All,
I'm porting some code to z/OS that does LDAP API calls. I have the z/OS C header libraries 'LDAP.SGLDHDRC' and it compiles fine but I get linker errors about missing modules.
I've done a lot of searches and there is very little on the subject, but I did find the following IBM posting:
http://www-1.ibm.com/support/docview.wss?uid=isg1II13026
If you scroll down to section # 5, it sounds like a solution to my problem.
I added the PreLink DD and PreLink Sysin include statement. But it did not help. I checked the PreLinker's output and I can see my 'INCLUDE SYSLIB(GLDCLDPX)' statement and there are no PreLink errors. So, I am stumped.
I must have missed something obvious but I don't know what it could be.
Does anyone have sample JCL and Sysin member(s) for compiling and linking a simple client LDAP application for the mainframe?
Any help would be appreciated.
Regards,
Roger Lacroix

Hello Roger,
I don´t like to bring an older post back, but I am facing similar challenges. After compiling, prelinking and linking with success I still get ABEND=S0C1 U0000 REASON=00000001 when I try to run the module.
| Code: |
CEE3201S The system detected an operation exception (System Completion Code=0C1)
From entry point main at compile unit offset -16F00050 at entry offset
Possible Bad Branch: Statement: Offset: +00000080
|
The ugly part I cleared the code, now it is just a printf, there is no ldap specific code at all. After the linking with ldap objects I get a useless executable. If I strip the SYS1.SIEALNKE
(GLDCLDAP) mention on the JCL linker STEP (tried IEWL and HEWL), then the program runs perfect.
I think I am including correctly the side deck definitions (they rename a bunch of longname functions) from HLQ.SGLDEXPC(
GLDCLDPX) - I tried EUVCLDAP also - in the prelinker step.
I followed also the instructions on these IBM posts, putting using all #pragmas and #defines, but no sucess so far. Also I doubt they were going to change something, since they are compile time definitions.
The JCLs for this sort of compile are very bad documented on the IBM Information Center.
How did you deal with this issue?
Best Regards, |

Hi,
Is this for:
- Simple LDAP program (no MQ code) that makes client LDAP calls
- A program that uses MQ and client LDAP calls
- An MQ Exit that is attempting to make client LDAP calls

Hi,
Here is a bunch of JCL from my testing back in 2007.
Here is the compile JCL:
| Code: |
//ROGERC1 JOB (05,555,55555,55555),'CPL MYBIND',
// CLASS=A,MSGCLASS=H,MSGLEVEL=(1,1),
// USER=ROGER,NOTIFY=&SYSUID,
// REGION=0M,TIME=1440
//*
//PROC JCLLIB ORDER=(ROGER.TEST.PROCLIB)
//*
//STEP1 EXEC CCNC,CREGSIZ=0M
//*
//SYSIN DD DISP=SHR,DSN=ROGER.TEST.C(MYBIND)
//OPTIONS DD DISP=SHR,DSN=ROGER.TEST.C(CBCC1)
//SYSLIB DD DISP=SHR,DSN=WMQ.V6R0.SCSQC370
//*
//PLKED.SYSLIB DD
// DD DSN=LDAP.SGLDEXPC,DISP=SHR
//PLKED.SYSIN2 DD *
INCLUDE SYSLIB(GLDCLDPX)
/*
//PLKED.SYSMOD DD DISP=SHR,DSN=ROGER.TEST.OBJECT(MYBIND)
//* |
Here are the Options used:
| Code: |
SEARCH('SYS1.SCEEH.+',
'SYS1.SCEEH.SYS.+',
'SYS1.SIEAHDR.H',
'WMQ.V6R0.SCSQC370',
'SYS1.SAMPLIB',
'LDAP.SGLDHDRC',
'ROGER.TEST.H' )
SO NOSHOWINC EXP NOSTART LIST CSECT XREF |
Here is the CCNCL PROC:

//SYSLMOD DD DSN=&OUTFILE
//SYSUT1 DD UNIT=SYSDA,SPACE=(32000,(30,30))
//SYSPRINT DD SYSOUT=*
//SYSIN DD DUMMY
//* |
Note: The PLINK member is empty and the LINK member just has 'NAME MYBIND(R)'.
Here is the JCL to run MYBIND:
| Code: |
//ROGERR1 JOB (05,555,55555,55555),'RUN BIND',
// CLASS=A,MSGCLASS=H,MSGLEVEL=(1,1),
// USER=ROGER,NOTIFY=&SYSUID,
// REGION=56M,TIME=1440
//*
//H1 SET HOST='10.10.10.10'
//H2 SET HOSTPT='389'
//LGNDN SET LOGINDN='cn=Barney Rubble,ou=people,dc=capitalware,dc=net'
//PWD SET PASSWD='mypwd'
//*
//*
//RUN01 EXEC PGM=MYBIND,
// PARM='&HOST &HOSTPT &LOGINDN &PASSWD'
//STEPLIB DD DISP=SHR,DSN=ROGER.TEST.LOAD
// DD DISP=SHR,DSN=SYS1.SIEALNKE
//SYSPRINT DD SYSOUT=*
//*
// |
Hope that helps.

Helped a lot! 
In fact, IBM documentation made think on using SYS1.SIEALNKE(GLDCLDAP) on the link-editing, while it was only needed for runtime. This ended up corrupting the entry point of the executable.
Now I can focus on the logic. |
