[SOLVED] How do I get a Judy Array example to compile correctly?

How do I get a Judy Array example to compile correctly?

I am attempting to compile the example given at http://judy.sourceforge.net/doc/JudySL_3x.htm#JSLG. I have downloaded, configure'd, make'd, and sudo make install'd the Judy library as per the distribution. However, when I compile (GCC on a Mac), I receive the following errors:

Undefined symbols:
"_JudySLFreeArray", referenced from:
    _main in ccziTK43.o
"_JudySLNext", referenced from:
    _main in ccziTK43.o
"_JudySLIns", referenced from:
    _main in ccziTK43.o
"_JudySLFirst", referenced from:
    _main in ccziTK43.o
ld: symbol(s) not found
collect2: ld returned 1 exit status

Can Anyone point Me in the direction of information on how to resolve this? (Just for the record, the file being compiled is a C module, yes.)

Also, My command is simply gcc test.c.

Solution

You need to tell gcc to link against the Judy library, using the -l option -- e.g.

gcc -lJudy test.c
