Hi Dale,
    if MinGW is anything like Linux, I'd try

./configure CXXFLAGS="-m64"

I’ve read the quantlib.org installation guide and done some web searches on this topic. I’ve also looked at configure help and read the QuantLib configure script as well. How do I explicitly get a 64 bit build using configure and MinGW? I tried


set CXXFLAGS="-m64"

set ARCH="x86_64"


followed by running configure in the msys shell, but objdump tells me the resulting QuantLib static library is i386. Does anyone else have any ideas how I can pass –m64 to g++?
