[help-GIFT] Installing GIFT on Mac OS 10.4.7 - issues, and some fixes

[David Squire]

Issues:

- ./configure succeeded, but makes fails because expat.h can't be found. 
I have installed expat using DarwinPorts, so it is found in 
/opt/local/include/. I added this to DEFAULT_INCLUDES in Makefiles in 
libMRML/cc/, libGIFTAcURL2FTS/cc/, and libGIFTAcHierarchy/cc/, 
GIFTServer, . This fixed the problem. Should ./configure be checking for 
expat.h?

- Mac OS X does not have malloc.h. malloc() is defined in stdlib.h. I 
removed "#include <malloc.h>" from *.c in libSquirePPM/, and ensured 
that all had "include <stdlib.h". I seem to recall that when building on 
my AMD 64 machine under Ubuntu I had to ensure that malloc.h *was* 
included, so perhaps we need conditional includes here.

- Mac OS X does not have values.h. This causes a problem for 
libSquirePPM/ppm_normalize.c, which uses it for MAXFLOAT. Solution? Just 
remove the line, as it is defined in math.h.

- Sockets. And now we run into the first problem that I can't do a quick 
fix for:

if g++ -DHAVE_CONFIG_H -I. -I. -I.. -I/opt/local/include 
-I../libMRML/include -I../libGIFTAcInvertedFile/include 
-I../libGIFTAcURL2FTS/include -I.   -I.    -g -O2 -DEF_PROTECT_BELOW=1 
-DEF_PROTECT_FREE -DEF_PROTECT_ALIGNMENT=8 -DEF_FILL=42  -MT 
CDomainSocket.o -MD -MP -MF ".deps/CDomainSocket.Tpo" -c -o 
CDomainSocket.o CDomainSocket.cc; \
then mv -f ".deps/CDomainSocket.Tpo" ".deps/CDomainSocket.Po"; else rm 
-f ".deps/CDomainSocket.Tpo"; exit 1; fi
CDomainSocket.cc: In member function 'virtual bool 
CDomainSocket::acceptAndServe()':
CDomainSocket.cc:98: error: aggregate 'ucred lCredentials' has 
incomplete type and cannot be defined
CDomainSocket.cc:102: error: 'SO_PEERCRED' was not declared in this scope
make[3]: *** [CDomainSocket.o] Error 1

It seems that BSD (on which Darwin is built) and Linux handle this stuff 
differently. See for example 
http://archives.postgresql.org/pgsql-patches/2002-12/msg00015.php

If someone has experience of getting this to work on BSD systems, leap 
in now :) Otherwise I will start digging and see what I can find out.

Regards,

David
