Hi All
I have been given by someone else header file and a shared library to be used by my C++ application. Compilation is fine but when I try to executes the application I receive the following error.
Is there any way to force the application to dynamically link with this library without any extra step like installing it on the machine?
Thanks
HI,
I am dynamically loading shared libraries using shl_load(). There are multiple processes (50 or more) which loads the same shared library. Will Unix internally load only one copy of the shared library or it will load multiple copies.
Can I have memory issues if this is done.

I need to create a shared library to access an in memory DB. The DB is not huge, but big enough to make it cumbersome to carry around in every single process using the shared library. Luckily, it is pretty static information, so I don't need to worry much about synchronizing the data between... (12 Replies)
I am writing a shared library in Linux (but compatible with other UNIXes) and I want to allow multiple instances to share a piece of memory -- 1 byte is enough. What's the "best" way to do this? I want to optimize for speed and portability.
Obviously, I'll have to worry about mutual exclusion. (0 Replies)
I am debugging in gdb a program that dynamically loads libodbcinst.so. I want to debug the code from libodbcinst - I can break in it, see the source and step through it, but whenever I try printing a variable, I get (e.g. for the variable ret):
No symbol "ret" in current context.
In my program... (0 Replies)

Hi:
I have a library that it only offers Makefile for building static library. It built libxxx.a file. How do I in any way build a shared library? (either changin the Makefile or direct script or command to build shared library)

Hi,
I have an application running on AIX. The app is deployed on Webspshere server. Due to some reason, i have to make use of a third party library (Sigar API's) from my application. This library requires an .so file as well.
Is there any location where i can put this *.so file and it will... (1 Reply)
Hello.
I am new to this forum and I would like to ask for advice about low level POSIX programming.
I have to implement a POSIX compliant C shared library.
A file will have some variables and the shared library will have some functions which need those variables.
There is one special... (5 Replies)

libdl
libdl(3LIB) Interface Libraries libdl(3LIB)NAME
libdl - dynamic linking library
SYNOPSIS
cc [ flag... ] file... -ldl [ library... ]
DESCRIPTION
Historically, functions in libdl provided for dynamic linking support. This functionality now resides in libc(3LIB).
This library is maintained to provide backward compatibility for both runtime and compilation environments. The shared object is imple-
mented as a filter on the runtime linker. See ld.so.1(1). New application development need not specify -ldl.
INTERFACES
The shared object libdl.so.1 provides the following public interfaces. See intro(3) for additional information on shared object interfaces.
dladdr dladdr1
dlclose dldump
dlerror dlinfo
dlmopen dlopen
dlsym
FILES
/lib/libdl.so.1 shared object
/lib/64/libdl.so.1 64-bit shared object
