When using the hyperref package, I keep getting this warning that says something like:

Key ftp://ftp.ams.org/pub/tex/doc/amsmath/short-math-guide.pdf is undefined

whenever I include an http link.

For example:




Here is a link to \href{ftp://ftp.ams.org/pub/tex/doc/amsmath/short-math-guide.pdf}{The Short
Math Guide}


I'm using pdflatex.exe to generate the output, and v6.82h of hyperref.sty.

Your example document works fine for me. Is that the full error message you get? What version of hyperref are you using? –  Jake Aug 25 '11 at 0:49
I am using the MikTeX distribution, with TeXlipse as a front end –  bobobobo Aug 25 '11 at 0:49
The full warning text is Key ftp://ftp.ams.org/pub/tex/doc/amsmath/short-math-guide.pdf is undefined document.tex line 7 Problem –  bobobobo Aug 25 '11 at 0:50
Could you include \listfiles in your preamble and look for the hyperref.sty version number near the end of your .log file? –  Jake Aug 25 '11 at 0:55
Your example works fine. But I can get an error ! Package keyval Error: ftp://ftp.ams.org/pub/tex/doc/amsmath/short-math-guide.pdf undefined. if I use angle brackets \href[..]{...} instead of correct braces: \href{..}{...}. So my guess is you didn't check your example but only believe that it demonstrates your real problem. –  Ulrike Fischer Aug 25 '11 at 6:51

I guess you are using TeXLipse?

If this is the case your warnings maybe come from a bug in TeXlipse (this or this).

And the problem is not solved, yet. –  Sven Aug 9 '12 at 14:10
