First of all, did you run "sudo ldconfig" each time after installing what ever is needed? If you didn't miss to run ldconfig all the times, did you install all optional dependencies? Are the paths for LV2 and LADSPA set correctly? Dunno if there are already issues regarding to a host? Nedko announced to stop LV2 support . Did you also try the download this version from here? <A HREF="http://sourceforge.net/apps/gallery/calf/index.php?g2_itemId=81">http://sourceforge.net/apps/gallery/calf/index.php?g2_itemId=81</A> [1] Regards, Ralf [1] [spinymouse@archlinux Desktop]$ wget <A HREF="http://garr.dl.sourceforge.net/project/calf/calf/0.0.18.6/calf-0.0.18.6.tar.gz">http://garr.dl.sourceforge.net/project/calf/calf/0.0.18.6/calf-0.0.18.6.tar.gz</A> [<A HREF="mailto:spinymouse@archlinux">spinymouse@archlinux</A> Desktop]$ tar xzvf calf-0.0.18.6.tar.gz [<A HREF="mailto:spinymouse@archlinux">spinymouse@archlinux</A> Desktop]$ cat calf-0.0.18.6/INSTALL To compile and install Calf, you need: - POSIX-compliant operating system - G++ version 4.0 or higher (tested with 4.1.3) - GTK+2 headers and libraries (glib 2.10, gtk+ 2.12) Optional but recommended: - JACK header and libraries (tested with 0.109.0) - LADSPA header - DSSI header - LV2 core </BODY> </HTML>
