Building Tomcat from source on MacOS can require some additional work, especially if you want to build all of the optional items such as libtcnative.==

Building Tomcat

...

Building Tomcat itself is fairly straightforward. Simply download the source distribution of Tomcat and follow the indtructions instructions in the BUILDING.txt file bundled with the distribution.

1. Xcode command-line tools, available from Apple's developer tools download site. Make sure you get the proper version for your XCode version (if you have XCode already installed) and your OS version (10.x)
2. Wiki Markup

Download and unpack the libtcnative sources:

...

Next, copy the APR libraries:

No Format
$ cp -a$aR $APR_HOME/libexec/lib/* apache-tomcat-x.y.z-src/output/build/bin/

Finally, if you are using a custom OpenSSL build, copy those libraries as well:

No Format
$ cp -a$aR $OPENSSL_HOME/lib/* apache-tomcat-x.y.z-src/output/build/bin/

Running Tomcat with libtcnative

Tomcat (really Java) needs to know where to find these native libraries. We do that by setting the java.library.path environment variable for the JVM during startup. The easiest way to do this is by setting CATALINA_OPTS on startup. This can be done by adding this line to bin/setenv.sh:

export CATALINA_OPTS="-Djava.library.path=$CATALINA_HOME/bin"

Then you can startup Tomcat as usual, either:

$ bin/startup.sh

or

$ bin/catalina.sh start
