Re: [Quantlib-users] Fatal Error Installing QuantLib

[Luigi B. <lui...@gm...>]

Nathaniel,
    I second Jack's suggestion to use "pip install QuantLib".

Anyway: the error you're getting (can't find the library) suggest that
either:
- you didn't compile QuantLib, which is unlikely but I'll list it for
completeness;
- there's a mismatch, such as if the library was compiled in Debug
configuration and the wrappers are being compiled in Release, or 32-bits vs
64-bits;
- the library path for the compiler doesn't include the location where the
library is.

Hope this helps,
    Luigi
