Can't use std::thread with CDT and MinGW [message #773927] Mon, 02 January 2012 17:25 Go to next message
Eclipse User
I am wanting to use std::thread with my Eclipse Indigo and MinGW (gcc 4.6.1)
combination on Windows 7 but it reports that thread is not a member of std.
I have included <thread> but when I examine that file it only defines thread
if __GXX_EXPERIMENTAL_CXX0X__ is defined.

How is this variable supposed to get defined? I already use the compiler
option of std=c++0x so what else do I need to do to have std::thread as a
usable class?

Set it in the project properties :

C/C++ General -> Paths and Symbols
Symbols tab
Languages : GNU C++
Add...
Name -> __GXX_EXPERIMENTAL_CXX0X__
Value -> (nothing)

In my case, I have added "-std=c++0x" to Project -> Properties -> C++-Build[Settings] -> G++Compiler[miscellanous] -> Other flags.

By adding -std=gnu++0x to discovery options, a few new symbols are added to my project paths and symbols (after a build and index update) e.g. GXX_EXPERIMENTAL_CXX0X.
