What is the difference between libgfortran.3 and libgfortran? Are they interchangeable? I am running into a Internal Error: list_formatted_write(): Bad type error including a packaged libgfortran.3 library, and I want to be aware of the potential consequences of switching to gcc's libgfortran.

There should be no difference, and for typical installations both of those files are symlinks to the actual library, e.g. libgfortran.so.3.0.0. 

/usr/lib64/gcc/x86_64-pc-linux-gnu/5.1.0/libgfortran.so -> libgfortran.so.3.0.0*
/usr/lib64/gcc/x86_64-pc-linux-gnu/5.1.0/libgfortran.so.3 -> libgfortran.so.3.0.0*
/usr/lib64/gcc/x86_64-pc-linux-gnu/5.1.0/libgfortran.so.3.0.0*

The only differences you might encounter are if you are using a libgfortran that doesn't match your gfortran version, but in theory they should all be api compatible since they carry same shared object version.

  • Why do these different names even exist? – kilojoules Jul 10 '15 at 22:20

    @kilojoules Some libraries will have multiple versions installed side by side. The naming lets you choose to link the default version, a specific major version or a specific subversioned library. This is the typical way all libraries on linux are handled. – casey Jul 10 '15 at 23:55
