Using GCC's C++0x mode in production?

Question

Is anyone using the GCC 4.4.0 C++0x support in production? I'm thinking about using it with the latest MinGW, but I'm not sure if it's mature enough.

I'm interested in:

• TR1 support
• auto
• initializer lists

Answer 1

I'm not using GCC 4.4.0 C++0x support in production but I'm using the TR1 features with the help of the Boost Library http://www.boost.org/.

The Boost Library is well tested and often used in production environments. If you convert to the C++0x standard later the only thing you have to do is changing your include Directives http://www.boost.org/doc/libs/1%5F40%5F0/doc/html/boost%5Ftr1.html.

In my opinion it's currently better to use the Boost Library until the standard is finished. It's a much more compiler independent way.

Answer 2

IMHO, TR1 support and auto are safe to use. In the case of auto it was one of the first features to be included into the standard and is a relatively small change to the language. I would therefore have no problem using it.

I would be a bit more hesitant about using initializer lists. On some other forums (eg. comp.lang.c++.moderated) there are questions about their behaviour and its possible that they may change closer to the release of the standard.

Answer 3

MinGW simply won't compile with '-std=c++0x'. Strange enough, '-std=gnu++0x' works. Anyway it seems buggy and I won't count on it.
