RFC SDK linking errors

I tried the HP-UX 6.40 and 7.10 versions with the same result. So I scanned /usr/lib for one of the symbols and came up with libCsup and libnisdb. Adding -lCsup cleared up the missing symbols.
Still don't understand the Linux problem...

Please look at these...
INTEGRATION_DIRECTORY_HMI: Connection fails
ICM_HTTP_CONNECTION_FAILED
SAF - ICM_HTTP_CONNECTION_FAILED
HTTP adapter setup
Think these should help you out!

IPhone SDK - Linking error with CLLocationManager

Hello.
I have a linking error when I try to use thr CLLocationManager in my iPhone application by using the example of source code given in the Developer Center.
I have the following error : ".objcclass_nameCLLocationManager", referenced from literal-pointer@_OBJC@__clsrefs@CLLocationManager in localisation.o
symbol(s) not found.
Do you have an idea ?
Thank you for your answer.
Patrick Schevenels.

Just for clarification, there's a flood of developers now purchasing Macs to code for the iPhone platform. For those of you new to Xcode, you add a framework by doing the following:
1. Open your iPhone project in XCode
2. In the project window, ctrl+click (or right-click if you have 2-button mouse) on 'Frameworks' folder > Add > Existing Frameworks
3. Navigate to /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.0.sdk/System/Li brary/Frameworks/CoreLocation.framework
4. Click 'Add' button
5. Compile
Also, for anyone coming for the ActionScript Java or C# world, I've been blogging on transitioning to iPhone OS development platform.

Hi,
This problem usually occurs when you are installing from an ISO build for a different architecture.
Windows SDK now have different ISO’s for different architectures. Please download the correct ISO based on your system platform and architecture type.

NW RFC SDK: No more human-readable RFC error messages?

I'm converting my program from the classic RFC SDK to the NetWeaver one.
Apparently, the RFC_ERROR_INFO.message value is no longer filled with the proper human-readable error message as it used to be.
Eaxmple: trying to create a function description for a non-existant function
Classic SDK: "Function module "Z_MYFUNC" not found."
NetWeaver SDK: "ID:FL Type:E Number:046 Z_MYFUNC"
I don't see how to get the old message back. Can anyone help? Thanks!

I am using nwrfcsdk in c directly, I have encountered some other issues, you may
check the nwrfcsdk init release blog by Ulrich via
/people/ulrich.schmidt/blog/2007/05/10/sap-netweaver-rfc-sdk
May be the patch 1 have solved this issue already.

Link errors when building with librfc.a from RFCSDK 7.00 for z/OS 32 bit

There is a disparity between the documentation and the contents of the RFCSDK for z/OS 32 bit.
The documentation included with the SDK is for older versions of the RFCSDK and discusses the librfc dll and librfc.x sidedeck file. However, the new SDK no longer includes the rfclib dll and rfclib.x sidedeck file. Instead, it includes the librfc.a library file.
Simply compiling and linking with librfc.a is not enough. Numerous link errors occur. It appears that an SAP specific define must be required in order to properly decorate rfc functions. Below is an excerpt of the link errors I am receiving.
Any help on this issue would be greatly appreciated.
Thanks,
Bob

Here is a link to the info on how to access the 4200 set up pages and how to do Port Forwarding with it
http://portforward.com/english/routers/port_forwarding/Siemens/4200/iChat.htm
Use the Access info and then see if you have it doing UPnP to open the ports.
If it is then the Port Forwarding does not need setting.
Next, if you did originally set it to do Port Forwarding this should have pointed to an IP (The one your computer has/had)
Check the Port Forward that is set is pointing to the IP the computer has now by Looking in System Preferences > Network
QUite a way done the log your end suddenly switches the port it sends the SIP part of the invite on

This is not an iChat port and it messes up where iChat then says to send the Video and Audio data.
The log from the other end implies the ports are not even open.

SAP RFC SDK 7.10 Compilation Issues

Hello ,
We have a Pro*C program that is using the RFC SDK 7.10
When we are compiling our program with Pro*C Compiler in HP UX 11iv2 os we are getting the following errors:
SAP_U16_PROTOTYPE_STDC(mkstemp)..1 PCC-S-02201, Encountered the symbol "mkstemp" when expecting one of the following: Error at line 1895, column 1 in file /home/psoni/rfcsdk-710/orgseclib/sapuc.h SAP_U16_PROTOTYPE_UO(dirname) 1

e of the following: ; , = ( [ * ? | & < > + - / % . ^ *= /= %= += -= <<= >>= &&=
   ||= ^= | & == != <= >= << >> ++ -- ->
The symbol ";" was substituted for "SAP_U16_PROTOTYPE_UO_HLP" to continue.
Syntax error at line 1901, column 1, file /home/psoni/rfcsdk-710/orgseclib/sapuc.h:

:   ; , = ( [ * ? | & < > + - / % . ^ *= /= %= += -= <<= >>= &&=
   ||= ^= | & == != <= >= << >> ++ -- ->
I had checked the files sapuc.h and sapucx.h are correctly included in my program.
Also I checked for the errors : that the reference of some constants like
SAP_U16_PROTOTYPE is present is sapuc.h - However I am not able to
identify the cause of compilation issues.
Please can anyone guide me - or give any hints as to how this compilation issues can be resolved.
On sap rfc sdk version 6.20 with HPUnix 11iV1 we did not face such problems. Post that release we have tried all libraries including 6.40 and all of them are giving the above errors.
Thanks for the help.

Shivani

This compiler error looks really strange.
Without your sources (of the affected file) and the full command line it's impossible to suggest something.

============
It is showing this error and the idoc is not posting to the SAP. When i checked out the IDX2 i am not getting any such structure of our IDOC type, So do i need to create the structure manually, or will it create automaticallywhen the idocs willposted .
Is there any import and export option for this.
Please treat this as urgent , thanks in advance...

Hi Jay,
how did you create port using IDX1 ,I think you must have to follow the naming convention there.Any user given name might not work.
I think in your case , create port as SAPRP1 using IDX1.
can you you give a try with that.port name exactly same as SAPRP1.
you may also refer this link

RFC SDK download

I'm a newbie and purchased ABAP Objects book that has mini-basis system. Is there a way for me to get a copy of the RFC SDK so I can interface programs to my mini-basis system without having purchased a real system? I know there is a service marketplace but registering requires a customer number. 'Initial' is the customer number for a mini-basis system but the site won't accept that.

Hello,
you can get it via the SAP Service Marketplace (SMP). Please have a look at these links:

RFC SDK - timeout for RFC execution

Hi!
I was wondering if there was a way, when using the RFC SDK in client mode, to prevent a RFC call from taking more than a specified time to execute on the server.
Can I use the API RfcCallReceiveTimed?
Thanks,
Mustansir

Crash in SAP NetWeaver RFC SDK DLL

Hello community,
I have a problem with the SAP NetWeaver RFC SDK. Once in a while I get a crash with such error message:
Unhandled exception at 0x000007FEF1D3DD6E (sapnwrfc.dll) in bridgeserver.exe.22108.dmp: 0xC0000005: Access violation reading location 0x0000000000000008.
Basically I get function metadata, set the call parameters using the API calls and call RfcInvoke. It crashes. The callstack is:
sapnwrfc.dll!000007fef1d3dd6e()
sapnwrfc.dll!000007fef1d56613()
msvcr80.dll!_CallSettingFrame ()
msvcr80.dll!__CxxCallCatchBlock ()
ntdll.dll!RcConsolidateFrames ()
sapnwrfc.dll!000007fef1d5653a()
sapnwrfc.dll!000007fef1d2c4f7()
call RfcInvoke from my code
I've got the call stack from one of the two crash dumps I've got. I took a look on the registers and assembly of the top frame and it looks like an indirect acces to a field of a structure but the pointer to structure is NULL.
Is there any way I can debug it further? I'm already pretty sure that the parameters to RfcInvoke are correct (no messed-up pointers).

Thanks Mike,
For example we want to executie Function Module and need to prepare/allocate TABLE parameter.
In doing so we need to invoke function RfcGetStructureDescHandle is described in doc.
However, we cannot find it anywhere in H files under SAP NW SDK 7.10 dir structure.
Do you have an example of how to create a TABLE parameter (export for example).
We are going to reproduce the symptom with the demo source distributed with the SDK.
Any help/suggestions is greatly appreciated,
Alfonso

SAP NW RFC SDK throws RFC_INVALID_PARAMETER when running sample programs?

Hi there,
I have just downloaded the latest version of the SAP NW RFC SDK (NWRFC_7-20004565.SAR) for Linux 64 bit from the Service Marketplace and am trying to run the demo programs.
NOTE: I removed the "sapnwrfc.ini" from the current directory so that it would not be used at all..
Also note that I can use the OLD RFC SDK and connect happily to the same SAP system I am trying to connect to below using the SAP NW RFC SDK....so I definetly have the cirrect settings.....
So I compiled a CLIENT test program like:
gcc -m64 -Wall -g ./sflightClient.c -I/home/lynton/Desktop/nwrfcsdk/include -L/home/lynton/Desktop/nwrfcsdk/lib -lsapnwrfc -lsapucum -o ./sflightClient
And then passed in VALID paramters to an SAP system I have access to and I keep getting RFC_INVALID_PARAMETER even though I have not touched the code below in the sflightClient.c program
     loginParams[0].name = cU("ashost");     loginParams[0].value = argc > 1 ? argv[1] : cU("hostname");
     loginParams[1].name = cU("sysnr");     loginParams[1].value = argc > 2 ? argv[2] : cU("50");
     loginParams[2].name = cU("user");     loginParams[2].value = argc > 3 ? argv[3] : cU("user");
     loginParams[3].name = cU("passwd");     loginParams[3].value = argc > 4 ? argv[4] : cU("******");
     loginParams[4].name = cU("client");     loginParams[4].value = argc > 5 ? argv[5] : cU("800");
     loginParams[5].name = cU("lang");     loginParams[5].value = cU("EN");
I have also tried the stfcDeepTableServer.c program....and there I put in VALID settings....(and made the parameters UPPERCASE just like the settings in the "sapnwrfc.ini" file....
serverCon[0].name = cU("PROGRAM_ID");     serverCon[0].value = cU("TEST_SERVER");
        serverCon[1].name = cU("GWHOST");     serverCon[1].value = cU("test.server");
     serverCon[2].name = cU("GWSERV");     serverCon[2].value = cU("sapgw00");
     repoCon[0].name = cU("CLIENT");     repoCon[0].value = cU("000");
     repoCon[1].name = cU("USER");          repoCon[1].value = cU("BCUSER");
     repoCon[2].name = cU("PASSWD");     repoCon[2].value = cU("minisap");
     repoCon[3].name = cU("LANG");          repoCon[3].value = cU("EN");
     repoCon[4].name = cU("ASHOST");     repoCon[4].value = cU("test.server");
     repoCon[5].name = cU("SYSNR");     repoCon[5].value = cU("00");
        repoCon[6].name = cU("TRACE");     repoCon[6].value = cU("3");
I have the UUIDD daemon running perfectly on my box, but yet I keep getting this RFC_INVALID_PARAMETER regardless if I just test the SERVER REGISTRATION or a simple client connection.
I am connecting to a NON unicode system but that would not make a difference.....
Any idea what would cause this? Any help would be greatly appreciated ....
Thanks
Lynton

I have similar problem. My simply program use 7.10_x64_nwrfcsdk for Linux x64 and 7.10_IA32_nwrfcsdk for 32bit Linux. I has been prepared subroutine to convert ASCII to UTF16LE and control 2-byte Unicode length.
Program is working perfectly on x64 environment but didn't work on 32bit. I prepared log for it. In log converted to UTF16LE data are present as hex

Because ASCII conversion to UTF16LE (http://en.wikipedia.org/wiki/UTF-16) is very simple, I prepared function
char* ascii2utf16le( char *text_ascii)
    int rec=-1;
    int i=0;
    int j=0;
    int n=0;
size_t inbufsize = strlen(text_ascii);
size_t outbufsize=(2*inbufsize);
   i=2*inbufsize;
char *converted = calloc(outbufsize, sizeof(char));
    for(j=0;j<i;j++)
        if(0==(j%2))
            converted[j]=text_ascii[n];
            n++;
        } else {
          converted[j]=0;
        printf("%X ",converted[j]);
printf("\n");
    char *converted_str = converted;
    return converted_str;
and next I use it to loginParams[0].name = ascii2utf16le("ashost"), etc.
Fixed-length Unicode representation expected by SAP R/3 is under control, but on Linux 32bit not work.
I haven't where is possible problem?

Get data with rfc-sdk language c

Good morning all,
Me was given a task to develop a simple data read between C and SAP. To foreshadow my prerequisites: I did not work with SAP and only have the possibilities of the NW7.01 Trial with a MaxDB database.
I will use the RFC_READ_TABLE and the RfcCallReceive function. The error handling and opening the rfchandle runs.
Using the RFC_READ_TABLE requires to fill the export parameters and handle the 3 tables, FIELDS, OPTIONS and DATA.
Handling the tables throws the error:
RFC Call/Exception: SYSTEM_FAILURE
Group       Error group 104
Key         RFC_ERROR_SYSTEM_FAILURE
Message     Incorrect field length for 'Remote Function Call'.
After searching here this problem I place 3 structs to define the maximum length, which is returnd by the rfc:
typedef struct tDATA
{     SAP_CHAR     WA[512];
}tDATA;
typedef struct tFIELDS
{     SAP_CHAR     Fieldname[30];
     SAP_CHAR     Offset[6];
     SAP_CHAR     Length[6];
     SAP_CHAR     Type;
     SAP_CHAR     Fiedltext[60];
}tFIELDS;
typedef struct tOPTIONS
{     SAP_CHAR     WA[72];
}tOPTIONS;
Now using the size of these structs the error still stays the same.
So how do I initialise the tables and export parameters, to receive a useable data returned in the DATA table?
The declaration of the export and table structs is left out for now, I will post them immediatly if necessary.
Thanks & Regards
H.Fischer

Hi all,
I returned to my mind that there was a function embedded in the SDK which generates a headerfile which could be implemented easily. Now I have the structs necessary for the tables but the problem is still the same. I tried some configurations on the termination of the parameter list and I observe that the rfc does not handle with 5 export parameter tables. Here is the parameter declaration I try to use.
At last the tables are terminated with NULL, here I placed it at index 5 but with this the RFC throws an error about the RFC length mentioned in the first post. If I terminate at index 3 the "rfccallreceive" runs without error but returns two empty tables.
Or is it a problem in the declaration of ROWSKIPS and ROWCOUNT?
exporting[0].name = cU("QUERY_TABLE");
exporting[0].nlen = strlen(cU("QUERY_TABLE"));
exporting[0].addr = cU("SPFLI");
exporting[0].leng = strlen(cU("SPFLI"));
exporting[0].type = RFCTYPE_CHAR;
exporting[1].name = cU("DELIMITER");
exporting[1].nlen = strlen(cU("DELIMITER"));
exporting[1].addr = cU(" ");
exporting[1].leng = strlen(cU(" "));
exporting[1].type = RFCTYPE_CHAR;
exporting[2].name = cU("NO_DATA");
exporting[2].nlen = strlen(cU("NO_DATA"));
exporting[2].addr = cU(" ");
exporting[2].leng = strlen(cU(" "));
exporting[2].type = RFCTYPE_CHAR;
exporting[3].name = cU("ROWSKIPS");
exporting[3].nlen = strlen(cU("ROWSKIPS"));
exporting[3].addr = cU("0");
exporting[3].leng = strlen(cU("0"));
exporting[3].type = RFCTYPE_CHAR;
exporting[4].name = cU("ROWCOUNT");
exporting[4].nlen = strlen(cU("ROWCOUNT"));
exporting[4].addr = cU("0");
exporting[4].leng = strlen(cU("0"));
exporting[4].type = RFCTYPE_CHAR;
exporting[5].name = NULL; /*position I mean*/
importing[0].name = NULL;
tables[3].name = NULL;

RFC call failed : Error when opening an RFC connection

Hi,
As a result of "Start Data Collection" operation in the t-code RZ70, I have got this error.
"RFC call failed : Error when opening an RFC connection"
Others things are with success message.
