Re: A general question about libnss3

Ubuntu has apparently chosen to use non-standard library names, therefore you can't use your binary produced on Ubuntu on a system that uses standard library names.

Recompile.

Hi,

It gives the version as NSS 3.12.0.2.

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

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

and then the messages like
: undefined reference to [EMAIL PROTECTED]'
: undefined reference to [EMAIL PROTECTED]'
: undefined reference to [EMAIL PROTECTED]'
: undefined reference to `PR_Initialized'
: undefined reference to [EMAIL PROTECTED]'

Thanks

Hi,



I see libnss3-0d

          libnss3-1d

          libnss3-1d-dbg

          libnss3-dev

etc.


I have the following in my /usr/lib





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



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







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





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











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

Can anybody tell me something about the various nss packages that are there in ubuntu (hardy). 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 lrwxrwxrwx 1 root root 23 2008-07-07 16:00 libnss_compat.so -> /lib/libnss_compat.so.2 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 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 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.

I don't understand why Ubuntu uses versioning of the .so files, it
should not be necessary.
The newest NSS libs should work fine with software that expects the
older versions, because of NSS' promise that it should always be
possible to replace old binaries with newer NSS binaries.

Try to grep the .so files for string NSS, it should reveal the version
number strings.

strings libnss3.so | grep -w NSS
