1 Introduction
1.1 Overview
This document describes obtaining the TITAN TTCN-3 Test Executor
software, installing the Test Executor and all of its components, setting the
user environment, and licensing mechanism.
1.2 Target Groups
This document is for all audience who intend to create and execute
simulations.
1.3 Typographical Conventions
This document uses the following typographical conventions:
• Bold is used to represent graphical user interface (GUI) components
such as buttons, menus, menu items, dialog box options, fields and
keywords, as well as menu commands. Bold is also used with ’+’ to
represent key combinations. For example, Ctrl+Click
• The ‘/’ character is used to denote a menu and sub-menu sequence.
For example, File / Open.
• Monospaced font is used represent system elements such as
command and parameter names, program names, path names, URLs,
directory names and code examples.
• Bold monospaced font is used for commands that must be entered
at the Command Line Interface (CLI), For example, ttcn3_start
1.4 Prerequisites
The supported platforms are Solaris, Linux and Cygwin (on Windows
platforms).
The following are required for proper operation of the TITAN:
• Openssl-devel 0.9.8k or higher
• Libxml2-devel 2.7.1 or higher
• JDK 1.5.0_10 or later (only required if the JNI-based executor in the
Executor plug-in is used. JNI cannot be used on Cygwin.)
Note: If the platform has other, but compatible, version of above tools, TITAN
will be built with those.

On Linux, the platform-supplied versions of OpenSSL-devel and libxml2-devel
are used. OpenSSL is usually installed by default. The libxml2 package and
the development packages may need to be installed manually.
The development packages should be called openssl-dev (or -devel) or
libopenssl-dev (or -devel) and libxml2-dev (or -devel) respectively.
To deploy the prerequisites is special on Cygwin therefore it is discussed
below.
1.5 Installing Prerequisites on Cygwin (on Windows)
To deploy the prerequisites is special on Cygwin therefore it is discussed
below.
Titan is always built on the newest Cygwin version available.
• If Cygwin has been installed already, refresh your Cygwin installation.
Start the Cygwin setup utility (see below). It will refresh your installed
Cygwin packages to the newest versions.
• If Cygwin hasn’t been installed yet:
1 Download and execute the latest Cygwin installer utility depending on
your platform and the Titan package to be downloaded:
32-bit version: https://cygwin.com/setup-x86.exe
64-bit version: https://cygwin.com/setup-x86_64.exe
2 Select Install from Internet (recommended to save local disk place)
3 Choose Cygwin installation root directory (C:\cygwin is recommended).
4 Select All users or Just Me.
5 Select “Local Package Directory” (typically the same directory, where the
setup…exe Cygwin installer utility is stored).
6 Use Internet Explorer Proxy Settings (recommended).
7 Select a download mirror site.
8 In the package selection dialog you can select different views to find the
required packages easier and you can search the packages via the
search field. The Cygwin installer will automatically select the packages
which the manually selected ones are depending on. Do not deselect any
automatically selected package!
There are three hierarchical levels of minimally required packages,
depending on Your task:
8.1 test execution only (from command line or from Eclipse Titan
Executor):
Base: <All packages> (Default setting of the installer)
Net: openssl
Tcl: expect

8.2 Test case development: in addition to the above select the following
packages:
Devel: binutils
Devel: gcc-g++
Devel: make
Libs: libxml2-devel
Net: openssl-devel (automatically installs Net:openssl as well, if
selected
8.3 To compile your own Titan Cygwin binary: in addition to the above,
select the following packages:
Devel: bison
Devel: ctags (optional)
Devel: diffstat
Devel: flex
Devel: gcc-core
Devel: perl
Devel: git
Editors: <any editor of your preference> e.g vi, nedit, xemacs, gedit,
nano and so on
Libs: libncurses-devel
Libs: libreadline-devel
Libs: libexpat1
Libs: libiconv, libiconv-devel, libiconv2
8.4 To contribute to Titan, test port or protocol module development
Devel: git-review
If, after selecting the required packages and clicking on the “Next”
button, a “Resolving Dependencies” window lists further required
packages, ensure that the “Select required packages
(RECOMMENDED)” checkbox is checked and click on the “Next”
button.
9 Select the “Create” icon on the Desktop checkbox
10 (Optional)
Your "unix" home directory, by default is: <your cygwin installation
directory>/home/<yourUserId>. If you are (also) working in command line
mode, it is a good practice to change this to the folder where your TTCN-3
projects are located. Edit the file <your cygwin installation
directory>/etc/passw: In the line: ourUserId>:unused:<xxxxxx>:<yyyyy>:U<yourDomain>\<yourUserId>, S-1-5-21nnnnnn...nnnnnn:/home/<yourUserId>:/bin/bash replace
"/home/<yourUserId>" with the folder of your preference.
Note: you can access all W indows drives from Cygwin as
/cygdrive/<windowsDriveLetter>".
Example: to set your "unix" home directory to the "My_Home" folder within
your Windows Documents folder, you should replace
"/home/<yourUserId>" by

"/cygdrive/c/Users/<yourUserId>/Documents/My_Home"
WARNING: The path of your "unix" home directory shall not contain any
space!
Note: It is not a requirement, but is a kind of best practice to place Titan
into a subfolder within your "unix" home directory.
11 When installation is finished, add the
$CYGWIN_INSTALL_DIRECTORY\bin and
$CYGWIN_INSTALL_DIRECTORY\usr\bin directories to the PATH
environment variable of Windows, so Eclipse will access the shell
commands.
For example, if the cygwin root is "C:\cygwin64" then "Path" should
contain "C:\cygwin64\bin;C:\cygwin64\usr\bin".
12 To check if your installation is correct, open either a Cygwin shell (use the
desktop icon created during Cygwin installation or start
bash.exe
from the Windows Start menu) or start cmd.exe from the Windows Start
menu and type:
bash.exe
2 Installing from a pre-built binary package
This chapter describes obtaining the software and installing it.
2.1 Downloading the Software
The Titan package can be installed from the provided download sites.
Download the Titan package for your platform, OS and GCC version from the
provided download sites:
• For Ericsson users only: http://ttcn.ericsson.se/download .
The usage of this version is conditioned by the presence of a license file
and supported by the Titan support team.
• For users outside Ericsson:
https://projects.eclipse.org/projects/tools.titan/downloads. This version is
licensed under the Eclipse Public License.
A binary distribution, suitable for the used operating system (Solaris, Linux,
FreeBSD), and for a C++ compiler, in a tar-gzip archive will be received. For
Windows
1
users there is no pre-built version, but compiling the open-source
version is possible.

Warning: the version of C++ compiler used is important. If the version
difference between the system’s compiler and the compiler that the basic
TTCN–3 library was built with is large enough, the linking of executable test
suites will fail with strange error messages. The reason is the different
mapping of C++ class and (polymorphic) member function names into linker
symbols.
For example, this problem persists between versions 2.8.x and 2.95.x of
GCC. Different C++ compilers (e.g. Sun Workshop and GCC) are, of course,
totally incompatible.
The solution for this problem is to use nearly the same version of the C++
compiler as the binary package was built with.
Binaries for other operating systems or C++ compilers are available only on
request.
2.2 Installing the Package
No administrator (root) privileges are required for installation, but the install
directory must be readable for all users of the test executor. Perform the
following steps to install TITAN:
1 Create an empty directory, for example, /usr/local/TTCN3 or
/home/<UserId>/TTCN3. This directory will be referred as
$TTCN3_DIR in the further sections of this document.
2 Copy the .tgz file into this directory.
3 Unpack all files from the archive using any of the following commands
(assuming GNU tar):
tar xvzf ttcn3-<version>-<platform>-<compiler>.tgz
or
gzip -dc ttcn3-<version>-<platform>-<compiler>.tgz |
tar -xvf -
The following sub-directories are created:
• bin contains the executable programs: The Compiler, the Makefile
Generator, the Main Controller for parallel test execution and two log
formatter utilities.
• etc contains a demo license key, which enables to use the parser
parts of the Compiler by any user on any host, that is, without C++ code
generation. The installation can be tested with this demo key until the
personalized license key is received.
• include contains the C++ header files needed to compile the
generated C++ code.
• lib contains the pre-compiled Base Library for use with the generated
C++ code both for single and parallel mode in static and dynamic
linking

formats.

• man contains UNIX manual pages (for the Compiler and the Makefile
Generator).
• demo contains a simple TTCN–3 test suite (” Hello, world!”) together
with a sample test port and a compiled executable.
• doc contains this documentation in PostScript and PDF formats.
To complete the TITAN TTCN–3 Test Executor installation, some
environmental variables should be set and the login script should be modified.
Note: The C++ source code generated by this version (patch level) of
Compiler is not compatible with older versions of TTCN–3 Base Library and
vice versa.3
If upgrading TITAN from an older version, all modules of existing test suites
must be re-translated with the new compiler in order to make them running
with the new libraries.
It is recommended to make a backup copy of the older version of the
distribution. There are some minor incompatibilities in the compiler’s grammar
that may cause many syntax errors in TTCN–3 modules that were translated
correctly with earlier versions.
2.3 Install TITAN with Clang
Currently it is experimental to use TITAN with clang on Ubuntu operating
system. It was tested only on Ubuntu. In order to use TITAN with clang on
Ubuntu some steps must be done:
1. Install clang-3.8 (3.8 is the required version).
2. Go into your TITAN installation directory and open (or create) the
Makefile.personal file and add the following lines:
CXX := clang++-3.8
CC := clang-3.8
3. If TITAN is already compiled run make distclean command
4. To compile TITAN with clang run make and make install commands.
There are some important notes about using clang with TITAN:
• The C++ source code generated and TITAN must be compiled with the
same version of clang. See section 2.2 note.
• Makefiles of TTCN-3 projects must be modified by hand
(replace CXX = g++ with CXX = clang++3.8). Or regenerated using
makefilegen, to use clang compiler. TITAN’s makefilegen can detect if it
was compiled with clang and will generate makefiles with clang as default
C++ compiler.
• Required clang version is 3.8.

3 Building Titan from source code
3.1 Obtaining the source code to your local machine
The name of the source code repository of Titan is titan.core in the github.
Follow steps as follows.
1 First time execute these commands:
cd ~/git
git clone https://github.com/eclipse/titan.core.git
This way a folder “titan.core”, the “titan repository” will be created with the
TITAN source code and build system.
To update the already existing repository execute these commands:
cd ~/git/titan.core
git pull https://github.com/eclipse/titan.core.git
2 Follow the instructions in the file “titan.core/README.<your
platform>”
3 Continue with the next paragraph of this document.
4 Setting the User Environment
This chapter describes the environment variables that must be set, and the
modification of the user login scripts.
4.1 Environment Variables
The following environment variables should be set:
• With system administrator privileges, set the $TTCN3_DIR environment
variable in the common /etc/profile and add the
$TTCN3_DIR/bin directory to the system paths.
• All tools of TITAN, including the Executable Test Suites, require a
shared library of OpenSSL (libcrypto.so) for execution.
To avoid incompatibilities, the suitable shared object file is provided in
$TTCN3_DIR/lib, so add $TTCN3_DIR/lib to the
LD_LIBRARY_PATH environment variable.
Warning: If this step is not performed, the compiler will not start!
• Add $TTCN3_DIR/man to the $MANPATH environment variable to
reach the manual pages directly.
• If there is no valid license key, refer to Licensing.
If upgrading from an older version with a license key valid for this
version, skip this step.

• To run TITAN, ensure that the $TTCN3_DIR environmental variable
has been set, for example, assuming a tcsh as login shell:
setenv TTCN3_DIR /usr/local/TTCNv3
• To use the TTCN–3 keyword help feature in the GUI with a web
browser other than the default Netscape, it is necessary to set the
$TTCN3_BROWSER environmental variable, for example, to specify
Opera, type the following at the C-shell:
setenv $TTCN3_BROWSER opera
After setting the environmental variables, the TITAN TTCN–3 Test Executor
installation is complete.
4.2 Modification of the User Login Script
The following examples provide some help in modifying the login scripts.
Example modifications of login script assuming bash as login shell:
TTCN3_ DI R=/usr/loc al/ TTCNv3
PATH=$ TT CN3_DIR/bi n:$ PATH
LD_LIB RA RY_PATH=$T TCN 3_DIR/lib :$LD_LIB RA RY_PATH
MANPAT H= $MANPATH:$ TTC N3_DIR/ma n
TTCN3_ LI CENSE_FILE =/h ome/tmpus r/l icense.dat
export T TCN3_DIR P ATH LD_LIBRA RY_ PATH MANPA TH TTCN3_LIC ENS E_FILE
Example modifications of login script assuming tcsh as login shell:
setenv T TCN3_DIR / usr /local/TT CNv 3
setenv PATH ${TTCN 3_D IR }/bin:${PATH}
setenv L D_LIBRARY_ PAT H ${ TTC N3_DIR}/li b:${L D_ LIB RARY_PA TH}
setenv MANP AT H $ {MANPAT H} :${ TTCN3_D IR} /m an
setenv T TCN3_LICEN SE_ FILE /hom e/t mpusr/lice ns e.dat
4.3 Modifying Makefile Library
Make sure that the Makefile contains the following highlighted part:
SOLARIS8_LIBS = - lxnet -lxml2 -lresolv -lnsl -lsocket
LINUX_LIBS = -lxm l2 -lpthread -lrt

5 Licensing
This chapter describes how to obtain and install a TITAN license key.
From version 1.1.pl8, TITAN can be used only with a valid license key.
5.1 Obtaining License Key (Only for Ericsson users)
The license keys are free of charge and can be ordered via an HTML form
on the following URL:
Request a Titan licence at:
https://ericoll.internal.ericsson.com/sites/Titan/Pages/TitanLicenses.aspx
The personalized license key is a simple ASCII text file, which is sent as an email attachment.
Example of license file:
-----B EG IN TTCN-3 LICENSE FI LE -----

-----E ND TTCN-3 LICENSE F ILE -----
The license key contains the following information encoded in PEM format of
OpenSSL library:
A unique identifier (integer number).
If the license needs to be renewed or there are problems with licensing, refer
to this Unique ID.
• Personal data: user’s name, e-mail address, company’s name and
department.
• The time interval of the license key validity.
• The host ID of the computer where the license is valid on (optional).
• The login name that is allowed to use the tool with this key (optional).
• The type of limitation, that is, host ID, login name or both.
• The version interval of the Test Executor that the license key is valid for.
• The list of features that are enabled by this key (in a bitmask).
• DSA digital signature

5.2 Installing the License Key
Perform the following steps to install the license key:
• Save the license key somewhere in the user home directory.
The recommended name for it is license.dat, but it can be named
alternatively
• It is advised to change its permissions to read-only in order to avoid
accidental modification or erasing.
• Set the TTCN3_LICENSE_FILE environment variable to point to the
license file with full path name. Add this command to the login script to
do this step automatically for each login.
• Check the validity of the license by issuing
$TTCN3_DIR/bin/compiler -v.
The compiler will print its version and the information contained in the
license file. Also it checks the validity of the license key.
