problems with make

[Thomas L. Scofield]

I finally was able to compile the latest repository on my mac about a couple of weeks ago for the first time.  It is on that machine I would like to carry out continued development.  The crucial step was the following arguments to configure (which, I have no doubts, are not optimized):

./configure CPPFLAGS="-I/sw/include -I/Developer/SDKs/MacOSX10.4u.sdk/usr/X11R6/include" LDFLAGS="-L/sw/lib/ -L/usr/lib -L/Developer/SDKs/MacOSX10.4u.sdk/usr/X11R6/lib" --prefix=/sw

This command worked insofar as the only complaint about libraries I received at the end was that "FLTK backend libs" were not found, nor were the ones "necessary to compile native graphics."  I think that this was during the time between John Eaton's changeset to imread.m and __magick_read__.cc (July 16, changesets 8123 and 8118?) and today, for I was successfully using imread.m from core Octave.  I tried the same configure command today after downloading the most recent repository, and it seemed to work even better---I still see the "didn't find the necessary libraries ..." warning, but now it is finding viable "FLTK backend libs".  Issuing "make" last week was successful, and I had a working program.  Today, make fails; here are the last few lines of output:

./DLD-FUNCTIONS/__magick_read__.cc: In function 'octave_value_list read_indexed_images(std::vector<Magick::Image, std::allocator<Magick::Image> >&, const Array<octave_idx_type>&, bool)':

make[2]: *** [pic/__magick_read__.o] Error 1

make[1]: *** [src] Error 2

make: *** [all] Error 2

As best as I can tell, this compile problem seems to have arisen with the addition of __magick_write__.  Any ideas?
