Re: cryptest.sln failing to build

Ah I see, once I ran without debugging it is passing all tests! However I 
am still having trouble actually integrating the library into my project as 
when I build it, it throws LNK2001 and LNK2019 errors whenever I try to 
reference any classes or functions within the crypto++ library. I added the 
path to cryptlib.h in my Additional Include Directories so I'm very 
confused on why I'm unable to compile properly. Do I need to rebuild the 
cryptest.sln within the current project I'm working on? And if so, how then 
do I debug my own code rather than running the cryptest.sln code every time 
I try to run my code?

Apologies for what may be simple questions, I've been coding using g++ and 
gdb for my lower level classes the past 2 years but now I'm in my 
upper-divs and we have to use Visual Studio so I'm still getting the hang 
of the functionality as a whole.

Best,

Josh Weadick
