For those of you that choose to use the GNU General Public License, my interpretation of the GNU General Public License is that no Perl script falls under the terms of the GPL unless you explicitly put said script under the terms of the GPL yourself. Furthermore, any object code linked with perl does not automatically fall under the terms of the GPL, provided such object code only adds definitions of subroutines and variables, and does not otherwise impair the resulting interpreter from executing any standard Perl script. I consider linking in C subroutines in this manner to be the moral equivalent of defining subroutines in the Perl language itself. You may sell such an object file as proprietary provided that you provide or offer to provide the Perl source, as specified by the GNU General Public License. (This is merely an alternate way of specifying input to the program.) You may also sell a binary produced by the dumping of a running Perl script that belongs to you, provided that you provide or offer to provide the Perl source as specified by the GPL. (The fact that a Perl interpreter and your code are in the same binary file is, in this case, a form of mere aggregation.) This is my interpretation of the GPL. If you still have concerns or difficulties understanding my intent, feel free to contact me. Of course, the Artistic License spells all this out for your protection, so you may prefer to use that. One last thing - The SAP RFCSDK is a prerequisite for this perl package to work. The RFCSDK is proprietrary software owned by SAP AG. For this reason I will not supply ANY component part of the RFCSDK with this perl package, and further more you must obtain it through the normal channels with SAP AG - ie. you must have a licensed SAP R/3 installation at your disposal. After all the legal stuff - Hello! Welcome to the SAP::Rfc perl package. This package is intended to facilitate RFC calls to an SAP R/3 system of release 3.1x and above. It may work for earlier versions but it hasn't been tested. The fundamental purpose of the production of this package, is to provide a clean object oriented interface to RFC calls from within perl. This will hopefully have a number of effects: (1) make it really easy to do RFC calls to SAP from perl in an object oriented fashion (Doh!) (2) promote perl as the interface/scripting/glue language of choice for interaction with SAP R/3. (3) make the combination of Linux, Apache, and perl the killer app for internet connectivity with SAP. (4) Establish a small fun open source project that people are more than welcome to contribute to, if they so wish. With this in mind - this package has been developed under Linux, so the installation is therefore focused on this. This does not mean that it will not work on other UNIX like flavours - to the contrary it probably will, it just hasn't been tested. The package has been compiled and run under Win32 - special attention needs to be paid to the options found in the Makefile.PL file. After the fundamental RFC interface has been developed, the intention is then to extend this to add interface discovery, and a BAPI abstraction layer - but this is down the track. SAP have kindly provided the RFCSDK for Linux on the OSS ftp service. This can be retrieved from sapserv3, currently in the "unsupported directory" - this should change before the end of 1999 to being fully supported. See OSS note 53459 for details. *Note: 29.11.2002 - this is old info from circa 1999 - I am currently using RedHat 8.0 and either the librfc or librfccm from R3 4.6C. This must be installed before you continue. I use Redhat 6.1 or Slackware 7.0 - other distributions will probably work, but take heed of the instructions provided with the rfcsdk rpm files. Once you have the rfcsdk installed carry on! Make sure that the LIBS and INC directive in the Makefile.PL points to the correct location of your OS's version of the rfcsdk -without this linking correctly nothing is going to work. After you have unpacked your kit, you should have all the files listed in MANIFEST. Installation In brief, the following should work on most systems: perl Makefile.PL make make test << provide all your host routing information. make install Cheers - Piers Harding - R/2 R/3 BASIS, IFACE, JAPH, whatever ... email: piers@cpan.org
