fatal error: 'tr1/functional' file not found

pficommon does not build on OS X 10.9 or later, because it uses the transitional "tr1" namespace which is no longer available in OS X 10.9 or later:

pficommon-26b6655092adc95649c39706b37502e466e5efe9/src/concurrent/../lang/function.h:35:10: fatal error: 'tr1/functional' file not found
#include <tr1/functional>
         ^
1 error generated.

Note: if you want to retain compatibility with OS X 10.8 or earlier, you have to continue using "tr1" on those systems. So you'll have to detect whether "tr1" exists or not and act accordingly.

Thank you for reporting. We made pficommon for OS X 10.9+ https://github.com/gwtnb/homebrew-pficommon/ but porting some functions to OS X 10.9+ takes time. We are using pficommon primarily for GNU/Linux, so we will port to OS X 10.9+ if we have to do so.

I'm writing on behalf of the MacPorts project, where we currently have pficommon 83ea9e1 from 20141020. It only builds on OS X 10.7 and 10.8, but not on earlier or later versions of OS X; this is somewhat limiting.

It looks like in the Homebrew formula you referred me to, an earlier version of pficommon from 20140813 is being used. I suppose we can downgrade pficommon in MacPorts to an older version if that will bring compatibility with a wider range of OS X versions, but it would be good to get the current version working on more OS X versions. The problem I mentioned above, about the tr1 namespace, isn't exactly an OS X-specific issue; I imagine you would see the same problem on any other system that has moved from the transitional implementation to the final implementation.

Your latest code still does not build with libc++.

You don't need a Mac to reproduce this issue, since libc++ is available for many systems.
