I have recently become interested in Ruby as an alternative to Python. I
was amazed at how easy to use Ruby's C API seems to be, so I decided to
try it out.
I went ahead and started wrapping one of the most fun libraries I know
of: The Open Dynamics Engine.
I started wrapping the world object with a getter and setter for
gravity. The code can be found here:
I compiled with:
gcc -fPIC -I /usr/lib/ruby/1.8/i486-linux -I /usr/include/ode -g -O2 -c
ode_world.c -o world.o
cc -shared -o world.so world.o -lc
After compiling I fired up irb and ran a require("world"), then called
ODE::World.new. After which irb quitted, reporting:
irb: symbol lookup error: ./world.so: undefined symbol: dWorldCreate
Whatever causes that error?
Thanks for the help.
