[ome-users] compile error

[Pierluigi Previtali]

Hi, I installed the libpng, first like a slackware package, and then to 
be sure from source, run the lbpng-test with no errors but I always have 
the same error when I'm compiling omeis :

gcc  -g -O2 -I/usr/include/openssl -DHAVE_SSL -I/usr/include/db4 
-L/usr/lib -L
/usr/lib -ldb -o omeis  File.o Pixels.o OMEIS_Error.o auth.o cgi.o 
composite.o d
igest.o method.o omeis.o repository.o sha1DB.o xmlBinaryResolution.o

-lm zoom
/lib/libzoom.a zoom/lib/libpic.a -lz -ltiff -ljpeg -lbz2  -lssl -lcrypto
  zoom/lib/libpic.a(png.o)(.text+0x97): In function `picpng_open':

zoom/lib/libpic.a(png.o)(.text+0x168):/usr/local/src/OME/src/C/omeis/zoom/lib/p
ng.c:69: undefined reference to `png_get_IHDR'

the configure output that could be interesting is:
checking for png_init_io in -lpng... no
  checking png.h usability... yes
  checking png.h presence... yes
  checking for png.h... yes

any clue?
thanks
