Ector is a retained mode drawing library that is designed to work for and with an scenegraph like Evas.
Ector is a library your application links to. The procedure for this is very simple. You simply have to compile your application with the appropriate compiler flags that the pkg-config
script outputs. For example:
Compiling C or C++ files into object files:
gcc -c -o main.o main.c `pkg-config --cflags ector`
Linking object files into a binary executable:
gcc -o my_application main.o `pkg-config --libs ector`
See pkgconfig
After you understood what Ector is and installed it in your system you should proceed understanding the programming interface.
