How to link libxml when compiling?

[geoplab]

I have this error message when compiling mx_init.c by linking libxml
library as follow:

gcc `xml2-config --cflags` -c mx_init.c `xml2-config --libs` -g -Wall
gcc: -lxml2: linker input file unused because linking not done
gcc: -lz: linker input file unused because linking not done
gcc: -lpthread: linker input file unused because linking not done
gcc: -lm: linker input file unused because linking not done

How can I fix this error?
Thank you in advance.

gcc and libraries are not really on topic in comp.lang.c, which
deals with the C language rather than with the specifics of
any implementation.

<OT>
Read the output. The libraries were not used because linking
was not done. Why was linking not done? Because you told it not
to link.

$ man gcc
-c Compile or assemble the source files, but do not link. The link-
ing stage simply is not done.

This is compiler-specific, so really doesn't belong in comp.lang.c. A
gcc newsgroup or mailing list might have been a better choice. An even
better choice is to check your documentation, where you would find that
the "-c" flag tells the compiler not to link or produce an executable.
Since it refuses to do what you told it not to do, there is no error.
Here's a hint: when an application does what you tell it to, and you
don't like the result, then you probably told it the wrong thing to do.

Thank you in advance.

Bite me.

The -c parameter says to compile to object file only, do not link.
