Help for newbie

Hi, my company has been using both PHP and SAP for a few years. I have some PHP experience and experience with MM. I did do some basic ABAP... We are very interested in interfacing SAP and PHP. I am not very familiar with the RFC function in SAP. My question... how do I know if I already have the SAPRFC SDK 6.20 or.. if I don't where do I get it? I have been searching the SAP marketplace, but its information overload!!

Would appreciate any advice, thanks

    Hi Natalie,

    The following is the homepage of SAPRFC on sourceforge (http://saprfc.sourceforge.net/).

    In the requirements section it points you in the direction of the part of service marketplace where you can find the SDK:

    you can find it on http://service.sap.com/swdc under Patches for SAP WEB AS - SAP WEB AS 6.20 - SAP RFC SDK

    Here are some more detailed directions:

    From the link:

    http://service.sap.com/swdc

    In the tree on the left select the node

    SAP Software Distribution Center->Download->Support Packages and Patches->Entry by application group

    From the result list select Netweaver.

    Now select SAP NetWeaver components ( < SAP NW 04 )

    Now select SAP WEB AS

    Now select SAP WEB AS 6.20

    You will see the SAP RFC SDK in the result list.

    Regards

    John

    We are now encountering some installation problems.

    We are on a RedHat Linux platform with apache 2. The other ingredients are

    - rfcsdk 620 non unicode extracted to /usr/sap/rfcsdk

    - saprfc 4.3.3

    - php 4.3.10 with saprfc in php_4.3.10/ext/saprfc

    In trying method 1 (buildconf --force and ./configure, make, make install) it is failing with:

    [root php-4.3.10]# rm ./configure

    [root php-4.3.10]# ./buildconf --force

    Forcing buildconf

    using default Zend directory

    rebuilding configure

    rebuilding main/php_config.h.in

    [root php-4.3.10]# ./configure --with-saprfc (for simplicity)

    <deleted - no errors>

    [root php-4.3.10]# make

    <deleted - error....>

    functions.lo -lrfc -lresolv -lm -ldl -lnsl -o sapi/cgi/php

    /usr/bin/ld: cannot find -lrfc

    collect2: ld returned 1 exit status

    make: *** [sapi/cgi/php] Error 1

    [root php-4.3.10]

    Can anybody hint what I am doing wrong?

    Is it correct that the 40 meg rfc file downloaded from sap should be just extracted to /usr/sap/rfcsdk?

    I have also tried the ./configure/make/make install of saprfc and it fails with along the procedure with:

    checking if the linker (/usr/bin/ld) is GNU ld... (cached) yes

    checking for BSD-compatible nm... (cached) /usr/bin/nm -B

    checking whether ln -s works... (cached) yes

    ./ltconfig: ./ltconfig: No such file or directory

    configure: error: libtool configure failed

    Thanks for any input.

    • The error you are seeing:

      /usr/bin/ld: cannot find -lrfc

      collect2: ld returned 1 exit status

      is indicative of the rfc library not being in the search path for the build script. It may well be that the library is in /usr/sap/rfcsdk.

      I have not personally tried to run these build scripts, but it may be that you also need to pass an argument (possibly with -L) to augment the library search path. Alternatively it may be possible for you to add the path to the environment variable LD_LIBRARY_PATH.

      I will try to get hold of the files and build it myself, that way I can provide a more detailed answer.

      Regards

    • I just successfully ran the build using a similar setup to you. I have SUSE Linux 9.1. I installed php 4.3.10 in a user directory. I then installed saprfc 1.3.3 in the <phpsrc>/ext directory as saprfc.

      I installed the SDK in /usr/sap/rfcsdk. This directory has the subdirectory lib containing the rfc library.

      I then ran:

      rm ./configure

      ./buildconf --force

      ./configure --with-saprfc

      make

      I did not have to do anything special to pick up the rfc library.

    Hello John,

    I tried several ways of helping it to see the /usr/sap/rfcsdk files but the compile fails with the same error. Incidentaly, I didn't find -L as being an option for make.

    Pity that this isn't working out for us. But let me know if you have any other detailed instructions.

    thanks

    The other suggestions haven't worked. If this was so easy for you, I must have some wrong files.

    • It looks like you have the unicode version of rfcsdk installed.

      I would suggest that you get the non unicode version from service.sap.com and install that one.

      In my /usr/sap/rfcsdk/lib directory I have librfc.a and librfccm.so. These are the two library files. When you get the error it is because the loader is looking for librfc.a. In your install you have librfcu.a which I assume is the unicode version.

      When you download the rfcsdk you have the following 2 options for 6.20 WAS:

      SAP RFC SDK 6.20

      SAP RFC SDK 6.20 UNICODE

      Make sure you get the first one.
