please send in your help in this regard

Undefined references usually result from failing to include the requisite header file(s).

Dear Rod ,
thanks for your reply ,

as you suggested that it might be the problem of heard files . I think the curl hearder file is read properly because if i not include the hearder file for curl the errors become like this

Which distribution is this and which kernel?

i have tried it on RHEL4 and fedora core4 and both give the same errors , i am sure it is some curl configuration issue .

Yup!
Must be, because I installed fuse from source on four systems without anything that looks like that, what about removing curl and installing fuse first, then re-install curl. I don't know what the curl stuff is, but those are the steps that work most often with Fedora 6's "dependency hell". I was asking about the kernel just in case it was 2.6.20 or above where you don't need to compile the module for fuse.

On my distro, I found a bunch of your symbols defined in /usr/include/curl/curl.h Have you #included that?
