Error: Processing of port pdfgrep failed

The log basically states that configure failed to find "poppler_cpp":

I don't have program called "poppler-cpp". Do I have to install the port "poppler" or "poppler-data" first?

[macports.org@…]

I installed port "poppler" (which installed "poppler-data" as a dependency)

bash-3.2# port install poppler +quartz

Installation for "poppler" finished successfully.

Now port "pdfgrep" installs without problem:

bash-3.2# port install pdfgrep +unac

--->  Cleaning pdfgrep
--->  Updating database of binaries: 100.0%
--->  Scanning binaries for linking errors: 100.0%
--->  No broken files found.

Obviously configure's Package requirements "poppler-cpp" are now satisfied (although no program "poppler-cpp" got installed).

Is "pdfgrep" missing a dependency here?

[ryandesign (Ryan Carsten Schmidt)]

I don't know how it was possible for you to attempt to install pdfgrep without already having poppler installed, since pdfgrep clearly does declare a dependency on poppler already, and always has:

$ port deps pdfgrep
Full Name: pdfgrep @1.3.0_1
Build Dependencies:   pkgconfig
Library Dependencies: poppler

[ryandesign (Ryan Carsten Schmidt)]

Perhaps you had poppler installed, but it was broken. What do you get for:

port -v installed poppler

[macports.org@…]

# port -v installed poppler
The following ports are currently installed:
  poppler @0.22.2_0+quartz (active) platform='darwin 12' archs='x86_64'

[macports.org@…]

The dependency to "poppler" is not enforced on my system. MacPorts does not refuse to uninstall poppler:

# port uninstall poppler
--->  Deactivating poppler @0.22.2_0+quartz
--->  Cleaning poppler
--->  Uninstalling poppler @0.22.2_0+quartz
--->  Cleaning poppler

Of course this breaks "pdfgrep":

$ pdfgrep
dyld: Library not loaded: /opt/local/lib/libpoppler-cpp.0.dylib
  Referenced from: /opt/local/bin/pdfgrep
  Reason: image not found
Trace/BPT trap: 5

[jmroot (Joshua Root)]

The unac variant overwrites the port:poppler dependency with port:unac. Presumably it should append instead.

Thanks for the report. Fixed in r105031.
