Compile errors on Windows environment

[Elimiriel]

0. environment_win.yml should be downloaded manually, and the requirements could be installed manually
At the first trial the file was auto-generated, but after some times it doesn't be generated. After reading that, I can tried in Anaconda environment+manual installation of modules in yml.
1. About initial environment settings
The code also requires 'utils' and 'case-insensitive-dictionary' module. Be aware: 'case_insensitive_dict' doesn't work even thought their names are similar.
2. While running build0.bat: A syntax warning kicks into.
C:\ProgramData\lpython\lpython\src\libasr\wasm_instructions_visitor.py:174: SyntaxWarning: invalid escape sequence '\.' splitted_name = re.split("[\._]", func)
It was possible to solve that correct as r"[\._]"
3. While running build1.bat: A fail, lots of C4xxx warnings about possible loss of data, stop of ninja by subcommand failure
3.1 Fail

Additional info: LLVM 19.1.0 RC4 is connected by a plugin with my MSVS.

I have encoutered the same problem, how did you solve them.

I have encoutered the same problem, how did you solve them.

I couldn't solve this issue myself for now. And I think issue 2 could be solved by using os.curdir, os.rep and vice versa when cleaning up installation scripts.

You can install it like we do at the CI:

lpython/.github/workflows/CI.yml

Line 83 in 7eb2bea

xonsh ci/build.xsh

, which is well tested and it works.

Alternatively, use WSL and build it in Ubuntu, which is also tested and works.

@Elimiriel the error you are getting is:

C:\ProgramData\lpython\lpython\src\libasr\codegen\evaluator.cpp(39): fatal error C1083: Cannot open include file: 'llvm/Transforms/IPO/PassManagerBuilder.h': No such file or directory
[60/98] Building CXX object src\libasr\CMakeFiles\asr.dir\asr_scopes.cpp.obj
cl : Command line warning D9025 : overriding '/GR' with '/GR-'

You might have the wrong LLVM version installed. The CI uses LLVM 11, so you can install that.

In LFortran we recently got all LLVM version 10-19 working, but the fixes are not yet ported to LPython. I think LPython currently works with LLVM 10-16.
