Hi, I just wanted to share that I got Csound from CVS to build for Mac Leopard using doubles and with functional FLTK windows. It seems that there are some conditionals missing in SConstruct in order to properly name the libraries with the "64" suffix when building for Darwin. I just added them manually in a hackish way and got it built, installed and running. Regarding the problem with FLTK windows not being movable it can be solved by doing a svn checkout of the 1.1.x branch instead of using the one available through MacPorts and using that for building Csound. Cheers! Hector
