General :: Static Versus Shared Libraries (Linking C Program With GCC)
Mar 16, 2010
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?

I 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
[code].....
Why would gcc claim that I'm missing GLUT? This works perfectly fine when I do dynamic linking -- i.e. omitting the -static argument.

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

Is there any way to use a dynamic libraries as a static libraries instead when compiling, so that my resulting executable won't have them as dependencies?

I have a library that I have ported from Windows, and is not a derivative work of Linux. The library is subject to copyright law, and I can't disclose the source. I would like to link a GPL application to this library, and want to know if the linking would cause the library to be GPL. If the library becomes GPL, is there some other way (kernel loadable module?) that I can keep my library from becoming a work of GPL?

After I downloaded the source for lua, I followed the install instructions, doing...
make linux install
make generic install
I've also done the make test and it passes, printing out Hello World, from Lua 5.1. However, I can't link to the lua libraries in CodeBlocks. I know where lualib.a is (usr/local/lib) which I set in my Search Directories for the linker. I still get error messages like...
undefined reference to lua_isstring
P.S. I had this running on Windows via Visual Studio.

I am running Fedora 13 on a ASUS G71G Trying to install GTK+ 2.4.8; after installing all the dependencies(Pango, Glib2.0, ATK), I ran ./configure from my GTK+ directory. It configured for a while, then this happened: checking for X... no configure: error: X development libraries not found I tried linking them with PKG_CONFIG_PATH=<path to X lib directory>, but I got the same error message. How do I get GTK+ to recognize the X development libraries? Additionally, does the default build of X11 on Fedora 13 contain the appropriate libraries? Ive included the GTK+ configure scripts as an attachment.

I have an application consisting of different processes and all these processes are linked to shared libraries. I start the application (spawn all the different processes) as say user1. Now with the application up, if I run a process p1, the process gets activated and works. However, if I start the same process p1 as a different user, say user2, which is completely different from user1 the process complains of
"error while loading shared libraries:...."
I set LD_RUN_PATH both in compile and runtime environment. LD_LIBRARY_PATH is set correctly in both places.
All the above works if I set the absolute path of the required shared libraries in /etc/ld.so.conf file and rebuild the /etc/ld.so.cache

Alright, just loaded a fresh copy of OpenSuSE 11.3 x64, went to update manager and let it update, came back and computer was shut down. After booting it back up, I cannot update any software, nor run any commands.
Here is my output:
Code: error while loading shared libraries: libdl.so.2: cannot open shared object file: No such file or directory I've tried searching for this error, some people came back saying to run this:
Code:
But all that happens is this:
Code:
Nor ls work either so I'm stuck and thinking about a reinstall.
I don't understand how this system could be so messed up after a failed update.. Used to trust SuSE, not sure anymore after this incident..

I'm trying to run Kega Fusion on my laptop, which can now FINALLY run Linux (ATI drivers finally work on it), and I can't get the emulator to work..
Code:
brandon@brandon-laptop:~/Desktop/Fusion$ ./Fusion
./Fusion: error while loading shared libraries: libGLU.so.1: cannot open shared object file: No such file or directory
brandon@brandon-laptop:~/Desktop/Fusion$ uname -a
Linux brandon-laptop 2.6.32-24-generic #38-Ubuntu SMP Mon Jul 5 09:20:59 UTC 2010 x86_64 GNU/Linux
brandon@brandon-laptop:~/Desktop/Fusion$
Help? I have the ATI proprietary drivers installed. I tried without them and it still wouldn't work. (And OpenGL is seemingly working as Compiz Fusion is running. I also tried with Compiz disabled but the same error pops up).

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. (I did a full install from the DVD, not deselecting anything, and when I upgraded to -current, I also did the same.)
Ark said:
Quote:
ark: error while loading shared libraries: liblzma.so.0: cannot open shared object file: No such file or directory
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:
Quote:
kate: error while loading shared libraries: libkemoticons.so.4: cannot open shared object file: No such file or directory
Now, konsole, firefox, and Chromium's errors are a little different.
Konsole:
Quote:
konsole: symbol lookup error: /usr/lib/libphonon.so.4: undefined symbol: _ZN9QMetaType15registerTypedefEPKci
Firefox and Chrome basically say the same thing
Quote:
/usr/lib/firefox-3.6.13/firefox-bin: symbol lookup error: /usr/lib/mozilla/plugins/skypebuttons.so: undefined symbol: _ZN9QListData11detach_growEPii
again, I am completely baffled here, as I had kate, konsole and ark running before I upgraded to -current.

My principle machine is Ubuntu 10.10 (x86_64) with gcc version 4.4.5, but I'd like to run the compiled/linked code from it on a RHEL server release 5.4 with gcc version 4.1.2.
Now, the error at runtime is "version 'GLIBCXX_3.4.9' is not found (required by ./executable)". The server has /usr/lib64/libstdc++.so.6.0.8, but seems to need at least .so.6.0.9. However, the admin of the server will not allow the libraries to be updated as "the entire system is tied to an older version of glibc and forcing an upgrade could break the entire system especially when making the jump across major revisions."
He recommended that I build the newer version of glibc in my home directory and link against the libraries, but didn't offer direction on how.

I have an old program that kind of depends on older dynamic libraries. They tend to get upgraded easily with distro's updates. I figured that there would be a script with using ldd that would gather the libs needed and create one bigger, statically linked application that wouldn't break so easily. If I could do this, a lot of older KDE libraries could be removed from my system and easen my life.
My distribution of choice is gentoo, but I'm looking for a general solution that doesn't depend on rebuilding anything. If it runs with libs on their path, I'm sure it can be made run with libs somewhere else!

I would like to ask you something about open-source and linux. Is it possible to make a commercial application for linux and sell it compiling it with linking to open-source libraries without altering them and consequently without allowing download of the source code and without making the application itself free?

There's a problem with static linking (and no problems with dynamic linking).
Here's my code:

And makefile rule:

That's dynamic linking. And it works perfectly. If i use static linking
Quote:
There is an undefined reference error:
Quote:
As nm shows there's a symbol named BuzzerInit in static library.

A newbie trying his hand with openldap.Disclosure: I tried posting at openldap forum, but my message does not appear in the mailing list-- and I didn't receive anything back from that forum, so please don't flame.I use red hat 5.5.I didn't want to use the openldap that is bundled with and installed by the red hat, so I downloaded and installed BerkeleyDB-4.8.30 and openldap-2.4.23.
I can see that the file libdb-4.8.so is in /usr/local/lib and /usr/local/lib is in my path (in my .bashrc).. so why not "read" it from there?How do I solve this problem?

Basically, I'm trying to compile program A, which depends on LibA and LibB. LibA would not build with my version of G++ 4.4.3 due to a bug, so I've compiled the latest G++ 4.5 (installed in /opt directory) and built that library successfully (also installed in /opt).
I have LibB on my system already, but it was built with the 4.4.3 version. When compiling my final program, am I going to have issues because the .so files were built with different versions of gcc/g++? Or should I just rebuild a special version of LibB with the later version of the compiler just for that program? I can proceed and just see what happens, but I'm a little confused about how things work in a situation like this.

During installation of BACCardI (genome assembly validation software), in the final step, we get an error: <baccardi.bin:error while loading shared libraries libqt-mt.so.3: cannot open shared object file: No such file or directory>. So, to fix it, we tried installing the i386 libqt using command <sudo apt-get install libqt3-mt_3.3.6-1ubuntu3_i386>
But, now we get:

The problem is when i'm trying to run the console application of my compiler. i have a menu.c from which i choose different modes and i operated on that.
When i tried to open one of the executable i'm getting this error:

I am trying to create a package for Moblin using the Moblin Package creator application in Ubuntu. The RPM package gets created successfully, but when I execute that package in Moblin OS in the terminal I get the following error message: Error while loading shared libraries: libgda-4.0.so.4: cannot open shared object file: No such file or directory.
I understand that the above libraries are missing on my system and I need to add them. My question here is do I have to add them manually after the installation of the package or can the package itself include these libraries and copy them to proper locations when the package is installed. In case the libraries can be included in the package I want to know how that can be done.

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..
