Question

I want to install dlib using pip install dlib using cmd in windows 10 But it is showing following three errors: CMake Error in CMakeLists.txt: Generator

    NMake Makefiles

  does not support platform specification, but platform

    x64

  was specified.


CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage
CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage

INFORMATION: pip 9.0.1 from d:\python36\lib\site-packages (python 3.6) cmake 0.9.0 windows 10 pro(64-bit) Version: 10.0.16299 Build 16299

Answer 1

I am on windows 10, python 3.5, pip 10
dlib didn't work even after installing cmake. Solution :

• Add cmake into PATH(C:\Program Files\CMake\bin)

• Then install using pip:

  pip install dlib==19.4
  

Works like a charm.

Edit:

After windows October update, the above method works, but sometimes there are errors like boost error and cmake incompatible. so,

• Download and install CMake msi
• Add cmake into PATH(C:\Program Files\CMake\bin)
• Restart Windows

• pip install dlib
  

  or

  pip install dlib==19.4
  

Answer 2

First of all, delete CMakeCache.txt file. Later, just execute inside dlib-xx/build the command below:

cmake -G "NMake Makefiles" ..

If you have more problems with CMAKE_C_COMPILER and CMAKE_CXX_COMPILER, you will have to install MinGW and add to the enviroment variable the path /bin of MinGW.

And if you don't have installed Visual Studio, you would to resolve future problems

Answer 3

The easiest way is to install MS Visual Studio Community Edition, and select Visual C++ (install anything else you want but they are all optional except C++). This will install CMake and the correct compiler and libs in the correct locations.

• Download the latest Dlib.
• CD into the Dlib folder.
• Make sure the Dlib/build folder is empty ( rm -r -force .\build* )
• Run: python .\setup.py install

If you get an error, post back here. You are probably missing a dependency or ENV variable.

Answer 4

you can also go this link (dlib.whl) and download .whl version of dlib and use this command to install it

pip install .\dlib-19.8.1-cp36-cp36m-win_amd64.whl

but you should replace name of the file in above command with any file that you have downloaded

Answer 5

I had the same problem. Installing dlib from .whl worked.

pip install https://pypi.python.org/packages/da/06/bd3e241c4eb0a662914b3b4875fc52dd176a9db0d4a2c915ac2ad8800e9e/dlib-19.7.0-cp36-cp36m-win_amd64.whl#md5=b7330a5b2d46420343fbed5df69e6a3f

Answer 6

I have just encountered the same problem yesterday and looked up many resources. And at last I solved it by installing Visual Studio 2017, choosing C++-related component, because it needs the C++ compiler to build the dlib.
