hi
i'm having a problem when compiling a c code (called geometry) invoking pgplot
libraries.
this code used to work fine in the past on my mac book (2.4GHz intel core2 duo)
under OSX 10.6.8
but is failing now for a reason that i cannot manage to work out
(i haven't tried it for a while so it may be related to an fink upgrade that
occured a few months ago).
this very same code is working fine on my mac pro (same version of OSX, latest
version of fink stable)
but is apparently failing on the macbook.
here is the message i'm getting : obviously, it's having trouble finding a
routine,
that should presumably be part of libpng but is not (since i'm linking with
libpng obviously).
[robinson]<esprit> make geometry
gfortran -o geometry geometry.o util.o spec.o earth.o ccdfit.o version.o
/Users/donati/lib/libfile.a /Users/donati/lib/libnr0.a
/Users/donati/lib/libmem.a /Users/donati/lib/libplot.a -L/usr/X11R6/lib -lX11
-Wl,-framework -Wl,Foundation -L/sw/lib -lz -laquaterm -lpng -L/sw/lib/pgplot
-lpgplot -lcpgplot
Undefined symbols:
"_png_set_longjmp_fn", referenced from:
_write_image_file in libpgplot.a(pndriv.o)
ld: symbol(s) not found
collect2: erreur: ld a retourn'e 1 code d''etat d'ex'ecution
make: *** [geometry] Error 1
i found a similar report on the web:
http://macosx.com/forums/unix-x11/319812-problem-pgplot-libraries.html
but with no answer on how to proceed to make it work.
any help would be welcome
thanks in advance
