PDFlib 4.0.0.... any experiences..

Hi there, Months ago I had a bad time getting PDFlib 3.0.0 to compile with PHP.. After I succeeded I was so glad I promised myself to never touch it again.. :-) Well, I now have a barcode font which I need to embed into a PDF document.. I did this a long time ago, but have forgotten what the exact settings were that I used to accomplish this... With some searching I suddenly saw that PDFlib 4.0.0 was available.. !! When I looked at the documentation I got a tinteling feeling in my stomach.. Finally the package comes with all the Tif/Png etc libraries which you first had to download seperately and try to compile with PDFlib.. Further this package has also been adapted to PHP (they even talk about it in the manual!!!) and it seems that you can also load the pdf as some kind of library when starting the script via the 'dl' function.. ( which I don't yet have any experience with..) My question: Who has got some experience with this..? I grabbed a tarball of php-4.0.4pl1 and pdflib4.0.0.. Compiled both and tried to load the library via de dl option.. PHP can't seem to find this.. I am now busy to try and do it the old way and compile PHP with the PDFlib option enabled.. (did copy the /ext/pdf directory from pdflib to my php!) But if possible I would rather use the option in which the library is loaded into PHP as an library.. Speed isues aren't important, I want an easy and flexible way the change PDFlib versions without needing to recompile anything.. I also read that this was possible with the GD library.. I will be glad if I can hear anyone with some experiences with this new PDFlib.. I look forward getting this to work! Thanks in advance.. With kind regards David Bouw
