1 | The OpenSSL shared libraries are often installed in a directory like |
2 | /usr/local/ssl/lib. | |
3 | ||
4 | If this directory is not in a standard system path for dynamic/shared | |
5 | libraries, then you will have problems linking and executing | |
6 | applications that use OpenSSL libraries UNLESS: | |
7 | ||
8 | * you link with static (archive) libraries. If you are truly | |
9 | paranoid about security, you should use static libraries. | |
10 | * you use the GNU libtool code during linking | |
11 | (http://www.gnu.org/software/libtool/libtool.html) | |
12 | * you use pkg-config during linking (this requires that | |
13 | PKG_CONFIG_PATH includes the path to the OpenSSL shared | |
14 | library directory), and make use of -R or -rpath. | |
15 | (http://www.freedesktop.org/software/pkgconfig/) | |
16 | * you specify the system-wide link path via a command such | |
17 | as crle(1) on Solaris systems. | |
18 | * you add the OpenSSL shared library directory to /etc/ld.so.conf | |
19 | and run ldconfig(8) on Linux systems. | |
20 | * you define the LD_LIBRARY_PATH, LIBPATH, SHLIB_PATH (HP), | |
21 | DYLD_LIBRARY_PATH (MacOS X) or PATH (Cygwin and DJGPP) | |
22 | environment variable and add the OpenSSL shared library | |
23 | directory to it. | |
24 | ||
25 | One common tool to check the dynamic dependencies of an executable | |
26 | or dynamic library is ldd(1) on most UNIX systems. | |
27 | ||
28 | See any operating system documentation and manpages about shared | |
29 | libraries for your version of UNIX. The following manpages may be | |
30 | helpful: ld(1), ld.so(1), ld.so.1(1) [Solaris], dld.sl(1) [HP], | |
31 | ldd(1), crle(1) [Solaris], pldd(1) [Solaris], ldconfig(8) [Linux], | |
32 | chatr(1) [HP]. |
