[gentoo-dev] Minor KDE issue...

[Alastair Nicol]

i've been trying to figure out a seperate kword issue using strace and noticed 
something odd when starting kde apps.

when the apps start-up they try to load various libraries, but quite often try 
several different paths before finding the correct one. example at end of 
mail.

i expect this is "normal" kde behaviour as most people binary install kde and 
kde needs to know where the libs are. but as i've compiled KDE it should know 
exactly where to look.

if you look at the strace there are tonnes of messages like this, i dont know 
how to measure but based on the volumn i would guess it slow's KDE apps at 
startup (yup i already know about the KDE slowdown issue linking to c++ 
libs). this is a minor perf issue, but kde needs all the help it can get.

I've been poking around in gentoo and cannot for the life of me work out how 
kde works out these path names. in the example i havnt got any directories 
i686/mmx to start with! (guess it doesnt help that one language i dont know 
happens to be C)

Can anyone point me in any helpful directions??

Gentoo 1.1a + kde 3 - very standard "off the shelf" install.

Thanks Al
