I have a problem with GLEW Library, I have a Linux system and I compiled a program with GLFW and GLEW but if I start my program it causes problems.
It outputs this:
./Test: error while loading shared libraries: libGLEW.so.2.0: cannot open shared object file: No such file or directory
I wrote a bash script with following code:
#!/bin/sh
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:~/Dokumente/Libraries/glfw-3.2.1-build/src/libglfw.so.3:~/Dokumente/Libraries/glew-2.0.0/lib/libGLEW.so.2.0
export LD_LIBRARY_PATH
./Test
But it doesn't work. It outputs the same error and I am sure the path is right
What can I do?
You can also allow loading of .so's from the same folder the executable is at "Windows Style" by setting the rpath with patchelf:
patchelf --set-rpath '$ORIGIN' your_program_binary
If you want to do this is up to you, of course. ;)
I have just solved the problem:
I put all Libraries into /usr/local/lib and change the LD_LIBRARY_PATH to this

I tried to run a program that requires log4cpp,
I got following error when I try to run the program
error while loading shared libraries: liblog4cpp.so.4: cannot open shared object file: No such file or directory
I have set the library path in $LD_LIBRARY_PATH and these are the files in my /usr/local/lib directory:
liblog4cpp.a
liblog4cpp.so
liblog4cpp.so.5.0.6
liblog4cpp.la
liblog4cpp.so.5
pkgconfig
What could be the problem here ?
Thanks!
Use
ldd [program name]
so see what's actually loaded (assuming you are on a Unix system since you use LD_LIBRARY_PATH).
I'm trying to build the SDL library from the source code. I've downloaded the compressed file (i.e. SDL2-2.0.3.tar.gz) and extracted it. I don't want to install the files in /usr/local. According to this link, I need to change the configure
The last command says "sudo" so we can write it to /usr/local (by
default). You can change this to a different location with the
--prefix option to the configure script. In fact, there are a LOT of good options you can use with configure! Be sure to check out its
--help option for details.
This is what I've done.
mkdir build
cd build
../configure
make
sudo make install
In install folder that I've created are the following files
share
lib
include
bin
Now I would like to run the test files. I've picked this testatomic.c and this is the command line
gcc testatomic.c -o test -I/home/xxxx/Desktop/SDL2-2.0.3/install/include/SDL2 -L/home/xxxx/Desktop/SDL2-2.0.3/install/lib -lSDL2 -lSDL2main
I get this error
error while loading shared libraries: libSDL2-2.0.so.0: cannot open shared object file: No such file or directory
In lib, these are the files
Where is the shared object file?
You're getting error when running resulting program because system's dynamic linker cannot find required library. Program requires libSDL2-2.0.so.0, linker looks for it in system-defined directories (/lib, /usr/lib, ..., - defined in /etc/ld.so.conf), but finds none - hence an error.
To inform linker where you want it to look for libraries, you can define LD_LIBRARY_PATH environment variable, e.g. in your case:
export LD_LIBRARY_PATH="$HOME/Desktop/SDL2-2.0.3/install/lib"
./test
Other ways is installing libraries in standard location, defining LD_LIBRARY_PATH in your .bashrc (or whatever shell you use), or using rpath, e.g. adding -Wl,-rpath=$HOME/Desktop/SDL2-2.0.3/install/lib at the end of your compilation line.
I was able to fix this problem with:
sudo apt install libsdl2-dev
I too had:
./01_hello_SDL: error while loading shared libraries: libSDL2-2.0.so.0: cannot open shared object file: No such file or directory
as a result of compiling the first C++ program (using the SDL headers) as part of the Lazy Foo tutorial. I found out that libSDL2-2.0.so.0 was just using the find command in the GUI. It turned out to be in /usr/local/lib
Then in terminal I typed:
export LD_LIBRARY_PATH="/usr/local/lib"
I checked the value of LD_LIBRARY_PATH using:
echo $LD_LIBRARY_PATH
I recompiled (don't know if that was necessary) and voila, it worked.
I use gsl.
After I compiled my .cpp file and run it, I faced with below error:
error while loading shared libraries: libgsl.so.0: cannot open shared object file: No such file or directory
I found same as this problem in:
https://groups.google.com/forum/#!topic/cortex_var/6vluX7pP0Sk
&
Linux error while loading shared libraries: cannot open shared object file: No such file or directory
&
http://www.gnu.org/software/gsl/manual/html_node/Shared-Libraries.html
And I have done as in the above links wrote but the error is still remained.
Can anyone help me?
To make it work do the following steps
Start Borne Shell
$LD_LIBRARY_PATH= path to your gsl lib folder inside the gsl installation folder
$export LD_LIBRARY_PATH
now run your executable
It should work fine.
First, you need to locate the file (libgsl.so.0). You can do this, for example, by using the find command:
sudo find / -name "libgsl.so.0"
Let us assume, the file is located in /usr/local/lib.
(If the file has not been found, install the corresponding package or download the source, build it and install it.)
Now, you have two options:
(1) Quick & Dirty:
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
export LD_LIBRARY_PATH
This adds the path of the library to an environment variable. The disadvantage of this option is, that it is only valid for the current session. It will not work for other users. It will not work once you log off and on again.
(2) Permanent:
Review your /etc/ld.so.conf. If /usr/local/lib is not listed there, add it. Now, run ldconfig to detect the shared object file and add it to some system-wide index.
I got the same error with Krita on Arch Linux. I made a symlink with
ln /usr/lib/libgsl.so /usr/lib/libgsl.so.0
and that fixed it.
In my experience, fastStructure depends on gsl 1.6 but not the latest version.
wget http://gnu.mirror.vexxhost.com/gsl/gsl-1.6.tar.gz
tar -zxvf gsl-1.6.tar.gz
cd gsl-1.16
./configure
make
sudo make install
Add these lines to your .bashrc file on your home directory.
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
export CFLAGS="-I/usr/local/include"
export LDFLAGS="-L/usr/local/lib"
then, run source ~/.bashrc to set these environment variables.
It works fine when I change the version from the latest to the 1.6.
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/shg047/software/gsl/lib/
such as: to-mr: error while loading shared libraries: libgsl.so.19: cannot open shared object file: No such file or directory
Have you tried updating your library? The program I was trying to run simply needed a newer version of gsl (I had 1.9.5 while it needed 2.0.0 or newer).
If you are on arch you can run:
yaourt gsl
and select the appropriate one.
You can use gsl-config --libs in you makefile or in the command line when you link the gsl library. Just type gsl-config you can find the options it offers to you. Choose the options you need, you will find compile and link process much easier than before. As a result, when I type gsl-config --libs in my terminal, I get -L/usr/local/lib -lgsl -lgslcblas -lm. Although it is very simple, first you should know where you gsl is installed. You can add the directory to the PATH environment variable or use the absolute path to execute gsl-config .
I needed libgsl.so.19:
/snap/inkscape/current/bin/inkscape: error while loading shared libraries: libgsl.so.19: cannot open shared object file: No such file or directory
I solved it with:
Installing Anaconda
searched for libgsl.so.19 and found it in ~/anaconda3/lib
run LD_LIBRARY_PATH=$LD_LIBRARY_PATH:~/anaconda3/lib (best add it to ~/.basrc)
I'm writing a method for Oracle in C++. I’m using the OCI library with Eclipse as my IDE. The code compiled completely but I’m getting this runtime error:
"error while loading shared libraries: libocci.so.11.1: cannot open shared object file: No such file or directory "
I included occi and clntsh and nnz11 through properties > c/c++ general /Path and symbols > libraries
I don't know how to fix this error, please help thanks you
IDE wont take like libocci.so.11.1
you have to convert into like libocci.so
ln -s libocci.so.11.1
then it will be renamed to libocci.so
then compile the code
Your compiler finds the libraries because your project probably specifies where to look for libs (-L flag on the linker command line). But the runtime linker needs to find the libs as well.
I assume you're running it on linux. You have 2 options:
A temporary solution is to define in your environment LD_LIBRARY_PATH=full path to dir where libocci.so* is installed. I'm not very familiar with eclipse, but there's likely a setting to change the runtime environment. You could also set LD_LIBRARY_PATH and then run ecplise in that env.
$ export LD_LIBRARY_PATH=...
$ command to run eclipse
A permanent solution is to add the full path to the dir. where the libs are to the file /etc/ld.so.conf, or better: create a file /etc/ld.so.conf.d/oracle and put the path in that file, nothing else. Then, as root, run ldconfig.
wow . finally i did it , by one variable and put it into .bashrc
1- export LD_LIBRARY_PATH=/opt/oracle/instantclient "The Path of libraries" and then
2- root#user:~# vi .bashrc "Make sure you are in root"
3- LD_LIBRARY_PATH=/opt/oracle/instantclient/ "Add this two lines into file"
export LD_LIBRARY_PATH
:)
I have a project organized as
\bin\cmain
\lib\libxmlrpc_client++.a
\lib\libxmlrpc_client++.so.4
\lib\libxmlrpc_client++.so.4.16
My c program cmain need to dynamically link clib.so.4. While I compile the code, I use -L.../lib to indicate directory lib and use -lxmlrpc_client++. However, my code get error while loading shared libraries:
libxmlrpc_client++.so.4: cannot open shared object file: No such file or directory
Any ideas to fix this?
PS: Problem solved, a good reference to the problem: http://gcc.gnu.org/ml/gcc-help/2005-12/msg00017.html
You need to tell the dynamic linker where to look for the libraries. Assuming this is some sort of UNIX/Linux system, this can be done either via setting the LD_LIBRARY_PATH environment variable before executing the program:
export LD_LIBRARY_PATH=/path/to/lib
./run-my-program
or by setting the run-time linker path during compile time:
gcc -L/path/to/lib -Wl,-rpath,/path/to/lib -lxmlrpc_client++ ...
./run-my-program
Both approaches have problems. Google for "why LD_LIBRARY_PATH is bad". The command-line options for setting the run-time linker path varies from one compiler to another.
You should use -Llib instead of -L..
Is that softlink broken? ls -l, make sure your pointing to the correct file.
Example Error :
[root#localhost ~]# ./conn 127.0.0.1 6379 opencc ./conn: error while
loading shared libraries: libhiredis.so.1.0.3-dev: cannot open shared
object file: No such file or directory
Solution
The problem was the libhiredis wasn't in the ldconfig path. While the build process was correct and it copied everything to the correct directory ldconfig did not know about its location.
You can use ldconfig -p to see all library ldconfig currently know about.
You can add the path to ldconfig with
sudo echo "/usr/local/lib" > /etc/ld.so.conf.d/local.conf
&
sudo ldconfig
