Different compilers seem to have different ideas about TR1. G++ only seems to accept includes of the type: #include <tr1/unordered_map> #include <tr1/memory> ... While Microsofts com...

I'm using MS VC 2008 and for some projects Intel C++ compiler 11.0. Is it worth using tr1 features in production? Will they stay in new standard? For example, now I use stdext::hash_map. TR1 defin...

I have written a class using std::tr1::regex, and I don't know how to link it. I get (sorry for the large dump...) : $ g++ DictReader.cpp -std=c++0x /usr/include/c++/4.4/tr1_impl/regex:2255: warn...

I have a question related to understanding of how python dictionaries work. I remember reading somewhere strings in python are immutable to allow hashing, and it is the same reason why one cannot...

I couldn't find anything regarding this on http://msdn.microsoft.com/en-us/library/bb982727.aspx. Maybe I could use '[^]+' to match everything but that seems like a hack?

I'm writing some stuff using the tr1 namespace in VS2008. What will happen when C++xx becomes ratified? Has this happened before with other C++ revisions? Will the tr1 stuff still work or will I ha...

I was wandering how it's possible to reverese strings that are contained in a vector using a single for_each command just in one "simple" line. Yea, I know it is easy with a custom functor, but I ...

I'm trying to typedef either an unordered_map or std::map depending whether there are TR1 libraries available. But I don't want to specify the template parameters. From what i've read so far, typed...

I'm in the process of implementing a binary tree in C++. Traditionally, I'd have a pointer to left and a pointer to right, but manual memory management typically ends in tears. Which leads me to my...

Are there any differences between boost::shared_ptr, std::tr1::shared_ptr and the upcoming (in C++0x) std::shared_ptr? Will porting from one to another have any overhead or are they basically the ...

recently I've been reading through Scott Meyers's excellent Effective C++ book. In one of the last tips he covered some of the features from TR1 - I knew many of them via Boost. However, there wa...

How to do intersection and union for sets of the type tr1::unordered_set in c++? I can't find much reference about it. Any reference and code will be highly appreciated. Thank you very much. Upda...

I am working on a platform with a gcc compiler however boost cannot compile on it. I am wondering what is the proper way to include the shared_ptr in std:tr1 on gcc? the file i looked in said not ...

I need to map a pair of long long to a double, but I'm not sure what hash function to use. Each pair may consist of any two numbers, although in practice they will usually be numbers between 0 and ...

I've had a hard time finding references in the TR1 documentation concerning shared arrays. The Boost documentation is fairly clear that there is a significant difference between the C++ "new" and "...

I have class with a member function that takes a default argument. struct Class { void member(int n = 0) {} }; By means of std::tr1::mem_fn I can invoke it: Class object; std::tr1::mem_fn(&a...

Now that shared_ptr is in tr1, what do you think should happen to the use of std::auto_ptr? They both have different use cases, but all use cases of auto_ptr can be solved with shared_ptr, too. Wil...

I need an associative container that makes me index a certain object through a string, but that also keeps the order of insertion, so I can look for a specific object by its name or just iterate on...
