Hi again,
Okay I found libpng.so.3 and it was in /usr/local/lib which is in my
$ldconfig tree. I rebooted to make sure $ldconfig was up to
date. I will give here the exact error I get.
*************************make error********************
checking for a BSD compatible install... /usr/bin/install -c -o root
-g wheel
checking for main in -lm... yes
checking for main in -lz... yes
checking for main in -lpng... no
configure: error: libpng not found.
*** Error code 1
************************************************************
So I know that the lib is there and $ldconfig knows about it. Here is
the configure code that does the actual looking.
************ gd configure file
*****************
fi
if eval "test \"`echo '$ac_cv_lib_'$ac_lib_var`\" = yes"; then
echo "$ac_t""yes" 1>&6
ac_tr_lib=HAVE_LIB`echo png | sed -e 's/[^a-zA-Z0-9_]/_/g' \
-e 'y/abcdefghijklmnopqrstuvwxyz/ABCDEFGHIJKLMNOPQRSTUVWXYZ/'`
cat >> confdefs.h <<EOF
#define $ac_tr_lib 1
EOF
LIBS="-lpng $LIBS"
else
echo "$ac_t""no" 1>&6
{ echo "configure: error: libpng not found." 1>&2; exit 1; }
fi
**************************************************************
I find that editing this configure file just gets me into a bunch of
problems. Anyone have some ideas as to how i can get configure to
recognize the libpng.so.3. Thanks again for all your help.
