Actually, I was advised to put libssl after libcrypto. I don't recall being
told to put libssl after libldap. Also, knowing that order matters is of
little use if you don't grasp what the order should be.
I did show the link command in a previous post, but admittedly not up to date
with this particular set of errors. I'll remember to include my link command
with every example of error messages.
I have achived partial success today by including some static libraries in the
link command along with my own object files, rather than linking them in as
libraries, but I am far from being able to use the -static flag. In several
experiments I tried in the afternoon, I could get the thing to the point where
all the errors were comin from ldap, but there were many.
I will try to be more informative in future posts. The advice I have received
here so far has taught me a lot.

Subject: RE: Trying to Link Statically to Libcrypto
The output is little or no help in knowing specifically what you've done wrong,
What link command line did you use?
The most likely explanation of this is that you still haven't done what several
different people here have advised you several times, including in the messages
quoted below - made sure that the reference to the OpenSSL libraries comes
_AFTER_ the references to the ldap library in the link command. As everyone
keeps saying, _order_matters_.
I don't recognise the names of some of the missing references below; they may
be OpenSSL references I'm not aware of, or they may be to some other library
which the ldap library needs. If its the latter, you'll need to look at the
documentation of the ldap library to see what it needs, and include it on the
link command line. Since _order_matters_, you'll need to include it _after_ the
reference to the ldap library.

Subject: Re: Trying to Link Statically to Libcrypto
Some incredibly helpful advice, which I appreciate very much. I'll apply it
all tomorrow morning. It makes a lot of
sense to find out that I've been putting the -static flag in the wrong place,
because I had to develop scripts to temporarily
hide shared libraries from the linker, whenever I made a version of my
executable to be used or tested elsewhere, to force
the linker to chose the static versions. I wondered why the -static flag
wasn't working. In my present job, I only have time
to research new things briefly, and not at length as I would prefer.

y program, it complained that it couldn't find libcrypto.so.8. I fixed that on
hose occasions by creating a symbolic link to their actual version of
ibcrypto, but I just want it to stop looking for any library at all on the box
here I'm putting it, and this is one step towards that. I had hoped that by
orcing it to take libcrypto.a, rather than libcrypto.so, it would stop looking
or libcrypto.so.8.
When you pass -static to the linker as part of the link command,
t will search for libcrypto.a rather than the default (dynamic)
ibcrypto.so (which should be a sym-link to the current version
amed libcrypto.so.VERSION-NUMBER).
Also remember that the application: /usr/bin/g++ which you are
alling is just the "front end" of that toolchain.
t calls the sub-components (pre-processor, compiler, assembler,
inker, etc) as required based on the options and files it is passed.
Note also when you did:
++ --help
n a terminal window that the order is:
++ <options> files
ot:
++ files <options>
Also try:
nfo g++
n a terminal window.

e certainly meant -lldap (the library is called libldap.so, so
he linker flag is called -lldap). If your library really is
alled openldap.so (which I very much doubt), then you can not
ink it with the -l option, you have to add the fully qualified
ath name of that library to the linker command line.

Link to OpenSSL first, and then OpenLdap (order matters):
gcc ... -lcrypto -lopenldap
hat was meant is "-lldap -lcrypto". Libraries later in later
lags have to satisfy references left open by earlier libraries.

ou are linking statically to a library that some other library,

o work? Static linking means you have a copy of libcrypto in
our binary, with the symbols of that library removed, because
hey have already been resolved. Then libldap gets linked, and
ants to know about the same symbols once again, so a shared copy
f the library libcrypto has to be added to the address space.
hat a mess. So the real question is: WTH are you trying to link
tatically!
