Re: [Quantlib-users] Failing to run Quantlib 'Hello World' code

[Christofer B. <bog...@gm...>]

Hi Jonathan,

Please ignore my last response. I followed your suggestion and
executed below code from Mac's terminal

cd "/Users/AAA/" && g++ Hello_World_QL.cpp -o Hello_World_QL -I
"/Users/AAA/QuantLib/QL/include"  && "/Users/AAA/"Hello_World_QL

Above code seems to execute QL code perfectly but stopped in executing
boost. It generates below error,

fatal error: 'boost/config.hpp' file not found

My installation folder for Boost is "/Users/AAA/Other_folder/Boost"

Given that there are many places in QL where Boost is called, is there
any centralized way where I can define the Boost path, instead of
changing all QL hpp files everywhere Boost is called?

Thanks for your time.
