Identical failure on 10.6 PPC too.

usual fix is to add this to cppflags or cxxflags:

-D__STDC_FORMAT_MACROS

Replying to kencu:

-D__STDC_FORMAT_MACROS

Thank you! I found that, but apparently a proper fix will be change the header to <cinttypes>: ​https://en.cppreference.com/w/cpp/header/cinttypes (changing header fixes the problem).
