I have a PC with Caldera Open Linux 2.3. I have just installed it, and
I'm new to
Linux. But I would like the Gnat Ada 95 compiler to run on it. This
little test
program should be OK, but look at the linker error below.

I have set the ADA_OBJECTS_PATH and ADA_INCLUDE_PATH according to the
doconfig
installation script, but this is perhaps not neccessary when I installed
it to
standard locations. The adalib directory referenced by gnatlink contains
only ali-
files and no .o files. Is this correct?

On my NT, Windows 95 and Solaris 2.4 Gnat 3.11 works fine.

By the way!. I had also trouble compiling a simple C++ program.
Compiling with gcc
gave me a program which only return "segmentation fault". But the
command g++ compiled
a program which was OK. Is g++ another program, and is this gcc problem
connected to
the Ada problem.

Help on this would be very helpful. Thanks!.
