V not able to find C:\Program Files\Windows Kits\10\Lib

[thisisleobro]

I am using gcc version 7.3.0 (i686-posix-dwarf-rev0, Built by MinGW-W64 project) on windows10x86

I cloned the repo and executed make on the folder expecting it to compile the v compiler but got the following output:

Building V
Cloning vc...

Attempting to build v.c with GCC...
 > Compiling with .\v.exe self

Failed to compile - Create an issue at 'https://github.com/vlang/v' with the following info:

cannot compile `C:\Users\user\STAGE\v\cmd\tools\vself.v`:
V panic: ls() couldnt open dir "C:\Program Files\Windows Kits\10\Lib": directory does not exist
print_backtrace_skipping_top_frames is not implemented

Exiting from error

I have clang and gcc installed but not msvc

I was not sure i should open an issue since it is probably the branche where the work is being done but anyway

Executing make a second time gives the following output:

Building V

The problem seems to be "C:\Program Files\Windows Kits\10\Lib" not existing which is weird since this path seems to be msvc only.

First thing to try might be to get a newer version of gcc. I have

gcc.exe (MinGW-W64 x86_64-posix-seh, built by Brecht Sanders) 10.1.0

and I'm not seeing any issues compiling v.

I think the only way you could experience this error is if you used to have a Windows SDK installed, but manually removed it. Check the Registry at this path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Kits\Installed Roots. You should see a KitsRoot10 REG_SZ C:\Program Files\Windows Kits\10\ in there, which reports a kit that doesn't exist. Removing that key/value pair may resolve the issue.

Where did you get that version? I am using the compiler that came with qt so i am not sure how to update

I did that and now i get

apparently v was compiled but when i run "v" i get:

For usage information, quit V REPL and run `v help`
cannot compile `C:\Users\user\STAGE\v\cmd\tools\vrepl.v`:
V panic: ls() couldnt open dir "Lib": directory does not exist

Runnig "v help" gets me what seems to be the right output tho but still cant compile example tho

$v examples\cli.v

print_backtrace_skipping_top_frames is not implemented

I got gcc from http://winlibs.com/

I got gcc from http://winlibs.com/

It still doesnt compile. I will point out again that i am compiling with the 32 bit toolchain. I would like to know if anybody was able to compile for x86 on windows and if it is supported

[JalonSolov]

That page has both 32-bit and 64-bit versions of gcc and other tools.

I haven't had a 32-bit version of Windows for years, so sorry, I can't help you. Hopefully someone else here can.

@thisisleobro, latest version seems to do the job

I did manage to build v.exe too but does it compiles the examples?

Depends on whether you have met all the required dependencies/requirements. For example, if you try to build the UI samples and your graphics driver does not support the minimum OpenGL version required, it will not work. The same is true if you try the Sqlite examples but don't have the development headers installed, and so on.

i am aware of that but are you able to build something that does have no external dependencies like fizz_buzz

[Ekopalypse]

Yes, that's not a problem.
