JCL Error trying z/OS JSON parser programming example

Question

I tried copying the c++ example as mentioned here -

https://www.ibm.com/support/knowledgecenter/en/SSLTBW_2.3.0/com.ibm.zos.v2r3.ieac100/ieac1-cwe-json-prog.htm

However, I am getting the following JCL error when running on my system :

 IEF344I XC1CPLLE COMPILE SYSLIB - ALLOCATION FAILED DUE TO DATA FACILITY SYSTEM ERROR
 IGD17045I SPACE NOT SPECIFIED FOR ALLOCATION OF DATA SET
 SIEAHDR.H
 IEF272I XC1CPLLE COMPILE - STEP WAS NOT EXECUTED.

Here is a copy of my modified program :

Being a member for as long as you have, you should really know better than to post a "question" like this! Please re-read the help pages, especially "What topics can I ask about here?" and "What types of questions should I avoid asking?". Also re-take the tour and re-read about how to ask good questions. — Some programmer dude
Sorry - can you be more specific? Whats wrong with the question? I'd be happy to delete it or correct if I knew what was wrong with it. — surtyaar
I removed some information I believe was irrelevant. Is that acceptable now? — surtyaar
Please post your entire JCL stream. The compilation step is trying to create SIEAHDR.H, which makes no sense for a compiler. Did you possibly forget DISP in your //SYSLIB concatenation? Remember, DISP default is NEW, not SHR or OLD. — zarchasmpgmr
Yep thanks @zarchasmpgmr thats the answer. I originally posted the entire JCL stream but I was referenced to posting bad questions (see above) and my only guess was that my question had a lot of superfluous stuff in it. — surtyaar

The JCL to which you provide a link contains a JCL error. The SYSLIB DD of the COMPILE step has no DISP and thus defaults to DISP=(NEW,DELETE,DELETE). A status of NEW requires space allocation and none is provided, so you get the error in your question. To fix this particular problem, I suggest coding DISP=SHR on the SYSLIB DD in the COMPILE step.

I recommend talking to your support staff about standard compile procedures, as most shops implement their own.
