How do I build it? The documentation is really shady about this. It says you need to place scons.py into the directory, but I have no idea where this is. I have tried using the included prebuild, but it did not produce any .lib files.
No need to use scons.
After you download the jsoncpp source, like from https://github.com/mrtazz/json-cpp, unzip the sources. In this unzipped source tree, under /makefiles/vc71/ you will find several Visual Studio project files which you can up convert and build.
There is a visual studio solution file under makefiles. Did you try migrating that to VS2010 to see if it works?
.py? This is a python script, and has nothing to do with C++. Perhaps you are looking at the wrong instructions.

I know cmake is a tool which can produce visual studio solution files from source files. I see many of c++ projects are stored in the github in that way. My problem is how create that source. Is there anyway to generate it on visual studio or anyother way.? I have created a project by using visual studio . So I have the solution file. I want to upload it in to github as a portable source which can produce project files later using cmake for anyone.
Probably my question is a stupid question made by a newbie programmer but I'm stuck and don't know how to fix it.
I downloaded a project and tried to compile it. But it gives a LNK1104 cannot open file VirtuosoConsole.lib error, which I know a lib is missing but i don't know if I must compile it from source files or what I have to do. In case I have to build it, what I have to do to do it?
Thx for the help.
I'm using Visual Studio 2015 community.
The cmake project should create the VirtuosoConsole library.
It is a cmake project, so you need to have cmake installed and run cmake on the project to generate the make files for visual studio to use.
I've been trying to get curl linked to my project in Visual Studio 2013 and C++, however all tutorials online reference files that are not available anywhere in the archives you can download from their website. What I did was I went to http://curl.haxx.se/latest.cgi?curl=win32-ssl-devel-msvc and downloaded the package. All tutorials reference either a lib/Debug folder or some .dll or .lib files which just simply aren't there. The documentation on their website is from 2002, so that won't help either.
Could anyone explain which version I need to download and what I need to reference in my project properties and where? Thanks!
Ok fixed it, had to build the libcurl.lib file from source. Changed build type to LIB Release and it worked! Thanks.
I downloaded cpptest from internet, and I want to build it using Visual Studio 2008.
The problem is that instead of .sln and vcproj file, Makefile.am is distributed, and I believe that all the all the necessary included file is included in the Makefile.am.
How to use Makefile.am to generate VS project files? I tried to use Cmake, but there is no CMakeList in the distribution.
Edit: Thanks to all the answers! There is a sln file distributed after all. But I am still interested to know the answer to my original question.
the visual studio project files for cpptest are in the win directory, not in the src directory where the makefile is..
edit
makefiles are meant to be used with GNU make. If you want that on windows, you can look at Mingw, GnuWin32 or Cygwin. But they also require gcc for compiling, so you won't really be using VS.
However, for most projects that do not have external dependencies it's no big deal if you do not have the VS project file: after all a makefile is just a list of the source files and some compilation options. To successfully build projects like cpptest, you could just create an emtpy VS project, add all source files to it, set output type to executable, build it and you're done. Eventually you can tune optimization options, but for the rest the default options will just do fine.
Go to win\VisualStudio.NET and you will find a VS solution file.
I just downloaded the archive and found the .sln file. It is under: /win/VisualStudio.NET. You can open that with VS2008 and update it, it should work.
I'm fairly new to C++ and an trying to figure out to use the TagLib library for a project I am working on. I'm working with unmanaged C++ in Visual Studio 2010 on Windows 7 64bit. I've never used an external library before so I'm very confused on how to go about this.
From this blog entry I got the libtaglib.a and taglib.dll files. I ran across this SO question on how to use TagLib, but it deals with QT Creator, not Visual Studio and I'm not knowledgeable enough about the subject to understand what is being said to translate it into what needs done for Visual Studio.
So, some questions:
Is it even possible to do this with unmanaged code?
What exactly is the function of a .a file?
Most importantly, how do I go about using the taglib.dll in my program??
I've been all over Google looking for a way to do this, but my major problem is that everything I run across is over my head. Please let me know if more info is required. Any help is very much appreciated! Thanks!
I seem to have gotten it working successfully. Here's a rough outline of what I did:
1.) I used CMake to generate the Visual Studio solution.
2.) I attempted to build the tag project in the VS solution, but it failed.
3.) I made the corrections to a few source files as outlined here: http://old.nabble.com/taglib-fails-to-compile-with-MS-VC%2B%2B-2010-td29185593.html
4.) I built the tag project again in release mode. This time it was successful.
5.) I copied the resulting dll, def, and lib files to the same directory as the source files for my project.
6.) I copied the header files from the taglib source to a subdirectory in my project (not sure if this entirely good practice)
7.) In my project settings, I set the subdirectory with the header files as an additional include directory.
8.) I added the dll, exp, and lib files to my project by just going to Add>Existing Item.
9.) I added some code from the taglib examples and built it. Everything worked so I think I got it.
One caveat I ran into, since the DLL was built in release mode, my project had to be run in release mode or it would crash. I'm guessing that if I replaced the DLL with one built in debug mode I could run my program in debug mode, but I have not tried this.
You cannot use libraries specific to GCC (you can tell because they have .a extensions) with Visual Studio. You will have to build the library from source in order to use it with MSVC. Once you have done that it's a simple matter of adding the .lib generated from the build process to your project and things should work out of the box. (Note that it's a .lib you need whether you're compiling for dynamic linking or not -- doesn't matter in msvc land)
EDIT -- after looking at TagLib itself --
In order to compile TagLib you'll need to get the CMake build system, and TagLib itself, and have CMake build you a visual studio solution. Using that solution you'll be able to build the .libs and .dlls you need. Note that because TagLib is a KDE library, you'll probably need to also build some QT bits in order for everything work work successfully. However, I don't have specific experience with the library so I'm not going to be all that helpful here.
Yo do not have to recompile the source (to create the .lib file) if you have the .dll file. With dumpbin /exports and lib (both came with Visual Studio) yo can create a lib that you can link with your application. In this link you can see a nice explanation: http://www.coderetard.com/2009/01/21/generate-a-lib-from-a-dll-with-visual-studio/
But as Billy Said, probably you would need other parts of QT to use this library.
