thread compilation with MingW/gcc on Windows gives errors

[Edward Diener]

When building the threads library with MingW/gcc on Window the following errors are seen:

"..\..\..\..\libs\thread\src\win32\thread.cpp: In static member function 'static unsigned int boost::thread::physical_concurrency()': ..\..\..\..\libs\thread\src\win32\thread.cpp:425:51: error: 'GetLogicalProcessor Information' was not declared in this scope

GetLogicalProcessorInformation(NULL, &size);

..\..\..\..\libs\thread\src\win32\thread.cpp:429:21: error: 'SYSTEM_LOGICAL_PROC ESSOR_INFORMATION' was not declared in this scope

std::vector<SYSTEM_LOGICAL_PROCESSOR_INFORMATION> buffer(size);

..\..\..\..\libs\thread\src\win32\thread.cpp:429:57: error: template argument 1 is invalid

std::vector<SYSTEM_LOGICAL_PROCESSOR_INFORMATION> buffer(size);

..\..\..\..\libs\thread\src\win32\thread.cpp:429:57: error: template argument 2 is invalid ..\..\..\..\libs\thread\src\win32\thread.cpp:429:65: error: invalid type in decl aration before '(' token

..\..\..\..\libs\thread\src\win32\thread.cpp:430:52: error: request for member ' front' in 'buffer', which is of non-class type 'int'

if (GetLogicalProcessorInformation(&buffer.front(), &size) == FALSE)

..\..\..\..\libs\thread\src\win32\thread.cpp:436:25: error: invalid types 'int[s ize_t {aka unsigned int}]' for array subscript

if (buffer[i].Relationship == RelationProcessorCore)

..\..\..\..\libs\thread\src\win32\thread.cpp:436:43: error: 'RelationProcessorCo re' was not declared in this scope

if (buffer[i].Relationship == RelationProcessorCore)"

The MingW Windows library does no have the GetLogicalProcessorInformation functionality used by the thread library.

Tim please could you take care of this issue?

[timblechmann]

which version of mingw is this? i cannot reproduce it with mingw from mingwbuilds.

[Edward Diener]

I am using the latest MingW with gcc 4.8.1. The errors occur when I try to build Boost from the top-level directory using the 'master' branch.
