Does Apple have any official position on which elements, if any, of
C++ TR1 they are currently supporting and plan to continue
supporting moving forward? I found some TR1 header files under:
/usr/include/c++/4.0.0/tr1
and managed to get
#include <tr1/unordered_map>
to compile. But does this mean these features (e.g.,
unordered_map) are supported?
I was thinking about investing some time learning some TR1 features
(i.e., buy and read a book), but I don't know which if any are
supported by Apple's C++ compiler.
Supported is what you find in the tr1 directory of your installation.
Apple's "current" g++ release is a modded two year old version.
In the meantime two subrevisions (current is 4.2) and three dot
releases of gcc (last of the 4.0. branch is 4.0.4) were released.
Most of them seemed to address quite some C++ bugs.
The maior feature of gcc 4.1 seemed to be optimizer enhancements, the
maior 4.2 feature some steps toward more C++ standard compliance.
Even the 4.2 release does not implement all of TR1 - see <http://
gcc.gnu.org/onlinedocs/libstdc++/ext/tr1.html> . OTOH, there are
plenty other solutions for regex handling, which seems to be THE
maior missing libstdc++ feature.
