poppler: fails to build on Leopard with undefined symbols due to old gperf

[rmottola (Riccardo)]

Poppler fails on 10.5 with these missing symbols:

I am compiling with gcc7 (since clang has infamous realpath issue)

here on i386

reproduceable on both i386 and PPC!

BTW -- I fixed the realpath issue with clang-7.0 with this patch (I hope! -- works for me!)

​https://github.com/macports/macports-ports/blob/master/lang/llvm-7.0/files/2003-patch-clang-7.0-allow-asm-redefinition.diff

I hope to someday come up with a better fix, but this works for now.

Interesting bug report, looks possibly related:

[kencu (Ken)]

FYI, poppler installed on Leopard Intel for me (after the snowmath.h fix):

 port -v installed poppler
The following ports are currently installed:
  poppler @20.12.1_3+boost (active) requested_variants='' platform='darwin 9' archs='i386' date='2021-09-27T18:43:04-0700'

it built with clang-7.0. Trying with gcc7 now.

[kencu (Ken)]

gcc7 built it too. Hmmm. I do have MacPorts gperf installed ...

[kencu (Ken)]

Yep, that's it.

It's gperf.

Build fails if MacPorts' gperf is not installed. I guess the one that comes with Leopard is too old.

[rmottola (Riccardo)]

I confirm, both on PPC and i386 I built poppler after having installed gperf.

Maybe we can add a dependency for older Macs?

[jmroot (Joshua Root)]

Easier to turn off regenerating the files so it doesn't need gperf at all, I think. -DRUN_GPERF_IF_PRESENT=OFF according to the upstream bug Ken linked.
