How to link to ada-util

[Alain De Vos]

The ada-util package has many interesting features.
https://github.com/stcarrez/ada-util
How I use it.
I copy my application to the samples directory and run the gnatmake -Psamples which uses samples.gpr.
I have not find a better way to link to ada-util.
Is there a better easier way ?

When I try a simple gnat make test.adb on a file containing :
with Util.Streams.Pipes;
I get the error "util.ads" not found.
I think I need to tell the systeem where to look for all necessary .ads files, which are in a tree ...

Ada-Util has dependencies upon other github repositories and it is part of the AWA framework. To be able to use Ada-Util I recommend going to
https://github.com/stcarrez/ada-awa
and follow the instructions there:
   git clone git@github.com:stcarrez/ada-awa.git
   cd ada-awa
   git submodule init
   git submodule update

Best regards,
Joakim

Here is how i tried to compile and bind and this worked on my program :
gcc -c    -I/usr/local/include/utilada_core.static -I/usr/local/include/utilada_sys.static -I/usr/local/include/utilada_base.static mystuff.adb 
gnatbind  -I/usr/local/lib/utilada_core.static     -I/usr/local/lib/utilada_sys.static   -I/usr/local/lib/utilada_base.static mystuff
But I failed gnatlink to provide the good parameters.... so I'm stuck.
In fact I want to know what I'm doing.
And don't need to link to every library available.

Always use project files, never makefiles. If the library provider does 
not give you a project file, ask him to do it. If he refuses to, write 
your own project file. You can do it for system and non-Ada libraries 
too. You must learn to do this if you want to use GNAT.

I have to agree, make really isn't as portable* as many linux-types want to make you believe; and that's in addition to being rather fragile.

* Try using Borland's make utility on their makefiles.

Don't you need two project files.
A project file when the package exists as sources in the subtree.
A project file when the package is installed.
