Greetings: I'm slogging away at compiling Csound5 (aka Csound: The Next Generation), and I learn that I probably need to configure FLTK for thread support. Joy, bliss, rapture. So, should I uninstall the Planet C package or trust to a parallel install (/usr and /usr/local) ? Surely there's no simpler way to achieve the Goal ?... Best regards, dp
