How can I find my gmp library

[Bin YANG]

When I was build the sfslite, I configured it with --with-dmalloc, but I got
the following error:

checking for GMP library... checking for gmp.h... yes
checking for libgmp... configure: error: Could not find gmp library

I donwload the gmp-4.2.1.tar.bz2, and install it as follows:
./configure --host=x86
make
make check
make install

But the same error still exists.

What should I do?
