error on make
 

Hi, I am trying to compile gpsd, a version of it for my earthmate delorme GPS and I get an error on make, I can't seem to figure it out. The website for the version of gpsd that I am using is here http://trans.civil.northwestern.edu/~jay/gpsd.html

Here are the errors I am getting

gcc -o gpsd gpsd.o -L. -lgpsd -lnsl -lm -lc -lusb

I am using redhat 8.0 with stock kernel. I thought it was the libusb so i downloaded the newest version and still get the same error.
HELP
thanks

Did you download a development version of the lib with header files?

The headers may not match the version of the lib and is giving you problems.

I downloaded the current stable, should i have something else?

Most packages dont have header files with libs, so they have a devlopment versions of the libraries that have headers installed as well. Where did you get libusb from?

http://libusb.sourceforge.net/download.html#stable
is there i got it from....

Hmm, this does contain the headers and everthing.

Sorry if you have but I gotta ask...
do you configure make and make install ( as root ) libusb? Also you did set the correct prefix for configure? ( it defaults too /usr/local which would be wrong for most systems. )

I did not set the prefix in configure, what would i set it to?

usually you should set the prefix for /usr ( this is normally where things reside ).

What it is happenning with 'undefined reference to'?
 

I'm working with gnokii proyect and a get the same problem:
undefined reference to 'usb_get_string_simple'

Do I have to update my kernel? I use kernel 2.4.20-8 but my friend laclac01 says that the problem follows.

./configure --prefix=/usr/ --enable-security : this is well
gmake : this is bad. Here is the trouble.

What can/should I do?
