I need some help to set up clang on windows properly.
I have visual studios 2015 installed. And the Windows SDK.
I recently installed Clang, and ran a very basic hello world through it to make sure it's working correctly. And it gave me an error I can't make any sense out of.
Visual Studios will handle this just fine.
Here is the error output I've received from clang:
Microsoft Windows [Version 10.0.14393]
C:\Users\Leo>cd C:\Users\Leo\Desktop\Sandbox
C:\Users\Leo\Desktop\Sandbox>clang++ hello.cpp
In file include d from hello.cpp:1:

C:\Users\Leo\Desktop\Sandbox>
Line 1 in hello.cpp is just:
#include <iostream>
So this error isn't making sense to me.
Type echo %INCLUDE% at the command prompt. To see your INCLUDE path.
Check to make sure your INCLUDE environment variable isn't set to a path that contains a Visual Studio path. Probably will need to do the same for the LIBenvironment variable as well.
I recently got it to work correctly, and compile windows applications. Including Directx11 and Directx12.
Turns out you would need to build Clang under Visual Studios after generating a Cmake project. If you wish to default to 64bit, you need to specify the 64bit version of Visual Studios.
Once it's compiled, you need to run clang-cl under the VSbuild tools.

I've been trying to install Boost Libraries for 5 months now, yes very embarrassing, and currently this is the error I run into.
I am running this on Windows 7, 64 bit. Boost 1_59_0.
I used the Visual Studio 2013 x64 Native prompt to go to the boost directory and ran
bootstrap.bat
and then
b2 --toolset=msvc --build-type=complete architecture=x86 address-model=64 stage
However I get the error
'cl' is not recognized as an internal or external command
Following this, I ran
vsvarsall amd64
from
C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC
I went back and tried running b2 again but I got the same error as before.
I searched for "cl.exe" on my laptop and I found it here:
C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin
C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin\x86_amd64
C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin\x86_arm
C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin\amd64
C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin\amd64_arm
C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin\amd64_x86
C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\bin
C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\bin\x86_amd64
C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\bin\x86_arm
C:\Program Files (x86)\Microsoft Visual Studio 8\VC\bin
I understand that 'b2' is unable to find 'cl' and I have to give the 'path' to the 'cl.exe' but I don't know how to set path, what to type where etc. I thought that 'vsvarsall' was supposed to fix this but it didn't.
Please help.
EDIT 1:
I set path following the instructions given in the comments, but I am still getting the same errors.
In your log, you have a number of calls to "C:\Users....\b2_msvc_12.0_vcvarsall_amd64.cmd". This is a file that caches the environment that VC needs. Could you try deleting it, in case it got stale value from older version?
You need to make sure that you run vsvarsall.bat and in the same cmd window run bootstrap and b2. Since the env variables are only set for that shell. Otherwise add the paths set by vsvarsall.bat manually in environment variables for the system.
You can search your control panel to find where to set environment variables, or hit the windows key and type in environment variables. You will get a shortcut to the window for those settings.
I downloaded Visual C++ and Visual Studio, but I cannot find cl.exe to compile my C++ file. The path to the install is `C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin.
Where can I find the compiler to compile C++ code?
Visual Studio 2015 doesn't install C++ by default. You have to rerun the setup, select Modify and then check Programming Language -> C++
In Visual Studio 2019 you can find cl.exe inside
32-BIT : C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.20.27508\bin\Hostx86\x86
64-BIT : C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.20.27508\bin\Hostx64\x64
Before trying to compile either run vcvars32 for 32-Bit compilation or vcvars64 for 64-Bit.
32-BIT : "C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvars32.bat"
64-BIT : "C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvars64.bat"
If you can't find the file or the directory, try going to C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC and see if you can find a folder with a version number. If you can't, then you probably haven't installed C++ through the Visual Studio Installation yet.
For me that have Visual Studio 2015 this works:
Search this in the start menu: Developer Command Prompt for VS2015 and run the program in the search result.
You can now execute your command in it, for example: cl /?
For first need check is installed cl.exe,
open Developer Command Prompt for VS2015 and type "where cl"

problem:
I tried to compile a simple c++ source file with Microsoft Visual C++ 2010 Compiler,
and I encountered an error.
I've installed Microsoft Visual C++ 2010 and MinGW and located the windows.h file,
I've also configured the directory of extra files in Code::Blocks.
code:
#include <stdio.h>
#include <stdlib.h>
#include <windows.h>
int main(){
printf("Hello World!");
getchar();
}
error:
F:\test2.cpp(3) : fatal error C1083: Cannot open include file: 'windows.h': No such file or directory
In order to utilize multiple compilers when using the Code::Blocks IDE, you need to ensure that the settings for each compiler are properly configured. These may be accessed via the Settings->Compiler menu option.
After selecting the compiler that one wishes to configure, you need to select the Search Directories tab and ensure that the Compiler, Linker and Resource Compiler tabs contain appropriate folders.
Each tab will possibly need several folders entered into the search box.
Using the example of the Visual Studio C++ 2010 compiler, each tab will contain a reference to both
the appropriate folder, as found in the install location of VS
the appropriate folder, as found in the install location of the
Platform SDK
In my case, the folder locations are:
Compiler
C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\include
C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\include
Linker
C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\lib
C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\lib
Resource Compiler
C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\include
C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\include
For some purpose that is not really important I used MSVC 2012 in console mode (Windows 8x64) and when I tried to compile "Hello, World!" it didn't find its stabdard library and linker couldn't find some of its lib-files. So in the end I managed to configure both compile and link commands to make them work properly:
"C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin\cl.exe" -c main.cpp /I
"C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\include"
and for link:
"C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin\link.exe"
main.obj
/LIBPATH:"C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\lib"
/LIBPATH:"C:\Program Files (x86)\Windows Kits\8.1\Lib\winv6.3\um\x86"
To sum up I want to know, how can they be configured so that cl found its headers and link found those libs. Please consider that I'm going to use them in Qt Creator, where they don't work and I've just found a way of getting them to work but from outside of Creator and I need to do it by Creators' means (nmake or jom options that is).
You need to call
call %ProgramFiles(x86)%\Microsoft Visual Studio 12.0\VC\vcvarsall.bat
in your command line window. This sets up a usable environment.

I am trying to run a program called minimal.c. When I type at the command line:

I have gone and made sure windows.h is in the directory. I'm setting the path too. It's
in C:\Program Files (x86)\Microsoft Visual Studio 8\VC\PlatformSDK\Include.
I have Visual Studio 2005.
I have exhausted all possibilities. Any ideas?
You could also run the vcvars32.bat file from the directory C:\Program Files\Microsoft Visual Studio 8\VC\bin (this is in your path) prior to your cl command.
Like this:
C:\Users\nathan\Desktop>vcvars32
C:\Users\nathan\Desktop>cl minimal.c
vcvars32 calls C:\Program Files\Microsoft Visual Studio 8\Common7\Tools\vsvars32.bat which sets up the required environment for compiling and linking.
The environment variables are INCLUDE, LIB, and PATH.
The compiler looks for header files in the INCLUDE path during compile, and libraries are fetched from the LIB path during link.
For me, with Visual Studio 2017,
"C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\Tools\vsdevcmd.bat"
is the command to use before compiling with cl.
Here is the documentation.
When you started the command line, did you run the included command line shortcut that comes with the Visual Studio setup? This will set the correct environment variables for you so that the compilation will work correctly.
In your project folder, open a PowerShell window and run:
cmd /c 'call "C:\Program Files (x86)\Microsoft Visual Studio\2019\BuildTools\VC\Auxiliary\Build\vcvars64.bat" && cl minimal.c '
You've added your INCLUDE paths to your PATH environment variable. Use vcvars32.bat as the others have suggested.
Your path variable might be too long. Windows can’t take more than 1023 characters in the PATH environment variable.
I had the same issue getting the
fatal error C1034: stdio.h: no include path set
and after running the C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Auxiliary\Build>vcvars64.bat cmd/batch script would get the
fatal error C1083: Cannot open include file: 'stdio.h': No such file or directory
error message. From here, and other posts on that page, I suspected that the Windows 10 SDK package must be installed. After installation and running the vcvars64.bat script from the path mentioned above, the problem was solved.
P.S. As explained here, an alternative to manually finding and running the above cmd/batch script, you may just do +Q and search for Developer Command Prompt for ..., in my case it is Developer Command Prompt for VS 2022.
if you have version 2017 of the compiler cl.exe (you installed Visual Studio 2017), in the command prompt you need go to "C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\VC\Auxiliary\Build" and run 'vcvars32.bat' for x86 compilation or vcvars64.bat for x64 compilation.
