I'm cross-compiling curl library for arm board. So I configured Makefile using configure script file in curl library directory like this.
./configure --disable-static --enable-shared --with-ssl=/tmp/openssl --prefix=/tmp/curl --host=arm
But the result is always static library. How do I fix it?

You may be missing dynamic versions of zlib and openssl libraries. One of many possible procedures for building a dynamic curl executable for ARM could be:
