Please see also the latest alternative with local fpc.cfg conf files to
set up the namespaces....

I like your "packages" idea, it sounds similar to Lazarus Packages (*.lpk),
but without the Lazarus IDE requirement. I currently use Lazarus Packages
support for managing fpGUI based applications, and would like to see if
your idea could fit in with fpGUI too (without needing Lazarus IDE
support). The problem I see, is that your "alias/package" only seems to
take one directory location for source code (*.pas). For fpGUI, I have a
directory hierarchy for the fpGUI sources.
....
I can't see your idea working for compiling a fpGUI based application
directly from source. But I can see your idea work for projects using the
pre-compiled fpGUI units ('lib' directory with *.ppu files), because the
latter is only one path. Whereas the sources are multiple source paths and
multiple include paths. Am I correct?
I can only use: -Fl=FPGUI:~/programming/fpgui/lib/i386-linux
but can't use -Fu or -Fi: -Fu=FPGUI:~/programming/fpgui/src
because the latter doesn't include all the unit and include paths required
for fpGUI.
The above is obviously possible with Lazarus Packages, because I can
specify multiple search paths in the *.lpk compiler configuration dialog.
It shouldn't depend on lpk files.
the lpk files are only for lazarus, the compiler doesn't see them. Any
info in them is translated by lazarus for fpc.
For your case, it would simply be necessary to specify the same
namespace for multiply -Fu => and as a result expect all of them to be
in this namespace
-FuFPGUI:.
-FuFPGUI:corelib/
#IFDEF X11
-FuFPGUI:corelib/x11/
#ENDIF
#IFDEF GDI
-FuFPGUI:corelib/gdi/
#ENDIF
-FuFPGUI:gui/
-FuFPGUI:gui/db/
The only problem with this is, that it wouldn't detect any other package using
this namespace => no reflict would be reported, but instead the namespaces be
merged
-FuFPGUI:/path/to/mfr/package
alternatively (either in-Fu or in local fpc.cfg) =< the namespace can be
specified in a separate instruction, specifing that it applies recursive to
subdirectories.
having all your directories in -Fu you would do
-FNFPGUI:/path/to/fpguibase/*
the asterisk specifies => recursive
