YumaWorks

Following the steps described in the online documentation for the YControl initialization and DB-API Service Registration, I am unable to get the DB-API Service ready via the function call, db_api_service_ready, within a test program I created.

Please see the attached files which document the test program, the program output, netconfd-pro configuration setup (bundle and module names removed), netconfd-pro server log (debug4), and strace output from the test program.

YumaPro SDK Basic installed is 21.10-5-1fcb and this is running on RHEL 8.6.

The code snippet I attached in DB-API-Init-Code-Snippet.txt is basically patterned after your main.c in /usr/share/yumapro/src/db-api-app directory.

There are a couple of items I see from the Makefile supplied in that directory that are missing in my installation of your SDK.  For one there is this refererence to a library, sendbuff, that I am been unable to locate in any Open Source or Linux Distribution:

LIBS = -lyumapro_db-api \

 -lyumapro_ycontrol -lsendbuff \

 -lyumapro_ncx -lxml2 -lz -lm

For the other, there are references to subsys-pro library objects for which I cannot locate within the YumaWorks SDK installation:

SUBSYS_TARGET=$(TBASE)/subsys-pro

LOBJS = $(SUBSYS_TARGET)/subsystem.o

LOBJS += $(SUBSYS_TARGET)/subsys_util.o

If I attempt to build the db-api-app using this Makefile, I get the following error:

...share/yumapro/src/db-api-app> sudo make all

Compiling in C++11 mode

make: *** No rule to make target 'procdefs.h', needed by '../../target/db-api-app/main.o'. Stop.

As I previously mentioned, I am able to compile and link my test application without these referenced library or library objects using the specified APIs from the main.c for db-api-app along with using the specified libraries from above.

It is obvious I am missing something in my development environment to pull in the necessary subsys-pro elements required for registering the DB-API service and to compile the test program for db-api-app.

I have tried running the db-api-app program installed in /usr/bin and I see from the netconfd-pro server.log the DB-API service is being registered from this application:

agt_ycontrol: Got <ycontrol> message:

yctl:ycontrol {

  message-type subsys-request

  server-id

  subsys-id subsys1

  service-id db-api

  payload {

    ydb:db-api {

      register-request

    }

  }

}

DB-API: enter service function

DB-API: enter subsys_request

Thanks.
