Is it possible to use the src files without compiling them to a library ?

[ftv.dev]

I am trying to use Jansson C in a PowerPc machine but the problem that
I didn't succeded to compile it.

Is it possible to add just all the file in folder "jansson/src" to my
project and then compile the whole project ?

[Petri Lehtinen]

Yes it is, but you need to rename jansson_config.h.in to
jansson_config.h and edit for your target system.

It should also be possible (and relatively easy) to cross-compile
Jansson using the cross toolchain provided by ELDK. This is usually
very straightforward in cross building environments. You should check
the documentation of ELDK on how to do it.

I tried to do that (usin directly source files)
But i am getting a lot of errors:

This when using -Werror:

You're passing the -Wcast-qual option to gcc, and that's why you see
these warnings. They are harmless, but quite unavoidable.

You'll need to compile value.c and use value.o in the linking stage.

Thank you Petri for your response.
Yes I have discovered, yesterday that I forgot to compile the value.c.
Now every thing works great.
