Runtime evironment from gnat3.12p to gnat3.14 (Linux)

Runtime evironment from gnat3.12p to gnat3.14 (Linux)

[Mahesh Patel]

I have a question about Linux (Mandrake 7.1) and GNAT Ada (3.12p 
to 3.14).  I took over a application which was compiled with the 
gnat3.14 development environment.  They had a process in which 
they sent just the Ada application executables to the customer 
who had a PC with Mandrake 7.1 and the appropriate shared 
objects (from gnat3.12p) necessary to run the Ada application.  
The customer's environment was just an execution environment (no 
development libraries are on the machine).  I found out that they 
had the shared objects from gnat3.12p and the Ada application built 
with gnat3.14 will not execute.

My question after researching it on the Web - are the following 
files the only shared objects (/usr/lib) required to execute an 
Ada executable built with gnat3.14:

        libflorist-3.13p.so.1.7
	libgnarl-3.14.so
	libgnat-3.14.so

Thanks for your help in advance.

No. I am almost certain that you have to have the same 
version of the runtime libraries as of the compiler itself, 
to make a program run.

If your users are too lazy to install the apropriate runtime 
libraries, you can solve the problem by linking them 
statically to your program (have a look at what the 
arguments "-bargs -static" do to `gnatmake`).

Use

  $ ldd your-program

to see what shared libraries your-program needs.
