Dynamic library lookup on HP-UX

[Martin Frydl]

I have problems with hardcoded paths to shared libraries on HP-UX. When 
libtool creates executable or shared library, it hardcodes paths to any 
dependency libraries into it and disable dynamic lookup according to 
SHLIB_PATH shell variable. Now when I move the library to different 
directory, dynamic linker is unable to find it (unless I use chatr 
utility to allow SHLIB_PATH lookup).

In fact my problem is little different. I have two libraries (OpenSSL), 
one dependent on another: libssl needs libcrypto. However, libssl does 
not have hardcoded path to libcrypto (both are in the same directory). 
When I create executable using both libraries, libtool hardcodes paths 
to these libraries into it. So far it looks good. However, when I run 
the executable, dynamic linker complains about libssl - it says it 
cannot find dependency library libcrypto. I think the problem here is 
that dynamic linker "thinks" libcrypto referenced from executable is 
different library than libcrypto referenced from libssl.

The solution here is to either pass +s linker flag or perform post-build 
step - "chatr +s enable" - for the executable (and any shared libraries 
which use OpenSSL and can be dlopened). I remember the discussions about 
this last year but I'm not sure about their result (chatr is not used in 
libtool). What is the right way to allow SHLIB_PATH lookup? Should this 
be solved by libtool or should I solve it manually (i.e. pass 
LDFLAGS=-Wl,+s)?

I use autoconf 2.57, automake 1.7.1 and CVS libtool:
ltmain.sh (GNU libtool) 1.4e (1.1210 2003/03/25 23:53:38)
