[Boost-users] RE Problems using thread and asio libraries together with Boost 1.36.0 on Cygwin

I had no issue compiling 1.36 on cygwin although I am not using it.

Why -mwin32 and not -mno-cygwin?

Personnaly, I add threadapi=win32  to BJAM_CONFIG in Makefile (after ./configure).
and I use the following user-config.jam:
using gcc : : : <cflags>-mno-cygwin <cflags>-DBOOST_WINDOWS_API <cxxflags>-mno-cygwin <cxxflags>-DBOOST_WINDOWS_API <compilerflags>-mno-cygwin <compilerflags>-DBOOST_WINDOWS_API <linkflags>-mno-cygwin
;

Regards,

F. Bron
