Is there a way to install the suitable libraries when ekiga is installed and avoid saving 2 set of libraries for ekiga? Actually sse2 optimized is very important for ekiga. The improvement is about %5 from test. The sparc version is also needed to be optimized. >> Is the sparc version needed to be optimized? >> >> Do you have some tests to verify any improvement? >> >> Doug > I have just good look at ekiga.spec, and the first thing I thought > was, shouldn't this file be split up into > ekiga.spec, libsdl.spec, pwlib.spec, and opal.spec? > If libSDL is seperated from ekiga.spec, I think ekiga.spec should be split into parts for libs.
