Hi, The MiniComputer softsynth has problems building on many distros when fltk-1.x is installed alongside fltk2, and/or the #include directories don't match where MiniComputer expects them to be and so the build fails at the configuration stage. In an effort to fix this quite long standing problem, I've adapted the SConstruct to use fltk-config and pkg-config to solve these problems. If you have problems building MiniComputer replace the SConstruct that comes with MiniComputer with the following file (obviously rename it to SConstruct first): http://jwm-art.net/art/text/MiniComputer_SConstruct It works for me on Gentoo (using accept keyword ~amd64). I posted here because: 1) I saw similar questions without answers on the list in the past. 2) I've spent several hours getting this to work so people might benefit from it. 3) I'm a python/scons newbie and hope that those of you with better knowledge can check it for problems (I've only got this to work by using Google, trial, and error). Cheers, James.
