I have errors from pdftk, and the pdf files that come out are unusable. Any suggestions, or links to a usable pdftk source or monolithic bynary? Thanks, Tommaso Toffoli I just installed the pdftk 1.44-5 (AUR package) in a freshly installed Arch Linux 64-bit system. I installed this package first manually, directly from AUR, and a second time using Yaourt, with exactly the same results. [I had used pdftk on the previous install (a couple of months ago) of Arch Linux on the same machine, and that had been working without any problems. Also, the latter installed instantly, while the new one had to go through half an hour of an enormous gcc-gcj installation.] Nature of the problem When I run pdftk I get the following messages: tt@pks:~/beazwork$ pdftk body.pdf cat 645 output page.pdf Unhandled Java Exception: Unhandled Java Exception: java.lang.NullPointerException at gnu.gcj.runtime.NameFinder.lookup(libgcj.so.12) at java.lang.Throwable.getStackTrace(libgcj.so.12) at java.lang.Throwable.stackTraceString(libgcj.so.12) at java.lang.Throwable.printStackTrace(libgcj.so.12) at java.lang.Throwable.printStackTrace(libgcj.so.12) When I play back the resulting file, I get the following messages: tt@pks:~/beazwork$ xpdf page.pdf Warning: Cannot convert string "-*-helvetica-medium-r-normal--12-*-*-*-*-*-iso8859-1" to type FontStruct Warning: Cannot convert string "-*-courier-medium-r-normal--12-*-*-*-*-*-iso8859-1" to type FontStruct Warning: Cannot convert string "-*-times-bold-i-normal--20-*-*-*-*-*-iso8859-1" to type FontStruct Warning: Cannot convert string "-*-times-medium-r-normal--14-*-*-*-*-*-iso8859-1" to type FontStruct Syntax Error: Couldn't read xref table Syntax Warning: PDF file is damaged - attempting to reconstruct xref table...

Mine is a 64-bit system; could it be an issue of 32 vs 64 bits? -- Is there a simpler, perhaps older, monolithic binary that I can use in the interim? -- Any hope I could be running pdftk again any time soon?
