Cannot use Swift on Ubuntu 18.04

After conscientiously following the install instructions on Linux from swift.org, I encounter an issue where it is not possible to compile anything on a Ubuntu 18.04 machine. The REPL seems to work but during compilation (when calling swift build) the following error appears:

/usr/bin/ld: cannot find -lstdc++

There are more details in the full bug report [SR-9093]. I don't know at all what to do to solve this issue, there are similar problems already mentioned in other bug reports, for instance on this really old one [SR-35].

What should I do?

It seems possible that the apt install did not run the ldconfig program, which should be run to add the library to the list of those which ld.so knows about.

It looks like you can do it manually: sudo ldconfig

IMPORTANT CAVEAT: I don't have Ubuntu and haven't been able to test this. And it's a sudo command. Run at your own risk, YMMV, etc.

If this does not work, it's possible that a file called /etc/ld.so.conf is not set up to search the directory where libstdc++ ended up. I wouldn't dare try to describe how to fix that.

sudo apt install -f

The command above should install any missing dependencies.

I am assuming that you had already installed the libstdc++ successfully and you have set the permissions properly. But I really doubt that it was installed correctly but it was installed with corruption of some sort. The corruption occurred because you didn't install libstdc++ via a package manager. Result was some form of weirdness in the package manager database which effected the overall functioning system. Exactly why adding something to a folder should change anything at all. I don't know why this happens, unless the folder is hot i.e symbolically linked to a program which doesn't have any tolerance for hacks like simply copying a file into the folder. So for now try to install the libstdc++ again. Below is the link to the file to again download the correct program and this is compatible with amd64.

http://security.ubuntu.com/ubuntu/pool/main/g/gcc-5/libstdc++6_5.4.0-6ubuntu1~16.04.10_amd64.deb

And below are some link to help
