Problem building and using Crypto++ on Windows (Visual Studio)

[jensmue...@gmail.com]

Hi, 

I'd like to build and use Crypto++ on Windows (64bit).

So far I used VisualStudio 2012 to compile Crypto++ 5.6.5 to generate the static libary cryptlib.lib. According to the output, this should have completed successfully.

I set up a simple project in VistualSutio 2012 (I used this AES encryption code), included the header files and gave a refrences to the cryptlib.lib file.

However, when compiling errors of the following form appear:

"error LNK2001: unresolved external symbol ""protected: virtual void __thiscall CryptoPP::CBC_Decryption::ResizeBuffers(void)" (?ResizeBuffers@CBC_Decryption@CryptoPP@@MAEXXZ)". "

Does this mean that definitions / implemenations for some header files are missing? Does more than the cryptlib.lib file have to be included?
Or can you maybe spot a mistake in how I set up the project / created the cryptlib.lib file?

I gave a detailed step-by-step instruction of what I did in this github issue.

It would be great if someone could help me.

Best regards

Go to Start -> Programs -> Visual Studio 2012 -> Developer Tools. Open a VS2012 x64 Command Prompt. 'cd' to you Crypto++ project. Then, issue

    msbuild /t:Build /p:Configuration=Debug;Platform=x64 <your project>.vcxproj

Copy/paste the output into this question.

Thank you Jeff.

Executing your command let me to the error "x64 build: error MSB8013: This project doesn't contain the Configuration and Platform combination of Debug|Win32".

ConsoleApplication was created with the x32 platform as a default. I had  to right-click on the project and then "properties > configuration manager" and at "platform" change x32 to x64. Also, at "Properties > Configuration Properties > VC++ Directories >Library Directories" there was "$(WindowsSDK_LibraryPath_x86)" which I had to delete and check the box that all properties shall to be inherited. At "Properties > Configuration Properties > C/C++ > Code Generation > Runtime Library" I had to switch to MT.

I am now able to build and run the sample application with both the x32 and x64 platform (using cryptlib.lib at Win32\Output\Release and x64\Output\Release respectively).

Thank you!
