Undefined symbol: .DSOpenProjectEx

[rajan.n]

Hi All

I have a reqirement to use the DS functions in a c program, when i compile that i get the erors like
"
ld: 0711-317 ERROR: Undefined symbol: .DSOpenProjectEx
ld: 0711-317 ERROR: Undefined symbol: .DSOpenJob
ld: 0711-317 ERROR: Undefined symbol: .DSGetJobInfo
ld: 0711-317 ERROR: Undefined symbol: .DSCloseJob
ld: 0711-317 ERROR: Undefined symbol: .DSCloseProject
ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more information.
"

the code is below.

Code: Select all

#include <stdio.h>
#include <string.h>
#include<string.h>
#include</etl/Ascential/DataStage/DSEngine/include/dsapi.h>


int main()
{
DSPROJECT hProject;
DSJOB hJob;
int status;
char *project;
char *job;
DSJOBINFO jobInfo;
FILE *fp;
project = "ABC";
job = "job1";
int index;



hProject = DSOpenProject(project);
hJob = DSOpenJob(hProject,job);
status = DSGetJobInfo(hJob, DSJ_JOBSTARTTIMESTAMP, &jobInfo);
fp = fopen("Job.txt","w");
for ( index = 1 ; index <= 10; index++)
    fprintf(fp, "%s line number %d\n",ctime(&(jobInfo.info.jobStartTime)), status); 
fclose(fp);
(void) DSCloseJob(hJob);
(void) DSCloseProject(hProject);
return status;
}

can anybody help me in this issue , how to solve this.. need to use DS functions.
Thanks much in advance.

Instead of including the entire path of dsapi.h, try including just dsapi.h

Instead of including the entire path of dsapi.h, try including just dsapi.h

That says "can not find dsapi.h", have given the path of dsapi.h file.
the dsapi.h is working fine- this i can know by folowing
if i do include<dsapi.h> or remove that include
i get teh folowing errors...
DSPROJECT,DSJOB,DSJOBINFO...... these are the initialised in begin. so the error wil be same as undefined DSPROJECT .....and so on...
along with my prev errors..( like unknown DSOpenProject)

if i do include<..........path../dsapi.h> the above errors are not given and only the prev erors are thrown ( like unknown DSOpenProject)

can any one help me in this who has already used the DS functions in C language.

thanks ,
Rajan

Is the project set up in PX so that transforms will compile and run? If yes, it would seem that the include file should import the definitions - can you try to add -bloadmap or -bnoquiet to the compile for additional information on why the DllImport didn't work as expected.

Hi ArndW.
Thanks for the reply,
can u please specify where to include this -bloadmap ?
i use
> /usr/vacpp/bin/xlC_r job1.c
this is my command.

thanks,
Rajan.

Hi ArndW,
the command for -bloadmap is
>/usr/vacpp/bin/xlC_r -b loadmap:a.txt job.c
the a.txt file has the following :

This looks like UNIX and not Windows - which platform are you on? Also, have you compiled and run PX jobs that use transform stages on this machine (this is to ensure that you have the correct compiler installed with all necessary paths set up correctly)?

[rajan.n]

Hi ArndW,
i have run px jobs , but am sorry to ask abt transform stages, is this transformer stage..? if so we are using in many jobs.sorry if am wrong.

yes am runing this script on AIX , on server.
i aslo made a make file for creating the .o ans .so files for my c prog job.c,
sucessfuly , that makes .o and .so .but when i tried to use that in job as a paralell routine there i get the error belong to same unknown DSOpenProjeect...and remaining too....
"rtld: 0712-001 Symbol DSOpenProjectEx was referenced
from module /etl/Ascential/DataStage/Projects/CFM/RT_BP1031.O/V0S65_testds_T1.o(), but a runtime definition not found"
like this for all the remaining .

thnx for ur reply.

Hi,
Any updates on this post. I am also facing the same issue. When I compile the c++ program it is throwing the error "ld: 0711-317 ERROR: Undefined symbol: .DSOpenProjectEx"

As this thraed is 3 years old and most likely there are different versions and libraries involved, it would be best to open a new thread on the topic and to include additional information in the post.
