I'm building a static library (openssl) and linking with a shared library. I built openssl static library with out -fPIC option and in the makefile of shared library there is an option of -fPIC. When I'm compiling shared library with static library, I'm not getting any relocatable error, since static library is not built with -fPIC and shared library is compiling with -fPIC.
GCC version : gcc 4.0.4
OS : CentOS 5.2
I have a third party static library (libSTATIC.a) that I cannot recompile into a shared library. I want to create a shared library (libSHARED.so) that uses the C functions in the static library. Is it possible to do this? In other words, when linking a C program with gcc by using the -shared flag, is it necessary that all all libraries invoked in the program (even low level libraries such as libc for example) be available as shared libraries as well?
View 2 Replies View RelatedI have written an OpenGL based program which uses i.a. libjpeg that I want to link statically so I can send it to someone who doesn't have all the libraries needed installed to allow for a dynamically linked executable to run. As such I tried with giving the [b]-static[b] parameter to gcc.
Code:
x86_1$ make
gcc -O3 -c jpegloader.c
gcc --std=c99 -O3 -c --std=c99 -I/usr/include -L/usr/X11R6/lib main.c

Why would gcc claim that I'm missing GLUT? This works perfectly fine when I do dynamic linking -- i.e. omitting the -static argument.
There's a problem with static linking (and no problems with dynamic linking).
Here's my code:

That's dynamic linking. And it works perfectly. If i use static linking

There is an undefined reference error:

As nm shows there's a symbol named BuzzerInit in static library.
I have a question about shared objects and when mapping and linking is established in the following code...Well more of a verification.
getsetx.c - shared object source code Code: unsigned long x = 0;
unsigned long getx(void)
{
return x;
}
[Code].....
Now its my understanding when I execute ./testit, getsetx.so will get mapped into its address space at start up and testit will link any functions as they are needed..
I am creating two shared libs that i intend to be dynamically linkable in C and C++, cross platform Linux/Windows/Mac. As a basic sketch, true for both libs, the lib code is in several .c/.cpp and .h files. For now, I'll talk about the part that I am actively working on, a lib named Discover, i.e. libdiscover.so.1.0. First, everything is in a namespace, RemKon_Discover.
The main Discover.cpp defines the methods for the Discover class (declared in Discover.h) and has extern "C' routines that can return pointers to my main c++ object. The call to GetLibraryMainPointer() creates a Discover class object, theMainObject (ok, I win a prize for dumb names) and returns the (non-mangled) pointer to the caller over in my test program. The Discover class itself is declared extern "c" and the tester program #includes "Discover.h".
In the test program, dlopen() correctly opens the lib and dlsym() gets the pointer to theMainObject. However, when I use that pointer in the tester program to access a method (aDiscoverObject->hello(), e.g.) I get compile time errors saying that Discover::hello() in an undefined reference. My makefile is attached.

My code needs to link to some libraries. In my project file, I specify linker to link to abc library, for example. By default, does gcc link to libabc.a or libabc.so ? What if I really need to specify static or shared, how do I do that?
View 4 Replies View RelatedI don't use wireless tools myself currently, since I'm wired to the internet; but, I found that a package I wanted to build, required at the least, a shared version of libiw, if not both the shared AND static version. Symptoms of when you are in this boat, are error messages during compiling, similar to:

I'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.
I have created a Fedora 11 image with the GUI stripped out that autoboots into a mainframe terminal emulation program(c3270). I have everything working except for a print screen function. I have made a little script that will dump the screen from tty3 and send it to a printer, but I have no way for the end user to run this without giving them access to a terminal and I do not want them playing with that. So I was wondering if anyone knew a way to link the running of a script to a keybinding. That way all they have to do is hit Print Screen or some alt + key combo to get the screen capture.

I have a dual boot system. I previously managed to mount that drive under Fedora by specifying its label in /etc/fstab. But something changed that label, so I had to modify the entry in fstab. This time, using blkid I found the proper UUID and put that in /etc/fstab. So now I can mount the partition. But I also want to create a link on my desktop to my files under Windows.The location is /mnt/c/Documents and Settings/len/My Documents But ln -s keeps failing on that because of the spaces in the name. I know I found a workaround that previously , but I can't remember what it is.

After finally getting my wireless/graphics drivers working yesterday (thanks to this forum ) I startx to realize that not a single KDE/Qt application will launch, along with Firefox, or Chrome/Chromium.

Ark said:

but I managed to fix that one by commenting out 'aaa_elflibs' in /etc/slackpkg/blacklist (on a recommendation from #slackware), and running slackpkg upgrade-all again, but that's the only one (afaik) that was fixed. Ark still doesn't work, but it doesn't show that error anymore. When I run it, a box pops up that says "Unable to find Ark's KPart component, please check your installation."
Kate still says:
