fatal error: geos_c.h: No such file or directory

My steps used to compile monetdb src and to install monetdb are:

a. Environment setup:

$ export MonetDB_rel=July2017

$ export MonetDB_ver=11.27.5

$ export MonetDB_base_dir=$HOME/MonetDB-$MonetDB_rel

$ export MonetDB_source_dir=$MonetDB_base_dir/MonetDB-$MonetDB_ver

$ export MonetDB_build_dir=$MonetDB_base_dir/BUILD

$ export MonetDB_prefix_dir=$MonetDB_base_dir

$ mkdir $MonetDB_base_dir

$ cd $MonetDB_base_dir

b. Download the latest version:

$ wget https://dev.monetdb.org/downloads/sources/Jul2017-SP1/MonetDB-11.27.5.tar.xz

$ tar xf MonetDB-$MonetDB_ver.tar.xz

c. Build:

$ mkdir $MonetDB_build_dir

$ cd $MonetDB_build_dir

$ MonetDB_source_dir/configure --prefix=$MonetDB_prefix_dir

d. Install:

$ make -j 20 (error mentioned above occurs here)

$ make -j 20 install

Thanks,
