1. General
----------------

UIMACPP enables analytics written in C++, Python, Perl and Tcl to be
easily integrated into the UIMA Java framework.

The Apache UIMA C++ SDK contains UIMACPP as well as all prerequisite 
components. The SDK is intended to enable user's annotator code 
be packaged for integration into a UIMA pipeline and to make it
easier to redistribute UIMACPP-based applications.  This also allows 
different UIMACPP annotators, each using different versions of UIMACPP, 
to be integrated into a common UIMA pipeline on the same machine. For this 
reason the SDK contains UIMACPP as well as all prerequisite components.  

To build the SDK, it is recommended that the prerequisites be built from source.
The SDK build process must be configured with the location of the install directory for each
of the dependencies. It locates the headers and libraries of the dependencies relative
to the specified location. 

Alternatively, on Linux, UIMACPP can be built and installed on a machine along
with all its prerequisites in the standard system directories. In this case the 
prerequisites can be installed from binary distributions.

UIMACPP runtime prerequisites are: 

Tool        Recommended Version
-------------------------------
APR           >= 1.6.5
ICU           == 50.2
Xerces-C      >= 3.1.4
JDK           for building the JNI interface
ActiveMQ CPP  >= 3.9.3  (optional) to build the UIMA-AS service wrapper
APR-util      >= 1.6.1  (optional) an ActiveMQ prerequisite


On Linux the following GNU build tools are required:

Tool        Recommended Version
-------------------------------
autoconf    >= 2.69
automake    >= 1.13
libtool     >= 2.4

On Windows, UIMACPP is built with Microsoft Visual Studio. The UIMA C++ MSVC projects 
are Microsoft Visual Studio 8 (2005) projects.  

The SDK build process also builds the documentation and requires doxygen for building 
the documentation.

The Apache UIMA C++ SDK has been built and tested in 64-bit mode on Linux systems with gcc version 4.8.5;
Mac OSX 64-bit and Windows versions are currently delayed.

For up-to-date build instructions. please see these pages on the Apache UIMA site: 
https://uima.apache.org/dev-quick.html
https://uima.apache.org/doc-uimacpp-build.html

-------------------------
2. Building on Unix/Linux
-------------------------

To build an SDK it is recommended that all prerequisite components, APR, ICU, Xerces-C,
ActiveMQ-cpp and APR-util be built from source and installed by running "make
install". They need not be installed in system directories.

Prerequisite installs from compatible binary distributions can be used to build
the UIMACPP components.  At runtime, only one version of ICU can be loaded. Some
binary distributions of Xerces-C are built with ICU and have been reported to have 
problems. In this case, rebuild Xerces-C from source and specify --without-icu argument
to the configure script. 

There is also a dependency on JNI headers from a Java JDK.


Optional pre-build step
-----------------------
If changes are made to configure.ac or Makefile.am, then configure
needs to be re-generated using:

 ./autogen.sh

autogen.sh requires GNU tools at or above the following versions:
automake v1.9.6, autoconf v2.59 and libtool v1.5.24.

Build Steps
-----------

1 Configure and build
  To build the UIMACPP libraries using prerequisites installed in the
  system directories, Simply run:
    ./configure --with-jdk=location_of_jni.h [other options]
    make

  The ./configure script will generate Makefiles customized to your
  system, including detecting available prerequisites that have been
  installed in standard locations.

  By default the install step will put UIMACPP components in
  /usr/local/uimacpp. To build an SDK, install them elsewhere by adding 
  the following option to configure:
  --prefix=install_target_loc e.g. --prefix=~/uimacpp-2.4.0/install

  On Linux jni.h is usually in the JDK's "include" directory. On MacOSX
  jni.h is in the JDK's "Headers" dirctory. In some cases jni.h will
  #include files in other directories. For example, if jni.h includes
  jni_md.h located in a subdirectory named linux, use
  --with-jdk="loc_of_jdk/include -Iloc_of_jdk/include/linux"

  If the prerequisites are not installed in the system directories as well as   
  for a full SDK build, additional parameters must be provided to the
  configure script:
  For a full SDK build, all of the following are needed:
      --with-apr=loc_of_apr_install --with-icu=loc_of_icu_install \
      --with-xerces=loc_of_xerces_install --with-activemq=loc_of_amq_install \
      --with-apr-util=loc_of_apr-util_install

  For a build of UIMACPP without UIMA-AS support, specify the option
    --without-activemq and leave out --with-activemq and --with-apr-util.

  For more help on how to customize the build configuration, run:
    ./configure --help

2 Run the test suite
    make check

3 Install and Build the SDK tree
    make install 
    make sdk TARGETDIR=loc_of_sdk_tree [clean]

  The SDK tree will be created in loc_of_sdk_tree/uimacpp. Package by:
    cd loc_of_sdk_tree
    tar czf uimacpp-2.X.Y-bin.tgz uimacpp

4 Optionally, generate source tar ball
    make dist

For additional information on building on Mac OSX, please see Section 4.


----------------------
3. Building on Windows
----------------------

To build an SDK all prerequisite components, APR, ICU, Xerces-C,
ActiveMQ-cpp, APR-util and APR-iconv must first be built, and a
JDK installed. The location of the dependencies must be set in
environment variables APR_HOME, ICU_HOME, XERCES_HOME, ACTIVEMQ_HOME
and JAVA_HOME.

For details on building the dependencies, please see section 5.2 of 
this document.

In order to be able to build annotators, the SDK must be built as
described below in step 4, since the annotator projects use the 
environment variable UIMACPP_HOME to locate the UIMA libraries
and dependencies.

If using MSVC Express Edition, first run these prebuild steps. 
  - cd uimacpp-2.X.Y\src
  - run vcexpress uimacpp.sln and do any conversions as prompted.
  - replace devenv command with vcexpress in the winmake and test/fvt.sh scripts and in all build instructions. 
  - continue with the instructions below.

If using a newer version of MSVC, the uimacpp.sln in uimacpp-2.X.Y\src 
must be converted. 

The following commands assume you are running from a Microsoft Visual
Studio 2005 Command Prompt.

1 Build the UIMA C++ framework in both release and debug:
  cd \uimacpp-2.X.Y\src
  winmake /build release
  winmake /build debug

2 Build and run the test suite:
  cd \uimacpp-2.X.Y\src\test
  devenv test.sln /build release
  fvt

3 Build the documentation:
  Note: The documentation build requires Doxygen 1.3.6 or later.
  cd \uimacpp-2.X.Y\docs
  builddocs

4 Build the SDK tree:
  set MSVCRT_HOME to the directory with the required msvc*.dll files.
  set ACTIVEMQ_HOME if building the ActiveMQ service wrapper, deployCppService.

  cd \uimacpp-2.X.Y
  buildsdk "target_dir [clean]"

5 Package the SDK zipfile by creating a compressed folder of 
  target_dir\uimacpp into uimacpp-2.X.Y-bin.zip

6 Package a source zipfile by creating a compressed folder of the
  the directory containing the uimacpp source from git


----------------------------------------------
4. Building, testing and packaging on Mac OSX:
----------------------------------------------
Except for note below, building is the same here as outlined
in Building on Unix (section 2).

Make sure you have built and installed in your system all prerequisites, 
as stated in General (section 1).


4.1 Patch APR
-------------

For the Intel-based Mac OSX machines we have tested with, the APR function
to dynamically load shared libraries does not respect DYLD_LIBRARY_PATH.

A fix is to patch dso/unix/dso.c as follows:

26a27,31
>#if defined(DSO_USE_DYLD)
>#define DSO_USE_DLFCN
>#undef DSO_USE_DYLD
>#endif
>


4.2 Re-generated configure
--------------------------

In Mac OSX it is necessary to re-generate the configure file:

  ./autogen.sh


4.3 Executing configure
-----------------------

Mac OSX Sierra default GCC is not capable of building UIMACPP. As alternative, you can
install GCC-5 and pass it as an agument in configure command:

 CC=gcc-5 CXX=g++-5 ./configure <other parameters>

Make sure to pass the JDK Hearder path (--with-jdk) and the path of each dependency
(--with-<dep name> syntax).


4.4 Packaging UIMA C++ annotators:
On Mac OSX, the install names are embedded in the binaries.  Run the
following steps manually post build to neutralize the embedded name in
the UIMA C++ binary and to change the dependency path in the
annotator:
 
1) changing the install name in libuima, to neutralize it:

install_name_tool -id libuima.dylib $UIMACPP_HOME/install/lib/libuima.dylib

2) changing the dependency path in the annotator:

install_name_tool -change "/install/lib/libuima.dylib"
"/absolute_path_to_uimacpp_home/install/lib/libuima.dylib" MyAnnotator.dylib


----------------------------------------------------------------------------
5. Building the dependencies: APR et al, ICU, Xerses-c and Activemq-cpp
----------------------------------------------------------------------------

Download and build information for these libraries are at:
  APR      - http://apr.apache.org/
  ICU      - http://www.icu-project.org/
  XERCES   - http://xml.apache.org/xerces-c/
  ACTIVEMQ - http://activemq.apache.org/cms/download.html

ACTIVEMQ CPP library version 3.2 or higher is required to support
the ActiveMQ failover protocol and to support multi-byte payload data.
ACTIVEMQ CPP 3.2 and higher has a dependency on APR at version 1.3.8
or higher and APR-util 1.3.8.  (On Windows APR-util requires APR-iconv)


5.1 Building Dependencies on Unix/MacOSX
----------------------------------------
The directions for these components is straightforward. The UIMACPP
build expects to find headers in install_loc/include and libraries
in install_loc/lib.


5.2 Building Dependencies on Windows:
-------------------------------------
The build of dependent libraries on Windows is less consistent.
The APR components must be checked out and built in parallel 
directories (see apr.apache.org) and the libraries are expected 
to be located relative to %APR_HOME%.
ActiveMQ libraries are in %ACTIVEMQ_HOME%\vs2008-build\ReleaseDLL
and the headers are expected in %ACTIVEMQ_HOME%\src\main.

On Windows, buildsdk command tries to copy the msvc*.dll runtime libs from
C:\Program Files\Microsoft Visual Studio8\VC\redist\x86\Microsoft.VC80.CRT 
To override the location for MSCV redistributable libraries, use MSVCRT_HOME.

ActiveMQ-CPP - The UIMA C++ MSVC projects are Microsoft Visual Studio
8 (2005) projects.  The ActiveMQ CPP source distribution comes with
MSVC 8 (2008) project.  These can be down converted to MSVC 2005 by
following these step reproduced from
http://stackoverflow.com/questions/609419/how-do-i-downgrade-a-c-visual-studio-2008-project-to-2005

Put the following sed script in a file called downgrade_vc9_to_vc8.sed :
s#Version=\"9.00\"#Version=\"8.00\"#g
s#<ProductVersion>9.0.21022</ProductVersion>#<ProductVersion>8.0.50727</ProductVersion>#g
s#<TargetFrameworkVersion>v2.0</TargetFrameworkVersion>##g
s# ToolsVersion=\"3.5\"##g
s#MSBuildToolsPath#MSBuildBinPath#g

Run 
sed.exe -f downgrade_sln_vc9_to_vc8.sed vs2008-build/activemq-cpp.vcproj > vs2008-build/activemq-cpp2005.vcproj

The only activemq-cpp target needed by uimacpp is ReleaseDLL,
 e.g. devenv vs2008-build/activemq-cpp2005.vcproj /build ReleaseDLL
 
The three APR libraries can be built by launching aprutil.dsw and
building libaprutil or by following the instructions in Makefile.win.

XERCES and ICU
Binary distributions are available for Xerces and ICU.
Use only those built with a compatible version of Visual Studio!
Currently the SDK uses xerces-c_2 so if a higher version is 
installed the MSVC project files must be edited.


----------------------------------
6. UIMA C++ Release Compatibility
----------------------------------
There are two distinct features of UIMA C++ to consider when dealing
with release compatibility:

- The framework dynamically loads annotators which are user code. The
   annotators make calls to UIMA C++ APIs and are built with some
   version of the SDK. A possible scenario is for an application to
   run annotators that were built with different releases of UIMA C++
   SDK.
- The SDK depends on ICU, XERCES, APR and ACTIVEMQ-CPP and a release
   is built with a particular version of these.  Binary compatibility
   therefore also depends on the compatibility of these underlying
   libraries.  In particular, ICU and XERCES encode the major and
   minor release numbers in the APIs which restricts binary
   compatibility across releases of these libraries.  An application
   running UIMA C++ is restricted to running one version of the ICU
   library in a process and all annotators and underlying libraries
   must use the same ICU version.
   
In general, different UIMACPP releases are not binary compatible.
