So, what's this?
I didn't even know cairo had an --enable-pdf switch. I only use cairo for graphviz, and one of the features graphviz gains by using cairo is the ability to output pdfs. This has always worked for me, though I've never used --enable-pdf. So does --enable-pdf get us anything extra? I see from ./configure --help that the default for this option is "auto" so maybe for me it was automatically on and for you it was automatically off? I wonder what influences this automation. Does the pdf ability need any additional dependencies? If not, shouldn't we enable pdf all the time rather than putting it in a variant?
There are no dependencies apart from those already listed but I don't how the "auto" is worked out. I put it as a variant mostly because I was not sure what effects it could have, but it was not necessarily the best approach.
I think that for cairo the best approach for handling the PDF backend would be to explicitly enable pdf be default and provide users who don't want it the ability to turn it off (ie --disable-pdf) Randall Wood rhwood@mac.com http://shyramblings.blogspot.com "The rules are simple: The ball is round.
