pdfgrep failed to build on 10.8

[plicplic]

Please follow the general troubleshooting steps first:

• [YES] Ran brew update and retried your prior step?
• [YES] Ran brew doctor, fixed as many issues as possible and retried your prior step?

Bug reports:

I know that my old Mountain Lion is not supported anymore but maybe someone may help to get rid of this compile error in make?

That std::unique_ptr is a new C++11 feature. Maybe your older version of clang doesn't support it?

As a workaround, try installing Homebrew's gcc (brew install gcc) and using that, with brew install -cc=gcc pdfgrep.

[DomT4]

This is a 🐇 hole, it turns out.

The clang on 10.8 is "new" enough to have C++11 support, so formulae that need cxx11 are happy to use it. This includes poppler it seems, although poppler doesn't declare the need for cxx11 in-formula. If you build pdfgrep with GCC-5 you run into this:

The only way I can find out of that failure is to remove poppler and then re-install poppler using GCC-5 as well. I increasingly lean harder and harder in the direction of saying we should mandate GCC on 10.8 and below, but that wouldn't help from an existing installation in this case.

The most obvious solution here for an immediate fix is probably just to tag poppler and pdfgrep as fails_with :llvm and fails_with :clang for the respective builds on 10.8 and lower.

Hi, thanks to both of you for your help!

I did the following:

brew install gcc
brew uninstall poppler
brew install -cc=gcc poppler
brew install -cc=gcc pdfgrep

Unfortunately i ran into the same compile error than before.

Here is the new gist link:
https://gist.github.com/anonymous/5728bc928d78a6096c31
(just to be sure, as it is new for me, was I right to call it like this: brew
gist-logs -cc=gcc pdfgrep?

any other clue that could get me out of that trap?

best regards,

Oh, you want:

brew install <formula> --cc=gcc-5

Rather than a plain gcc.

[apjanke]

Sorry! My bad. I have a hard time remembering which of the options and :foo flags need version qualifiers. Also, I got the number of dashes wrong: a -cc=whatever with a single dash will just get you the bottle.

$ brew install -cc=your-mom poppler

(If I had got the double-dashes right, it would have given you an error message.) Sorry.

[plicplic]

No worry, Andrew!

I uninstalled poppler again and reinstalled it with:
brew install --cc=gcc-5 poppler

then tried again
brew install --cc=gcc-5 pdfgrep

But the same error occured, unfortunately.

You'll need to brew update && brew reinstall poppler but afterwards from fairly extensive local testing you should be able to brew install pdfgrep without failure.

[plicplic]

Puzzled! I just ran these two commands you suggested, after all those
errors I explained before:
brew update && brew reinstall poppler
than:
brew install pdfgrep

And it worked in a couple of seconds!

So grateful for your help.

I made some changes our end, so it wasn't anything you did wrong before :). Glad it's working as-expected now. Thanks for the report!
