Mattias,

dpkg -l | grep fpc
ii  fpc 3.0.0+dfsg-2                                 all          Free 
Pascal - SDK suite dependency package
ii  fpc-3.0.0 3.0.0+dfsg-2                                 all          
Free Pascal - SDK-3.0.0 suite
ii  fpc-source 3.0.0+dfsg-2                                 all          
Free Pascal - SDK source code dependency package
ii  fpc-source-3.0.0 3.0.0+dfsg-2                                 
all          Free Pascal - SDK source code

This is consistent with:

fpc -v
Free Pascal Compiler version 3.0.0+dfsg-2 [2016/01/28] for x86_64
Copyright (c) 1993-2015 by Florian Klaempfl and others
Fatal: No source file name in command line
Fatal: Compilation aborted
Error: /usr/bin/ppcx64 returned an error exitcode

Then:

sudo dpkg -i fpc_3.0.4-rc1_amd64.deb
dpkg: regarding fpc_3.0.4-rc1_amd64.deb containing fpc:
  fpc conflicts with fpc
   fpc-3.0.0 provides fpc and is present and installed.

dpkg: error processing archive fpc_3.0.4-rc1_amd64.deb (--install):
  conflicting packages - not installing fpc
Errors were encountered while processing:
  fpc_3.0.4-rc1_amd64.deb

Unfortunately the gui installer did NOT produce any error messages so I 
was misled into thinking that it was successful.

This gives me enough information that I can continue.  I'll keep you 
informed of my progress.

Thanks,

Don
