Stumbled by the docker error while loading shared libraries? We can help you with fixing it.

Usually, this error occurs while building a docker image.

Here at Bobcares, we have seen several such Docker-related errors as part of our Docker Hosting Support for Docker users, web hosts, and online service providers.

Today we’ll take a look at the cause for this error message and see how to fix it.

How we fix the error ‘Docker error while loading shared libraries’

Now let’s see the suggestions our Support Engineers provide our customers to resolve this error.

One of our customers came across this error message while building a docker image. He was using the COPY command to copy a local file from the host into my container.

After building the image, he ran an interactive shell to test the file.

Also, he placed a “software” directory under the Dockerfile directory which has XYZ executable. But after entering the container built by the image and running the executable, he ran into the below error message:

root@server:/bin# ./xyz ./xyz: error while loading shared libraries: libxyz.so.3: cannot open shared object file: No such file or directory

One checking, we found that here, the error tells that the customer has copied over the executable, but it has dependencies on various libraries (including libxyz.so.3) that aren’t in the container.

So, we suggested the below to resolve this error message.

Add the dependencies to the container. By running ldd tool on executable, we can find which dependencies it requires. Either can copy the libraries directly into the container as done with the executable. Or find which package the dependencies are from and install with apt-get.

Or

recompile the executable so that it is statically linked.
