  General Build Instructions
  ==========================

  To build tomcat-connectors you need to run "configure" and "make":

  ./configure [autoconf arguments] [tomcat-connectors arguments]
  make

  It is possible to set CFLAGS and LDFLAGS to add some platform specifics:

  LDFLAGS=-lc \
  ./configure -with-apxs=/home2/local/apache/bin/apxs

  To find out about all available configure flags use

  ./configure --help


  Build for the Apache HTTP Server
  ================================

  If you want to build mod_jk for the Apache HTTP Server
  you need to locate the apxs tool coming with the Apache
  HTTP server. If apxs is located in /usr/sbin/apxs, run:

  ./configure --with-apxs=/usr/sbin/apxs
  make

  The resulting module file mod_jk.so of mod_jk will be
  located in the directory apache-2.0 (for any version
  of Apache 2.x) respectively apache-1.3 (for Apache 1.3).

  Simply copy the file to your web server modules or libexec
  directory.


  Apache related configure arguments for tomcat-connectors
  --------------------------------------------------------

  --with-apxs[=FILE]

  FILE is the location of the apxs tool. Default is finding apxs in PATH.
  It builds a shared Apache module. It detects automatically the Apache
  version. (2.x and 1.3)

  --with-apache=DIR

  DIR is the path where apache sources are located.
  The apache sources should have been configured before configuring mod_jk.
  DIR is something like: /home/apache/apache_1.3.19
  It builds a static Apache module.

  --enable-EAPI
  This parameter is needed when using Apache 1.3 and mod_ssl, otherwise you
  will get the error message: "this module might crash under EAPI!" when
  loading libjk.so in httpd.

  Static build needs more tests, and we strongly recommend dynamic build
  using DSO/APXS.


  Building for Netscape/iPlanet/SunONE WebServer
  ==============================================

  Building uses the following command sequence:

  ./configure --enable-netscape
  cd netscape
  make -f Makefile.solaris

  This assumes that IPLANET_HOME is defined and points to
  your iPlanet install path (eg: /opt/SUNWwbsvr).

  By default GCC will be used. You can use Sun CC by providing
  CC=cc on the make command line:

  make -f Makefile.solaris CC=cc IPLANET_HOME=/opt/SUNWwbsrv70 EXTRA_CFLAGS=-m64


  Misc Notes
  ==========

  Build for Multiple Web Servers
  ------------------------------

  If you want to build for multiple web servers, you need
  to call "make clean" between the individual builds.

  HP-UX build notes
  -----------------

  If you plan to use GCC on HP-UX to build mod_jk, be sure to
  have -DHPUX11GCC defined (usually by setting CLAGS before configure)

  Reports are that the stripped down cc version that ships with
  HP-UX won't be able to work, you should have the HP add-on ANSI C
  Compiler package.

  A good repository for HP-UX gnu tools is:

  http://gatekeep.cs.utah.edu/

  Solaris build notes
  -------------------

  The build should work with the GNU gcc compiler, on both
  SPARC and x86 architecture systems.

  A good repository for Solaris gnu tools is:

  http://www.sunfreeware.com/

  Be carefull when mixing native compiler and gnu compiler, and
  ensure that apache and mod_jk will be compiled and linked with
  the same tools (i.e. full Solaris or full GNU)


  Building from the subversion tree
  =================================

  This is only necessary if you want to build a not yet
  released versions. When using a subversion tree,
  "buildconf.sh" must be run before configure. This script uses
  the auto tools to provide the following files:

  - libtool files in scripts/build/unix (should copy them?)
  - Makefile.in from Makefile.am
  - aclocal.m4 from different m4 files located on the local machine
  - configure from configure.in and aclocal.m4

  buildconf.sh is known to work with libtool 1.5.2, automake 1.10
  and autoconf 2.59 or newer. The use of more recent versions is
  strongly encouraged, e.g. for reliable detection of the
  features of recent version of operating systems (e.g. AIX 6.1).
  The script is run without arguments:

  ./buildconf.sh

  If you see error messages from automake, don't care about them.
  After running buildconf you can build as usual using configure
  and make.
