I'm trying to compile a application developed under Linux Debian for Windows 10 using the mingw compiler and cmake.
I configured a toolchain file according to the tutorial from kitware . This works great as long as I have no dependencies to libraries. Following the tutorial I have to install the libraries in the second path of this line:
SET(CMAKE_FIND_ROOT_PATH /usr/i586-mingw32msvc /home/<USER>/mingw-install )
I tried to download the library sources (e.g. for Termcap) but I have not really an idea how to install the library under the path /home/<USER>/mingw-install using MinGW.
Could somebody give a example for Termcap what commands I have to invoke or a link to a tutorial?

I installed WINE (for testing and debugging the binaries without the need for Windows) and MinGW on a Linux for cross-compiling purposes, but when I try to compile anything that requires curses, MinGW complains that it cannot find the header file "curses.h". So, I believe a good solution would be to install pdcurses, but how come? And after installed, how to link it to a program being compiled? I mean: for some reason, MinGW can't find pdcurses.
I am developing a software in C++ on windows 32-bit (using MSVC++), but since I want to be able to use my software on every platform, I have decided to use CMake as my build generator.
Therefore, I am still just a beginner in CMake. From the CMake tutorials, I understand that in order to cross compile codes, first a toolchain simulating the target platform should be installed on the host platform. Then using the appropriate target-platform C and C++ compilers provided by this toolchain, CMake would be able to generate makefiles etc.
Now, I want to build my code for Linux platform(GNU/Linux) on a Win32 platform. I tried doing the above procedure using CMake combined with Cygwin and using gcc and g++ as compilers. It built fine, created makefiles, and when I issued "make" in Cygwin terminal, the generated makefiles were "made". Now I have got an executable which I was hoping would run on Linux platform. But on Linux I get the error: bash cannot execute binary file.
Using command file executablename, I realized the executable which is made by the above procedure is of type PE32 which is only for Windows.
Now my question is: Is my understanding of cross-platform build procedure using cmake correct?Or should I just use another Linux toolchain under windows to get a Linux ELF executable? What toolchains come to your mind which would give me what I want?
Many thanks

You will want to look here: cmake-toolchains(7) if you do cross compiling. However, I would suggest that you install a Linux VM like virtual box on your windows machine and build naively on Linux. It will compile much faster and you will not have to worry about cross compiling. You can mount the windows disk from the linux VM so you can share the same source tree. The linux VM will compile much faster than gcc running under windows.
Your understanding of CMake is correct... it will determine how to create the build system you request (or is default for the platform you are currently on) based on rules in your CMakeLists.txt file. However, this won't necessarily help you compile for linux on a windows machine if you don't have something installed that can target linux.
To compile targeting linux, you will need to use a linux compiler. The link posted by #stjin tells you how to install one on cygwin. Then, to set up your CMake build, do this in the terminal:
CC=gcc-linux CXX=g++-linux cmake . [options]
This will tell CMake to locate the special linux targeted compilers. Hopefuly, after compiling with these compilers you will be able to run on linux.
I'm trying to get GSL working in a windows environment for my team and I'm running into many problems.
My team develops in C++ in VS2005, and we'd like to use GSL. I've downloaded the GSL-1.15 tar.gz, and unzipped it, but i'm not really sure what to do from here - I believe only two compilers will build it properly.
On the GNU website, it says that a compiled version of GSL is available as part of Cygwin on windows, so I installed Cygwin, but again, I'm not really sure what to do from there.
Ideally, what I'm trying to get is a folder on my C:\ with a bunch of dll / libs that I can link to in VS2005 to use the GSL functions. I'm aware of GSL ports to VS (http://gladman.plushost.co.uk/oldsite/computing/gnu_scientific_library.php), but we can't rely on them as I would be dependent on the publisher releasing a port every time a new version of GSL is released.
Has anyone successfully gone through this process of building GSL and getting it to work with C++ in VS2005? I've done some google searches and haven't found anything that I understand.
Thank you.
With Cygwin
Install one or more of the GSL packages
gsl
gsl-apps
gsl-devel
gsl-doc
With MinGW
I have personally built GSL with MinGW using this incantation
wget ftp.gnu.org/gnu/gsl/gsl-1.15.tar.gz
tar xf gsl*
cd gsl*
./configure
# Warning, make takes about 7 min.
make
make install

Will I have to use the crosstool that cygwin provides to make the libX11.so, libGL.so, and libGLU.so libraries using their respective source code? Or do you know where I can find them compiled already for crosstool (I'm new to this cross compilation)?
Just for clarification: I'm on a windows 7 machine trying to get my application also to compile for linux systems by using cygwin's cross compilation. The application uses OpenGL. Thanks
To cross-compile for Linux you should install the needed development libs and headers on a linux box[1] and then copy /usr/lib and /usr/include your cygwin environment (e.g. /crosscompiler/linux/...). When you build the cross compiler in cygwin, tell it where those native linux headers and libs are so they'll be used when you compile your app.
[1] If you're looking to run on a wide variety of linux boxes make sure you pick an older linux distro (e.g. Red Hat 9) to ensure your app doesn't have dependencies on very new glibc, etc..
Why do you want to use Cygwin?
There is instructions on the OpenGL Wiki about how to use OpenGL on Windows using MinGW.
MinGW use the same GNU tools that are available on Linux (GCC, GDB, GMAKE, etc.) but produce Windows native executables. So, you shouldn't have trouble compiling your source code on both platforms.
I just ended up building on a native Linux machine.
I need to cross compile my QT application in Linux. I compiled my application from the QT SDK in Linux and it is working properly.
How do I create an .exe for the same application in Linux. I have installed Mingw in Linux and qmake, but I dont know how to proceed with cross compiling.
How do I link my QT with a cross compiler like MinGW and Qmake. I am using SuSE Linux. I have also gone through http://Silmore/29 but I am not getting a clear picture of how to proceed futher.
I'm not familiar with SuSE, but Ubuntu has the mingw32 packages which is a windows targetted cross compiler, along with the open source win32api:
(source: liranuna.com)
After a small search, turns out there are RPMs for it here, while it should probably be in your repositories.
Basically, you use your cross-toolchain for the Make process rather than the host toolchain. I assume there is no autotools configure script. If there is you can run configure with --host specified and have it all figured out for you.
So what you'll need to do is set CC, LD, CFLAGs, LDFLAGS (probably also CXX and CXXFLAGS) and modify the Makefile to use the right QT libraries - which will need to be mingw, not your Linux libraries. So you may also need to obtain the MinGW/Windows QT SDK and store it separately so your paths cam be specified properly.
Hope this helps!
You could run the Visual C++ Express Edition 2008 cl.exe through wine to compile your project.
