Programming :: Get Path Of One Library To Link It Dynamically In Program?
Apr 28, 2010I'd like to get path of one library to link it dynamically in my program. Probobly the best way would be to add macro to my configure.ac file.

Programming :: Link One Library Statically Others Dynamically - Gcc - G++
Jul 6, 2011I would like to make gcc to link one lib (pthread in the example) statically, and the rest dynamically.
(See the example .c file at the end of this post.)
compiles fine, but every lib is linked dynamically.
Now every lib is linked statically
Not a dynamic executable
I would like to link the libpthread statically and the rest dynamically. Is it possible?
[url]says if I give the full path to the .a lib then it will be linked statically:
So for me it does not work.
On other sites I found that I should use -Wl,-Bstatic -lpthread -Wl,-Bdynamic, but it also doesn't work:
So, how can I do that?

Programming :: Save / Load Data Segment Of Dynamically Loaded Shared Object Library?
Aug 25, 2010Our application uses a dynamically loaded shared object library (codec library) to compress and decompress audio streams.
There happens to be several static and global variables in this shared object library. Hence it is not possible to process two interleaved unrelated media streams using this shared object codec library because each stream corrupts/changes the contents of these static/global variables.
Is there a way through which a context save (save contents of data segment of shared object) and a context load (load previously saved contents of data segment of shared object)operation can be performed on the shared object library. This way the context for each media stream can be saved and loaded before and after processing the "other" media stream respectively.

Programming :: Specify A Library Search Path To Configure's AC_CHECK_LIB?
Aug 31, 2010I'm writing an application and want to make possible to compile it with or without an optional module. This module requires perl library to be compiled, so I want to check presence of it in 'autoconf'.
The problem exists because perl library is placed in 'non-standart' location itself (like a /usr/lib64/perl5/CORE/libperl.so). So when I try to run configure (with AC_CHECK_LIB or AC_SEARCH_LIBS), it cannot find and link libperl.so in its test.
Trying to pass ./configure CFLAGS=-L/usr/lib64/perl5/CORE/ or ./configure LDFLAGS=-L/usr/lib64/perl5/CORE/
How can I define a location to search for configure's tests?
Programming :: How To Change - Add To - Library Search Path At Runtime
Jan 9, 2011I'm writing an application with a plugin architecture and would like modify (specifically add to) the dynamic library search path while the main executable is running.
The plugin paths are not known until the application is running so I can't set LD_LIBRARY_PATH ahead of time.
My understanding (although I haven't tested it) is that the executable will only parse the LD_LIBRARY_PATH once, early on, so modifying this environment variable at runtime will have no effect.
(Note - on Windows the solution is to modify the PATH environment variable)
I know it's possible to specify the full path to load a dynamic library, and this would work if the plugin(s) only had a single library to load, but some of them will have a bunch of libraries with their own inter-dependencies, so I'd like the plugin folder(s) to get added to the search path to pick up the dependant libs.

View 2 Replies View RelatedGeneral :: Difference Between Static And Dynamically Linked Library?
Aug 30, 2010Libraries have always been ambiguous to me. I would love to have a clear understanding of them. Here's what I know so far... Ok I know that libraries are a bunch of functions and definitions in C that binaries use. I also understand that static libraries are used by the binaries in /sbin:/usr/sbin:/usr/local/sbin and dynamically linked libraries are used by the binaries in /bin:/usr/bin:/usr/local/bin So why have statically linked and dynamically linked libraries? I know that dynamically linked libraries are used to save space. Otherwise each binary would need its own private copy of a library. So dynamically libraries are used to save space.
1. Where are the static libraries and the dynamically linked libraries located in the file structure?
2. Where does ldconfig fit into all of this?
3. Would a rootkit affect both statically and dynamically linked libraries? I would think yes unless the libraries only have read permissions.
4. If the above is true, is there any reason for your libraries to have write permission other than when you want to edit them?

View 5 Replies View RelatedGeneral :: Link Shared Library Against Other Shared Library?
May 27, 2010I think that the solution is very simple, but I cannot reach this solution. I'm trying to build an B.so that uses A.so.
A.so is compiled using C;
B.so is compiled using C++;
Inside "Aso.h" file I'had declared:
Code:
#ifdef __cplusplus
extern "C" {
#endif
[code]....
There's no error to compile that, this library seems to be compiled correctly, but using the "nm" command the Aso.so functions appear with "U" of undefined. Trying to build an executable using the Bso.so library, I got this error: /lib/../lib/libBso.so: undefined reference to `foo(int, int, int)' I think that to solve this problem it's only link the Aso.so with the .o files generated at the compilation phase of my Bso. Using the "ldd" command I'm able to see that Bso.so depends on Aso.so, so what am I missing?

View 3 Replies View RelatedProgramming :: SDL Static Library - Shared Library ?
Apr 7, 2009I'm reading about shared, static, and dynamic libraries. What is SDL? Is it static, shared, or dynamic?
I always thought a library would be a lot of .h and .cpp files compiled separately into .o files and then if you compiled your own program you could use the -l parameter to link the library and it was all compiled together. Now I'm not so sure.
I don't even see any SDL .cpp files in my system anywhere. All I have are lots of SDL .h files in /usr/include/SDL and I don't really understand the code in them.
I'm making a wild guess here: SDL is a shared library. SDL itself is NOT compiled into my program, therefore SDL must be on any system my program tries to run on. When I compile and link SDL all it needs is the header files to know what SDL function and objects it can use. And then on every system it uses an already compiled SDL shared library thingy somewhere.
So... where is that part of SDL? All I can find are header files.
I'm thinking the advantage of shared libraries is that someone could say update SDL on their own system and take advantage of the new features without having to download new executables with the new version of SDL compiled into them for every program that uses SDL.
So if I'm making an editor and a game engine and they both use a lot of the same .cpp and .h files that I wrote and I'm tired of updating one and then the other and I need to turn them into a library, then a shared library might be kind of a silly solution. I could just make a static library. Right? Because it's not SDL. Nobody else is ever going to use this library.

View 2 Replies View RelatedProgramming :: Dynamically Loading Libraries In GNU?
Oct 22, 2010This post isn't really asking for a tutorial, but rather asking for some ideas. I've come up with a few ideas, but they seem cumbersome and unnecessary, so I was wondering if someone with more experience than me could out. Also, my explanations suck, but I'll try to do my best. So say I have an executable called X. At some point during its execution, X loads and uses (using dlopen and dlsym) a library called Y. In Y, there a bunch of functions that call the function called, for example, void *special_malloc (size_t). These functions come from another linked library (linked during compilation) called Z. Problem is, special_malloc contains some static variables within its scope, and when those variables are reset midway through a program, an invalid free occurs (special_malloc uses garbage collection). Now, what I want to happen is that whenever lib Z calls special_malloc, it instead calls the special_malloc defined in the executable X, so that these static variables are retained. Keep in mind that I have control of the Z library, meaning I can edit the source to fit my needs.
View 2 Replies View RelatedProgramming :: Link Directories - Symlink Not Updated / Hard Link Not Supported?
Sep 6, 2010In the ordering of files I keep I need links to directories. Sometimes I even need to move directories to new locations. I have tried using symlinks, but they become dead when I move the directory they point to. I have tried hard links, but I haven't found any Linux file system that would support hard linked directories. How can I achieve that a complex structure of directories (currently with symlinks for directories and hard links for files) keep symlinks live when directories are moved?
- is there any utility that updates symlinks when a directory is moved?
- is there any Linux filesystem that supports hard linked directories?
- is there any good Linux interface to the new NTFS (the only file system I know to support automatically updating directory links, called directory junctions)?
