./configure error but I had install zlib with prefix already.

configure: error: zlib not installed

should add LDFLAGS and CFLAGS to environment variable

设置一下环境变量CFLAGS和LDFLAGS试试，Makefile一般都通过CFLAGS来设置额外的编译选项，通过LDFLAGS来设置额外的连接选项，configure大概也遵循这个规则吧。

[root@linux libpng-1.2.8-config]# export LDFLAGS=-L$ROOTFS_DIR/usr/local/lib

[root@linux libpng-1.2.8-config]# export CFLAGS=-I$ROOTFS_DIR/usr/local/include

[root@linux libpng-1.2.8-config]# ./configure –host=$ARCH-linux –prefix=$ROOTFS_DIR/usr

reconfigure again…
