Re: [Quantlib-users] LINK : fatal error LNK1104: cannot open file 'QuantLib-mt-gd.lib

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

That's correct! Those files are the 64-bit versions of QuantLib.

You'll need to specify Platform=x64 in your project.  Google gives me <
https://learn.microsoft.com/en-us/cpp/build/how-to-configure-visual-cpp-projects-to-target-64-bit-platforms?view=msvc-170>
or <
https://learn.microsoft.com/en-us/visualstudio/ide/how-to-configure-projects-to-target-platforms?view=vs-2022
>.
