thanks in advance

this should help ya to understand it and know what to do.

that doesnt solve it

try doing an ldconfig command. that way the configure file knows where the librarys are.

there you go.

ok, first find out where you cpp/ directory is in. its supposed to be in your /lib/ dir but apparently not.
once you found it go back to your wget directory and type in ./configure --help.
there you should be able to readjust the CPP directory variable by entering:
./configure CPP=<where ever the directory is>

give this a shot.

the only other file called cpp is /usr/bin/cpp

if this helps...

i'm thinking that Slackware 9.0 doesnt have the required cpp program.
you might want to update cpp or updat to Slackware 9.1 or 10.0.
sory but thats all i can think of o_0
