GCC Linking

1. LD is looking for linking name when doing linking in the compilation process

libmagic.so

2. Soname created by ldconfig 

ldconfig will create a soname as symbolic link

3. d-linux.so (dynamic loader) is looking for sonames when doing dynamic linking.

d-linux.so will look in the content of the cache file /etc/ld.so.cache when no sonames metioned above was found

(cache file /etc/ld.so.cache, which contains a compiled list of candidate libraries)

4. Create a symbolic link 

ln -s /webroot/home/httpd/test.com/index.php /home/vivek/index.php

5. run-time : exe + soname (.so.1)

compile-time : main.cpp + linkname (.so)

Note: both soname and linkname must be finally (maybe through linkname -> soname pipe) symbolic linking to realname

6. ld - The GNU linker (Compiler-time linker)

v.s.

        ld.so, ld-linux.so* - dynamic linker/loader    (Run-time linker)
