[Boost-users] Réf. : Re: troubles linking with boost_regex

As you may have seen in later post, I have found a solution: I run configure and then add <cflags>-mno-cygwin in user-config.jam before running bjam. I do not use anymore Windows bjam but cygwin bjam.
Thanks,

F. Bron

threading=multi is the default, and the cause of the error messages: the
regex lib is expecting a pthread lib.  Try threading=single, or else build
with regular Mingw which I know does work :-)

Looks like a configuration issue: we should be using Win32 threads when
building with Cygwin and -mno-cygwin.  I'll look into that when I get a
chance.

John.
