[geos-devel] Help with Compiling

[Rookie GIS]

Hello Everyone

I recently downloaded Geos Library and have installed the same on linux 8.0. 
  However, I am having problems compiling the source examples.  I have 
followed all the instructions given in the install file: a) configured with 
env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure b) did a make 
install c) updated the /etc/ld.so.conf file and ran the ldconfig.

In the examples given I added the path for the header files 
/usr/local/include/geos and tried to compile using g++.  I get the following 
errors:

I would be thankful if someone can help me get started and help me with the 
above.

Thanks
