[Ftpapi] HTTPAPI - Binding step fails with CPDD02 - Definition not found for symbol 'HTTP_STRING'

I have downloaded HTTPAPI version 1.40 and compiled it following the excellent instructions.
Now I have tried to implement it in my program.


But when compiling it I’m getting an error during the binding step and I can’t find out what is wrong.

The program compiles without error but it is the binding step that fails with CPD5D02.



I have removed comments and anonymized the literals in it.

The library list contains LIBHTTP.







     D LOCAL           DS          2000




     D URL             s            256A

     D request         s            256A

     D response        s               A   len(100000)


     C     *ENTRY        PLIST

     C                   PARM                    LOCAL


       http_setAuth( HTTP_AUTH_BASIC: 'XXX': 'XXX');

       request = '';

       url = 'http://myServer:9999/xxxx.............';

       response = http_string('POST': url: request: 'application/json');


     C                   seton                                        LR

     C                   return



The error from the job log is as follows:

If I comment the code with http_string it will compile.

But I can’t figure out why it can find  http_setAuth  but not  http_string  ?


I have now checked the sources of HTTPAPI_H, HTTPAPIR4 and even INSTALL.

Nothing seems to be wrong.


The only thing I have found is that the service program HTTPAPIR4 has the creation date 16 april 2020.

But when doing a DSPBNDDIR BNDDIR(LIBHTTP/HTTPAPI) it shows me this:


Object       Type         Library      Activation   Date         Time     

EXPAT        *SRVPGM      *LIBL        *IMMED       31.05.18     10:10:25 

HTTPAPIR4    *SRVPGM      *LIBL        *IMMED       31.05.18     10:10:38 


The creation date is 31 may 2018.                                                                          

I would have expected the date to be 16 april instead.

The INSTALL program  deletes the binding directory HTTPAPI and rebuilds it again. So shouldn’t the creation date be updated?


So the big question is – what have I done wrong?
