Missing header file of Windows C++ Runtime while cross-compiling - c++

I'm not familiar with this cross-compilation thing, but I do have successfully built wxMSW from Linux before, with the cross-compiler provided by my distro. So, I guess it's okay to say that I have some basic knowledge about cross-compilation. The question is that when cross-compiling, it failed and told me that EventToken.h is missing. According to Eventtoken.h header - Win32 apps | Microsoft Docs, it obviously is one of the header files of Windows' C++ Runtime. I don't have Windows, how and where can I install this header (and very likely some more other headers)? Installing VC++ is obviously not an option, because I don't have Windows at this moment. Thanks in advance. :)

Converting a Linux Library Project into a Library Project usable in windows

I am attempting to convert the ndn library project found at "https://github.com/named-data/ndn-cpp" into something that can be imported into several existing mfc/wpf/forms Visual Studio Projects (building it as .lib or .dll would work).
As a note, it appears to have previously been converted into c# for windows for a older build of ndn, but is no long supported and will not connect with the current ndn network.(https://github.com/named-data/ndn-dot-net)
I have looked into the using the WSL features that they have added to windows 10, and the Visual studio Linux Cross Platform projects, but these all seem to only be able to make .exes that will run in windows not a .lib or .dll that can be imported into another project.
I have also look into the shared items project but what I was able to find didn't seem like it would work for what I'm trying to do.
Lastly, I tried using cygwin. I was able to compile and generate the linux style libraries(.a) on my windows 10 machine, but when i attempted to generate windows style dlls off the .o files(gcc -shared -o mydll.dll mydll.o) I ran into a large number of reference errors that I was unable to resolve.
Does anyone have any recommendations on which of these methods I should be using or if I should be attempting some other method entirely?
Does anyone have any good references or examples of how to do this for someone with limited Linux experience?
Thanks
Ok. I've tried going about this several ways now, and here's what I've learned that might be useful to someone else trying to do this and also where I stand so far:
If you have a simple Linux dll that you have written it's possible to compile it as a Windows dll using MSYS2 or MINGW, instructions are here: http://www.mingw.org/wiki/MSVC_and_MinGW_DLLs
If you have something a bit more complicated like the program I'm trying to convert above, there is no quick fix to convert from Linux to windows, however you still might be able to compile your program for windows using Visual Studio.
Here's how you do it:
Download vcpkg from https://github.com/microsoft/vcpkg This is a linux package manager for windows, it will allow you to download windows equivalents to many common Linux packages (for the above I had to download boost and sqlite3)
Create your own unistd.h, here's a link to that: Is there a replacement for unistd.h for Windows (Visual C)?
Get dirent.h for windows, here's a link to that: https://github.com/tronkko/dirent
replace instances of gmtime with _mkgmtime or redefine gmtime as _mkgmtime: timegm cross platform
This got me about 90% of the way there (and from about 13,000 compiler errors to about 30), The rest of the errors so far have been for calls where there is no easy linux to windows conversion and those sections of code have had to be re-written. (In the code above this would be the socket code for the tcp/udp connections in the tranport files, Linux and Windows handle it pretty differently, boost does have a good guide for how to use it's sockets in windows though: https://www.boost.org/doc/libs/1_60_0/more/getting_started/windows.html)
So that's it. Hopefully this helps someone else down the line. I'll be adding more to this answer as I discover new things.

How to set up Apache Thrift with Eclipse && MinGW in Windows?

I need to configure Thrift for Eclipse project with MinGW compiler. I googled for it. I couldn't find proper instructions to do that? Can somebody suggest any suitable way or proper link to do that?
There are several partial answers to this.
The Windows build is made by means of MinGW cross compiler on a Linux machine.
Since (at least) 0.9.2 it is no longer necessary to use MinGW to build the Thrift compiler on a Windows machine.1) Aside from the fact, that you don't need to do that at all, because a precompiled EXE is available on the download pages, there is a nice Visual Studio project to build the Windows Thrift compiler EXE. The project has only two dependencies: Bison and Lexx/Yacc, which are both available elsewhere as precompiled Setups as well.
In either case MinGW is only used to build the compiler. If you want to build the libraries with MinGW, I'm not sure if that even works. This way of doing things is not implemented or supported, simply because nobody needs it.
Which brings us back to the question, why you think you "need" it this way.
1)To my knowledge, numerous severe problems exist with the autotools and all the stuff needed to build Thrift under MinGW on a Windows machine. You will have to patch things, build some from source, spend a lot of time and do some strange things with your file system to make it work. At least that was the case when I stopped using MinGW to build Thrift about two years ago. And even if you get it to work, you still only get the compiler (which you could easily download in a fraction of that time), not the libraries.

DLL Dependencies with Mingw on Windows

I'm working on a program which uses autotools for its build system and compiles fine on linux. To build for windows I'm trying to get a mingw cross-compiler working for windows. Now when I compile on linux and move to windows of course I am missing some dll's that are not installed by default on windows. This leads to missing dll errors. I cannot statically link my program due to restrictions in the LGPL.
So my question is what is the correct way to cross compile in this situation? I feel like I need to wrap my exe in a installer which automatically resolves and installs the dll dependencies for windows but I haven't been able to locate something explaining how to do this. Basically I'm thinking of yum/apt-get for windows. How do I manage dll dependencies on windows? I'm a linux guy, not a windows guy, so please bear with me.
Probably the easiest thing would be if you could move your development to a Windows machine. But short of that, you could install Windows-Mingw on your Linux machine using Wine. (IIRC winetricks has even a target for this) That way you get a "feel" for the issues on windows. An alternative could be Windows in a virtual machine, but Wine should be ok for a development environment.
I also strongly suggest that you install Microsoft Visual C++. The express versions will do fine. There are a number of tools coming with MSVC++ that can make your life a lot easier, like dll-dependency checker etc. An additional excellent source of information are the Sysinternals tools from Mark Russinovich and his blog.

PSDK Windows Server 2003 R2 MFC support

First I installed PSDK Windows Server 2003 R2 on my x86 machine, there were MFC header files out there. I tried to compile an example MFC application with cl.exe and I got this error message "winmsg_.h header file could not be opened.". I got "winmsg_.h" file from the International Network and put it into the MFC include files library then I again tried to compile the program and got that target platform option conflicts with IA64 platform specific object file. I think that PSDK Windows Server 2003 R2 does not include lib files for x86 machines!
Please help me to solve this problem or suggest me the PSDK that contains the header and lib files for x86 machines! Thanks!
Download SDK from Microsoft Website. It supports both 32 and 64 bit architectures. I'd suggest you to use a make file instead of barely using CL.exe for compilation. You will have to give proper include files to resolve the issues. Which version of the compiler you're using? How you installed it?
Don't go for a third party provided headers. Use the original ones.
I know this is old and people sometimes become upset when you revive a dead post. That said, Google brought me here, and I'm sure many others will be directed this way. This is what I, and I believe you, was/ were looking for:
http://www.codeproject.com/Articles/30439/How-to-compile-MFC-code-in-Visual-C-Express
ATL/MFC headers are not on Platofrm/Windows SDK. Instead, they are shipped with Visual Studio (except Express versions).

how to compile c++ files with cygwin on windows 7

I have installed cygwin. But when I try to compile a c++ file it gives the following error:
/usr/lib/gcc/i686-pc-cygwin/4.3.4/cc1plus.exe: error while loading shared libraries: cygmpfr-1.dll: cannot open shared object file: No such file or directory
I checked in the lib folder there is no library with the name cygmpfr-1.dll. So is it that I have to put that dll in the lib folder. I have tried to search for the dll but could not find this dll so that i can download. I am just a beginner in C++. I have tried to setup cygwin support in netbeans as well, but there also if I try to run the sample files given, it throws the above error.
Can anybody give me a clue?
You need to install the gcc4-g++ package via http://cygwin.com/setup.exe
You only have gcc4 installed.
This will also install your missing dependencies.
If you're a beginner in C/C++, and you're running Windows, then why not take the simple route and get Visual-C++ Express, a free IDE from Microsoft for Windows.
It provides a GUI IDE (Integrated Development Environment), but if you prefer a text editor and command-line tools (compilers, debuggers, etc) those are available to you also, if you install Visual-C++ Express.
There are also tutorials and lessons to get you started.
On the other hand, if you really wanna focus on C++ on Linux, then you should probably uninstall Windows 7 right now.
I have had similar problems and I am no beginner. Try using the cygwin installer, and searching it for all versions of gmp. There generally are 32bit and 64 bit versions. Check everything you see and update your installation. Hope this helps. Some of these dll's you can find on the internet, but not the one you are looking for.
