Hi guys, i need some help
I am trying to use a C client generated by openapi-generator, and there is not any place where i found clearly what i need to use it.
I think i need to compile the library and then link this library to the code where i need to use it
Can someone help me with this?
Thanks

As discussed, the C Petstore integration test is a good reference: https://github.com/OpenAPITools/openapi-generator/blob/master/samples/client/petstore/c/unit-tests/manual-PetAPI.c

And the installation procedure can be found in the auto-generated README

@wing328 The installation procedure is not really clear, you explain how to use it, but if you want to compile it, and use C as a external link, you don't say nothing
In petstore case, i compile successfully the library, i guest the generator isn't work propertly for some instance, pls check that

@stdevMac can you please share the command to compile the library?

I totally agree with you that the documentation can be further improved.

I think this line is generic for any project so, maybe you can include it in your README.md for everyone that need it

$ gcc $(find . -name '*.c')  -I ./model -I ./include -I ./external/include -o some_output.out -lcurl

This step just work before install curl and incrustify

Do you mind filing a PR to update the readme mustache file so that the credit goes back to you?

[zhemant]

@stdevMac if you okay with using cmake, I will add a cmake file for petstore example which will make handling more easier. And I will update instructions about same in Readme.
About object.c/h I will be adding templates of those in some time. I have those templates almost ready.

[stdevMac]

pls @zhemant let me know when templates were ready, thanks
