Welcome to the TTCN-3 parser!

This file describes how to compile the TTCN-3 parser source code.
If the description below is faulty or lacks some information, please
send a short email to 'schmitt@itm.mu-luebeck.de'.

Good luck!

********************************************************************

What you need to compile the TTCN-3 parser source code:

  - ANTLR 2.7.1 or higher (download for free at www.antlr.org)
  - An ANSI C++ compiler (e.g., gcc 2.95.2, or Sun CC 5.0/5.1)
  - A 'Make' tool (e.g., GNU make)
  - The TTCN-3 parser source code (of course :-))

Preparation for ANTLR:

  - Install ANTLR in a directory of your choice,
    e.g. '/home/user/programs/antlr'

  - Set the Java 'CLASSPATH' to the ANTLR directory.

    In a C shell (csh/tcsh) on UN*X, you have to enter

      setenv CLASSPATH ${CLASSPATH}:/home/user/programs/antlr

    In a Bourne shell (sh/bash), the following commands must be used:

      CLASSPATH=${CLASSPATH}:/home/user/programs/antlr
      export CLASSPATH

  - Set the environment variables CXX and CXXFLAGS according to your
    preferred C++ compiler and its options.

    In a C shell (csh/tcsh), you may select Sun CC as follows:

      setenv CXX CC
      setenv CXXFLAGS "-O +p +w2"

    Alternatively, gcc 2.95.2 can be chosen in a Bourne shell by

      CXX=g++; export CXX
      CXXFLAGS="-O -ansi -pedantic -Wall"; export CXXFLAGS

  - Enter directory '/home/user/programs/antlr/lib/cpp/src' and compile
    all '*.cpp' files (create a '.o' file for each of them)

    Typically, you invoke your compiler like follows:

      ${CXX} ${CXXFLAGS} -c -I.. -I. *.cpp

  - Link all generated '.o' files, i.e. create one big library file.

    When using Sun's CC, you have to invoke

      CC -xar -o libantlr.a *.o

    Object files generated by gcc can be linked with ar:

      ar -r libantlr.a *.o

  - For convenience, move 'libantlr.a' to subdirectory
    '/home/user/programs/antlr/lib/cpp/antlr'


Compilation of the TTCN-3 parser:

  - Download the latest source files from the CVS repository and put
    them all in one working directory

  - Make a subdirectory in the working directory which is identical
    to '/home/user/programs/antlr/lib/cpp/antlr'.

    There are two possibilities: Either copy the directory or (preferably)
    make a symbolic link to it:

      ln -s /home/user/programs/antlr/lib/cpp/antlr .

  - Apply the 'Makefile' provided with the TTCN-3 parser by running

      make TTCN3Parser

  - Start the TTCN-3 parser with

      ./TTCN3Parser --help
