Hi, I don't know how to build Boost with C++0x compilers. Which option must be used with bjam? Should the user.config file be modified? Can someone help me? Best, Vicente

Vincente, Here's what I have near the top of my user-config.jam: -{--cut here-- import toolset : using ; # Configure gcc # using gcc : 4.4_20090630 : "/home/evansl/download/gcc/4.4-20090630/install/bin/g++" : <cxxflags>-std=gnu++0x ; using gcc : 4.4_20090630_v : "/home/evansl/download/gcc/4.4-20090630/install/bin/g++" : <cxxflags>-std=gnu++0x <cxxflags>-DCXX0X_VARIADIC_TEMPLATES ; -}--cut here-- The second entry is for using variadic templates. Then: bjam --toolset=gcc-4.4_20090630_v or something like this is used to invoke the variadic compiler created in: home/evansl/download/gcc/4.4-20090630/install/bin/g++ HTH. -Larry

Vincente,
Here's what I have near the top of my user-config.jam:
-{--cut here-- import toolset : using ;
# Configure gcc #
using gcc : 4.4_20090630 : "/home/evansl/download/gcc/4.4-20090630/install/bin/g++" : <cxxflags>-std=gnu++0x ;
using gcc : 4.4_20090630_v : "/home/evansl/download/gcc/4.4-20090630/install/bin/g++" : <cxxflags>-std=gnu++0x <cxxflags>-DCXX0X_VARIADIC_TEMPLATES ; -}--cut here--
The second entry is for using variadic templates. Then:
bjam --toolset=gcc-4.4_20090630_v
or something like this is used to invoke the variadic compiler created in:
home/evansl/download/gcc/4.4-20090630/install/bin/g++
Oh yes, using cxxflags. I was locking for a specific Build feature such as c++0x=on common to all the compilers. Thanks, Vicente

It isn't clear to me yet that such a build feature is needed. VC++ isn't requiring any switches for their C++0x stuff. What are other compiler vendors doing? --Beman

I've been using GCC with -std=c++0x. Andrew Sutton andrew.n.sutton@gmail.com

This means that we can not add in our library C++0x dependent code that is activated with a explicit switch. I would prefer that this is actived explicitly, at least for the moment. Thanks for the info Vicente

This affects VC10 mainly. It has the features it has, and no way of turning them on or off. I guess this means that macros BOOST_NO_xxx will not be defined.
This means that we can not add in our library C++0x dependent code that is activated with a explicit switch. I would prefer that this is actived explicitly, at least for the moment.
Wouldn't that be a library specific switch 'don't use even if available'? If the feature is available, and working properly, why not use it? Bo Persson
