Build and install Titan on Linux

1.Install required libraries: 
(examples are given for Ubuntu 12.04/14.04; for other Linuxes, pls. use the relevant library installation method)

sudo apt-get install g++ expect libssl-dev libxml2-dev libncurses5-dev flex bison
xutils-dev is needed by makedepend:
sudo apt-get install xutils-dev
The following packages may be needed for titan_eclipse/automatic_build:
sudo apt-get install ant xsltproc

2.Clone or update the titan directory from git into /home/<user_id>/titan.core

cd /home/<user_id>/
git clone https://github.com/eclipse/titan.core.git  titan.core

or

Update the already existing local repository:
cd /home/<user_id>/titan.core
git pull https://github.com/eclipse/titan.core.git

3. Configure the build 

cd titan.core

For open source users: check that MakefileFOSS.cfg is present and has the following content:
cat MakefileFOSS.cfg

# Configurations for the Free Open Source Software version
LICENSING := no
USAGE_STATS := no

If you want to use your build within the Ericsson domain: delete MakefileFOSS.cfg
This will enable Ericsson internal-only licensing and statistics.
 
GEN_PDF set to yes will convert Word documents to PDF using a web service available within Ericsson only.
Alternatively, one can install libreoffice and convert the documentation files as below:

cd titan.core/userguide
libreoffice -convert-to pdf *.doc *.docx

Several other build options are possible; for details on options please read through the Makefile.cfg.
Options can be overridden by the content of  a file named Makefile.personal which can be used to 
adapt to local installation directories, change config options etc.
Below, a small number of typical scenarios are presented.

Note: For each scenario below on Raspberry Pi "-fsigned-char" needs to be added to compiler flags in Makefile.personal:

COMPILERFLAGS := -Wall -fsigned-char


a) JNI  disabled, gcc compiler (default)

The JNI interface is used by the Eclipse Titan Executor or by the Java Executor API.
If you don't need them, Titan can be compiled without JNI. 

Create ~/titan.core/Makefile.personal to override settings in Makefile.cfg with the following content:
(replace paths with values relevant to your installation)

TTCN3_DIR := /home/<user id>/titan.core/Install
OPENSSL_DIR := /usr
#JDKDIR := /usr/lib/jvm/java-7-openjdk-amd64
XMLDIR := /usr
JNI := no
GEN_PDF := no

b) JNI  disabled, clang compiler ver. 3.8

Create ~/titan.core/Makefile.personal to override settings in Makefile.cfg with the following content:
(replace paths with values relevant to your installation). 

TTCN3_DIR := /home/<user id>/titan.core/Install
OPENSSL_DIR := /usr
#JDKDIR := /usr/lib/jvm/java-7-openjdk-amd64
XMLDIR := /usr
JNI := no
GEN_PDF := no
CXX := clang++-3.8
CC := clang-3.8 


c) JNI  enabled, gcc compiler (default)

install JDK   into /home/<user id>/jdk

Create ~/titan.core/Makefile.personal to override settings in Makefile.cfg with the following content:
(replace paths with values relevant to your installation).

TTCN3_DIR := /home/<user id>/titan.core/Install
OPENSSL_DIR := /usr
JDKDIR := /usr/lib/jvm/java-7-openjdk-amd64
XMLDIR := /usr
JNI := yes
GEN_PDF := no

d) For Alpine Linux, an appropriate flag has to be set:

:
ALPINE_LINUX := yes
:


4. Run make

make

5. Set environment variables

setenv TTCN3_DIR /home/<user id>/titan.core/Install
setenv PATH /home/<userid>/titan.core/Install/bin/:${PATH}
setenv LD_LIBRARY_PATH /home/<userid>/titan.core/Install/lib:${LD_LIBRARY_PATH}

for csh

or 

export TTCN3_DIR=/home/<user id>/titan.core/Install
export PATH=/home/<userid>/titan.core/Install/bin/:${PATH}
export LD_LIBRARY_PATH=/home/<userid>/titan.core/Install/lib:${LD_LIBRARY_PATH}

for bash

6. Run make install

make install

This will install Titan into  /home/<user id>/titan.core/Install


7. Optionally , run function/regression tests

cd /home/<user id>/titan.core/function_test

in the following Makefiles 

BER_EncDec/Makefile
XER_EncDec/Makefile
Text_EncDec/Makefile
RAW_EncDec/Makefile

edit the value of XMLDIR to match your installation values 

run the tests

make

( or make |& tee outputfile if you want to save the output for verification)

cd /home/<user id>/titan.core/regression_test
make run

( or make run |& tee outputfile if you want to save the output for verification)

These tests might run for half an hour (regr.tests)  to two hours (func.tests)

8. Optionally, copy Titan into its final directory.
From here on, you can continue with the Titan installation guide, see /Install/docs, to set/change environment variables etc.
and then, optionally, the Eclipse installation guide.
