Everything?

Why would you run ld on a library? do you mean ldd?

You should also have a symlink named libcurl.so.4

Really? I read this list fairly often and very rarely see reports of any
linkage problems (except maybe on Windows)

Try running the "ldconfig" command (as root)

Also, check to see if you can execute the curl command line tool.

If so, compare the output of "ldd /path/to/curl" with
the output of "ldd /path/to/your-app"

Another thing you might want to consider is using either curl-config or
pkg-config to automatically set up the proper linker options, instead of
entering them manually.
