Using zproject class generator without using czmq

[domiq44]

Hello,

I'm just trying to use a small part of zproject, a part on class generation, for fun.

<project
	name = "Test DOMDOM"
	script = "zproject.gsl"
	prefix = "pipo" >
	<main name = "totor">Global Domination Demon</main>
	<class name = "dudu" />
</project>

So for this test, you can create a new directory with only project.xml and zproject_class.gsl, and run
$ gsl project.xml

Since I'm interested in class generation without czmq, I create a project removing the following line in project.xml
<use project = "czmq" />
It's a cool feature for people who don't want to use czmq.
So, I run all process with
$ ./autogen.sh && ./configure && make
The make failed with the following error :

src/totor.c:40:9: warning: implicit declaration of function ‘zsys_info’ [-Wimplicit-function-declaration]
   40 |         zsys_info ("totor - Global Domination Demon");
      |         ^~~~~~~~~

A turn arround can me made by modifying the generator zproject_class.gsl like this:

$ diff zproject_class.gsl.ORIGINAL zproject_class.gsl
560a561,565
> 
> #define zsys_info(x, args ...)    fprintf(stdout, "\\n" x, ## args)
> #define zsys_warning(x, args ...) fprintf(stdout, "\\n" x, ## args)
> #define zsys_debug(x, args ...)   fprintf(stdout, "\\n" x, ## args)
> 

But I know that these are functions, not just define. It's just for tests purpose.
Then, doing ./autogen.sh && ./configure && make again will be OK and running test too.

$ ./src/pipo_selftest 
Running test domdom selftests...
 * dudu: OK
Tests passed OK

Regard,
Dominique
