Build PDFtk Server from Source

PDFtk Server can be compiled from its source code. PDFtk Server is known to compile and run on Debian, Ubuntu Linux, FreeBSD, Slackware Linux, SuSE, Solaris and HP-UX.

Download and unpack the source:

curl -LO https://www.pdflabs.com/tools/pdftk-the-pdf-toolkit/pdftk-2.02-src.zip
unzip pdftk-2.02-src.zip

Review the pdftk license information in: license_gpl_pdftk/readme.txt.

Review the Makefile provided for your platform and confirm that TOOLPATH and VERSUFF suit your installation of gcc/gcj/libgcj. If you run apropos gcc and it returns something like gcc-4.5, then set VERSUFF to -4.5. The TOOLPATH probably does not need to be set.

Change into the pdftk sub-directory and run:

cd pdftk
make -f Makefile.Debian

Substitute your platform's Makefile filename as needed.

PDFtk has been built using gcc/gcj/libgcj versions 3.4.5, 4.4.1, 4.5.0, and 4.6.3. PDFtk 1.4x fails to build on gcc 3.3.5 due to missing libgcj features. If you are using gcc 3.3 or older, try building pdftk 1.12 instead.

Yes. You can encrypt with owner and user passwords using the owner_pw and user_pw flags, and decrypt by providing the password with input_pw.
Does this handle PDF form filling?
Yes. You can populate form fields from FDF/XFDF data files and flatten the result to prevent further edits.
