Summary:

Doesn't build on Mac OS X

Description:

On Apple's unix-porting list, Marco Baroni (baroni@sslmit.unibo.it) reported that libcfg+-0.6.2 didn't compile on Mac OS X. I was curious, so I took a look and fixed it, albeit not in a way that'll work with your autoconf setup. That'll take a little bit of tweaking.

Steps To Reproduce:

On Mac OS X, grab the code and run ./configure && make. You'll see this:

ld -shared -o libcfg+.so.0.6.2 ../src/cfg+.o ../src/parse.o ../src/props.o ../src/cmdline.o ../src/cfgfile.o ../src/shared.o ../src/platon/str/strplus.o ../src/platon/str/strctype.o ../src/platon/str/strdyn.o ../src/platon/str/dynfgets.o
ld: unknown flag: -shared
make[1]: *** [libcfg+.so.0.6.2] Error 1
make: *** [all-src] Error 2

Additional Information / Solution:

There are two problems:
1) Mac OS X uses '.dylib' as its shared library extension, not '.so'.
2) Mac OS X's ld doesn't understand '-shared'. You need to use '-dylib', but that introduces some other complications so it's easier to link with gcc and use '-dynamiclib'.

Here are my diffs. I think the change from $(LD) to $(CC) should be portable, but the use of the -dynamiclib flag and the reworking of the library extension will have to be autoconf'd.
