Crypto++ Version 5.6.0

anyone used the latest version of cryptopp. i think its 5.6.0. I have a solution working in unix. but in windows I am stuck. Anyone here already using cryptopp 5.6 in vs2008 could you please give very specific instructions on how you compiled this? i have also posted in the cryptopp user groups for an answer. There are some instructions but for vs 6.0 and not the version i am using. So, I am not sure how to proceed.

The errors are as follows: error: lnk2005 already defined in cryptlib(iterhash.obj) (cryptlib.obj)

+1 A:

All I did was open the cryptest.sln file and tell it to build.

EDIT: Visual Studio did have to convert from VS2005 format but it compiles and runs just fine.

ok i did that already and it creates an output\debug directory with the cryptlib.lib after that do i just add that to the linker and thats it?

That is correct.

Oh: Note that you need to ensure you use the debug build of the library with your debug builds and the release version with your release builds. ;)

i think that might be the issue i have. getting a lot of lnk2005 errors. so i build it with debug (active) my solution also has debug(active) both in win32. i am very new to vs2008 so this is a bit new to me. i did not make a release version yet. been just working with debug version. some of the stuff i am seeing is warning : lnk4044 unrecognized option /lcryptopp; ignored. error: lnk2005 <a bunch of stuff> already defined in cryptlib(iterhash.obj) (cryptlib.obj) etc etc any ideas?

i just moved the cryptlib.lib into solutions explorer after it was made and thats it. then just did a build all of my solution that is how I am doing it but yet experience the aforementioned errors.

Make sure you are building the library with the same versions of the C runtime. Crypto++ by default builds with the static runtime, but when you create a project in Visual Studio, you get the DLL runtime by default. To change this, rightclick on the project, hit properties, go to C++ -> Code Generation, and change `Runtime Library` to the non DLL version for your project. Also, it would be helpful to others if you would edit the specific errors you are getting into your question.

well sir you are awesome. that worked! but only one thing is left. when i start without debugging or with for that matter it says "unable to start program.exe. "The system cannot find the file specified". this is after the program compiled and linked correctly.
