boost/thread.hpp doesn't compile with MinGW and -march=pentium3

[Marcin Wojdyr <wojdyr@…>]

I get the same with two 32-bit MinGW-w64 versions: from g++ 4.8.2 from MSYS2 and g++ 4.8.1 from mingw-builds. This problem doesn't exist in boost 1.53.

$ cat test.cpp
#include <boost/thread.hpp>

$ /mingw32/bin/g++ -I./checkout/boost_1_55_0 -march=pentium3 -c test.cpp

Googling around I've found the same error message here: ​http://pastebin.com/4nXK0V73

I'm not the owner of boost/detail/interlocked.hpp. Moving to SmartPtr in case Peter Dimov is aware of the issue.

[Peter Dimov]

This should be reported as a MinGW bug - their <intrin.h> header doesn't compile under -march=pentium3.

To get around this issue, try defining BOOST_USE_WINDOWS_H. This will force interlocked.hpp to include windows.h instead of intrin.h.

thanks for looking into it

I reported it to Mingw-w64 then ​https://sourceforge.net/p/mingw-w64/bugs/383/

I'd close this ticket, but apparently I don't have permissions to do it.

OK, closed.
