More operating systems with GNU GPS

More operating systems with GNU GPS

[ldries46]

I have a running GPS system om my windows 10 system and several programs 
running there. Now I want these programs running on a Linux system. As Ada 
was designed as an operating system independent language The compiler should 
compile my sources also on Linux but I realize that the .gpr file cannot be 
used directly. My question is is there a simple way of converting a .gpr 
file from the one operating system to the other? I would prefere someprogram 
which would ask questions.

If properly written it can.

That depends on the kind of differences. Some differences can be 
factored out as values of project scenario variables. Others (external 
libraries) can be factored out as target system dependent projects you 
refer from the main project.

When you say 'GPS system' do you mean GNAT GPS or the Global Positioning
System?

I've never gone from developing a Windows GPR and moving it to Unix, but
the reverse has never caused me problems.

I _think_ that so long as you always use '/' as your directory
separator, _even on Windows_, you'll be OK.

Yes, as referenced in the title I meant GNAT GPS.
As I have my Windows system divided in several partitions to run a neat 
system and keeping it neat.
The GPS software and fi instance GtkAda are positioned in another partition 
as the ada source and build files.
This means that I do get references to several partitions and directories in 
my system. of course I can edit them all manually, but If it can be done 
with some program It would be less easy to make mistakes.

I see the problem.

Would aggregate projects[1] help?

No, it does not mean this. GtkAda comes with gtkada.gpr file which is 
system dependent. You "with" gtkada.gpr in you project and this is all 
you have to do. Your project remains independent on the target system.

I've never seen any major issues, but you can look through the Makefile, settings.gpr and the src/gnoga.gpr files in Gnoga to see examples of how to handle various builds across platforms and handle their differences.

I've had GPS running on an Ubuntu Linux box with the 2014 Linux package.
When I tried to install the system on the same box with the 2015 GPS
package, it looks like the Ubuntu update process was missing some libraries.
I've been too loaded with other work to track down the problem.  However,
I expect that with some care you should be able to install on a Linux
system and not notice many differences.  The usual care that goes with 
that is of course to be expected.  

I can't say anything about the gtk libraries.  Most of my work has been
dealing with either fairly straightforward numerical computations or
html (Web) stuff.  I haven't had time to resolve what I need to do to
deal with AWS or PolyORB.
