The OpenSSL shared libraries are often installed in a directory like
|
|
/usr/local/ssl/lib.
|
|
|
|
If this directory is not in a standard system path for dynamic/shared
|
|
libraries, then you will have problems linking and executing
|
|
applications that use OpenSSL libraries UNLESS:
|
|
|
|
* you link with static (archive) libraries. If you are truly
|
|
paranoid about security, you should use static libraries.
|
|
* you use the GNU libtool code during linking
|
|
(http://www.gnu.org/software/libtool/libtool.html)
|
|
* you use pkg-config during linking (this requires that
|
|
PKG_CONFIG_PATH includes the path to the OpenSSL shared
|
|
library directory), and make use of -R or -rpath.
|
|
(http://www.freedesktop.org/software/pkgconfig/)
|
|
* you specify the system-wide link path via a command such
|
|
as crle(1) on Solaris systems.
|
|
* you add the OpenSSL shared library directory to /etc/ld.so.conf
|
|
and run ldconfig(8) on Linux systems.
|
|
* you define the LD_LIBRARY_PATH, LIBPATH, SHLIB_PATH (HP),
|
|
DYLD_LIBRARY_PATH (MacOS X) or PATH (Cygwin and DJGPP)
|
|
environment variable and add the OpenSSL shared library
|
|
directory to it.
|
|
|
|
One common tool to check the dynamic dependencies of an executable
|
|
or dynamic library is ldd(1) on most UNIX systems.
|
|
|
|
See any operating system documentation and manpages about shared
|
|
libraries for your version of UNIX. The following manpages may be
|
|
helpful: ld(1), ld.so(1), ld.so.1(1) [Solaris], dld.sl(1) [HP],
|
|
ldd(1), crle(1) [Solaris], pldd(1) [Solaris], ldconfig(8) [Linux],
|
|
chatr(1) [HP].
