Apache UIMA C++ (Unstructured Information Management Architecture) v3.0.0
-------------------------------------------------------------------------
Getting Started
----------------
Apache UIMA C++ can be used as a standalone framework, but it is primarily intended to be integrated with the Apache UIMA Java framework. Interoperability is enhanced if the uimacpp SDK package is installed directly under the top level directory of the Apache UIMA Java framework.
For information about the Apache UIMA C++ package go to index.html in the uimacpp/docs directory. For more information about Apache UIMA, go to http://uima.apache.org, or to the documentation in the Apache UIMA Java package.
Supported Platforms
--------------------
The Apache UIMA C++ SDK has been built and tested in 64-bit mode
on Linux systems with gcc version 4.8.5. MacOS and Windows versions are delayed
pending user requests.
UIMACPP has dependencies on APR, ICU, Xerces-C and optionally ActiveMQ-cpp
libraries. ActiveMQ-cpp has a dependency on APR-UTIL.
This UIMA C++ SDK has been built with the following versions of these dependencies:
- APR 1.6.5
- ICU 50.2
- XERCES 3.1.4
- ACTIVEMQ CPP 3.9.3
- APR-UTIL 1.6.1
Environment Variables
----------------------
The following environmental variables are needed for UIMA C++ to function properly.
* UIMACPP_HOME should point to the uimacpp directory of your unpacked Apache UIMA C++
distribution. UIMACPP_HOME is used when compiling & linking UIMA C++ components.
* Append $UIMACPP_HOME/bin to your PATH to pick up the runAECpp test driver and
deployCppService utility.
* Append $UIMACPP_HOME/lib to your LD_LIBRARY_PATH (Linux) or DYLD_LIBRARY_PATH (MacOSX)
so that the necessary shared libraries can be found.
Also note that UIMA C++ annotators are built as shared libraries, so they must be in a directory in the LD_LIBRARY_PATH, DYLD_LIBRARY_PATH or PATH (as appropriate to your platform) as well. An example of this is given in the next section.
For better runtime integration between Java and C++, the Apache UIMA Java SDK command line utilities and Eclipse run configurations automatically add $UIMA_HOME/uimacpp/lib to LD_LIBRARY_PATH and DYLD_LIBRARY_PATH, and add $UIMA_HOME/uimacpp/bin to PATH.
Verifying Your Installation
----------------------------
The procedure here is to first test that Apache UIMA C++ is installed and operating correctly. Then if desired, check if the code is interoperating properly with Apache UIMA Java.
Set up the environment as described above. Go to $UIMACPP_HOME/examples/src to build the sample code and add the src directory to the appropriate path as follows.
On Linux: (Please see below Notes on lib/base.mak)
* make -f DaveDetector.mak
* LD_LIBRARY_PATH=$LD_LIBRARY_PATH:`pwd`
On Windows:
From a MSVC Command Prompt:
* devenv DaveDetector.vcproj /build release
* PATH=%PATH%;%CD%
To test the sample code in the C++ environment, change back to the $UIMACPP_HOME/examples directory and run:
* runAECpp descriptors/DaveDetector.xml data
The console should show that a Dave was found in some of the files in the data directory.
To test interoperability with Java using the JNI, enable UIMA-AS by setting UIMA_HOME and
adding $UIMA_HOME/bin to PATH. Then use the runAE.sh utility (use runAE on Windows) to run
DaveDetector from the $UIMACPP_HOME/examples:
* runAE.sh descriptors/DaveDetector.xml data
To test interoperability with UIMA-AS, continuing with above configuration
* Start and ActiveMQ broker using the startBroker.sh command
* Build and deploy the uimacpp MeetingAnnotator component
* cd $UIMACPP_HOME/examples/tutorial/src and run "make -f MeetingAnnotator.mak"
* add this directory to C++ library path: "LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$PWD"
* deploy the service:
deployCppService $UIMACPP_HOME/examples/tutorial/descriptors/MeetingAnnotatorCPP.xml MeetingAnnotator
* deploy MeetingDetectorTAE service that uses this meeting annotator service:
UIMA_DATAPATH=$UIMA_HOME/examples/descriptors deployAsyncService.sh \
$UIMACPP_HOME/examples/tutorial/descriptors/Deploy_MeetingDetectorTAE_RemoteMeeting.xml
* Send work to the two services:
runRemoteAsyncAE.sh tcp://localhost:61616 MeetingDetectorTaeQueue \
-c $UIMA_HOME/examples/descriptors/collection_reader/FileSystemCollectionReader.xml
For more information about the C++ sample code see $UIMACPP_HOME/examples/readme.html.

Notes on lib/base.mak
---------------------
The annotator and application Make files include lib/base.mak.
On Mac OS X, may be necessary to modify the line in base.mak
INCLUDES=-I$(UIMACPP_HOME)/include -I$(UIMACPP_HOME)/include/apr-1
to correctly specify path to the APR include directory.
