Regarding library names in Ubuntu

[Ruchi Lohani]

Hi,

 

This is regarding the library names that ubuntu keeps. 

I have installed the mozilla NSS libraries n my Ubuntu Hardy using
apt-get install

 

I see libnss3-0d

          libnss3-1d

          libnss3-1d-dbg

          libnss3-dev

etc.

 

I have the following in my /usr/lib

lrwxrwxrwx 1 root root      13 2008-07-17 16:47 libnss3.so ->
libnss3.so.1d

lrwxrwxrwx 1 root root      13 2008-07-17 16:47 libnss3.so.0d ->
libnss3.so.1d

-rw-r--r-- 1 root root 1156684 2008-05-29 02:52 libnss3.so.1d

lrwxrwxrwx 1 root root      23 2008-07-07 16:00 libnss_compat.so ->
/lib/libnss_compat.so.2

-rw-r--r-- 1 root root   18876 2008-01-18 03:44 libnss_db-2.2.3.so

lrwxrwxrwx 1 root root      14 2008-07-17 16:47 libnss_db.so ->
libnss_db.so.2

lrwxrwxrwx 1 root root      18 2008-07-17 16:47 libnss_db.so.2 ->
libnss_db-2.2.3.so

lrwxrwxrwx 1 root root      20 2008-07-07 16:00 libnss_dns.so ->
/lib/libnss_dns.so.2

-rw-r--r-- 1 root root    8452 2007-05-18 05:57 libnss_extrausers.so.2

lrwxrwxrwx 1 root root      22 2008-07-07 16:00 libnss_files.so ->
/lib/libnss_files.so.2

lrwxrwxrwx 1 root root      23 2008-07-07 16:00 libnss_hesiod.so ->
/lib/libnss_hesiod.so.2

-rw-r--r-- 1 root root   33652 2008-02-01 21:08 libnss_ldap.so.2

lrwxrwxrwx 1 root root      24 2008-07-07 16:00 libnss_nisplus.so ->
/lib/libnss_nisplus.so.2

lrwxrwxrwx 1 root root      20 2008-07-07 16:00 libnss_nis.so ->
/lib/libnss_nis.so.2

lrwxrwxrwx 1 root root      17 2008-07-17 16:47 libnssutil3.so ->
libnssutil3.so.1d

lrwxrwxrwx 1 root root      17 2008-07-17 16:47 libnssutil3.so.0d ->
libnssutil3.so.1d

 

Whereas my other Linux box which has Suse 10 on it has only libnss3.so,
libnspr4.so and all. 

 

What are libnss3.so.[0d,1d] etc? 

 

The problem I am facing is when I build my program on ubuntu linking to
nss and nspr it works fine on Ubuntu but when I try to use the same
library built on Ubuntu on Suse its unable to resolve the symbols and I
get the following messages When I do 'ld' on the library. 

 

ld: warning: libssl3.so.1d, needed by **** not found (try using -rpath
or -rpath-link)

ld: warning: libnss3.so.1d, needed by **** not found (try using -rpath
or -rpath-link)

ld: warning: libnspr4.so.0d, needed by **** not found (try using -rpath
or -rpath-link)

 

and then the messages like

: undefined reference to `NSS_InitReadWrite at NSS_3.2'

: undefined reference to `CERT_GetDefaultCertDB at NSS_3.2'

: undefined reference to `SSL_ForceHandshake at NSS_3.2'

: undefined reference to `PR_Initialized'

: undefined reference to `SSL_OptionSet at NSS_3.2'

 

 

Does this mean that I cant use the same binary on other Linux which were
built on ubuntu?

Why is Ubuntu using non-standard names for libraries?

 

 

 

Thanks
