The minimal version of cmake is 3.5. +Ensure that you have proper version of cmake installed. + +JVPP depends on VPP packages (Debian or Centos): +* vpp +* vpp-plugins +* vpp-dev (vpp-devel on Centos) + +Vpp and vpp-plugins packages contain API source file, which are used to generate Java API bindings. Vpp dev package +contains header files needed for build. + +Obtaining the source +-------------------- + +You can get JVPP source code from gerrit.fd.io using git: +git clone https://gerrit.fd.io/r/jvpp + +or from github: +https://github.com/FDio/jvpp.git + + +Install dependencies (Optional, one time only) +------------------ + +You can install all dependencies using provided install-dep target: + +.. code-block:: console + + make install-dep + +Cleanup (Optional) +------------------ + +Whenever you need to clean the setup you can use "clean.sh" script in the root folder. This cleans the build and clears +the cache. This is usefull mostly when you change something in JVPP to ensure everything is rebuild from scratch. + +Configuring using cmake +----------------------- + +Configuration using cmake is very easy, the whole process is automated. All you need to do is issue following command +from JVPP's root directory: + +.. code-block:: console + + cmake . + +This will configure all variables and setup the build. + +Building the source +------------------- + +To build the source use make command: + +.. code-block:: console + + make + +You can also install the library using (you need to use sudo or have root privileges to install libraries): + +.. code-block:: console + + sudo make install + +Building the packages +--------------------- + +During the setup using cmake the operating system is automatically recognised and everything is set up so you can build +packages for your current operating system. Only Debian based (tested on Ubuntu) and Centos (tested on Centos 7) +are supported for now. + +To build the package you need to call: + +.. code-block:: console + + make package + +You can find the packages in build-root/packages folder. + +Getting JVPP jar +================ + +VPP provides java bindings which can be downloaded at: + +* https://nexus.fd.io/content/repositories/fd.io.release/io/fd/vpp/jvpp-core/19.01/jvpp-core-19.01.jar + +Getting JVPP via maven +------------------------------------ + +**1.

+This package contains basic examples for jvpp. To run the examples:
+
+- Make sure VPP is running
+- From VPP's build-root/ folder execute:
+  - release version: sudo java -cp build-vpp-native/vpp/vpp-api/java/jvpp-registry-18.01.jar:build-vpp-native/vpp/vpp-api/java/jvpp-core-18.01.jar io.fd.vpp.jvpp.core.examples.[test name]

+
+Available examples:
+CallbackApiExample - Similar to ControlPingTest, invokes more complex calls (e.g. interface dump) using low level JVpp APIs
+CallbackJVppFacadeNotificationExample - Example of interface notifications using Callback based JVpp facade
+CallbackJVppFacadeExample - Execution of more complex calls using Callback based JVpp facade
+CallbackNotificationApiExample -  Example of interface notifications using low level JVpp APIs
+CreateSubInterfaceExample - Example of sub-interface creation
+FutureApiNotificationExample - Example of interface notifications using Future based JVpp facade
+FutureApiExample - Execution of more complex calls using Future based JVpp facade
+L2AclExample - Example of L2 ACL creation
+LispAdjacencyExample - Example of lisp adjacency creation and read (custom vpe.api type support showcase)
+
+CallbackApiReadPerfTest, FutureApiReadPerfTest, CallbackApiWritePerfTest - test provide two ways to count invocations:
+1) maximum number of invocations and received replyies within 1 sec
+sudo java -cp build-vpp-native/vpp/vpp-api/java/jvpp-registry-18.01.jar:build-vpp-native/vpp/vpp-api/java/jvpp-core-18.01.jar io.fd.vpp.jvpp.core.examples.[test name]
+2) measure time in ns from first request to receiving last reply over set amount of requests

+This package contains basic tests for jvpp. To run the tests:
+
+- Make sure VPP is running
+- From VPP's build-root/ folder execute:
+  - release version: sudo java -cp build-vpp-native/vpp/vpp-api/java/jvpp-registry-17.10.jar:build-vpp-native/vpp/vpp-api/java/jvpp-core-17.10.jar io.fd.vpp.jvpp.core.test.[test name]
+  - debug version: sudo java -cp build-vpp_debug-native/vpp/vpp-api/java/jvpp-registry-17.10.jar:build-vpp_debug-native/vpp/vpp-api/java/jvpp-core-17.10.jar io.fd.vpp.jvpp.core.test.[test name]
+
+Available tests:
+CallbackApiTest - Similar to ControlPingTest, invokes more complex calls (e.g. interface dump) using low level JVpp APIs
+CallbackJVppFacadeNotificationTest - Tests interface notifications using Callback based JVpp facade
+CallbackJVppFacadeTest - Execution of more complex calls using Callback based JVpp facade
+CallbackNotificationApiTest - Tests interface notifications using low level JVpp APIs
+ControlPingTest - Simple test executing a single control ping using low level JVpp APIs
+CreateSubInterfaceTest - Tests sub-interface creation
+FutureApiNotificationTest - Tests interface notifications using Future based JVpp facade
+FutureApiTest - Execution of more complex calls using Future based JVpp facade
+L2AclTest - Tests L2 ACL creation
+LispAdjacencyTest - Tests lisp adjacency creation and read (custom vpe.api type support showcase)
