Hi Nick, I have downloaded the sources for amSynth-1.3.1, succesfully compiled, and running on my Fedora 17 system. I especially like the fact that I can run it both as standalone and dssi-plugin, including the new GUI. I only needed to apply one little patch to compile succesfully: ---------8<---------------- diff -ur amSynth-1.3.1.orig/src/Config.cc amSynth-1.3.1/src/Config.cc --- amSynth-1.3.1.orig/src/Config.cc 2012-08-11 16:32:24.019592715 +0200 +++ amSynth-1.3.1/src/Config.cc 2012-08-11 16:37:15.608128292 +0200 @@ -8,6 +8,7 @@ #include <iostream> #include <cstdlib> #include <sstream> +#include <unistd.h> using namespace std; ---------8<----------------- In other words: I had to specifically "#include <unistd.h>" in Config.cc I think newest gcc versions are more strict in that, but I guess it doesn't hurt to add that line also for older/other compilers?
