I am trying to build OpenBLAS from here, following these instructions. After running
cmake .. -G "Ninja" -DCMAKE_CXX_COMPILER=clang-cl -DCMAKE_C_COMPILER=clang-cl -DCMAKE_Fortran_COMPILER=flang -DBUILD_WITHOUT_LAPACK=no -DNOFORTRAN=0 -DDYNAMIC_ARCH=ON -DCMAKE_BUILD_TYPE=Release -DBUILD_SHARED_LIBS=ON
The error generated is:
-- The C compiler identification is unknown
-- The ASM compiler identification is unknown
-- Didn't find assembler
CMake Error at CMakeLists.txt:6 (project):
The CMAKE_C_COMPILER:
clang-cl
is not a full path and was not found in the PATH.
Tell CMake where to find the compiler by setting either the environment
variable "CC" or the CMake cache entry CMAKE_C_COMPILER to the full path to
the compiler, or to the compiler name if it is in the PATH.

After a bit of googling, I found this webpage: Assembler
It does not specify how to resolve this issue. How to solve it?

When building with cmake on windows using Mingw64 we get errors like:

How to fix it?
This happens because cmake uses the Microsoft CMake format as default. The CMAKE_CXX_COMPILER not set here also indicates that we need to set the CMAKE_CXX_COMPILER variable to a c++ compiler path.
To fix we need to use the following command:
cmake -DCMAKE_CXX_COMPILER=g++ -DCMAKE_CC_COMPILER=gcc -DCMAKE_MAKE_PROGRAM=mingw32-make -G "MinGW Makefiles" ..
Here we provide the following flags:
CMAKE_CXX_COMPILER=g++ - Use g++ as C++ compiler (or provide full path)
CMAKE_CC_COMPILER=gcc - Use gcc as C compiler
CMAKE_MAKE_PROGRAM=mingw32-make - Use mingw32-make as the make program
-G "MinGW Makefiles" - Use the MinGW Makefile format not Microsoft makefile format
After this you can run mingw32-make as usual instead of make to build :)
I'm running a conda environment on Windows to get a bash-similar environment (I'm a native Linux Mint user and this is my first time running Windows). But when I run cmake in my conda environment I get the following error:
-- Building for: NMake Makefiles

CMake Error at CMakeLists.txt:33 (project):
The CMAKE_C_COMPILER:
cl

To use the NMake generator with Visual C++, cmake must be run from a shell
that can use the compiler cl from the command line. This environment is
unable to invoke the cl compiler. To fix this problem, run cmake from the
Visual Studio Command Prompt (vcvarsall.bat).
Tell CMake where to find the compiler by setting either the environment

the compiler, or to the compiler name if it is in the PATH.

I've installed GCC on my conda environment, but I'm not sure how to force CMake to find it.
UPDATE:
I was able to point the compiler to where gcc is installed, but now I get this error:

For the record I am using:
gcc and g++ from MinGW 4.8.1
CMake 3.4.1
I have no idea what the issue could be, I've looked extensively online and have not found anywhere where somebody has gotten a solution, except in cases where it had to do with path issues where the path included non-latin characters or no write access, which is not the case for any of the directories in question. I seriously am about to give up completely on ever being able to get this to work, but I don't know what to do because I absolutely NEED the socket.io client for C++ for this project.
CMake is a utility which generates a "makefile" for different build systems. Here you generate a nmake makefile and it seems that you don't have nmake in your path.
You can launch CMake with option -G "MinGW Makefiles" in order to generate a makefile compatible with mingw make. Then issue the command:
mingw32-make
On Windows 10, with an installed msys2, which is a variant of mingw, I have an installed cmake with the gcc toolchain and all the standard tools like make.
The version of g++ is 6.2 and make is 4.2.1 Both are in the path.
When I build using cmake:
cmake .
it tries to build using nmake and cl. So somehow because I am on windows cmake is trying to use the visual studio toolchain.
export CMAKE_CXX_COMPILER=g++
does not help. The error is:

To use MSYS2 toolchain, you need to specify the build system generator explicitly, i.e.
cmake -G 'MSYS Makefiles' .
Additional note, it's a good practice to separate the application . source file and cmake's generated file, e.g.
mkdir build
cd build
cmake -G 'MSYS Makefiles' ..
I'm trying to build OpenCV 3.0.0 on a Raspberry Pi 2 running Raspbian Jessie. After installing all dependencies, I tried running cmake with the following parameters: cmake -D CMAKE_C_COMPILER=/usr/bin/gcc -D CMAKE_CXX_COMPILER=/usr/bin/c++ -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local ..
But then I got the following error.

Any suggestions?
It's not actually a solution, but I reinstalled my Raspberry Pi again, but this time with the older Raspbian version "Wheezy". On Wheezy, everything worked fine. So I guess there's a problem with Raspbian "Jessie" with OpenCV and/or cmake.
