Hi,
I am new to LLVM, so I am sorry if the question I am going to ask has already been raised before. I will be thankful if anyone can describe me a quick way to search relevant topics within the list archive,
When I am trying to compile a simple code, containing access to std::string, with clang:
#include
int main()
{
std::string s;
return 0;
}
I am getting a plenty of following errors:
In file included from test_string.cpp:1:

extern __typeof(pthread_once) __gthrw_pthread_once attribute ((weakref(“pthread_once”)));
In one of the development phorums, I found somebody saying that LLVM does not support gcc 4.1 libraries. Is that true? If yes, which libraries should I use, in case I would like to use llvm 2.9?

Clang questions generally go to the clang development list (+ that
list to this email, replies can drop llvmdev).
In general we recommend you used the latest release of LLVM/Clang (3.1
at this time). The project moves quickly & you'll be lacking a lot of
developments if you're not running up to date (even better: running
top of tree/source builds). The same, basically, goes for the
libstdc++ you're running against - more recent versions are generally
better supported. Try 4.7, for example.

Dmitry,
You may install gcc44-c++ if you use RHEL5 (or its clone).
Clang++ is aware of libstdc++-devel-4.4.x.
Please ask cfe-dev for clang issues.
