  Building and Installing TAO

   The following table summarizes platforms on which TAO runs:

   Fully  supported, i.e., continually tested and used daily Solaris 2.5,
   2.6,   and  7,  Windows  NT/2000  (MSVC  5.0  and  6.0),  Linux/Intel,
   Linux/Alpha,  VxWorks, LynxOS, Digital UNIX 4.0 and 5.0, IRIX 6.x, and
   QNX Neutrino 2.0
   Nearly fully supported, i.e., periodically tested Windows 9x/ME, HP/UX
   10.x and 11.x, AIX 4.x
   Partially  supported, i.e., infrequently tested FreeBSD, NetBSD, SunOS
   4.x, Chorus
   Planned  support,  i.e.,  pending  pSoS, MVS, Windows CE, Tandem, SCO,
   UnixWare

   Any UNIX/POSIX/Win32 variation is a potential target platform for ACE.
   If  you  have [1]porting questions or have a problem compiling the ACE
   wrappers  on  the  platforms  shown  above please send email to either
   [2]ACE  Newsgroup or the [3]ACE mailing list and we'll try to help you
   fix  the  problems.  You  can  also submit bug reports and enhancement
   requests in our [4]bug tracking system.

   TAO  can  be obtained [5]electronically via the WWW and ftp. [6]ACE is
   bundled  with  the  TAO  release.  You'll  always need the most recent
   version of ACE because TAO tracks changes to ACE very closely.
     _________________________________________________________________

  On UNIX platforms

    1. Set  ACE_ROOT  environment  variable  as  outlined  in  the [7]ACE
       installation notes.
    2. Build and install ACE under $ACE_ROOT.
          + Change directory to $ACE_ROOT/ace and execute [8]make.
          + Also build GPERF under $ACE_ROOT/apps/gperf
    3. Set TAO_ROOT environment variable to $ACE_ROOT/TAO.
    4. Build and install the TAO release under $TAO_ROOT.
       The  easiest  and  recommended  way  to  compile  the complete TAO
       distribution  by  simply simply executing [9]make in the $TAO_ROOT
       directory.
       A  smaller  subset,  that  may  be  of  interest to test basic TAO
       functionality,      is:      $TAO_ROOT/tao,     $TAO_ROOT/TAO_IDL,
       $TAO_ROOT/tests/Param_Test.  Then  you can execute the run_test.pl
       script    in    $TAO_ROOT/tests/Param_Test   and/or   follow   the
       instructions contained in the README file in the same directory.
       If  you  wish  to  compile  the  services  distributed  with  TAO,
       including the Naming_Service you must include $TAO_ROOT/orbsvcs to
       the list above.
    5. To  test  that  the  TAO  release  is  properly configured, follow
       instructions    on    executing   the   various   examples   under
       $TAO_ROOT/tests.

    A Note On Make

   Since  TAO  is built atop ACE, TAO re-uses ACE's Makefile structure as
   well.  Thus,  just  like  ACE requires GNU Make, so too does TAO. More
   exactly,  versions  of  make which are known to not work include those
   from Solaris 4.x and 5.x, HP-UX, the latest BSD, etc.

   GNU Make can be obtained from various places in source form.
     _________________________________________________________________

  For Cross-Compiled Targets, such as VxWorks and LynxOS

   If  you are building TAO for a VxWorks target, please see the detailed
   instructions   for   building   and   installing   ACE   and   TAO  in
   [10]$ACE_ROOT/ACE-INSTALL.html.

   Cross-compiling  TAO  is  not  much  different  than  building  it for
   self-host. The one major difference is that TAO's IDL compiler must be
   built and run on the host; it's not necessary to run it on the target.
   There  are  several  ways  to  do this, below we document the two most
   common approaches:

    Modifying the default location for the IDL compiler

   By   default  TAO  assumes  that  the  IDL  compiler  is  located  in:
   $TAO_ROOT/TAO_IDL/tao_idl  and  that  the  GPERF  tool  is  located in
   $ACE_ROOT/bin/gperf,  this  is  fine  for  hosted  builds, but not for
   cross-compilation.   Unfortunately   there  is  no  good  default  for
   cross-compilation  builds  because  different sites choose a different
   location for their tools.

   You  can  override  the  default  values  by  adding two lines in your
   platform_macros.GNU file, as follows:
$ echo 'TAO_IDL := /your/path/tao_idl' \
     >> platform_macros.GNU
$ echo 'TAO_IDLFLAGS := -g /your/path/gperf' \

   You could even use:
$ echo 'TAO_IDL := tao_idl' \
     >> platform_macros.GNU
$ echo 'TAO_IDLFLAGS := -g gperf' \

   if the tools are in your path.

   Obviously  you  must  first  build  the  tools  for the host platform,
   typically you would do this as follows:
# (1) Create a clone directory for the host:

$ cd ACE_wrappers
$ mkdir -p build/HOST
$ ./bin/create_ace_build build/HOST

# (2) Configure the host build:

$ echo '#include "ace/config-HOST.h"' > build/HOST/ace/config.h
$ echo 'include $(ACE_ROOT)/include/makeinclude/platform_HOST.GNU' \
     > build/HOST/include/makeinclude/platform_macros.GNU

# Often host builds are static:
$ echo 'static_libs_only=1' \
     >> build/HOST/include/makeinclude/platform_macros.GNU

# (3) Build the host tools

$ cd build/HOST
$ export ACE_ROOT=$PWD
$ make -C ace
$ make -C apps/gperf
$ make -C TAO/TAO_IDL

   Then  configuring  the  location  of the tools for the target could be
   done as shown here:
# (4) Create a clone directory for the target:

$ cd ACE_wrappers
$ mkdir -p build/TARGET
$ ./bin/create_ace_build build/TARGET

# (5) Configure the target build:

$ echo '#include "ace/config-TARGET.h"' > build/HOST/ace/config.h
$ echo 'include $(ACE_ROOT)/include/makeinclude/platform_TARGET.GNU' \
     > build/TARGET/include/makeinclude/platform_macros.GNU

# (6) Configure the TARGET build to use the HOST IDL compiler and
#     gperf tools, as described above.

    Alternative configuration, using links

   Some  developers  prefer to set up the host tools using symbolic links
   (Unix)  or  copy  of  tao_idl (NT). By way of example, here is how you
   could  setup  a  croos-compilation  environment  for Unix, the host is
   SunOS5/g++,  the  target  is  VxWorks.  It  assumes  that  the ACE+TAO
   distribution  has  been unpacked, with TAO below ACE_wrappers. It uses
   the  ACE_wrappers/bin/create_ace_build script to create a shadow build
   tree:
    1. cd ACE_wrappers
    2. bin/create_ace_build SunOS5_g++
    3. bin/create_ace_build vxworks
    4. cd build/vxworks/TAO
    5. /bin/rm -r TAO_IDL
    6. ln -s ../../SunOS5_g++/TAO/TAO_IDL

   To build on the host:
    1. cd build/SunOS5_g++
    2. export ACE_ROOT=`pwd`; export
       LD_LIBRARY_PATH=`pwd`/ace:$LD_LIBRARY_PATH
    3. (cd ace; make && cd ../tests; make && cd ../TAO; make) > make.log
    4. cd ../vxworks
    5. export ACE_ROOT=`pwd`
    6. (cd ace; make && cd ../tests; make && cd ../TAO; make) > make.log

   For  NT  hosts,  please see the detailed instructions for building and
   installing  ACE  and  TAO in [11]../ACE-INSTALL.html, and [12]Building
   ACE on Tornado/NT hosts for VxWorks targets

   Please  note that dynamic loading of libraries is not supported by TAO
   for    any   cross-compiled   target.   Therefore,   dynamic   service
   configuration of the TAO ORB is not supported.

   If using perfect hashing, TAO_IDL needs gperf to be built on the host.
   That's  the  default  on  many  platforms.  First,  build gperf in the
   ACE_wrappers/apps/gperf/src/ directory. Then, add a symlink or copy to
   the bin/ directory for the target.

    Which one is right for me?

   Using  links  to cross-compile TAO may appear simpler at first glance.
   However,  storing  the  location  in  the  platform_macros.GNU is more
   amenable  for sites where many developers share the same configuration
   files,  or  where  ACE+TAO  are  compiled once and used by a medium or
   large size group.
     _________________________________________________________________

  On Windows NT and Windows 2000

   TAO_IDL  does  not contain its own preprocessor, so it needs to use an
   external  preprocessor.  Depending on which compiler was used to build
   TAO_IDL,  the  default  preprocessor  will  change.  For  example,  if
   compiled  with  MSVC,  TAO_IDL will look for CL.EXE in the path. There
   are  cases  where this will not work, such as in cross-compiling or if
   the  preprocessor  is  not  in the path. These situations require that
   environment  variables are set on the machine to override the built-in
   settings.  More  information  about these environment variables can be
   found in the [13]TAO_IDL documentation.

   It  is  also advisable to set either the ACE_ROOT environment variable
   as  outlined  in  the  [14]ACE  installation  notes  or  the  TAO_ROOT
   environment variable. This is only required if you are planning to use
   the  <orb.idl>  standard include in your IDL code. Notice that some of
   the  TAO  services  use this feature, so you are better off definining
   the environment variable in all cases.
   Remember to [15]set up ACE before building TAO.

    Visual C++ 5.0/6.0

   It  works  best  if  TAO  is  placed in ACE_wrappers so TAO ends up in
   ACE_wrappers\TAO  because  the Visual C++ 5/6 Project files are set up
   to  work  in  this  configuration.  If you move it, then make sure you
   change  the project files to look for the include and library files in
   the correct place.
    1. Make sure ACE is built (For Visual C++ 5.0/6.0, use ace.dsw).
    2. First  make  sure  ACE_wrappers\bin  is  listed  in the Executable
       Directories  in Tools|Options. This is needed if using the TAO_IDL
       compiler under MSVC. If you intend to also use the release version
       of   the  libraries,  also  add  ACE_wrappers\bin\Release  to  the
       directories.  Note:  The order that these are listed is important.
       If  your  main  development  is with the debug versions, make sure
       \bin is before \bin\Release, otherwise put the \bin\Release first.
       Because  the  output  names  for the release and debug versions of
       TAO_IDL  are the same, extra care must be taken when both versions
       are generated simulataneously.
    3. Load the workspace tao\TAO.dsw and build the TAO library.
    4. To     build     the    Cubit    test,    load    the    workspace
       performance-tests\Cubit\TAO\IDL_Cubit\IDL_Cubit.dsw and build both
       client and server.

    TAOACE.dsw and other collection dsw files

   TAOACE.dsw  is  a Visual C++ 5.0/6.0 workspace that loads the projects
   ACE,  TAO,  TAO_IDL (the compiler), gperf, the orb services libraries,
   and  the standalone executables (such as Naming Service, etc.). It can
   be used to build all the files needed to build/run TAO applications.

    Borland C++ Builder

   To  build  TAO using C++Builder please follow the [16]ACE installation
   notes, with the difference being that you should run:

     make -f Makefile.bor

   from the ACE_ROOT\TAO directory instead of ACE_ROOT\ace.

   For more detailed information on building and using TAO with Borland's
   C++  Builder  environment,  please see the [17]online help provided by
   [18]Christopher Kohlhoff.

    Upgrading From Older Releases

   When  a  newer  version of ACE/TAO is installed, rebuild all should be
   used to make sure everything is built correctly.

    Changing Include Paths

   If  you prefer #include <corba.h> over #include <tao/corba.h> then you
   will  need to change your Project Settings to also contain the TAO/tao
   directory. You'll find this in the C/C++ settings under Input.

    Creating Static Libraries (*.lib)

   TAO,  orbsvcs,  TAO_IDL,  and  the  Simple Test all have extra project
   files  for  static  library builds. TAOACE_static.dsw contains some of
   these  projects,  and  is set up much like [19]TAOACE.dsw, except that
   there  are  not  as many static projects as their are dynamic projects
   and their isn't the same dependencies set up.

   To  use  the static libraries in a project, make sure to the following
   settings are used in the Project Settings.
     * C/C++  |  General: Add the Preprocessor Definitions ACE_HAS_DLL=0,
       ACE_OS_HAS_DLL=0  and  whatever  other libraries that are included
       (such as TAO_HAS_DLL=0)
     * Link: Link with the static libs, such as TAOs.lib or TAOsd.lib

  How to add IDL files into your Visual C++ projects

   Point of contact: [20]Nanbor Wang.

   Each  IDL  file generates .h, .i and .cpp files. Here is an example of
   adding an IDL file named foobar.idl into a VC project.
    1. Create/open  the workspace. In addition to creating server project
       and  client  project,  create  a  separate  "Utility Project" call
       foobar_idl  for  compiling  the  shared IDL file. Add the IDL file
       <foobar.idl>  to  foobar_idl  project  and other non-IDL generated
       files into both client and server projects.
    2. Added foobarC.h, foobarC.i, foobarC.cpp, foobarS.h, foobarS.i, and
       foobarS.cpp   into   server   project  and  foobarC.h,  foobarC.i,
       foobarC.cpp into client projects.
    3. Now  open  the  project  setting  window of foobar_idl (Project ->
       Setting...  or  just  press  Alt-F7.)  Select  the IDL file in the
       projects.  Choose to set the setting for "All Configuration." Make
       sure  the  "Always  use custom build step" is checked and "Exclude
       from build" is unchecked.
    4. Click  on  the  "Custom  Build"  tab.  Add this entry as the build
       command for IDL files:
tao_idl $(InputPath) -o $(InputDir) -I $(InputDir)
       Notice that your absolute path to TAO_IDL may vary.
    5. Now add the following entries as "Output file(s)."
      $(InputDir)\$(InputName)S.h
      $(InputDir)\$(InputName)C.h
      $(InputDir)\$(InputName)C.i
      $(InputDir)\$(InputName)C.cpp
      $(InputDir)\$(InputName)S.i
      $(InputDir)\$(InputName)S.cpp
      $(InputDir)\$(InputName)S_T.h
      $(InputDir)\$(InputName)S_T.i
      $(InputDir)\$(InputName)S_T.cpp

       Add only one entry in each line.
    6. You might also want to add the TAO_IDL compiler in as a dependency
       here  if  you  update  TAO  often.  That  way,  if the compiler is
       changed,  the  IDL  files are recompiled automatically in the next
       build.
    7. We are all set. Click OK.
    8. Add   foobarC.cpp  and  foobarS.cpp  to  the  server  project  and
       foobarC.cpp into the client project.
    9. Make  both  client  and  server  projects  dependent  projects  of
       foobar_idl  project  to make sure the IDL file get compiled before
       client and server projects.

   Notice  that  these  procedures only setup the IDL compiler to perform
   correctly.

   P.S.  If  anyone  knows how to set a default setting in VC so we don't
   need to perform these procedures every time a new project gets set up,
   please let us know. Thanks.
     _________________________________________________________________

  Perl Scripts

   Several of TAO's tests and examples contain perl scripts that automate
   the  execution  of these tests. The scripts are found as "run_test.pl"
   in the directory of the test.

   The  versions  of  perl  that  we  use are 5.005_02 on NT and 5.003 on
   Solaris.  The  scripts  may  work  on earlier versions of perl, but we
   cannot say for sure that they do.
     _________________________________________________________________

  Native Exceptions

   TAO  will  use native exceptions if TAO_HAS_EXCEPTIONS is defined when
   it  is  compiled.  This  can  be accomplished in two ways: by defining
   ACE_HAS_EXCEPTIONS  in  the  config.h  or config-*.h files (such as on
   Windows) or by using make exceptions=1 when you compile TAO.

   Take  note  though,  that  this  only  enables support in ACE/TAO, the
   correct  compiler  flags  must also be given to the compiler to enable
   them.
     _________________________________________________________________

  minimumTAO

   By  default,  all components in TAO will be compiled. If you only want
   support  for [21]minimumTAO, define TAO_HAS_MINIMUM_CORBA. This can be
   accomplished  in  two  ways:  by defining TAO_HAS_MINIMUM_CORBA in the
   config.h  or orbconf.h files or by using make minimum_corba=1 when you
   compile TAO.
   WARNING:  Make  sure that if you build liborbsvcs with minimum_corba=1
   you also build libTAO with minimum_corba=1!
     _________________________________________________________________

  Connection Caching feature

   By  default,  TAO  includes the connection caching and purging feature
   which  reuses  "old"  connections  by  purging  them  according to the
   caching  strategy  opted  for  (Least  Recently Used, Least Frequently
   Used,  First  In  First  Out).  This way socket descriptors are reused
   thereby increasing scalability.

   This   feature  can  be  controlled  by  defining  or  commenting  out
   TAO_USES_ROBUST_CONNECTION_MGMT in $TAO_ROOT/tao/orbconf.h.

   But  the  code  related to this feature consists of classes with large
   template  lists  and  can  cause  problems with linkers and assemblers
   which cant grok long names.

   Tips:

   Check on SunOS5.6 (and above) whether the assembler used is of the Sun
   Workshop  5  version  else  you  could  get  linker errors due to huge
   symbols.

   If  using egcs2.95 as the compiler the -fsquangle option could be used
   which shortens the symbol names. Thanks to [22]Skye Sweeney for trying
   it  out  and  [23]Ossama  Othman for discovering the option with egcs.
   Note:  Both  the  ACE library and TAO library need to built using this
   option.
