I have a program using unit
fpcgraph ptcgraph. It was working with an older version of freepascal, but now with version 3.0.2 of fpc, I get this error while compiling:
Free Pascal Compiler version 3.0.2+dfsg-2 [2017/04/09] for x86_64
Copyright (c) 1993-2017 by Florian Klaempfl and others

Compiling hypercub.pas
Compiling ptcgraph.pp
Fatal: Can't find unit syncobjs used by ptcwrapper
Fatal: Compilation aborted
Error: /usr/bin/ppcx64 returned an error exitcode
ptcwrapper is referencing unit syncobjs, but this unit is not compiled.
The problem was that package fp-units-fcl-3.0.2 was not installed.
