Problems generating solution for VS 2017 with CMake

Question

So I installed Visual Studio 2017 yesterday. I also installed CMake 3.7.2 which supports VS 2017.

My VS installation is with the Game development with C++ workflow + a few other components:

I've also added the CMake stuff (but I don't think I even needed it - since I'm using CMake as a standalone tool to just generate the VS solutions) and MSBuild (I had msbuild.exe even before adding that component - so not sure what exactly does that additional component do).

With VS 2015 I was able to just run cmake . from a normal command prompt for a solution.

With VS 2017 the workflow changes - I've read this post from Microsoft.

So I tried the following:

• I opened the Developer Command Prompt for VS 2017 and from it I ran cmake . -G "NMake Makefiles". Then running cmake --build . compiled everything properly.

• When I tried the following in the prompt: cmake . -G "Visual Studio 15 2017 Win64" to force the creation of a solution I got the following errors:

  -- The C compiler identification is unknown
  -- The CXX compiler identification is unknown
  CMake Error at CMakeLists.txt:3 (project):
    No CMAKE_C_COMPILER could be found.
  CMake Error at CMakeLists.txt:3 (project):
    No CMAKE_CXX_COMPILER could be found.
  -- Configuring incomplete, errors occurred!
  

I also tried setting up the environment using vswhere.exe and running vcvarsall.bat like this:

"C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Auxiliary\Build\vcvarsall.bat" amd64

and again I could only generate NMake files and not a solution.

So how can I get a solution?

And why does cl.exe report Version 19.10.25017 when it's in VC\Tools\MSVC\14.10.25017\bin?

Answer 1

Turning my comments into an answer

The error -- The CXX compiler identification is unknown - No CMAKE_CXX_COMPILER could be found. basically means that CMake wasn't able to compile a simple test program (which it always does as part of identifying/validating the compiler).

You can take a look into CMakeFiles\CMakeError.log (relative to your binary output directory), the error reason should be in there.

Two possible reasons I came across so far:

1. Missing administrator rights. You can try running this again from a shell that has administrative rights to crosscheck if your Visual Studio was setup with the need for administrator rights.

2. Missing Windows SDK. Verify your SDK installation e.g. check that you have any Resource Compiler installed. It should be in a path similar to:

   C:\Program Files (x86)\Microsoft SDKs\Windows\v[some version]\bin\RC.Exe
   

Visual Studio 2017 Installation

Please note the Visual Studio may not install all necessary C++ packages even when you select one of the C++ pre-defined packages (as I have e.g. used Desktop development with C++ and then added more packages under the Individual Components tab).

Here is which selection worked for me (VS2017 Community Edition, Windows 10):

If you have projects using MFC/ATL libraries you need to add it under SDKs, libraries, and frameworks subcategory:

References

• CMake Error at CMakeLists.txt:30 (project): No CMAKE_C_COMPILER could be found
• The CXX compiler identification is unknown
• VS 2010 and CMake: 'rc' is not recognized as an internal or external command

Answer 2

I'm using Windows 7.... And after @Florian told me in the comments to look into CMakeFiles/CMakeError.log I managed to fix the problem!

Here is the first log:

It seemed I needed Windows SDK version 8.1 so I installed it as a component (had only version 10 installed). But then there was another error:

So LINK : fatal error LNK1104: cannot open file 'ucrtd.lib' sounds a lot like I needed to install more components - and so I did:

• Visual C++ runtime for UWP
• Windows Universal CRT SDK

And after that the problem is gone!

Answer 3

If you have the Windows 10 Creator's Update SDK installed, it doesn't install the desktop binaries by default, in order to keep the installation size down. CMake will always try to use the latest SDK when it compiles, which will fail as it will be missing binaries such as "gdi32.lib" (that's the first error that occurs for me).

Microsoft list this as a "Known Issue", see Visual C++ Desktop Known Issues.

The Windows 10 Creators Update SDK has been refactored to reduce installation footprint by default. When you Install this SDK via the UWP workload, it will not install the headers/libs required for Win32 C++ Desktop Projects.

In order to fix the problem, you need to modify the Visual Studio installation to include the Windows 10 SDK (10.0.15063.0) for Desktop component.

Answer 4

Can tell my experience. After reading CMakeFiles/CMakeError.log found an error

LINK : fatal error LNK1104: cannot open file 'MSVCRTD.lib'

and what's more important - warning

Common7\IDE\VC\VCTargets\Microsoft.CppBuild.targets(402,5):
warning MSB8038: Spectre mitigation is enabled but Spectre mitigated libraries
are not found.
Verify that the Visual Studio Workload includes the Spectre mitigated libraries.  

Option 1: I have no intention to use "Spectre-mitigated" libraries and want just to restore previous build behavior.

That means that we need to turn off generating Visual Studio project with correspondent compilation flags on by default since CMake does that to check whether compiler exists and operational.

Luckily found a thread on support forum: https://developercommunity.visualstudio.com/content/problem/348985/installing-wdk-1809-enabled-spectre-mitigation-fla.html

Solution is not very elegant, but works. Put/copy file with name 'Directory.Build.props' to /build folder with content:

<Project>
  <PropertyGroup Label="Configuration">
    <SpectreMitigation>false</SpectreMitigation>
  </PropertyGroup>
</Project>

That overrides default VS behavior and disables /QSpectre compiler switch.

Now CMake's compiler test run passes and no other issues found.

Option 2: ensure that Spectre mitigation libraries installed

Answer 5

I encountered a similar problem.

It was solved by first un-checking "Desktop Development with C++", and then re-checking "Desktop Development with C++".

Answer 6

Windows 10.0.17134 Build 17134; Visual Studio 2017 Community (15.9.7)

All required components are installed

In my case (Wireshark building), an error was in the wrong toolset. CMake determines v141 while the actual version is v140.

cmake -G "Visual Studio 15 2017" -T v140,host=x64 ..

Answer 7

For me ,I installed vs2015 before,and the c compiler 2015 work before,when i install vs2017, get the same error can't find compiler. And when i run cmake .. in the vs2017 developer command,it works. And i can specify generetor to vs2015 or vs2017,it all works.

Answer 8

From my experience the "base" of this CMake workflow problem is the (in this case) really misleading error message "No CMAKE_C[XX]_COMPILER could be found."

CMakeError.log is the key: I saw "...Cl.exe /c..." there, so the compiler was found (and executed)

My problem was a missing ucrt.lib (although the Win10 SDK was there; copied, not "installed", my fault).
