HP-UX

Hi, I am new to unix. But, I write programs in progress that run on an HP-UX.

We are running a program and it is looking for the file /lib/libz.so.1

Naturally, we do have ZLIB 1.2.3 installed, and I can only find files called
libz.sl.1
libz.a
libz.sl.1.2.3

None of these files are correct, what I need is the shared library file, if I can't find this, how can I get this program to work.

Thanks.

Whatever you are running was linked against a foreign shared library that you do not have. You cannot guarantee that libz.sl has the same entry points or functionaility.

Code:

ldd myapp

will show you what it was linked against. If there are a lot of "so" files you have a big problem. You probably have an exe that was meant to run on a different system.
PA RISC HP systems try to run ELF format files, if they recognize them. "so" files are found in Linux, for example.

I would seriously consider rebuilding the application from source.

If your code absolutely does not do anything but make reports I guess you could try creating a symbolic link in /usr/lib named "libz.so.3" that it points to "libz.sl.1" -- note this is not the best possible idea.

Thanks for the reply Jim,

I have re-installed zlib, and noticed that libz.sl was now created in the /usr/local/lib directory, which it wasn't before.

But, I wanted to know are .so and .sl files that zlib create the same, in terms of functionality.

Thanks
