Installing GtkAda on Linux (Ubuntu)

Installing GtkAda on Linux (Ubuntu)

[ldries46]

I am trying to install Gtkada on Linux beside my installation on Windows 10.
I thought the installation was correct but trying to load an on Windows 
running project the GNAT Prgramming Studio could not find gtkada.gpr  
despite of the fact that The PATH variable included the directory where 
the project file is located. Also ADA_INCLUDE_PATH and ADA_OBJECTS_PATH 
point to that directory the file and the directories have protection 
which allow the file to be used. What do I have forgotten?

You forgot:

1. Read and memorize Debian policy for Ada

    https://people.debian.org/~lbrenta/debian-ada-policy.html

Either

2. Install libgtkada19-dev, if I correctly name the package as it is 
kind of ever changing thing in Debian/Ubuntu.

or

2. Download the latest GtkAda sources

3. Compile and build GtkAda from the sources

4. Install the built GtkAda exactly as #1 requires

You need to use ADA_PROJECT_PATH or GPR_PROJECT_PATH

I already had Gtkada installed but only something simple as "with 
gtkada;" in the .gpr file does not work. IIn the mean time I have tried 
also to put the specific directory in the environment variables 
ADA_PROJECT_PATH and GPR_PROJECT_PATH yjat also didn't work. The latest 
version which is used in the link is from 2014
Your link  did not have any link to the mentioned "with" in the .gpr file

I already used the latest version of the Adacompiler and Gtkada (both 
2020 version from Adacore for as well GNAT community as Gtkada)

Installs done with the install script which also compiles the sources

You do not need any environment variables. Provided you use the FSF 
compiler. That is the idea of having language policies. Everything works 
out of the box.

OK, this is a completely different scenario. Do you use AdaCore's 
compiler instead of the FSF compiler? [Why?] You will have 
ADA_PROJECT_PATH, LIBRARY_PATH correctly set. I wonder if AdaCore 
installer sets them already and you must move them into your .bashrc or 
whatever. To check yourself use -I switches with grpbuild. You can 
always add paths explicitly from the command line.

Look if GtkAda's bin directory has gtkada-config executable. It returns 
switches for compiling/building GtkAda applications. Add them to the 
gprbuild's command line.
