Is the .1 at the end part of the filename? What does that mean anyway?
Your library is a dynamic library.
You need to tell the operating system where it can locate it at runtime.
To do so,
we will need to do those easy steps:
Find where the library is placed if you don't know it.
sudo find / -name the_name_of_the_file.so
Check for the existence of the dynamic library path environment variable(LD_LIBRARY_PATH)
echo $LD_LIBRARY_PATH
If there is nothing to be displayed, add a default path value (or not if you wish to)
LD_LIBRARY_PATH=/usr/local/lib
We add the desired path, export it and try the application.
Note that the path should be the directory where the path.so.something is. So if path.so.something is in /my_library/path.so.something, it should be:
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/my_library/
export LD_LIBRARY_PATH
./my_app
Reference to source
Here are a few solutions you can try:
ldconfig
As AbiusX pointed out: If you have just now installed the library, you may simply need to run ldconfig.
sudo ldconfig
ldconfig creates the necessary links and cache to the most recent
shared libraries found in the directories specified on the command
line, in the file /etc/ld.so.conf, and in the trusted directories
(/lib and /usr/lib).
Usually your package manager will take care of this when you install a new library, but not always, and it won't hurt to run ldconfig even if that is not your issue.
Dev package or wrong version
If that doesn't work, I would also check out Paul's suggestion and look for a "-dev" version of the library. Many libraries are split into dev and non-dev packages. You can use this command to look for it:
apt-cache search <libraryname>
This can also help if you simply have the wrong version of the library installed. Some libraries are published in different versions simultaneously, for example, Python.
Library location
If you are sure that the right package is installed, and ldconfig didn't find it, it may just be in a nonstandard directory. By default, ldconfig looks in /lib, /usr/lib, and directories listed in /etc/ld.so.conf and $LD_LIBRARY_PATH. If your library is somewhere else, you can either add the directory on its own line in /etc/ld.so.conf, append the library's path to $LD_LIBRARY_PATH, or move the library into /usr/lib. Then run ldconfig.
To find out where the library is, try this:
sudo find / -iname *libraryname*.so*
(Replace libraryname with the name of your library)
If you go the $LD_LIBRARY_PATH route, you'll want to put that into your ~/.bashrc file so it will run every time you log in:
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path/to/library
Update
While what I write below is true as a general answer about shared libraries, I think the most frequent cause of these sorts of message is because you've installed a package, but not installed the -dev version of that package.
Well, it's not lying - there is no libpthread_rt.so.1 in that listing. You probably need to re-configure and re-build it so that it depends on the library you have, or install whatever provides libpthread_rt.so.1.
Generally, the numbers after the .so are version numbers, and you'll often find that they are symlinks to each other, so if you have version 1.1 of libfoo.so, you'll have a real file libfoo.so.1.0, and symlinks foo.so and foo.so.1 pointing to the libfoo.so.1.0. And if you install version 1.1 without removing the other one, you'll have a libfoo.so.1.1, and libfoo.so.1 and libfoo.so will now point to the new one, but any code that requires that exact version can use the libfoo.so.1.0 file. Code that just relies on the version 1 API, but doesn't care if it's 1.0 or 1.1 will specify libfoo.so.1. As orip pointed out in the comments, this is explained well at here.
In your case, you might get away with symlinking libpthread_rt.so.1 to libpthread_rt.so. No guarantees that it won't break your code and eat your TV dinners, though.
You need to ensure that you specify the library path during
linking when you compile your .c file:
gcc -I/usr/local/include xxx.c -o xxx -L/usr/local/lib -Wl,-R/usr/local/lib
The -Wl,-R part tells the resulting binary to also look for the library
in /usr/local/lib at runtime before trying to use the one in /usr/lib/.
Try adding LD_LIBRARY_PATH, which indicates search paths, to your ~/.bashrc file
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path_to_your_library
It works!
The linux.org reference page explains the mechanics, but doesn't explain any of the motivation behind it :-(
For that, see Sun Linker and Libraries Guide
In addition, note that "external versioning" is largely obsolete on Linux, because symbol versioning (a GNU extension) allows you to have multiple incompatible versions of the same function to be present in a single library. This extension allowed glibc to have the same external version: libc.so.6 for the last 10 years.
cd /home/<user_name>/
sudo vi .bash_profile
add these lines at the end
LD_LIBRARY_PATH=/usr/local/lib:<any other paths you want>
export LD_LIBRARY_PATH
Another possible solution depending on your situation.
If you know that libpthread_rt.so.1 is the same as libpthread_rt.so then you can create a symlink by:
ln -s /lib/libpthread_rt.so /lib/libpthread_rt.so.1
Then ls -l /lib should now show the symlink and what it points to.
I had a similar error and it didn't fix with giving LD_LIBRARY_PATH in ~/.bashrc .
What solved my issue is by adding .conf file and loading it.
Go to terminal an be in su.
gedit /etc/ld.so.conf.d/myapp.conf
Add your library path in this file and save.(eg: /usr/local/lib).
You must run the following command to activate path:
ldconfig
Verify Your New Library Path:
ldconfig -v | less
If this shows your library files, then you are good to go.
running:
sudo ldconfig
was enough to fix my issue.
I had this error when running my application with Eclipse CDT on Linux x86.
To fix this:
In Eclipse:
Run as -> Run configurations -> Environment
Set the path
LD_LIBRARY_PATH=/my_lib_directory_path
Wanted to add, if your libraries are in a non standard path, run ldconfig followed by the path.
For instance I had to run:
sudo ldconfig /opt/intel/oneapi/mkl/2021.2.0/lib/intel64
to make R compile against Intel MKL
All I had to do was run:
sudo apt-get install libfontconfig1
I was in the folder located at /usr/lib/x86_64-linux-gnu and it worked perfectly.
Try to install lib32z1:
sudo apt-get install lib32z1
If you are running your application on Microsoft Windows, the path to dynamic libraries (.dll) need to be defined in the PATH environment variable.
If you are running your application on UNIX, the path to your dynamic libraries (.so) need to be defined in the LD_LIBRARY_PATH environment variable.
The error occurs as the system cannot refer to the library file mentioned. Take the following steps:
Running locate libpthread_rt.so.1 will list the path of all the files with that name. Let's suppose a path is /home/user/loc.
Copy the path and run cd home/USERNAME. Replace USERNAME with the name of the current active user with which you want to run the file.
Run vi .bash_profile and at the end of the LD_LIBRARY_PATH parameter, just before ., add the line /lib://home/usr/loc:.. Save the file.
Close terminal and restart the application. It should run.
I got this error and I think its the same reason of yours
error while loading shared libraries: libnw.so: cannot open shared
object file: No such file or directory
Try this. Fix permissions on files:
cd /opt/Popcorn (or wherever it is)
chmod -R 555 * (755 if not ok)
I use Ubuntu 18.04
Installing the corresponding -dev package worked for me,
sudo apt install libgconf2-dev
Before installing the above package, I was getting the below error:
turtl: error while loading shared libraries: libgconf-2.so.4: cannot open shared object file: No such file or directory
I got this error and I think its the same reason of yours
error while loading shared libraries: libnw.so: cannot open shared object
file: No such file or directory
Try this. Fix permissions on files:
sudo su
cd /opt/Popcorn (or wherever it is)
chmod -R 555 * (755 if not ok)
chown -R root:root *
A similar problem can be found here.
I've tried the mentioned solution and it actually works.
The solutions in the previous questions may work. But the following is an easy way to fix it.
It works by reinstalling the package libwbclient
in fedora:
dnf reinstall libwbclient

I have installed GO, setup the paths but when i run a file i get this error:
error!! exec: "sqlboiler": executable file not found in $PATH
exec: "sqlboiler": executable file not found in $PATH
exec: "sqlboiler": executable file not found in $PATH
exit status 3
What is going wrong?
The installation instructions are good, https://go.dev/doc/install. However, for me un Ubuntu 20.4 in wsl2, the suggested path for the binaries wasn't enough. Only go and gofmt are added to /usr/local/go/bin.
I did add the below to my .bashrc, since go install puts the binaries in this location on my system.
export PATH="$HOME/go/bin:$PATH"
Note, that the path to the binaries may differ on your system, so you have to adjust it accordingly.
Any binary you install with go install that is added to this path will be available to your shell afterwards.
For example:
$ go install github.com/volatiletech/sqlboiler/v4#latest
$ go install github.com/volatiletech/sqlboiler/v4/drivers/sqlboiler-psql#latest
$ whereis sqlboiler
sqlboiler: /home/blue/go/bin/sqlboiler
Potentially, you also need some database packages to your system. I am not sure on this any more. For example, you could add some Postgres libs if you are using Postgres. You have to see if it works without.
apt-get install postgresql-client-common postgresql-client-12
How to properly install GO with paths and all?
Install Go with the installer (Windows) or archive (extract into /usr/local on Linux/Mac).
When installing from archive, manually add the directory path where the go binary is located (/usr/local/go) to PATH.
Set GOPATH to a directory path wherein to contain bin, pkg and src sub-directories.
Add ${GOPATH}/bin to PATH.
What is going wrong?
The program you are running is trying to run the executable sqlboiler, which cannot be found in any of the directories specified in PATH.
I'm trying to follow the instructions from Here.
The instructions seem very straight forward, but I can't get it to compile. If I download the gtest file from the website, it appears there are header files missing from the include directory which means they don't get into the gtest-framework.
the files are the gtest-port-arch.h and everything in the internal/custom folder. I get complier errors that these files are not found.
If I get the source from the svn, all of the files are present in the include dir of the sdk, however, the source folder in the xcode project omits the same files from being added to the project. I have to add them myself then build the frame work. The missing files are then present, but when I build the gtest-framework and add it to the test project, then the Test target's main class does not recognize the TEST calls and I get errors like C++ requires all types to be defined. I am following the steps. I really need to get this framework functioning.
Any help appreciated.
I had the same issue and couldn't find out the problem.
Ended up installing the libraries and simply linking them to Xcode, as described in the answer here
I copy the instructions here too. The only difference is that I used /usr/local/include and /usr/local/lib
Moreover, do not forget to set these for your "Tests" target:
Library search paths: /usr/local/lib
User header search paths: /usr/local/include
other linker flags: -lgtest
Copied:
1. Get the googletest framework
$ wget http://googletest.googlecode.com/files/gtest-1.7.0.zip
2. Unzip and build google test
$ unzip gtest-1.7.0.zip
$ cd gtest-1.7.0
$ ./configure
$ make
3. "Install" the headers and libs on your system.
$ sudo cp -a include/gtest /usr/include
$ sudo cp -a lib/.libs/* /usr/lib/
This question has been asked many time but I am not able to resolve the problem from them so I am asking
I had installed Cygwin a few days ago.I tried using ./configure command but it says
-bash: ./configure: No such file or directory
I tried using
where configure
but I got the output
INFO: Could not find files for the given pattern(s).
then I tried grep configureand I got this output
/etc/bash_completion.d/configure
/usr/i686-pc-cygwin/sys-root/usr/share/libtool/libltdl/configure
/usr/share/ELFIO/configure
/usr/share/libtool/libltdl/configure
I tried to export the path and then run the ./configure but it also didn't worked.
I find no executable file named as configure in my cygwin bin directory.
Does it mean that I have to add configure file manually?How can I correct it?
NOTE :- I had also tried sh configure but it also didn't worked
If a software project is set up to be built using autoconf, that tool generates a script canonically called configure. It queries the system for various parameters that are subsequently used in the build, and is specific to the software package to be built. Different software projects have different configure scripts. They are all called configure, but their contents are not the same.
So, to actually build such a software project once that script was set up (usually done by the maintainers when packaging the source tarball for distribution), you call:
tar xzf <tarball>.gz # or xjf <tarball>.bz2 or whatever
cd <sourcedir> # the one you just untarred
./configure
make
make install
Note the prefix ./, which means "located in this directory" (i.e. the top directory of that project's source tree).
Actually, the better procedure is the so-called "out-of-tree build", when you set up a different directory for the binaries to be built in, so the source tree remains unmodified:
tar xzf <tarball>.gz # or xjf <tarball>.bz2 or whatever
mkdir builddir
cd builddir
../<sourcedir>/configure
make
make install
So, there is supposed to be no configure executable in your PATH, you are supposed to call the script of that name from the source tree you are trying to build from.
If I correctly understood...
Configure is not an application that should be installed on your system, but script that should be delivered with source code to prepare for make command. File named configure should be in the main directory of source code.
I understand that this is an old question. However many might find this solution helpful.
Normally we use the make command to compile a downloaded source in cygwin. In many cases it contains a autogen.sh file. Running that file with
bash autogen.sh
will in many case solve the problem. At least it solved my issue and i could then use the make command
When I try running openFrameworks example audioOutputExample in CodeBlocks, I get the following errors:
in Debug:
ld cannot find -openframeworksDebug
in Release:
ld cannot find -openframeworks
How do I solve this?
UPDATES
Here is why I've tried up to now:
make
cd apps/examples/audioOutputExample/
make
[...]
compiling done
to launch the application
cd bin
./audioOutputExample
ok
cd bin
./audioOutputExample
./audioOutputExample: error while
loading shared libraries:
libfmodex.so: cannot open shared

[finds nothing]
ldconfig
ldconfig
/sbin/ldconfig.real: Can't create
temporary cache file
/etc/ld.so.cache~: Permission denied
sudo ldconfig
[Enter password]
[Finishes very quickly with no output whatsoever]
if you are on linux may this can help:
run this two scripts from /scripts/linux/ with root privileges:
./install_dependencies.sh
./install_codeblocks.sh
first look for the location of the libfmodex.so library. It should be in the libs path in the same directory as the application you try to start.
like this
someApp
libs/libfmodex.so
If this is not the case, copy it over there (should usually be done by make).
If still not ok use ldd.
ldd someApp
This will show you, where someApp looks for the missing library.
The following options are now available to you:
adjust LD_LIBRARY_PATH to include a directory, where your lib(.so files) is located
use ldconfig -l /path/to/lib/libfmodex.so
