Thanks a lot Peter!

I followed your instructions and re-compiled QuantLib, now I can run my project on Mac with no error.

I read some google search result regarding this, and changed CXXFLAGS  to -stdlib=libc++

The configure step passed, but there was error at compile

Thanks again!

Regards

Jerry

Hi Jerry,

I think compiling QuantLib with C++11 will solve the boost issue, i.e.
configure it with something like

./configure CXXFLAGS="-std=c++11 -g -O2 -Wno-deprecated-declarations"
(... your other options, if any ...)

The last flag silences a lot of warnings showing up because auto_ptr
is deprecated in C++11.

Also, here are two links which might be of interest for you in this context.
