Re: [cryptopp-users] Problems using the library in my application

> Shouldn't the source code be structured such that the core library source files have their own folder? It appears the source code is dumped in with test programs, benchmark programs, and other things that I'm not sure what they are.

Everything is dumped in the root folder to help various tools. In the
past tools like debuggers and disassemblers had problems finding
object files and debug symbols.

Even today, you sometimes need to add options like
-fdebug-prefix-map=<src>=<dest> for Linux.

Users also have a hard time finding things if things get tucked away
into folders.

To avoid all the problems caused by tools and missing artifacts,
everything gets dumped in the root folder, including object files on
Linux & Unix.

It is a pretty good strategy because it minimizes mailing list questions :)

> Some people want to be able to build the files as part of their project rather than using your provided project files. Shouldn't this be easy to do?

Yes.

What problem are you having?

> Also, I tried building the library using cryptdll.vcproj that was inside vs2005.zip (using Visual Studio 2019). I got 907 warnings and one error.

Typically you use the *.vcxproj files with Visual Studio 2010 and
above. The *.vcxproj are unpacked in the root directory. Just click on
the Visual Studio solution file.

> Has anyone else successfully built the library using Visual Studio?

Yes. I built the projects several days ago. That was testing with
VS2012, VS2013, VS2015 and VS2017.

I also tested ARM and ARM64 builds using our NMake project file at
https://www.cryptopp.com/wiki/Nmake_(Command_Line).

I did not test the VS2005 project files, however. They are probably
broke at the moment. They don't get much attention nowadays Since
Visual Studio 2010 made its appearance.

The problems I'm having is trying to sort out which files I need. For example, those with main() defined in them probably won't work being compiled into my application. I couldn't disagree more with the layout, but I understand people think differently.

I was able to use the solution to build without errors. My preference would've been to add the project to my existing solution. But I can see this just isn't going to work the way I want it to work.

Beyond that, in trying to use the library, I'm having trouble figuring out which header files I need. I hoped there was one that would do it but now I'm doubting that's the case. I've posted another question about that.

Thanks for taking time to respond.

If you have access to a Linux machine, then run 'make sources'. It
tells you what sources go where. See below.

Visual Studio is a little different than Linux, however. Visual Studio
has a few *.asm files you will need. They are Microsoft assembler
(MASM) source files. They don't show up under Linux.

$ ls *.asm
rdrand.asm rdseed.asm x64dll.asm x64masm.asm

Another place you can look at is cryptest.nmake. The Nmake file
includes a list of artifacts for LIB_SRCS and LIB_OBS. See
https://github.com/weidai11/cryptopp/blob/master/cryptest.nmake.

Finally, you can look in the cryptlib.vcxproj file. But it's full of
XML markup. It's hard to do something useful with it, like create a
file list. (About all it is good for is Visual Studio IDE and
MSBuild).

I think you can simply add cryptlib.vcxproj to your project.

You don't need the other projects: cryptest.vcxproj, cryptdll.vcxproj
or dlltest.vcxproj.

Also see https://www.cryptopp.com/wiki/Visual_Studio on the wiki.

Yeah, that's a problem when you are unfamiliar with a library. I've
been trying to update the wiki samples that include the headers.

If you find a gap in the wiki, then please point it out. I'm thinking
we may be missing an example of integrating cryptlib.vcxproj into a
user's project. There's an old article I wrote years ago, but it is
really old: https://www.codeproject.com/Articles/16388/Compiling-and-Integrating-Crypto-into-the-Microsof
