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

[Jonathan S. <sw...@gm...>]

Hi Christofer,

Is your hello world program in the same custom folder where you installed
QuantLib? If so then the best thing to do would be to make a new separate
directory for your hello world program and then pass the QuantLib include
directory to the compiler using the `-I` flag.
