[pdp-discuss] Linux Problem

[Brad Aisa]

Hi Reza,

Make sure the libs, ex. libpdp.so actually exist in the dir:
/usr/local/pdp++/lib/LINUX -- if they are links, make sure that 
the files actually exist where they are pointing (sorry, not a 
3.2 guru, and no access to a system at the moment with it.)

If they do, I'm not quite sure why the LD_LIBRARY_PATH doesn't 
work. (Note: I made a mistake in my directions regarding the 
.bashrc file -- don't use $CPU -- just use LINUX -- but if it 
doesn't work at the console, it is not likely to work in .bashrc)

BTW, since I'm not sure of how familiar you are with Unix, I just 
want to make sure that you know that if you make a change to an 
environment variable, like VAR=value in the console, it only 
affects that specific console session, so you can't try running 
some other way. Also, when you make changes to .bashrc and other 
such files, they only affect *new* console sessions.

If none of the above helps...

You could try creating symbolic links to a location where the 
loader will look by default. I'm pretty sure it looks in the same 
folder as the bin, so you could try:

cd /usr/local/pdp++/bin/LINUX
ln -s /usr/local/pdp++/lib/LINUX/lib* ./

(note: make sure links for all the libs appear, in case i've made 
a mistake in the syntax of the wildcard command)

or, as a last resort, you could try into a system lib folder:

cd /usr/lib
ln -s /usr/local/pdp++/lib/LINUX/lib* ./
