Is there possibility to compile windows service using only mingw c++ compiler and library?
I assume that it is possible to use compiler with Visual Studio standard library and means, but want to do to this almost fully opensourced.
Any experience?
Since you can build programs with the Windows Platform SDK (or whatever it's called today) using MinGW, you can build Win32 services.
Services are just Win32 programs with some specific protocols used to register them with the system and interact with the operating system's service controller.

I’ve got an app that creates a child process to execute via CLI a compiled C++ library file. What is the best/most portable way of shipping my app with this library? I just need to ensure the compiled C++ code is available on the user’s system and that the executable is compatible with their system.
C++ is compiled for each platform (Windows, macOs, Linux). So you need three different distributions:
Windows - lowest common version (for example Windows 7). You also need to require or include the C++ redistributable for the compiled library.
Linux - most use gcc, so again the lowest common version. No redistributable required.
macOs is similar to Linux.
Each platform supports multiple compilers and IDEs. It’s down to personal choice.
We're moving to Visual Studio 2017 and VS2017 prompts us to retarget the projects for 2 things: Windows SDK Version and Platform Toolset.
Currently our application can run on older Windows versions (at least to Server 2003, possibly older), and we need to retain the same (I know they're not supported anymore, but that's the customer's requirement).
Assuming that our code (which is all C++ in case it makes a difference) does not use any APIs which are only available on newer versions of Windows, will re-targeting to a newer version of the Windows SDK restrict or limit the versions of Windows that our app will run on?
And while on the subject, will re-targeting to a newer version of the Windows SDK have any pros or cons (ex. performance) (again, assuming we don't use any of the new APIs that are only available on newer Windows)?
No, using a newer SDK allows use of newer funcntionality but it does not require doing so. So long as you are careful to only use functionality that is present on the version of windows you are interested in your program will continue to work. You will, however, likely need to install the vs2017 runtime on the client systems.
You will need the VC++ runtime for the development kit that you are building from. Statically linking this library will remove this requirement, as the runtime is embedded in your binary.
I have around of 4 years experience in C#.Net programming and i am developing a client server application. The server application will be insalled on CentOS and client application will be installed in Windows OS. But, i don't have much knowledge about c++ programming on linux platform. So, my question is that can i create a console application in Windows OS and compile it for linux platform. it is not necessary that compile it on Windows. but, it should be executed in linux platform. I am new in linux programming.
Presently i am using TC++ editor. Can i use Visual Studio 2010 to build server application for linux platform?
if there are another approach then please suggest me.
Thanks.
You can develop the client in C# and the server in C++, if you prefer. Consider that unlike C#, there is no standard socket library yet, and you'll have to rely on either system calls or their higher level wrappers (like boost).
I've to tell you that Windows uses BSD sockets (its own version, with some modifications though), therefore with a few preprocessors checks, you can make your application portable.
In your case, I'd suggest you to go for boost.asio which will hide all low-level stuff for you. It's even cross-platform.
Maybe you can use VS as an editor ; Make sure that you do not include any windows specific libs; There is an option of using cygwin and doing a cross compilation. Check the links
How to cross compile from windows g++ cygwin to get linux executable file
I guess it will be more of a pain. Better use Virtual Box --> linuxMint/Ubuntu + Eclipse with C++ plugin or some other C++ editor...
I've got new task to research the way of development C++ cross platform (Mac/Win) utility for our internal needs.
I've developed for 7 years using different "pink" languages like C# , Java , Managed C++.
But in this task , the requirement is to support Mac , and .NET that is running on Mac , is really pain (Know this from other guys who did used this).
So I've started to think about C++ if it's possible to use C++ for Cross platform development.
The application will no contain any GUI , but will contain a lot of System API calls , and a lot of business logic analysis.
Is there possible some library allowing to achieve such kind of Task ?
Is it possible to do at all ?
Yes, you can write standard, ISO C++ and run the programs on both platforms.
When you need to implement some functionality using platform specific APIs (e.g. using Win32 on Windows and POSIX APIs on Mac OS) then what you do is write your own wrapper functions that abstract away the platform specific details, and then use that wrapper in the rest of your program.
Tools like CMake will allow you use Visual Studio to build the program on Windows and Xcode to build on the Mac without having to manually manage separate Visual Studio and Xcode project files.
If I understand your question properly, the only thing you need to develop cross platform c++ is to get the right compilers. You could use GCC on both platforms or even use 2 different project files for visual studio and xcode. That's up to you. Personally, I prefer GCC.
Regarding code itself, it depends on what you do with it. STD is available on both platforms (std::vector, std::string, etc) so code should compile properly on both platforms.
Edit: Btw, most platform specific stuff are available through open source code (like boost though I personally don't like boost that much). If needed, you could even look at other open source projects that are cross platform (ogre3d, etc).
I would like to develop C++ on Windows because I prefer the Visual Studio IDE (eclipse on Linux isn't very nice). However, eventually I will migrate to Linux and some of the code I will be writing will use low-level OS system calls.
Is there any way I can install a Linux emulator (not sure what you call it) on Windows, write Linux system calls in Visual Studio 2012 and have these system calls target the emulator, rather than the Windows OS?
I have tagged VS2010 but I can use VS2012 also.
Windows OS is Win 7.
You've already tagged your question with Cygwin. That seems like the best solution for what you want. Cygwin is basically a collection of programs which emulate a GNU/LInux environment through the use of a
DLL (cygwin1.dll) which acts as a Linux API layer providing
substantial Linux API functionality.
Here's the link to the documentation for its API
Edit: Most of the Cygwin source code that I've looked at is written in C++ and makes system calls using MS Windows API to do provide the *nix emulation. The source is well written and very readable (even to to a non-C++ programmer such as myself). I think using Cygwin would be a good transition from programming on Windows to a GNU/Linux environment.
