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)
Thanks. (1 Reply)
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)

apr-1-config
APR-1-CONFIG(1) User Commands APR-1-CONFIG(1)NAME
apr-1-config - Return metainformation about apr library
SYNOPSIS
apr-1-config [OPTION]
DESCRIPTION
The apr-1-config program is used to retrieve information about the apr library in the system. It is typically used to compile and link
against the library.
When linking with libtool, an application should do something like:
APR_LIBS="`apr-1-config --link-libtool --libs`"
or when linking directly:
APR_LIBS="`apr-1-config --link-ld --libs`"
An application should use the results of --cflags, --cppflags, --includes, and --ldflags in their build process.
OPTIONS
Known values for OPTION are:
--prefix[=DIR]
change prefix to DIR
--bindir
print location where binaries are installed
--includedir
print location where headers are installed
--cc print C compiler name
--cpp print C preprocessor name and any required options
--cflags
print C compiler flags
--cppflags
print C preprocessor flags
--includes
print include information
--ldflags
print linker flags
--libs print additional libraries to link against
--srcdir
print APR source directory
--installbuilddir print APR build helper directory
--link-ld
print link switch(es) for linking to APR
--link-libtool
print the libtool inputs for linking to APR
--shlib-path-var
print the name of the shared library path env var
--apr-la-file
print the path to the .la file, if available
--apr-so-ext
print the extensions of shared objects on this platform
--apr-lib-target
print the libtool target information
--apr-libtool
print the path to APR's libtool
--version
print the APR's version as a dotted triple
--help print the help
