What does port -v installed pdftk say? How about trying port -v installed rdepof:pdftk too?

What did you change in the last 4 days? Did you upgrade one or more of pdftk's rdeps?

pdftk is to be updated to a newer version, once I can verify that it works; see #37580. Perhaps that will solve the problem.

I did update about four days ago, but I seem to have an example of where pdftk worked three hours after that update. After the initial problem, I uninstalled and re-installed pdftk this morning with no effect. Is there a way to ensure that this is done cleanly? Since filing the error report, I have downloaded and installed the pdflabs version, and it seems to work OK, but I would like to have my macports version working again.

comment:4 Changed 8 years ago by bernard@…

I just realized that the version I have from pdflabs is version 1.45.

comment:5 Changed 8 years ago by cooljeanius (Eric Gallager)

Hm, all I can suggest is switching from the +gcc45 variant to the +gcc47 variant, since that's the current default...

comment:6 Changed 8 years ago by ryandesign (Ryan Schmidt)

Which gcc variant is default for pdftk currently varies by OS version, although if it will work, I would like to eliminate all options other than gcc47 when updating pdftk to 1.45.

comment:7 Changed 8 years ago by bernard@…

I'm running Mac OS X 10.6.8. I don't know which gcc complier the pdflabs version (pdftk 1.45) is depending on. I could try to install the the gcc47 version from macports (how do I do that?) but I see that is still version 1.44. Is there a way to try the version 1.45 from macports?

I can confirm similar problems. Running OSX 10.6.8, macports 2.2.0 and pdftk @1.44_0+gcc45 (active). Is there some fix for this issue?

I installed pdftk today on my 10.6 machine just after a selfupdate and upgrade outdated and I have the same malloc error.

I deactivated pdftk and installed pdftk +gcc47: the error disappeared and pdftk is working as expected.

This error is generally caused by a conflict between different versions of libstdc++.dylib. The one installed by the gcc ports and the one installed by the system interact in an unfavourable way, where objects are created by one version and attempt to be released by the other. The fact that it disappeared later on with gcc changes is more-or-less just luck.

There are two known fixes so far.

  1. use DYLD_LIBRARY_PATH set to the macports-installed libstdc++.dylib location (currently ${prefix}/lib/libgcc
  2. replace the system's /usr/lib/libstdc++.dylib with the current one being used, or at least a much newer one.

The first option is obviously much simpler, but relies on setting that env var all the time, either in binary wrappers or in the .profile.

The second option is tempting -- we are discussing this with the gcc leads -- but it is bound to cause concerns, and it is difficult to test out every possible existing executable that is linked to the current version, so realistically, this is likely to never happen.

pdftk hasn't seen any recent development; I consider it dead. I recommend using pdftk-java instead.
