I have been doing some work on imread(). I'm not well-versed in the
compiling/linking process, and have had trouble with this on my Mac.
I have the image-1.0.6 package on my mac and can use it. What I
cannot do is make changes to a file like __magick_read__.cc and then
compile it on the Mac. It's not my changes which are at fault. For
the last few weeks I've been using a linux machine instead, where
I've got things setup correctly (I guess), and I can run something like
mkoctfile __magick_read__.cc `Magick++-config --cppflags` -lMagick
++ -lMagick
without an error. (My changes, which involve an effort to move away
from ImageMagick and towards GraphicsMagick, compile, and the routine
is usable on that machine.) But on the Mac I get all kinds of
"undefined symbol" messages from ld (see below). I'm guessing this
problem stems from looking for libraries (and perhaps header files)
in the wrong places. (I do not know which libraries these symbols
come from.) I hardcoded the locations of "oct.h" and "Magick++.h"
into __magick_read__.cc, (i.e., changed #include octave/oct.h to
#include /sw/include/octave3.0.0/octave/oct.h), but that had no
effect. I recently got GraphicsMagick to compile from source on this
machine by doing
ln -s /sw /Developer/SDKs/MacOSX10.4u.sdk/sw
./configure CFLAGS="-O -g -isysroot /Developer/SDKs/
MacOSX10.4u.sdk/ -arch i386 -I/sw/include/" LDFLAGS="-Wl,-syslibroot,/
Developer/SDKs/MacOSX10.4u.sdk/,-L/sw/lib/" --prefix=/sw --with-
quantum-depth=16 --disable-dependency-tracking --with-x=yes --x-
includes=/usr/X11R6/include --x-libraries=/usr/X11R6/lib/ --without-perl
This was a modification of the instructions someone had supplied for
compiling GraphicsMagick on a Mac (and probably reveals how little I
know about what I'm doing). Nevertheless, even if I fully understood
what I did above, it is not clear to me how these options fed to a
configure script translate into options fed to mkoctfile.
Can anyone who uses a Mac help me get through this compile?
