Download Dolphin from its repository:

svn checkout http://www.sitasoft.net/tdolphin

I had to modify setenvh.sh for my own settings:

export PRG_COMP_PATH=~/harbour

export PRG_COMP_INC_PATH=$PRG_COMP_PATH/include

then do:

chmod +x setenvh.sh

./setenvh.sh

We need to download the MySQL client package:

sudo apt-get install libmysqlclient-dev

We need to link these two libraries to build our apps:

-ldolphin -lmysqlclient

(already included in samples/build.sh)
