is there a way not to type LD_LIBRARY_PATH referring to the *.so everytime you log on

Hi everyone,

I have tried the libusb, a library allowing you to get access to the USB under linux. It is used as an ordinary library. (shared)

While everytime I restart the computer, I have to type the following again:
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
export LD_LIBRARY_PATH
where /usr/local/lib is the place where the library files reside.

Could anybody tell me in which way I can *tell* linux to *remember* automatically the path of the library files? Thank you for any answer.

There should be a file (somewhere) called :

ld.so.conf

(mine is /etc/ld.so.conf {slackware} )
in that file is the paths that are checked for shared libs...
if you do a `locate ld.so.conf` and add to that file the line ,

/usr/local/lib

save and exit then run `ldconfig` you should be good to go...

Many thanks jhorvath. Indeed I once tried to add /usr/local/lib and saved ld.so.conf but did not run "ldconfig". Do I need to specify the path of this command?

Thanks again.

no sir,

you can run it from anywhere (as root of course)...all it does is check /etc/ld.so.conf , /lib , and /usr/lib ...and then updates the links and paths of shared libraries.

have fun with your new found knowledge...also try "man ldconfig" it's all in there
