PB: using gnatlink to link C and ADA code

PB: using gnatlink to link C and ADA code

[Erik Herzog]

We have used GNAT for a number of years in a lab setup on solaris.
Except for some minor problems everything has worked fine unitl we 
upgraded to gnat 3.12.

The problem occur when gnatlink is used to link C and ADA code to the
final
application. Gnatlink reports it 'failed to open the binder output'

The link sequence is shown below.

Any ideas where the problem could be?

Perhaps your makefile has to be changed because the "gnatbind" creates
an Ada main program by default in GNAT version 3.12?

Hello Erik!

I don't know where the problem is but if you do the following it should
work (it did for me anyway):

gedrix.ida.liu.se:BANKER> which gnatlink
/sw/gnat-3.12/bin/gnatlink
gedrix.ida.liu.se:BANKER> \rm *.ali
gedrix.ida.liu.se:BANKER> gnatmake -c td_ada
gcc -c td_ada.adb
gcc -c thread_ada.adb
gcc -c types.adb
types.adb:16:25: warning: type of "Strcpy.Src" does not correspond to C
pointer
gedrix.ida.liu.se:BANKER> make
gcc -c -g -I/home/x98gusth/BANKER bankers_alg.adb
gnatbind -n /home/x98gusth/BANKER/td_ada.ali
/home/x98gusth/BANKER/types.ali \
            /home/x98gusth/BANKER/thread_ada.ali bankers_alg.ali
gnatlink  -lthread -lsocket -lnsl -o .rw /home/x98gusth/BANKER/thread.o
/home/x98gusth/BANKER/message.o /home/x98gusth/BANKER/lowlevel_io.o

/home/x98gusth/BANKER/bankerIO.o /home/x98gusth/BANKER/main.o -D_REENTRANT
bankers_alg.ali

Program 'banker' compiled.


To run with a simulator, start with 'banker <number>'
where <number> in range 2000..32000.

You can find the compiled version in /home/x98gusth/BANKER
