Quick installation guide

Here is an example of a list of commands you could use to install ODB API.  It is assumed “>” is the shell prompt.

Code Block
> tar -xzf  ODB_API-x.y.z-Source.tar.gz
> mkdir build ; cd build 

> cmake -DCMAKE_INSTALL_PREFIX=/path/to/where/you/install/odb_api ../ODB_API-x.y.z-Source 
...

> make
> ctest
> make install


It is recommended that you always build in a clean directory and also install into a clean directory.
