That sounds good -- you must therefore have a working version of
mwrank (and what else would anyone need?) Sriously, this really
does
mean that the few binaries which eclib builds work OK.
Not that I had any doubts! But the problem is that somehow the
linking isn't happening properly in sage/libs/mwrank, and indeed
-lflint isn't in the line
g++ -bundle -undefined dynamic_lookup
-L/Users/student/Desktop/sage-6.2.beta4/local/lib
build/temp.macosx-10.4-ppc-2.7/sage/libs/mwrank/mwrank.o
build/temp.macosx-10.4-ppc-2.7/sage/libs/mwrank/wrap.o
-L/Users/student/Desktop/sage-6.2.beta4/local/lib -lcsage -lec -lntl
-lpari -lgmp -lgmpxx -lstdc++ -lm -lstdc++ -lntl -o
build/lib.macosx-10.4-ppc-2.7/sage/libs/mwrank/mwrank.so
Maybe could I add something to src/module_list.py or whatever the
appropriate file is now to force -lflint as well? On Cygwin we
often had to be more explicit because of something analogous, if I
recall that correctly. I'm going to try this just to see...
It seems to work! At least, things continue compiling. On Cygwin
that was always the sign of victory, though :)
Indeed, all of sage.libs.cremona needed this addition to the
module_list.py as well. I don't see how this hurts, so I'm probably
going to suggest this on the
ticket http://trac.sagemath.org/ticket/16017 - John, any thoughts? (Or
Leif or JP?)
Well, since it is illogical ;-) , we should make the addition
platform-dependent (apparently MacOS X 10.4 / Darwin 8 only, not Darwin
in general, and presumably Cygwin as well).
But someone familiar with flat vs. two-level namespace etc. can probably
tell better. (Adding or dropping some option on Darwin 8 might be
sufficient as well.)
Still puzzled by the original "file not found" linker

... and then, why does the linker bail out despite '-undefined
dynamic_lookup'? Why '-bundle' instead of '-dy[namic]lib'?
