A linker problem

A linker problem

[Madan Mohan Jampani]

Hi, 
  I have a problem linking a library archive with the gcc 
I have a program the uses the library "liblug.a"
I put this archive in /usr/local/lib ( I put this path in /etc/ld.so.conf and ran ldconfig )
The program uses a function read_gif_file() present in this library..
I try to link using -llug.
But I get a error saying undefined reference to read_gif_file(). 
I did a nm -s /usr/local/lib/liblug.a  | grep liblug.a
and found the function in there....

Please tell me what else I need to check

Thanks
Madan.

... hmmm, ... I thought all the time, that ``ldconfig'' is used for dynamic libs.
 ... add the ``-L /usr/local/lib'' to your command line.

( see info gcc -> Invoking -> Linker Options )

Hope this helps
