I am linking a program against libcrypto which is part of openssl. The package
is installed and living in /usr/lib:
lrwxrwxrwx 1 root root 14 2005-09-15 14:22 /usr/lib/libcrypto.so ->
libcrypto.so.0
lrwxrwxrwx 1 root root 18 2005-07-20 13:48 /usr/lib/libcrypto.so.0 ->
libcrypto.so.0.9.7
-rwxr-xr-x 1 root root 1358788 2004-08-04 12:09 /usr/lib/libcrypto.so.0.9.7
Note, the use of symbolic links as a good package should.
I link the app using -lcrypto (or even `pkg-config --libs opennsl` to get the
recommended settings: -lssl -lcrypto -ldl) and the app appears to link okay.
However, if I issue 'ldd <app>' it reports the following:
libcrypto.so.0.9.7 => /usr/lib/libcrypto.so.0.9.7 (0x4001f000)
libxml2.so.2 => /usr/lib/libxml2.so.2 (0x4014a000)
libpthread.so.0 => /lib/tls/libpthread.so.0 (0x4025e000)
libz.so.1 => /lib/libz.so.1 (0x40271000)
libm.so.6 => /lib/tls/libm.so.6 (0x40284000)
libc.so.6 => /lib/tls/libc.so.6 (0x402f4000)
libdl.so.2 => /lib/libdl.so.2 (0x4041d000)
/lib/ld.so.1 => /lib/ld.so.1 (0x40000000)
Not for all other libraries it uses the "generic" name rather than the specific
version. However, this is not the case for the libcrypto library. Why is this
so?
