The C compiler does not know what to call your final executable, so it has defaulted the name to a.out.

It is unusual for the compiler to place the output in the /usr/bin directory, usually it is placed into your current directory.

Nearly all compiliers, including those on Unix and Linux will accept a number of command line switches and parameters. By using command line parameters you can change the behaviour of the compiler significantly. See for yourself by doing:

man cc

or

man gcc

This will give you a very lengthy description of what to expect from your compiler. Also read the man page on your linker.

man ld

Somewhere in that lot will be a way to change the output file name. If necessary you can give it an explicit path name.


Finally, if you did not realise it already, the a.out file is (or should be) a fully runnable executable. You can always rename it using the move or copy command!

Regards

MBB.

xml2-config

xml2-config(1)						      General Commands Manual						    xml2-config(1)

NAME

       xml2-config - script to get information about the installed version of libxml

SYNOPSIS

       xml2-config [--prefix[=DIR]] [--libs] [--cflags] [--version] [--help]

DESCRIPTION

       xml2-config  is	a  tool  that  is used to determine the compile and linker flags that should be used to compile and link programs that use
       libxml.

OPTIONS

       xml2-config accepts the following options:

       --version
	       Print the currently installed version of libxml on the standard output.

       --libs  Print the linker flags that are necessary to link a libxml program.

       --cflags
	       Print the compiler flags that are necessary to compile a libxml program.

       --prefix=PREFIX
	       If specified, use PREFIX instead of the installation prefix that libxml was built with when computing the output for  the  --cflags
	       and --libs options. This option must be specified before any --libs or --cflags options.

AUTHOR

       This manual page was written by Fredrik Hallenberg <hallon@lysator.liu.se>, for the Debian GNU/linux system (but may be used by others).

NOTES

       Source for libxml is available in the SUNWlxmlS package.  Documentation for libxml is available on-line at http://www.xmlsoft.org/
