Help while linking the library in AIX
Hi,
I have one library(libfoo.a) that is folder /home/xyz and my c program is in /home/xyz/cprog. Whenever I issue cc command
cc -o test test.c -lfoo , i get the error /usr/bin/ld: cannot find -lfoo.
echo $PATH has already listing of /home/xyz variable, even LIBPATH also has same entry /home/xyz.
Can some one tell me why compiler not able to locate the library.

whenever i issue the command

cc -o test test.c -L lfoo, it works and gives me the executable.

Please tell me , how does compiler able to locate the library file with -L option , I have not given any path of library.

dh_shlibdeps

DH_SHLIBDEPS(1) 						     Debhelper							   DH_SHLIBDEPS(1)

NAME

       dh_shlibdeps - calculate shared library dependencies

SYNOPSIS

       dh_shlibdeps [debhelperoptions] [-Lpackage] [-ldirectory] [-Xitem] [--params]

DESCRIPTION

       dh_shlibdeps is a debhelper program that is responsible for calculating shared library dependencies for packages.

       This program is merely a wrapper around dpkg-shlibdeps(1) that calls it once for each package listed in the control file, passing it a list
       of ELF executables and shared libraries it has found.

OPTIONS

       -Xitem, --exclude=item
	   Exclude files that contain item anywhere in their filename from being passed to dpkg-shlibdeps. This will make their dependencies be
	   ignored.  This may be useful in some situations, but use it with caution. This option may be used more than once to exclude more than
	   one thing.

       -- params
	   Pass params to dpkg-shlibdeps(1).

       -uparams, --dpkg-shlibdeps-params=params
	   This is another way to pass params to dpkg-shlibdeps(1).  It is deprecated; use -- instead.

       -ldirectory[:directory ...]
	   With recent versions of dpkg-shlibdeps, this option is generally not needed.

	   It tells dpkg-shlibdeps (via its -l parameter), to look for private package libraries in the specified directory (or directories --
	   separate with colons). With recent versions of dpkg-shlibdeps, this is mostly only useful for packages that build multiple flavors of
	   the same library, or other situations where the library is installed into a directory not on the regular library search path.

       -Lpackage, --libpackage=package
	   With recent versions of dpkg-shlibdeps, this option is generally not needed, unless your package builds multiple flavors of the same
	   library or is relying on debian/shlibs.local for an internal library.

	   It tells dpkg-shlibdeps (via its -S parameter) to look first in the package build directory for the specified package, when searching
	   for libraries, symbol files, and shlibs files.

	   If needed, this can be passed multiple times with different package names.

EXAMPLES

       Suppose that your source package produces libfoo1, libfoo-dev, and libfoo-bin binary packages. libfoo-bin links against libfoo1, and should
       depend on it. In your rules file, first run dh_makeshlibs, then dh_shlibdeps:

	       dh_makeshlibs
	       dh_shlibdeps

       This will have the effect of generating automatically a shlibs file for libfoo1, and using that file and the libfoo1 library in the
       debian/libfoo1/usr/lib directory to calculate shared library dependency information.

       If a libbar1 package is also produced, that is an alternate build of libfoo, and is installed into /usr/lib/bar/, you can make libfoo-bin
       depend on libbar1 as follows:

	       dh_shlibdeps -Llibbar1 -l/usr/lib/bar

SEE ALSO

       debhelper(7), dpkg-shlibdeps(1)

       This program is a part of debhelper.
