Please include more details in your report such as the PLplot version
currently not working for you; its provenance (e.g., is it from an
installed Ubuntu package, a version you built and installed yourself,
etc.); exact details of the build of your x16c application (e.g.,
expand $1 and $FirstOfile above, and give the generated executable
name); and exactly how you ran (e.g., include all command-line
options) that built executable.  Also, what version (and provenance)
of PLplot worked for you before?

Note, if there is some PLplot packaging error with Ubuntu we cannot
help you very much.  However, we can help you if you build and install
Plplot yourself from either the latest release (5.15.0) or ideally the
git master tip version.  For example, such installs include C examples
(such as x16c) that are all ready to build using pkg-config, and also
include tests of such pkg-config-based builds.

N.B. we continue to maintain our installed pkg-config-based build and
test system for our standard examples, and if you have found a bug in
that, we will fix it.  However, that build and test system is quite
low power and therefore we recommend instead our high-power
CMake-based build and test system for our installed examples.  See
<https://sourceforge.net/p/plplot/wiki/Testing_PLplot/> for further
details about our various test systems.

Cheers,

Alan
