Re: PB: using gnatlink to link C and ADA code

[Gustaf Thorslund <gustaf@thorslund.org>]

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/output_control.o /home/x98gusth/BANKER/rwADT.o
/home/x98gusth/BANKER/td.o /home/x98gusth/BANKER/event_read.o
/home/x98gusth/BANKER/atc.o /home/x98gusth/BANKER/train.o
/home/x98gusth/BANKER/socketCom.o /home/x98gusth/BANKER/catch_disaster.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.
gedrix.ida.liu.se:BANKER>

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