C libraries in Mac version

[William McCune]

I fetched gprolog-1.2.16.tar.gz and compiled and installed
it on a Mac (Panther), using the default configurations.
It seems to work consulting and compiling ordinary Prolog programs.

However, I have a problem linking C code that calls library functions.
I have narrowed it down to the following vacuous example, which
shows the problem.

    % touch empty_test.pl
    % gplc empty_test.pl -L -lcurl
    % ./empty_test 
    bus error

Notes:

   1. The curl library is not used in this example, and the same
      problem occurs with other libraries, e.g., -lm or -lssl.
   2. This example works correctly if I omit '-L -lcurl'.
   3. This example works correctly with the Linux binary RPM.

Thanks for any help you can give.

  Bill
