From: Wim Vander Schelden Date: 2006-12-29T06:45:48+09:00 Subject: Re: Ruby extension issue I was able to fix the problem by changing my extconf.rb to: require 'mkmf' dir_config('gamer') have_library("SDL", "SDL_Init") have_header("SDL/SDL.h") pkg_config("sdl") create_makefile('gamer') However, I don't know *WHY* it works. The pkg_config seems to be the crucial line. I just went through other people's extconf.rb files and guessed the "sdl" value. Any help would be appreciated, since there seems to be no documentation about pkg_config...
