You are using a wrong cpuminer. Delete the directory, redownload the miner from our repository and compile it again:
sudo apt-get install libcurl4-openssl-dev libtool autoconf build-essential
git clone https://github.com/1gh/cpuminer-heavycoin 1ghminer
cd 1ghminer
./autogen.sh
./configure CFLAGS="-O3"
(or ./configure CFLAGS="-O3 -march=native" for the best performance)
make
./minerd -a heavy -v 512 -o stratum+tcp://hvcpool.1gh.com:5333 -u WALLET -p x
