usctest.h" "/scratch/ltp-install12/include/usctest.h"
	install -m 00644 "/scratch/ltp-dev2/ltp/include/write_log.h" "/scratch/ltp-install12/include/write_log.h"
	make[1]: Leaving directory `/scratch/ltp-dev2/ltp/include'
	make -C lib -f "/scratch/ltp-dev2/ltp/lib/Makefile" all
	make[1]: Entering directory `/scratch/ltp-dev2/ltp/lib'
	" *** No rule to make target `dataascii.o', needed by `libltp.a'. Stop." # <-- the error

	Solution: You cannot build LTP with -r / --no-builtin-rules and/or
	-R / --no-builtin-variables specified. LTP relies heavily on built-in
	implicit rules and variables to function properly.

	Issue: When executing make (no target, 3.80), it does the following, and doesn't execute all:

	#
	make -C testcases/realtime autotools
	make[1]: Entering directory `/scratch/ltp/testcases/realtime'
	autoheader
	make[1]: Leaving directory `/scratch/ltp/testcases/realtime'
