i have downloaded boost_1_42_0,zip but i'm not sure how to set it up. does http://www.boostpro.com/download/boost_1_42_setup.exe has to do something with it?
If you are only going to use header only libraries in Boost then all you need to do is extract the source archive and add an include path to your project to the Boost root location. There's a, possibly not up to date, list of which libs need to be compiled in the Getting Started docs (see Section #3). If you do need to compile things you can follow the instructions in the Getting Started (see 5.2 and/or 5.3). The BoostPro installer is done independently and hence isn't always up to date, although Dave A. And Daniel W. do try to keep it current. But since there's a limit to how many configurations they can account for it has limits as to having the kind of binary you will need, and of course it's only for Visual Studio.
IIRC, the boostpro setup is an alternative way to get Boost running on your system. It is smallish program that starts by asking you which libraries and configurations you want, and then downloads the necessary files on the fly. It is much easier and faster to get going this way than by building from source, but it isn't always up to date, particularly just after a new source release, and only supports Microsoft's compilers, AFAIK.

before I explain my current problem with Visual Studio in combination with CMake, I try to explain what I want to accomplish as there might be a better solution.
At our company we have a huge code base mainly written in C for QNX. For development we are using the standard IDE QNX momentics. As this is based on a quite old eclipse version ... the whole IDE sucks.
I'm currently evaluating to use Visual Studio as a replacement. With a really simple HelloWorld-programm I was able to build and debug the project from within VS using CMake and a CMakeSettings.json.
As our code base is basically organized in a tree-like structure, I've created a typical hierarchy of CMakeLists.txt which allows me to build single/multiple projects.
As QNX delivers its own compiler I've created a toolchain file, this is running fine so far, the required toolchain is invoked once a build is triggered via cmake.
Now for the part that I'm struggling with:
How to use this CMake setup in order to develop/debug code from VS?
I had two ideas in mind which don't really work or I'm doing something wrong.
Use the CMake generator for VS 2019 and generate a complete solution. Problem: The toolchain file is not "used" as all projects will be setup with the internal VS compilers. Is there any way to get this working? I thought calling cmake -G "Visual Studio 16 2019" -DCMAKE_TOOLCHAIN_FILE=$FILE would do the job. Additionally: how would I incorporate the debugger configuration? With this solution the CMakeSettings.json seems to be ignored as VS solutions are used.
Use File->Open->CMake to open the root project. Shouldn't this show all "contained" projects which also include a CMakeLists.txt as projects? I can only see the folder tree in the Solution Explorer. Build a single project from the solution explorer is also not possible ... there is simply no option.
Anyone with experience on this topic?
Minor comment please limit questions to 1 question in the future. Multiple questions clutters questions and makes search results worse.
============================================================
I'll answer question #1 this part of question number 1.
"Use the CMake generator for VS 2019 and generate a complete solution. Problem: The toolchain file is not "used" as all projects will be setup with the internal VS compilers. Is there any way to get this working? I thought calling cmake -G "Visual Studio 16 2019" -DCMAKE_TOOLCHAIN_FILE=$FILE would do the job."
Instead of using Visual Studio as your generator try using "Ninja" instead. Ninja will work if your toolchain code is correct. Toolchains and visual studio are complicated to say the least. If you wanna go down that rabbit hole I can help but that's a separate question
Basically try switching to Ninja instead of Visual Studio as your generator for CMakeSettings.json. Ninja is very easy to write toolchains for.

"Additionally: how would I incorporate the debugger configuration?"
The MSDN articles are actually quite good. I figured it out this week. In my opinion the debugger configurations are more powerful with the CMake approach than vanilla visual studio.

Trust me once it clicks you'll love it.
I've downloaded the binary for Windows (here: http://llvm.org/builds/), but this doesn't include any of the files, e.g., "llvm/IRReader/IRReader.h", that many tutorials use.
Now, I've downloaded the LLVM source (here: http://releases.llvm.org/download.html), but instructing Visual Studio to look up include files in "include/llvm" results in lots of errors: header files cannot be opened, because they have a cmake suffix.
How do I get up and running fast without too much configuration?
You will need to run CMake before you can do anything. That will create Visual Studio solution files, which you can then use the build the LLVM binary files from sources. Only after you have build the binary files, you will be able to develop further applications linking to LLVM.
There is a platform independent guide here, also there used to be a windows specific guide too, which I could look for later.
http://llvm.org/docs/CMake.html
For a first-time user of CMake I would recommend CMake-GUI, as it is much less of a hassle to use.
I think for starters one can use default settings. Just make sure to select the correct Version of Visual Studio, otherwise you might end up with incompatible solution files
I am creating a very large project (a few thousand lines) and so would rather not use Notepad++. An IDE would make it so much easier. I have experience with Microsoft Visual Studio and love it. Is there some easy way to use Cygwin's GCC from within Microsoft Visual Studio?
Alternately, are there any other good Windows IDEs for GCC besides NetBeans and Eclipse? (I hate both of them with a passion.)
There are several ways to go here:
Option 1: Create a Custom Build Tool
Visual Studio 2005 and newer will let you register custom build tools. They tell the IDE how to transform files of one form (e.g. a .cpp file) into another form (e.g. an .obj file).
So far as I know, no one has done this yet for GCC. And, doing it yourself requires writing COM code, which is probably too deep a pool to dive into just for a single project. You'd have to have a compelling reason to take this project on.
You then have to manually adjust each project to tell it to use the custom build tool instead of the default, since you're using a file name extension (.cpp, probably) that Visual C++ already knows about. You'll run into trouble if you try to mix the VC++ and g++ compilers for a single executable built from multiple modules.
On the plus side, if you were looking to start an open source project, this sounds like a good one to me. I expect you'd quickly gather a big user base.
Option 2: Makefile Project
Start Visual Studio and say File > New Project.
In the Visual C++ section, select Makefile Project
Fill out the Makefile Project Wizard:
Build command line: make
Clean commands: make clean
Rebuild command line: make clean all
You can leave the Output (for debugging) field alone if you've named your executable after the project name and it lands where Visual Studio expects to find it.
Leave the rest of the fields alone unless you know what they are and why you want to change them. As an example, you might choose to pass a -D flag on the Preprocessor definitions line to get separate debug and release outputs. If you know you want this, you know how to set it up, so I'm not going to make this long answer even longer in order to explain it.
You'll be asked the same set of questions for the Release build. If you want to bother with separate debug and release builds, you'd make any changes here.
Having done all this, you still have to create the Makefile, and add a make.exe to your PATH. As with the debug vs. release question, going into that level of detail would push this answer off topic.
As ugly as this looks, it's still easier than creating custom build tools. Plus, you say you need to port to Unix eventually, so you're going to need that Makefile anyway.
Option 3: Cross-Platform Development
You say you want to port this program to Unix at some point, but that doesn't mean you must use GCC on Windows now. It is quite possible to write your program so that it builds under Visual C++ on Windows and GCC/Makefiles on *ix systems.
There are several tools that make this easier. One very popular option is CMake, which is available as an installation time option in newer versions of Visual Studio. There are many alternatives such as SCons and Bakefile.
Clang
You can use the Clang compiler with Visual Studio to target Android, iOS, and Windows.
If you are targeting Android, you can use the Clang/LLVM compiler that ships with the Android NDK and toolchain to build your project. Likewise, Visual Studio can use Clang running on a Mac to build projects targeting iOS. Support for Android and iOS is included in the “Mobile Development with C++” workload. For more information about targeting Android or iOS check out our posts tagged with the keywords “Android” and “iOS”.
If you are targeting Windows, you have a few options:
Use Clang/LLVM; “Clang for Windows” includes instructions to install Clang/LLVM as a platform toolset in Visual Studio.
Use Clang to target Windows with Clang/C2 (Clang frontend with Microsoft Code Generation).
GCC
If your project targets Linux or Android, you can consider using GCC. Visual Studio’s C++ Android development natively supports building your projects with the GCC that ships with the Android NDK, just like it does for Clang. You can also target Linux – either remotely or locally with the Windows Subsystem for Linux – with GCC.
Check out our post on Visual C++ for Linux Development for much more info about how to use Visual Studio to target Linux with GCC. If you are specifically interested in targeting WSL locally, check out Targeting WSL from Visual Studio.

I'm from the future.
I keep (poking at) a C/C++ toolchain using Visual Code on Win/Lin/Mac and MinGW installed from Choclatey.
(This was done for my sanity - install GDB and GCC however you want)
I've run it with GCC and GDB with IntelliSense using MS's own weird JSON makefiles.
Someday, someone (you?) will write a Gradle or Python script to generate these; for now the examples online in the docs seem to work.
It seems to require three types of JSON thing;
a single IntelliSense configuration for the whole workspace
a Debugging Configuration entry for each binary you want to debug
these can invoke the build tasks
a Build Task per-artifact
I don't think that there's a "require" or "dependency" thingie-mah-bob; sorry
I am using Matlab 2010 and VS2010.
I have the Matlab Compiler Runtime installed in my system.
Whenever if run command mcc -setup I get only one compiler lcc. This compiler gives a lot of errors when used to build a C++ shared library using deployment tool. It builds only C Shared libraries correctly.
Can I also connect VC++ compiler with MCC ????
How should I do that ??
Have you read this article? Especially note 2? They are talking about a similar bug there.
PS
Matlab interacts with compilers using mexopts files, located in
matlabroot\bin\win64\mexopts\
So, you may add virtually any compiler yourself.
Some mexopts are available through Mathworks fileexchange.
If you've got access to newer matlab installation, you can get mexopts from there.
You can write your own set of mexopts, based on existing files. In genereal, it's rather easy make, say VS2010 mexopts out of VS2008 ones.
Here's an official article on this.
There is an issue with Matlab 2010 and VS2010. It seems like Matlab was released before VS and therefore it does not have automatic way of configuring VS2010.
I ran into this issue once and my best advice is to download VS2008 express edition...
It's lame, but its the quickest way to get Matlab 2010 working with VS.
Sorry.
I work on C/C++ using Visual Studio 2008. I believe that I am not concerned about which runtime libraries are being used by my code as I have the developer setup. But when the executable is shipped, the runtime libraries being used need to be shipped alongwith. Am I right?
If yes, how can I identify which shared libraries are actually getting used? Or are there any libraries that we can ship without having to know this?
You're correct, you need to ship a version of the C runtime libraries that matches the version you linked your application against. If you're compiling with Visual Studio 2008, then you want to use the Microsoft Visual C++ 2008 Redistributable Package. As other folks mentioned, you can inspect your application's manifest file to see exactly which version of the C runtime libraries it's linked against.
Before shipping, it's always best to install your product on a clean (i.e., non-developer) virtual machine and run Microsoft's Dependency Walker utility to verify that your application uses the correct C runtime libraries.
you need to ship dll files with you.
you can guess most of them and for the rest you can use a program "Dependency Walker" which shows you dependencies of the executable.
Look at the generated manifest file to see which version of the CRT you need to ship with. It's possible to change which version of the CRT you link to as seen here but it doesn't seem to be recommended.
