In this article, we’ll be discussing how to fix the “libusb-0.1.so.4” shared library error in Ubuntu 64-bit system. This error typically arises when an executable file is unable to find the required shared library, causing the program to fail. We’ll be providing a detailed guide on how to resolve this issue.
To fix the "libusb-0.1.so.4" shared library error in Ubuntu 64-bit system, you need to enable MultiArch support, update the package lists, and install the 32-bit version of the libusb-0.1-4 library. If that doesn’t work, you can try installing the libusb-dev package instead.
Understanding the Error
Before we dive into the solution, let’s understand what this error means. The “libusb-0.1.so.4” is a shared library file that certain programs need to run correctly. If this file is missing or inaccessible, the program will not be able to execute, resulting in the error message.
Enabling MultiArch Support
The first step in resolving this error is to ensure that your Ubuntu system has MultiArch support enabled. MultiArch allows you to install 32-bit libraries on a 64-bit system, which is necessary to fix this error.
You can check if MultiArch is enabled by looking for
foreign-architecture i386 in the file
To do this, use the command:
foreign-architecture i386 is not present in the output, you’ll need to enable MultiArch. Run the following command:
echo "foreign-architecture i386" | sudo tee /etc/dpkg/dpkg.cfg.d/multiarch
In this command,
echo "foreign-architecture i386" creates a string that is then added to the file
/etc/dpkg/dpkg.cfg.d/multiarch using the
tee command. The
sudo command is required to execute this as the root user, as normal users do not have write access to this file.
Updating the Package Lists
After enabling MultiArch, you should update your package lists to ensure that your system has the latest information about available packages. You can do this by running:
sudo apt-get update
sudo apt-get update command fetches the package lists from the repositories and “updates” them to get information on the newest versions of packages and their dependencies.
Installing the Required Library
Now that your system is ready, you can install the 32-bit version of the
libusb-0.1-4 library. This can be done with the following command:
sudo apt-get install libusb-0.1-4:i386
In this command,
sudo apt-get install is used to install new packages, and
libusb-0.1-4:i386 specifies the 32-bit version of the
Alternative Solution: Installing the libusb-dev Package
If the above steps do not resolve the error, or if the 32-bit version of
libusb-0.1-4 is not available in your package manager, you can try installing the
libusb-dev package instead. This package contains files necessary for building applications that use libusb.
You can install it by running:
sudo apt-get install libusb-dev
By following these steps, you should be able to resolve the “libusb-0.1.so.4” shared library error in Ubuntu 64-bit system. Note that these solutions are specific to Ubuntu 12.04, and if you are using a different version of Ubuntu, the package names or steps may vary. If you encounter any issues, feel free to consult the Ubuntu community for further assistance.
A shared library error occurs when an executable file is unable to find a required shared library, causing the program to fail. Shared libraries are files that contain code and resources that can be used by multiple programs, allowing for code reuse and efficient memory usage.
The "libusb-0.1.so.4" shared library error occurs when the program is unable to locate the "libusb-0.1.so.4" shared library file. This can happen if the file is missing, inaccessible, or if the program is looking in the wrong location for the library.
You can check if MultiArch support is enabled by running the command
cat /etc/dpkg/dpkg.cfg.d/multiarch in the terminal. If the output includes the line
foreign-architecture i386, then MultiArch support is enabled. If this line is not present, you’ll need to enable MultiArch using the command
echo "foreign-architecture i386" | sudo tee /etc/dpkg/dpkg.cfg.d/multiarch.
sudo apt-get update command fetches the package lists from the repositories and updates them to get information on the newest versions of packages and their dependencies. This ensures that your system has the latest information about available packages.
To install the required library, you can use the command
sudo apt-get install libusb-0.1-4:i386. This command installs the 32-bit version of the
libusb-0.1-4 library, which is necessary to fix the error.
