Re: [Lush-users] Lush2 - 64bit or 32bit and cannot find libsdl.so

[Ralf J. <jue...@cs...>]

Hi Robert,

If you look into sdl-config.lsh you see that the code
tries to locate the SDL library and then define variable
'sdl-libs'. To fix your problem you would set this
variable before loading the sdl package. Ie,

(defvar sdl-libs "/usr/lib/x86_64-linux-gnu/libSDL.so")
(libload "sdl/SDL")


As for the state of lush2, there has been little activity
in the last few years. The wrappers to various libraries
have not been kept up-to-date, so it is not expected that
everything works out of the box.
