If "make install" does not work correctly, it should be patched
in 3.2.x I believe.  But I haven't followed the discussion thoroughly
so feel to disregard this if it is out of context.




Jerry,

This is correct.  "make install" does not work and forgets to create
the
symbolic links to the libraries.  As a result, samba may not start
correctly and generate errors when loading.  Packagers have been able to
get around this; but, users installing from source will have a difficult
time or need to create the symbolic links themselves.
The effected files on my build are libnetapi.so.0, libtalloc.so.1,
libtdb.so.1 and libwbclient.so.0.  But this depends on the build as
there are other libraries that also need symbolic links added, if built.

Thanks,
James

Michael,

technically the correct thing to do is to install as libXX.so.1 and then
have the .so symlink point to the sonamed library.  This allows more
than one soname lib to exist at the same time (if necessary).  The .so
file is only used when linking.

For example:

	libtalloc.so.1
	libtalloc.so -> libtalloc.so.1

Not the other way around.  Do you agree?





cheers, jerry

Yes, though this would mean you would have to be sure the executables
linked to libtalloc.so and not necessarily to libtalloc.so.1 like it
seems to now.
Some have even added a step further by providing a structure like this:
	libxyz.so.1.2.3
	libxyz.so.1 -> libxyz.so.1.2.3
	libxyz.so -> libxyz.so.1.2.3
So I guess it really depends on how deep we want to take this.

I think I understand.
  1)  Redhat and maybe others like putting samba libraries in another 
directory.  So, they use this link to point the libtalloc.so.1 to the file 
in the correct directory.  This is really NOT the proper way... what happens 
then is the library gets referenced by the libtalloc.so.1 which links to the 
libtalloc.so file in the /usr/lib/samba directory.  This may lead to 
inefficiant library loading; but, it does work.
  2)  A better way would be to:
    a)  straigten out the symbolic links.  The symbolioc link libtalloc.so 
should point to libtalloc.so.1 the file.
    b)  add /usr/lib/samba to the /etc/ld.so.conf file where it should be --  
or -- put the libraries in the /usr/lib directory.
    c)  fix the Makefile to properly create the libraries the way they 
should be; instead of back-linking.  It is just a term I coined for this 
werid configuration.

This should fix things.  I'll try to create a patch for this in my spare 
time.  The install section will also need to install the symbolic links to 
the files in their proper locations; weather it be in /usr/lib/samba or 
other.

Hi Michael,

I did a ./configure... then a make all and got this:

Hi James,

attached find combined diff of my changes.
That should work agains the vanilla 3.2.1 tarball.
This is what is going to be released next week in 3.2.2.

This is the whole thing from 3-3-test.
It took me some time and effort to port it back to 3-2-test. :-)

I will of course greatly appreciate any feeback!

Thanks - Michael

Well, more likly my patch was not correct:
I produced it from the v3-2-test branch.
I may have forgotten an intermediate commit.

Did you apply the patch to the 3.2.0 sources?
The patch does not apply cleanly to these.
You should use the 3.2.1 sources (available from http://www.samba.org/).

If that does not help, I need to try and get the patch
complete for 3.2.1.

But you can simply try the v3-2-test branch, if you like:
Either check out the git repository, as detailed in
http://wiki.samba.org/index.php/Using_Git_for_Samba_Development
or alternatively, you can download snapshot tarballs
from the mirror at
http://repo.or.cz/w/Samba.git?a=shortlog;h=refs/heads/v3-2-test
Here is a direct link to the current head of the branch:
http://repo.or.cz/w/Samba.git?a=snapshot;h=41d440c3198752281556699cc9744b490b9b0a5e;sf=tgz

I will also check to get the proper patch on top of 3.2.1.

Cheers - Michael

Here is an updated patch for 3.2.1.
This one should work. I had forgotten the diff portion of m4/aclocal.m4.
Sorry for that!

Hi Michael,

Everything compiled, and installed with the proper links.  I'm getting ready
to test a RPM build to see if this works.  Will let everyone know in about 1-2
hours.
