The default make compiles a GKrellMSS plugin with support for both Esound and ALSA >= 0.9.7 if they are available. Either fftw3 or fftw2 is required. Just: make make install Installs gkrellmss.so in /usr/local/lib/gkrellm2/plugins. To install into /usr/lib/gkrellm2/plugins: make install PREFIX=/usr Or, you can manually install under your home directory with: install src/gkrellmss.so ~/.gkrellm2/plugins The default install of translation files is to /usr/share/locale, so you should probably do a "make install" as root. However, if you don't want any translation files installed, you can probably run as a normal user: make install enable_nls=0 ===================================================================== When you run gkrellm, go to the plugins page of the config and enable "Sound Scope". Note to distribution packagers: I'm not sure if some users could find it an issue to have both Esound and ALSA dependencies compiled in. If so, possibly there could be multiple conflicting gkrellmss packages like: gkrellmss, gkrellmss-esound, and gkrellmss-alsa. Run "make help" for how to compile gkrellmss with support for either Esound or ALSA disabled. But keep in mind that the overhead involved with having multiple packages could get worse in future gkrellmss releases since I'll likely eventually add at least Jack sound server support.
