Rust bootstrap fails on Windows

help
#1

I wanted to make a contribution to Rust, but when I tried running the python x.py script (I've tried build src/libcore among others), I receive the following error:

thread 'main' panicked at '
command did not execute successfully, got: exit code: 1

I'm trying to compile on Windows using Visual Studio 16 2019. I've tried running with administrator privileges but to no avail and tried both with and without the vcvars64.bat batch script. Does anyone have any other recommendations?

#2

Do you have cmake installed ok? If not the the docs have Windows instructions.

You should never need admin to build rustc.

#3

Yes, I have CMake installed. The CMake config runs just fine. At some point after that it seems to run the aforementioned batch script

#4

Unfortunately the backtrace doesn't give a lot to go on. It only says that running cmake.exe failed (it returned 1) but not why. Is there any output from cmake before that?

My only other suggestion is to double check in the VS Installer that you've got the C++ Visual Studio workload installed and that it does include things like the Windows 10 SDK and the Universal CRT. But I am just wildly guessing.

#5

Sorry. For completeness, here is the entire output log:
