Build hints for Mac OS X with MacPorts + candidate fix to DINO/Makefile.am

[teshields]

Environment: Mac OS X El Capitan version 10.11.5 (current) Xcode version 7.3.1 (current) MacPorts version 2.3.4 (current) - provides libgmp

Build hints for this environment

MacPorts installs by default into '/opt/local/include' & '/opt/local/lib', so these paths need to be specified as part of the invocation of './configure'. In my particular environment, the MacPorts version of 'libiconv' is installed as a dependency for some other MacPorts package, and the MacPorts version of 'iconv.h' contains some unexplained weirdness that redefines 'iconv_close' as 'libiconv_close' causing unresolved symbol at dynamic load time. Fortunately, there is a compile-time symbol 'LIBICONV_PLUG' that will remove this particular bit of weirdness if defined at compile-time.

Hence, the following options to './configure' are needed In order to successfully configure the DINO distribution in my environment: ./configure CPPFLAGS="-DLIBICONV_PLUG -I/opt/local/include" LDFLAGS="-L/opt/local/lib"

A MacPorts environment without the MacPorts version of 'libiconv' wouldn't need '-DLIBICONV_PLUG'.

Candidate fix for DINO/Makefile.am

Because 'gmp.h' is installed in '/opt/local/include', the Makefile rule to build 'd_genheader.i' in 'DINO/Makefile.am' in the dino-20160402 distribution doesn't find 'gmp.h' because the 'CPPFLAGS' variable isn't included in the compile command argument list.

This may not be the perfect fix, but adding '$(CPPFLAGS)' on line 86 (below) in 'DINO/Makefile.am' works for me: $(CC) @DEFS@ -I$(srcdir) -I. $(CPPFLAGS) $(libdino_la_CFLAGS) $(CFLAGS) -E > d_gen.tmp $(srcdir)/d_gen.c && mv d_gen.tmp $@

Honestly, I did not think about MacPorts. Thank you for pointing the problem out. I'll incorporate your solution and document it.

I've added CPPFLAGS to the Makefile rule and described what configure options to use to build Dino on Macports.
