OpenH323 Library ================ The OpenH323 project aims to create a full featured, interoperable, Open Source implementation of the ITU H.323 teleconferencing protocol that can be used by personal developers and commercial users without charge. OpenH323 development is coordinated by an Australian company, Equivalence Pty Ltd (http://www.equival.com), but is open to any interested party. Commercial and private use of the OpenH323 code, including use in commercial products and resale, is enouraged through use of the MPL (Mozilla Public license). For more details see http://www.openh323.org You can subscribe to the mailing list at http://www.openh323.org/list.html Frequently asked questions are answered at http://www.openh323.org/faq.html Building the OpenH323 Code ========================== This page describes how to compile the OpenH323 code release. Note these instructions will always refer to the latest snapshot available on the download page. The OpenH323 source will have been compiled and tested under Linux x86, and Windows NT. If it does not compile for you then the problem is likely to be a setup/configuration problem with your system and not a problem with the source code itself. The libraries and applications should also compile on Windows 95/***, BeOS (thanks Yuri!), Linux PPC, FreeBSD x86, OpenBSD x86 (thanks Roger!) and Solaris Sparc & x86. They are not automatically compiled on every release however so there could be problems, but the chances are that there aren't. Note also that not all of these platforms may have ports of the sound interface. We are also happy to port it to other Unix flavours providing people out there can provide an account and a fair bit of disk space! These instructions should contain all of the steps need. If you have a problem, please double check that you have performed ALL of the steps below, particularly setting the include file paths under MSVC. Some of the more common errors are described below. If you get a lot of compile or link errors, then the chances are that you have missed something in the list. If you are positive that something is wrong and you have followed the instructions, then send an e-mail to the mailing list, and we'll answer it for everyone to see. Bear in mind that the first question asked will be "did you follow the instructions". Windows ------- 1. Download the pwlib_1.xx.zip and openh323_1.x.zip files from the OpenH323 download page. 2. Extract the pwlib_1.xx.zip file somewhere eg c:\, making sure the directory structure is preserved. 3. Start MSVC (v5 or v6). If you have another compiler you are on your own! Go into the Tools menu, Options item, Directories tab and add to the beginning of the Include files path (note the order is important!): C:\PWLib\Include\PwLib\MSWIN C:\PWLib\Include\PtLib\MSOS C:\PWLib\Include C:\OpenH323\Include and add to the Lib Files path and the Executable Files path the following: C:\PWLib\Lib C:\OpenH323\Lib Also make sure these directories are in your PATH environment variable. 4. Note you will need bison and flex to compile the system. You can get a copy from the openh323 site, follow the instructions included in that package for setting it up and put the executables (Note they should be called bison.exe and flex.exe) somewhere in your path. 5. Open the pwlib.dsw file in the pwlib top directory. 6. Use the Batch Build command and build the "ASNParser - Win32 Release", "pwtest - Win32 Release" and "pwtest - Win32 Debug" targets. Make sure all other targets are not checked. 7. Extract the contents of the openh323_1.x.zip file somewhere. 8. Use the OpenH323.dsw file to build the OhPhone code. 9. Run the program, and you are on your own! Unix ---- 1. Download the pwlib_min_1.xx.tar.gz and openh323_1.xx.tar.gz files from the OpenH323 download page. 2. Extract the pwlib_min_1.xx.tar.gz somewhere, preferably in your home directory, eg: cd tar -xzvf pwlib_min_1.14.tar.gz This should result in a ./pwlib directory tree. 3. If you have not installed PWLib in your home directory (~/pwlib) then you will have to define the environment variable PWLIBDIR to point to the correct directory. Also make sure you have added the $PWLIBDIR/lib directory to your LD_LIBRARY_PATH environment variable if you intend to use shared libraries (the default under Linux). There are examples for sh/bash and csh/tcsh below. 4. Build the debug and release versions of the PWLib library as follows: cd $PWLIBDIR make both This may take some time. Note, you will need GNU make (>=3.75), bison(>=1.25) and flex (>=2.5.4) for this to compile, most Unix systems have these packages. WARNING: there is a bug in some of the bison.simple files, see below for details. If you are getting huge numbers of errors from make then you are probably not using the GNU make. FreeBSD and OpenBSD users must install gmake and use gmake instead of make in these instructions. If the errors are during the compile, then it is likely your platform is not supported, or you have incorrectly set the OSTYPE and MACHTYPE variables. There will be a large warning printed about this, don't ignore it! 5. Extract the contents of the openh323_1.x.tar.gz file somewhere, eg: cd tar -xzvf openh323_1.1alpha1.tar.gz 6. If you have not installed OpenH323 in your home directory (~/openh323) then you will have to define the environment variable OPENH323DIR to point to the correct directory. Also make sure you have added the $OPENH323DIR/lib directory to your LD_LIBRARY_PATH environment variable if you intend to use shared libraries (the default under Linux). There are examples for sh/bash and csh/tcsh below. 7. Build the H323 bootstrap code. This will automatically build the ASN compiler (in the $PWLIBDIR/tools/asnparser directory), though this should have already been built previously. Enter: cd $(OPENH323DIR) make opt This may take some time, especially with the h245_*.cxx and h225.cxx files. You may also need to add more swap space - ***M of real memory and ***M of swap might just be enough, if your machine does nothing else! Some people have reported needing as much as 128M of swap - if your compiler bombs out with a "virtual memory exhausted" error compiling h245_*.cxx and h225.cxx, then increase your swap space. 8. The result should be an executable called simph323, which will be located in a directory dependent on the platform, eg sample/simple/obj_linux_x86_d. To run it, use the following command: ./sample/simple/obj_linux_x86_r/simph323 and you should get the usage help text. 9. Now you're on your own! Common errors ------------- Here are common errors you might encounter for both Windows and Unix builds. An error like: "Makefile", line 175: Missing dependency operator "Makefile", line 177: Need an operator "Makefile", line 179: Missing dependency operator "Makefile", line 181: Need an operator "Makefile", line 183: Missing dependency operator "Makefile", line 185: Need an operator Indicates you are using BSD Unix's Make command. You need to use gmake (GNU Make). Thinking there are missing files. A number of files, eg h235.h, h225.h etc, are generated files that are created during the build process. If they are missing then something went wrong with the creation of the asnparser or your installation of flex/bison. An error like: /home/newbie/pwlib/tools/asnparser/obj_linux_x86_r/asnparser: error in loading shared libraries: libpt_linux_x86_r.so.1: cannot open shared object file: No such file or directory Indicates you have not set the LD_LIBRARY_PATH environment variable. There are examples for sh/bash and csh/tcsh. An error like: Linking... LINK : fatal error LNK1181: cannot open input file "ptlib.lib" Error executing link.exe. Indicates you have not set the paths in MSVC directories. An error like: Performing Bison Step c:\tools\share\bison.simple: No such file or directory C:\PWLIB\TOOLS\ASNPAR~1\BISON.EXE: Cannot move asn_grammar_tab.c - No such file or directory Cannot move asn_grammar_tab.h - No such file or directory Indicates you have not installed bison correctly. In particular the bison.simple file must be available to bison. Check the bison documentation for details on this. Attempting to compile GUI systems under Unix. There are a number of partial implementations of the GUI code in the $PWLIBDIR/src/pwlib directory tree. These are not required to get the OhPhone application compiled. If you get those systems from the CVS then you are basically on your own. Do not ask for support unless you intend to help with the implementation! Example environment for sh/bash ------------------------------- PWLIBDIR=$HOME/pwlib export PWLIBDIR OPENH323DIR=$HOME/openh323 export OPENH323DIR LD_LIBRARY_PATH=$PWLIBDIR/lib:$OPENH323DIR/lib export LD_LIBRARY_PATH Example environment for csh/tcsh: setenv PWLIBDIR $HOME/pwlib setenv OPENH323DIR $HOME/openh323 setenv LD_LIBRARY_PATH $PWLIBDIR/lib:$OPENH323DIR/lib Bison problem under Unix ------------------------ The bison.simple file on many releases will not compile with the options used by the PWLib getdate.y grammar. The options are required to make the date parser thread safe so it is necessary to edit the bison.simple file to fix the problem. The file is usually at /usr/lib/bison.simple but in the tradition of unix could actually be anywhere. We leave it up to you to find it. The code: /* Prevent warning if -Wstrict-prototypes. */ #ifdef __GNUC__ int yyparse (void); #endif should be changed to /* Prevent warning if -Wstrict-prototypes. */ #ifdef __GNUC__ #ifndef YYPARSE_PARAM int yyparse (void); #endif #endif To prevent the incorrect function prototype from being defined. The getdate.y should then produce a getdate.tab.c file that will actually compile. Licensing --------- The bulk of this library is licensed under the MPL (Mozilla Public License) version 1.0. In simple terms this license allows you to use the library for any purpose, commercial or otherwise, provided the library is kept in tact as a separate entity and any changes made to the library are made publicly available under the same (MPL) license. It is important to realise that that refers to changes to the library and not your application that is merely linked to the library. Note that due to a restriction in the GPL, any application you write that uses anything another than GPL, eg our library with MPL, is technically in breach of the GPL license. However, it should be noted that MPL does not care about the license of the final application, and as only the author of the GPL application is in breach of his own license and is unlikely to sue themselves for that breach, in practice there is no problem with a GPL application using an MPL or any other commercial library.
