Problem in porting

[abp]

I am trying to port an application from NT to HP-UX10. Now I am using aCC
as the compiler and linker (path - /opt/aCC/bin/aCC). This program has 2 parts. An executable and shared library which is loaded at run-time. The shared library is also needed to satisfy some symbols during linking. In the run-time, the shared library is put in a directory which is included in the SHLIB_PATH. My problem is that, during linking, the linker is adding the absoulte path of the shared library to the executable. So when I run the executable elsewhere, it can't find the shared library cuz that path
of course is unique to the development set-up. So the program fails and core dumps.
What i need is some linker options to tell the linker not to add the abs path of the
SL to the executable. Guys, i am new to the forum and I will be very happy if i fix this in a day or two. thanks- Anand Pillai [sig][/sig]

Hi,

Is there an option to "statically link" rather than "dynamically link" your executables?

That would create larger executable files, but they *would* work... [sig]<p>Mike<br><a href=mailto:michael.j.lacey@ntlworld.com>michael.j.lacey@ntlworld.com</a><br><a href=

I can't remember if this is available under HP-UX, but can you set LD_LIBRARY_PATH so that it includes the directory containing your shared library? The syntax is the same as PATH, so if it's already set just add your new path after a &quot;:&quot;.

On other Unix versions, LD_LIBRARY_PATH sets the locations to search for shared libraries. It might be worth trying. [sig]<p> Andy Bold<br><a href=mailto: > </a><br><a href= > </a><br>"I've probably made most of the mistakes already, so hopefully you won't have to..." Me, most days.[/sig]

I found the solution after a bit of R&D. In the makefile, you have to give this
option to the linker.

LD_FLAGS = -Wl, +s

This will invoke the subprocess 'l' (the linker) with argument +s which means,
&quot;look for the shared library in the LD_LIBRARY_PATH, instead of taking the absolute
path.&quot; ( man ld(1))

Thanks for the help...
