Building

Requirements
Build tc-native requires three components to be installed:

APR library

OpenSSL libraries

Java SE Development Kit (JDK)

In debian based Linux those dependencies could be installed by something like:
        apt-get install libapr1.0-dev libssl-dev
      
In rpm based Linux those dependencies could be installed by something like:
        yum install apr-devel openssl-devel
      
UNIX
On all the POSIX systems (Linux, Solaris, HP-UX, AIX etc...) a well-known configure and make is used to build tc-native.
In the jni/native runs:
    ./configure --help
    
to read the description of all the parameters.
    ./configure --with-apr=$HOME/APR \
                --with-java-home=$JAVA_HOME \
                --with-ssl=$HOME/OPENSSL \
                --prefix=$CATALINA_HOME
    
to create the includes and makefiles to be able to build tc-native.
Where:
$HOME/APR is something like /usr/bin/apr-1-config or the path where apr is installed.
$JAVA_HOME is something /home/jfclere/JAVA/jdk1.5.0_09 path to a JDK installation. Any JDK should work but it is advisable to use the same JVM version the JVM you use with Tomcat.
$HOME/OPENSSL is the path where OpenSSL is installed.
$CATALINA_HOME is the path where the produced libraries will be installed. Something like $HOME/apache-tomcat-6.0.16/

The configure is able to guess most of OpenSSL standard installations. So most of the time the following will be enough:
    ./configure --with-apr=/usr/bin/apr-1-config \
                --with-java-home=/home/jfclere/JAVA/jdk1.5.0_09/ \
                --with-ssl=yes \
                --prefix=$CATALINA_HOME
    
To build the libraries and install them:
    make && make install
    
The libraries will be found in $CATALINA_HOME/lib
Windows

Download the windows sources of tc-native and extract them.

Download OpenSSL sources (See Binary Distributions) OpenSSL is a crypto software so check if you are allowed to download it. If not you can still use tc-native without SSL.

Download APR sources for Windows. (See Download) Extract them in jni and rename the apr-1.x.y directory to apr.

Use MS Visual Studio to open the workspace of the APR sources and build the library (libapr).

Use MS Visual Studio to open the workspace of the tc-native sources, adjust the OpenSSL includes and libraries location change the name of the libraries libeay32 and libssleay to libeay32MT and libssleayMT and build the tcn-native library. That should create a tcnative-1.dll.

Install and tests

UNIX

Edit $CATALINA_HOME/bin/setenv.sh (creating the file if necessary) and add the path to the tc-native libraries to LD_LIBRARY_PATH. Something like:
    LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$CATALINA_HOME/lib
    export LD_LIBRARY_PATH
   
Start tomcat and check for the messages like this ones:
    Feb 8, 2008 12:27:41 PM org.apache.catalina.core.AprLifecycleListener init
    INFO: Loaded APR based Apache Tomcat Native library 1.x.y.
    Feb 8, 2008 12:27:41 PM org.apache.catalina.core.AprLifecycleListener init
    INFO: APR capabilities: IPv6 [true], sendfile [true], accept filters [false], random [true].
    Feb 8, 2008 12:27:41 PM org.apache.coyote.http11.Http11AprProtocol init
    INFO: Initializing Coyote HTTP/1.1 on http-8080
   
Refer to the tomcat documentation to configure the connectors (See Tomcat6.0.x and Tomcat5.5.x)

Windows

Edit $CATALINA_BASE\bin\setenv.bat (creating the file if necessary) and add the path to the tc-native libraries, apr and OpenSSL to PATH. For example:

    set PATH=%PATH;C:\cygwin\home\support\tomcat-native-current-win32-src\jni\native\Debug;C:\cygwin\home\support\tomcat-native-current-win32-src\jni\apr\Debug;C:\OpenSSL\lib\VC

Start tomcat and check for the messages like this ones:

    INFO: Loaded APR based Apache Tomcat Native library 1.x.y.
