The OS is ubuntu 9.10 and Linux kernel is Linux ubuntu 2.6.31-17-generic. The compiler I'm using is gcc version 4.4.1, the linker is GNU ld (GNU Binutils for Ubuntu) 2.20`and the dynamic loader is ld-2.10.1.so. I did not use lazy loading. The source codes are very simple.
The source code of executable is foo.c, it only calls bar1 of the shared library.
The shared library only contains one object file (bar.o). The source code of bar.c is shown below. The reason I wrote so many functions was that I wanted to make the hash table and symbol table extremely large, because I thought that before any functions were called, these two tables should be loaded in the physical memory.
The commands I used to compile and link are:

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 have never seen this issue before, but here is what is happening. I link an executable against two dynamic mlib libraries veclib and lapack. We place a newer version of these libraries in a write only directory and point the shlib_path at that directory. When the executable runs, it gets a... (3 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 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.

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)

sdl-config
sdl-config(1) General Commands Manual sdl-config(1)NAME
sdl-config - script to get information about the installed version of SDL
SYNOPSIS
sdl-config [ --prefix= DIR] [ --exec-prefix= DIR] [ --version ] [ --libs | --library-libs | --plugin-libs ] [ --cflags ]
DESCRIPTION
sdl-config is a tool that is used to configure and determine the compiler and linker flags that should be used to compile and link pro-
grams, libraries, and plugins that use SDL. It is also used internally by the m4 macros that are included with SDL.
OPTIONS --cflags
Print the compiler flags that are necessary to compile a program or library that uses SDL.
--exec-prefix=DIR
If specified, use DIR instead of the installation exec prefix that SDL was build with when computing the output for the --cflags,
--libs, --library-libs, and --plugin-libs options. This option must be specified before any of the --cflags, --libs, --library-
libs, and --plugin-libs options.
--libs Print the linker flags that are necessary to link a program that uses SDL.
--static-libs
Print the linker flags that are necessary to statically link a program that uses SDL.
--library-libs
Print the linker flags that are necessary to link a library that uses SDL. (This excludes any static objects required for linking,
since these must be linked only by executable programs.)
--plugin-libs
Print the linker flags that are necessary to link an SDL-using object that is to be accessed via dlopen(3). This may include static
objects with PIC symbol information. This option should not be used for ordinary shared libraries or standalone applications.
--prefix=DIR
If specified, use PREFIX instead of the installation prefix that SDL was built with when computing the output for the --cflags,
--libs, --library-libs, and --plugin-libs options. This option is also used for the exec prefix if --exec-prefix was not specified.
This option must be specified before any of the --cflags, --libs, --library-libs, and --plugin-libs options.
--version
Prints the currently installed version of SDL on standard output.
EXAMPLES
gcc -o main.o $(sdl-config --cflags) main.c
is how you might use sdl-config to compile a C source file for an executable program.
gcc -o my_app $(sdl-config --libs) main.o util.o
is how you might use sdl-config to link compiled objects into an executable program.
gcc -o libSDL_nifty-1.2.so.0.0.1 $(sdl --library-libs) read.o write.o munge.o
is how you might use sdl-config to link compiled objects into a shared library.
gcc -o libnifty_xmms.so $(sdl --plugin-libs) stream.o blit.o deinterlace.o
is how you might use sdl-config to link compiled objects into a plugin for use by another program.
