Re: Link C main with Ada static library

I have lost my 3.14p docs and have only just installed 3.15p,
but it seems that the gnatbind "-L" switch is new (undoubtdly
wrong, but I hadn't noticed "-L" for gnstbind before).

... but (following from previous example) ...

-- main.c
extern int return_forty_two ();
extern int mylibinit ();
extern int mylibfinal ();

#include <stdio.h>

int main () {

     int i = 0;

     printf ("i => %d\n", i);

     mylibinit ();

     i = return_forty_two ();

     mylibfinal ();

     printf ("i => %d\n", i);

};

... the build ...

# gnatmake static_ada_library
# gnatbind -Lmylib static_ada_library
# gcc -c b~static_ada_library.adb
# ar cr libmylib.a b~static_ada_library.o static_ada_library.o
# gcc main.c -o c-test -lmylib -L. \
usr/gnat/lib/gcc-lib/i686-pc-linux-gnu/2.8.1/adalib/libgnat.a
# ./c-test
i => 0
i => 42
