[Zoo-discuss] Programming Language (Python) set in ZCFG file is not currently supported by ZOO Kernel.

[Fenoy Gerald]

Dear niroshan,
thanks a lot for this report.

You are perfectly right mentioning that it is required to run make clean in case you have already built the ZOO-Kernel without this support. I suppose that it comes from a wrong definition of the zoo_service_loader.o target on line 93 in the Makefile.in adding the following after service.h should solve this issue.

${MS_FILE} ${PYTHON_FILE} ${PHP_FILE} ${JAVA_FILE} ${JS_FILE} ${PERL_FILE} ${RUBY_FILE} ${YAML_FILE} ${OTB_FILE} ${SAGA_FILE} 

To make sure this solve the issue, you should try the following:

 1) add ${MS_FILE} ${PYTHON_FILE} ${PHP_FILE} ${JAVA_FILE} ${JS_FILE} ${PERL_FILE} ${RUBY_FILE} ${YAML_FILE} ${OTB_FILE} ${SAGA_FILE} to line 93,
 2) run configure script with python support deactivated,
 3) run make and verify that there is no more dependencies with python library (by using ldd command as you mentioned earlier),
 4) then run the configure script a second time with python support activated,
 5) run make again and make the same test to verify the link with the python library.

In case it works, then we will have to update the Makefile.in.

I hope to hear back from you tests and I hope we can solve this issue.

Best regards,

It does not return any values mean there is no connection in between python  library and ZOO-kernel. Now let's run the make clean and check the connection. For that you can run  "make clean" command, then you can run "make" and check with the "ldd zoo_loader.cgi | grep python"  command (you can run them together with "make clean && make && ldd zoo_loader.cgi | grep python" command). Now it has return something. In my case it has return the following result:
