I'm trying to compile OpenCV with Cmake on Windows 7 (64-bit). It is to be used with Eclipse and CDT, for which I read somewhere that youhave to specify Unix Makefiles regardless of the compiler.
Now, given that I have cygwin as well (for Android NDK stuff), I first tried using its compilers, and I successfully configure CMake and generate makefiles, but only get to 63% of compiling, when OpenCV spits an error (about ffmpeg and HMODULE). So I switched to MinGW (HelloWorld with it was also a pain, I had to specify a full path to MinGW g++ regardless of the PATH variable setting), but now I cannot even configure CMake. I get the following error:
The C compiler identification is GNU
The CXX compiler identification is GNU

If anyone has any idea what might be a problem (conflict with cygwin shell?), I'd appreciate any input. Thanks in advance!
We ran into the same problem with the "Unix Makefiles" Generator. We solved it by using the "MSYS Makefiles" generator (Msys is a shell environment around MinGW, like [a very small] cygwin).
This error message text:

indicates that "windres" (for mingw and cygwin gcc-based build trees) is not in the PATH.
windres support, to compile Windows resource (*.rc) files was recently added in CMake 2.8.4. Perhaps windres is not available in your MinGW environment?

I was configuring Clion by following a guide here on StackOverflow, but I have a problem. The section about make, C compiler, and C++ compiler have some problems, but I don't understand what I should do.
Notice the "Test CMake run finished with error" message. When I click on "more...", I see this:

What should I do?
I'm trying to do a simple compilation with mingw-w64 and cmake. But for some reason I can't. It fails verifying if gcc can compile a C program which is weird. Any ideas?

You can provide another make command using CMAKE_MAKE_PROGRAM, like for instance:

However the gcc compiler is in C:/MinGW/bin/ and it works.
Any idea?
Platform:
Windows 7
MinGW/GCC 4.6
Never try to set the compiler in the CMakeLists.txt file.
See the CMake FAQ about how to use a different compiler:
https://gitlab.kitware.com/cmake/community/wikis/FAQ#how-do-i-use-a-different-compiler
(Note that you are attempting method #3 and the FAQ says "(avoid)"...)
We recommend avoiding the "in the CMakeLists" technique because there are problems with it when a different compiler was used for a first configure, and then the CMakeLists file changes to try setting a different compiler... And because the intent of a CMakeLists file should be to work with multiple compilers, according to the preference of the developer running CMake.
The best method is to set the environment variables CC and CXX before calling CMake for the very first time in a build tree.
After CMake detects what compilers to use, it saves them in the CMakeCache.txt file so that it can still generate proper build systems even if those variables disappear from the environment...
If you ever need to change compilers, you need to start with a fresh build tree.
I had similar problem as Pietro,
I am on Window 10 and using "Git Bash".
I tried to execute >>cmake -G "MinGW Makefiles", but I got the same error as Pietro.
Then, I tried >>cmake -G "MSYS Makefiles", but realized that I need to set my environment correctly.
Make sure set a path to C:\MinGW\msys\1.0\bin and check if you have gcc.exe there. If gcc.exe is not there then you have to run C:/MinGW/bin/mingw-get.exe and install gcc from MSYS.
After that it works fine for me
Using with FILEPATH option might work:
set(CMAKE_CXX_COMPILER:FILEPATH C:/MinGW/bin/gcc.exe)
I had the same issue. And in my case the fix was pretty simple. The trick is to simply add the ".exe" to your compilers path. So, instead of :
SET(CMAKE_C_COMPILER C:/MinGW/bin/gcc)
It should be
SET(CMAKE_C_COMPILER C:/MinGW/bin/gcc.exe)
The same applies for g++.
I am currently trying to get CMake to run on my Windows 7 (64-bit) system. I want to compile TagLib for later use with a Qt application I am working on. I would like to compile it with MinGW (not Visual C++ as in this other question).
I download the installer (cmake-2.8.3-win32-x86.exe) and install it (I also opt to add CMake to my path). I then go to the directory why the CMakeLists.txt file is and run cmake .. It then gives me this giant error.

I was kind of surprised that it failed so hard out of the box, considering it advertises itself as a cross-platform make.
I tried setting INCLUDE, LIB, and LIBPATH (Windows environment variables) all to my MinGW binaries directory (C:\MinGW\bin) but it's still giving me the same error. I also tried setting CMAKE_C_COMPILER and CMAKE_CXX_COMPILER to the location of g++ (C:\MinGW\bin\g++).
Does anyone know what's going on here?
SOLUTION:
Per tibur's suggestion, I ran the cmake GUI to create the make files.
I then went into the directory taglib directory and ran mingw32-make.exe to do the actual build.
The default generator for Windows seems to be set to NMAKE. Try to use:
cmake -G "MinGW Makefiles"
Or use the GUI, and select MinGW Makefiles when prompted for a generator. Don't forget to cleanup the directory where you tried to run CMake, or delete the cache in the GUI. Otherwise, it will try again with NMAKE.
There is a vcvars32.bat in your Visual Studio installation directory. You can add call cmd.exe at the end of that batch program and launch it. From that shell you can use CMake or cmake-gui and cl.exe would be known to CMake.
the command that worked for me is:
$ cmake -G "MSYS Makefiles" ..
I'm working on MSYS2/Win10 compiling a QT5 app #64bit (using the MINGW64 shell)
Use: cmake --build
after cmake -G "MinGW Makefiles"
I'm new with cmake,just installed it and following this article:

What are the complete requirement to use cmake successfully in windows XP?I've already installed Visual Studio under D:\Tools\Microsoft Visual Studio 9.0
First of all, I have to confess that I don't know cmake.
To use the NMake generator, cmake
must be run from a shell that can use
the compiler cl from the command
line. This environment does not
contain INCLUDE, LIB, or LIBPATH,
and these must be set for the cl
compiler to work.
The error above means that the proper locations to your C/C++ compiler's headers and libraries could not be found by cmake.
Instead of running cmake from the Command Prompt, try running cmake from the Visual Studio 2008 Command Prompt. You can find it under Start > Programs > Microsoft Visual Studio 2008 > Visual Studio Tools) or vcvarsall.bat in the folder *Microsoft Visual Studio 9.0\VC*. The visual Studio 2008 Command Prompt should set all these environment variables for you automatically so that cmake knows where to find the necessary files that it needs.
The Command Prompt will start in your Visual Studio folder, so you'll have to type the following commands to switch to your source folder and start cmake.
D:
cd D:\Works\c\cmake\build>
cmake
I hope this helps you.
I had similar issues on Win7, and was getting the same error - The C compiler "cl.exe" is not able to compile a simple test program.
The solution that worked for me :
On Windows Donot run cmake on the cygwin terminal.
Run it from the command prompt, AND also ensure that you have admin rights, In windows 7 you can start command prompt as administrator by going to Start->All programs->Accessories-> (Right Click on Command Prompt) and Select "Run as administrator"
Then run 'cmake <your source>' Worked like a charm for me.
